The Power Failure Message. See Figure 3.

The Power Fail message occurs whenever the power has been
interrupted or turned off to the dispenser. If the power is turned off and
the P Fail message does not appear, the charge is low on the 12-volt
battery. Failure of the battery could result in loss of dispenser
electronic totals and stand alone operating data.

an error code. If one is present, refer to the section in this manual
entitled “How to Use Diagnostics,”

How to Read the Electro-mechanical Totalizer

The dispenser is equipped with a Electro-mechanical totalizer for each

hose which records the volume dispensed for each sale. The volume
recorded is an accumulative total that cannot be reset. The electro-
mechanical totalizers are located at the top of the main display aligned
above each Individual Price Per Volume Display. The total is
cumulative and reads in whole unit (gallon or liter) increments. See
Figure 3.

Note: Because of rounding methods used and the nature of electronic

totals versus an analog device such as an electro-mechanical totalizer,
electronic totals and electro-mechanical totals will rarely match exactly.

 How to Read the Last Sale During a Power Failure
If an A.C. power failure occurs, the dispenser will display the last sale in
progress at the time of the failure. This display will alternate with the “Power
Fail Message” (PPPPPP). This will continue for 15 minutes after the
dispenser has lost power. If power is returned, the display will go back to it’s
normal display.

NOTE: The battery will display data for 15 minutes. Fig. 1

Example : The customer is dispensing fuel and the dispenser / site looses
power. The customer has pumped $7.50 to this point. See Figure 1. At this
point the dispenser valve closes and the customer cannot continue fueling.
The display will continue to alternate between showing the amount (along
with the volume amount) and the Power Fail message for 15 minutes. After
the 15 minutes if power is still out, the display goes blank until power is

 Default Settings
The 3000 Series electronic dispenser can be ordered with the Local
Preset option. The Local Preset is used in countries where there is an
attendant at the pump to dispense fuel for the customer. The attendant
can select “volume” (gallons or liters etc..) OR currency (dollars, pesos
etc..) and preset the amount of fuel for the customer. Once the
dispensed amount reaches the preset amount the sale stops. An
example of what the dispenser might look like is shown in Figure 1.

The local preset overlay is shown in Figure 2. This keypad has two
functions:

uses Local Preset Keypad/
2. To program the dispenser
Overlay for each hose.
When you have a Local Preset, this keypad takes the place of the
Manager Keypad and is used to program the dispenser. The
programming of the dispenser remains the same as with any other retail
electronic dispenser. There are no “extra” modes to program just
because you have the Local Preset option. The only difference between
the Local Preset option and a standard retail 3000 series electronic
dispenser is that a couple of the programming keys are not shown on
the keypad overlay. See Figure 3.

 How to Program Mechanical Pulse Output
There is no menu code for pulse output on the 3000 series dispenser. Instead, a Pulse Output board is
used that allows the dispenser to be connected to a Fleet System like a mechanical dispenser. The
dispenser will generate pulse and handle signals to the Fleet System. There are jumpers on this Pulse
Output Board which determine what the pulse rate will be and what the pulse width will be. This Pulse
Output board is capable of sending out pulses at the following ratios:
1:1
10:1
100:1
1000:1

Also, the pulse width selections can be set with jumpers for selections as follows:
.5 milliseconds
1 millisecond
2 millisecond
4 millisecond
8 millisecond
16 millisecond
32 millisecond
64 millisecond

Also, when using a Pulse Output board, the dispenser should be programmed for RS485 communication
(mode 21).

See the information on the following page that describes how to set up the Pulse Output Board for use
with a 3rd party Fleet System.

Downloaded from www.Manualslib.com manuals search engine

 Setting the Jumpers on the Pulse Output Board
The Pulse Output board is ordered as an option with the Electronic 3000 series. This board is where the
field wires connect the 3rd party Fleet System to the Pulse Output functions of the dispenser. This
board also has jumpers that need to be set to determine the Pulse Rate and the Pulse Width. Whatever
pulse rate is set will send the same pulse rate and width to both the Fleet System and the Tank Gauge
(if one is connected). This section describes how to set these jumpers. Refer to the Figures below:

JP1-1,2,3,4,and 5 are used to set the pulse rate and pulse width.

JP2 is currently not used.

The top left of the Pulse Output board has a

jumper header called JP1. It has 8 jumper
This is the Pulse Output Board. It has the terminal positions. You can set the Pulse Rate with the
strips for the field wire connections along the bottom first two jumpers and the Pulse Width with the

using a pump handle output signal, an authorize in-
put signal and a pulse train signal. The Jumper
Header JP1 is at the top left of the board. These
jumpers must be set to determine the pulse rate and
the pulse width. See information below.
To set the Pulse Rate Output, set jumpers JP1-1 and JP1-2 as follows:

 How to Mechanically Calibrate the SB-100 Meter
(M-Cal Option)
The Bennett SB-100 Meter is built to maintain accurate measurement under normal operating
conditions. The meter is a positive displacement device with rods and pistons, which require a break in
period. The meter is calibrated at the factory using a solvent for safety purposes, and must be
calibrated after it has been installed. We strongly suggest recalibration of the meter after a 90 day break
in period.

With the 3700 series electronic dispenser, mechanical calibration is optional. The standard 3700 is
calibrated electronically. That means that the meter in the dispenser that you have may not be able to
be calibrated mechanically (it will not have a mechanical calibration wheel). If the meter on the dispenser
that you have does not have the mechanical calibration wheel on it, you have the electronic calibration
option. Go to the next section in this manual that explains how to perform an electronic calibration.

Each SB-100 meter is provided with the following Example 1

 Electronically Calibrating the SB-100 (Standard Flow) and
FPP (High Flow) METER (E-CAL)
Electronic calibration is a simple method to calibrate the meters in the
dispenser. This method uses a mathematical algorithm in the software
to account for meter wear rather than mechanical methods to limit the
piston throw within the meter.

This method also eliminates the parts associated with mechanical

calibration in the meter. Result is a more symmetrical meter that will be
intrinsically more accurate.

Follow these steps to electronically calibrate the meter: Fig. 1 - Open the upper door.
Step 1 - Pump 5 gallons as displayed on the dispenser display into your
test can. Make sure to stop pumping at exactly 5.000 gallons.

Step 2 - Read the plus / minus value in the test can.

Step 3 - Unlock and open the electronics door on the side with the
meter that you want to calibrate (See Figure 1). IMPORTANT - Make
sure you are calibrating the correct meter! To make sure, locate the
meter you are working on and the valve that is connected to it. Follow
those valve wires to the correct CPU/Control Board to ensure you are Fig. 2 - Pump your sample into
electronically calibrating the correct meter. With the power on, locate a certified test can.
the electronic calibration switch on the top of the CPU/Display board
(mounted to the door) See Figure 3.

Step 4 - Break the seal and move the switch to the calibrate position.
Close the door and you should see the display read the current
calibration value.

Step 5 - Press the “Enter” button along the top edge of the CPU/Display
board. See Figure 6. Figure 6 shows that there are 3 buttons nest to the
electronic calibration switch. The functions of the buttons are “Enter”,
“Up”, and “Down”. You will be using these buttons to enter electronic

 System Operation - Overview
Basic System Theory of Operation - Please refer to the figure on the previous page

110 volts A.C. OR 230 Volts A.C. single phase from the main service panel connects to the main power
connector on TS2 of the CPU/Display/Power Supply Board (from this point on to be referred to as the
CPU board). L1 comes in on terminal 2 of TS2 and L2 (230 volt system ) or Neutral (120 volt system)
comes in on terminal 1. The other terminals on this terminal strip will be discussed later. There are no
jumpers or switches that need to be set for different input power. Incoming power can range from 270
volts A.C. to 85 volts A.C.

The power signal then passes through fuse F1 which is a replaceable 3 amp slow blow fuse on the
CPU. The A.C. power is then routed through a filter section to eliminate noise spikes and to change the
AC voltage over to various D.C. voltages. The DC voltages created are +24, +12 and +5 volts DC. The
voltages are used for the following within the dispenser:

A. +24 volts - Backlighting, satellite board and valve power

B. +12 Volts - CPU display, relay for motor power, RS485 Communication power, pulsers and
electromechanical totalizer
C. +5 Volts - System voltage for circuit logic.

There are no test points or adjustments for these voltages. The only voltage you can measure is the
incoming voltage on TS2. The incoming voltage range can be anywhere from 85 - 270 Volts AC.

Programming the Dispenser - Programming of the dispenser is done through the use of the Manager
Keypad or Local Preset keypad (if you have that option) that is shipped with each dispenser. This
keypad is normally disconnected and stored in the head of the dispenser when not being used. When
using the Manager keypad, connect the ribbon cable that comes with it to the Manager Keypad and plug
the other end into J3 of the CPU board. Make sure that the handle is hung up and the dispenser power
is on. Refer to the Operator section of this manual to see how to program the dispenser.

Main CPU Board - The CPU board is mounted to the upper electronic door. There is one CPU per
hose. The dispenser can have 1, 2 or up to 4 hoses. This means there could be 1, 2 or up to 4 CPUs
installed. This series of dispenser does not support multiple products or hoses per CPU. There is only
one CPU per hose. This series of dispenser does not offer blending or credit card readers / printers. The
Main CPU board performs the following functions:

1. Acts as the power supply, converting AC voltage into various DC voltages.

2. Contains all of the programming, diagnostic and electronic totals information.
3. Communicates with the handle and pulser through the intrinsically safe barrier circuit.
4. Communicates with a Console if there is one using either current loop or RS485 communications.
5. Communicates with a Pulse Output board (optional) if the system is connected to a Fleet Control
System.
6. Controls the suction pump motor (self contained system) OR remote submerged pump motor
control.
7. Communicates with the Satellite Board if this is a Master / Satellite Truck Stop installation.
8. Communicates with the Auxiliary Display board if there is one.
9. Controls the 2 stage valve
10. Performs all the mathematical calculations for converting volume to money.
11. Contains the electronic calibration values. Is used to input the electronic calibration values.
12. Contains the system software.
13. Contains the battery backup to supply display information for 15 minutes after system looses power.

 System Operation - Overview
Satellite Board (Optional) - The 3000 series supports Truck Stop Master / Satellite installations. The
Master unit contains the CPU and display electronics along with a high flow meter and pulser, and the
satellite unit contains only a handle switch, valve. Hose and nozzle. All flow goes through the Master
meter / pulser and is piped to “Tee” to both the master outlet and the satellite unit.. The Satellite board
is located directly beneath the CPU on the door and is connected to the CPU on CPU connector J5.
The satellite board is where the field wires from the satellite unit connect. The wires that connect to the
satellite board are:
1. Three field wires from the satellite valve.
2. Two signal wires from the “in use” light if that option was purchased.
3. Two handle switch wires from the Satellite unit handle circuit.

There is also a jumper on the Satellite board to select either exclusive or simultaneous fueling operation.
Also, the CPU provides power to the satellite through connector J5.

Intrinsically Safe Barrier Modules - The Intrinsically safe barrier modules provide protection to the
handle and pulser circuits located in the lower half of the dispenser in the hydraulic area. These circuits
are designed with fuses and zener diodes to prevent any potential energy from entering the hydraulic
area so that under no condition will there be enough energy to create an electrical “spark”. This way,
there can be no explosion if there are vapors. There is one ISB for each CPU. If there are 2 CPU’s or
more, these ISB modules are identical and can be interchanged with one another for troubleshooting
purposes. The boards are identical. The fuses on these boards cannot be replaced in the field as a UL
requirement. These boards are covered with a metal cover to protect the circuits from an inadvertent
short and the covers must always be in place when the dispenser is in operation.

Dual Phase Pulsers (Standard Flow) - 3000 series pulsers are dual phase electronics pulsers that
pulse at a rate of 1024 pulses per gallon. These pulsers are physically mounted to the output shaft of the
Bennett SB-100 meter. As fuel flows through the meter, the output shaft rotates and turns the pulser.
Approximately 8 rotations of the meter represents 1 gallon of fuel. The pulser is an optically coupled
device and outputs 2 separate phases of square wave pulses through a ribbon cable connection, where
it connects through the “flame deck” to the ISB for that side. The pulsers operate off a regulated +5volt
dc signal that was created from a +12volt supply. When the valves are closed and there is no fuel flow,
there should be no pulses output from the pulser. The pulser only generates pulses as it is turning. As it
turns and generates pulses, it sends these pulses to the CPU board through the ISB for that hose. The
CPU counts the pulses and performs the mathematical computations to covert this information to a
display readout that shows the volume and it’s computed currency value on the main display. The CPU
and the pulser works in conjunction with one and another. For example, when the CPU receives it’s first
9 pulses, it opens up the slow flow portion of the 2 stage valve. At this point the CPU is making sure that
both phases of the pulser are working. If one of the phases of the pulser is not working, the dispenser
will never come out of slow flow and will go into an error condition. After 9 good pulses are received, the
system opens up the high flow portion of the 2 stage valve. Generally, a retail dispenser in fast flow puts
out a maximum of 10-12 gallons per minute maximum due to state and federal regulations. There is one
pulser for every meter.

Error checking - The dual phase pulsers allow for error checking. One phase is used to check the
other. For example, after pumping 1 gallon of fuel the CPU should see approximately 1024 pulses from
each phase. There is a built in diagnostic where if the CPU sees more than 15 consecutive missing
pulses from one or the other of the phases it will stop the sale and post an error message on the display
of the side of the dispenser with the error. Errors are stored in a diagnostic history file and any error
that occurs can be cleared by removing and replacing the hose from the nozzle boot.

SB-100 Meter - The standard flow Bennett meter which uses 4 piston, cam and diaphragm. This device
measures the fuel and has the dual phase pulser physically attached to the output shaft. As the fuel
flows through the meter the shaft turns in relation to the amount of fuel passing through it. This meter
can be ordered with mechanical calibration or without it. If it is ordered without it, electronic calibration
must be used.

 System Operation - Overview
High Flow Meter and Pulser - The high flow meter / pulser are contained in a single unit. You cannot
replace one without the other. They are contained in a single housing. This meter is referred to as the
“High Flow” meter and is used in the “Little Squirt” and “Big Squirt” dispensers for higher flow rates. This
meter / pulser assembly is electronically calibrated in the field using the e-cal switch on the CPU board.
Refer to the Electronic Calibration portion of this manual for further details.

Handle Switch - The handle switch allow the system to know when the customer wants to dispense
and signals the CPU to turn on the pump motor. The handle switch uses a “reed” style proximity switch
and magnet to signal when the nozzle has been removed from the boot. In the nozzle boot there is a lift
lever . Attached to this is a magnetic pickup. When the lift lever is raised, the magnet moves in proximity
to a reed switch on the handle circuit board. When this happens, the reed switch is pulled in completing
the circuit. This circuit is electrically “Open” when the nozzle is in the boot, and it is electrically “Closed”
when the lever is lifted. The CPU knows that the handle has been lifted when it sees it go from open to
closed. The CPU then sends a +12 volt dc signal to a relay to turn on the motor. When the handle is
returned to the nozzle boot the CPU turns off the pump motor and signals that the sale is complete and
the CPU sends this information to the Point of Sale device (or Fleet system if there is one).

Valve control - The dispenser may or may not have a valve/s, depending on which model has been
ordered. If there is, the CPU also controls the valve. The hose will have a “2” stage valve. The valve is
there to control product flowing through a hose. It prevents the unauthorized dispensing from a hose that
isn’t authorized. It is also used to slow down the flow towards the end of a pre-pay or preset sale. The 2
stage valve operates off +24 volts dc. If the system uses a valve, there is one valve on the output of
every meter.

Note - For the Satellite unit in a Master / Satellite high flow system, the valve in the satellite operates off
of 120 volts A.C.. However, the valve in the Master unit operates off of +24 volts D.C.

2 Stage Valve Control (Theory) - On a two stage valve, there are 2 “stages”, slow flow and fast flow.
When the handle is lifted the CPU should turn on the motor and turn on the valve. At the beginning of
the fuel transaction, as previously mentioned, the slow flow portion of the valve opens first for the
product and the CPU starts counting pulses. It only opens the slow flow portion of the valve at first after
the handle is lifted and the dispenser is authorized. After 9 good pulses are received from each phase of
the pulser it will open up the valve to the “fast” flow. The CPU does this by controlling the coils of the
solenoid of the 2 stage valve. It does this by providing the coils with a path to ground through a field
effect transistor (FET) on the CPU. The valve has 3 wires coming out of it, red, yellow and black. The
red is +24 volts, the yellow controls the slow flow coil and the black controls the fast flow coil.

System memory - A +3.3 volt dc on board battery is provided on the CPU board for maintaining system
programming in the Random Access Memory (RAM) during a power outage or anytime the system is
turned off. This battery is not replaceable.

System software - The CPU “operating program” is provided by use of an EPROM (Erase-able
programmable read only memory). This EPROM determines the functions that are available on the
dispenser.

The Main Display - The main display is used for the customer to view the currency and volume amount
of the sale as well as display current fuel prices. It is also used to house the electromechanical
totalizers. The display gets its information from the CPU.

Main Display Backlighting Board - The CPU does not use lights or ballasts. To light the display it
uses a backlight board using a series of 1.5 volt Light Emitting Diodes (LED’s). By using this type of
lighting it eliminates the need to replace burnt out light bulbs and ballasts. These LED’s are powered
from +24 volts it receives from the CPU.

 System Operation - Overview
Auxiliary Display Board - The dispenser may or may not have an auxiliary display on the opposite side
from the CPU side. The auxiliary display is normally only used on dispensers with side mounted nozzle
boots so that a product can be pumped from either side of the dispenser using the same hose. The
auxiliary display plugs into the CPU, is mounted on the opposite side of the dispenser and simply
repeats (indicates) the same information that the CPU displays. The Auxiliary display also has a
backlight board which allows the information to be read in dim or dark situations.

Pulse Output Board (Optional) - A pulse output board is used to tie the electronic dispenser to a Fleet
Management system. It can also be tied to a Tank Gauge. The pulse output board is also tied to the
CPU board using RS485 communication. The pulse output board is used to route a handle signal to tell
the Fleet System that the hose is “in use”, and the pulse output board also sends D.C. pulse information
to the Fleet System so that it can count the volume being dispensed. The pulse output board also is
used to receive “authorization” signals from the Fleet System. Without this “Authorization” the hose CPU
will not reset and will not pump. The “authorization” is in the form of 120 Volts A.C. to the terminal strip
on the pulse output board.

The output pulse ratios available are 1000:1, 100:1, 10:1 and 1:1. This can be set with jumpers on the
Pulse Output board. Also, the pulse width is selectable from .5 milliseconds to 64 milliseconds.

Satellite Board (Optional) - With Master / Satellite truck stop applications (high flow), a satellite board
is used to control the valve in the satellite unit and to receive handle signal from the satellite unit. This
board is located in the Master unit and the field wires to the valve and handle from the satellite connect
here. Also, an “in use” light option may be ordered so that when the satellite handle is raised, the light
on the outside of the upper electronics on the Master will light (a requirement in some states).

 Turning Power “On” to the Dispenser
The dispenser power must be turned on from the breaker panel.

Locate the breaker panel that serves the dispenser that you want to turn on.

Move the breaker to the “On” position. You should see the display displaying the last sale on each CPU
and auxiliary display. See figure 1. If there has been no sales, all 000’s will be displayed. See figure 2.

Fig. 1 - Normal display Fig. 2 - Main display and Aux

display.

If the System Looses Power

If the system experiences a power fail, there are batteries on the CPU board that will display the amount
of the last sale in progress at the time of power loss, and will alternate with the power fail message for
15 minutes (or unless the battery is over-ridden). After 15 minutes the display goes blank and stays that
way power is restored.

Battery Override Switch

When you turn power off to the dispenser and you see the power fail message (all PPP’s), and you do
not want to wait 15 minutes until the display goes blank, you can over ride the battery by pressing the
battery over ride switch located in the center of the CPU board on the backside. You should not perform
service work until the battery is off. Press this button and hold it for 1 second and this over-rides the
battery. See Fig. 4

Fig. 3 - Power fail message all Fig. 4 - To override the battery,

888’s on display indicated press the battery override
power failure to the system. switch.

Testing the Battery

The only way to test the back up battery is to turn power off to the system. It should hold the display up
for 15 minutes. If it does not, it could be because this is a brand new dispenser and needs 24 hours to
fully charge. If not, the batteries cannot be replaced, the entire CPU must be replaced.

 Normal Fueling Transaction
(This example shows a “volume only” dispenser).
1. The dispenser power is on and the nozzle is hung up. It is “idle”. See Figure 1.

2. The customer removes the nozzle and lifts the lever. See Figure 2.

3. If the dispenser is under the control of a console or a Fleet system it waits for authorization. Once
the authorization signal is received, the dispenser resets. See Figure 4.

4. Customer puts the nozzle in the vehicle. See Figure 3.

5. If the dispenser is in stand alone, the dispenser resets. See Figure 4.

6. After the reset ( all 888’s on the display for 1 second - See Figure 4), the display (money / volume)
starts at all 000’s (See Figure 5) and as soon as fuel flows, the display begins counting.

7. If the dispenser has a preset amount set either at the dispenser local preset, or a preset was set at
the console, or the Fleet System card used had a maximum amount, the customer can pump until
that amount is reached. Or, he can stop when he is done fueling. The total amount is shown in the
display. See Figure 6.

8. Otherwise, when the customer is done, he removes the nozzle from the vehicle and lowers the hose
handle. This marks the end of that transaction and the sale stops and comes “due” for collection.

The power signal then passes through fuse F1 which is a replaceable 3
amp slow blow fuse on the CPU. The A.C. power is then routed through
a filter section to eliminate electrical noise spikes and to change the AC
voltage over to various D.C. voltages. The DC voltages created are
+24, +12 and +5 volts DC. The voltages are used for the following

C)+5 Volts - System voltage for circuit logic.

There are no test points or adjustments for these voltages. The only
voltage you can measure is the incoming voltage on TS2. The incoming
voltage range can be anywhere from 85 - 270 Volts AC.

Measuring Voltage - Set your multimeter for the AC voltage range.

Put your black lead on TS2 terminal 1 and your red lead on TS2
terminal 2 to measure incoming voltage. The voltage reading should be
between 85 - 270 Volts A.C. See Figure 4.

Testing the System Fuse - The system fuse on the CPU board is
located right behind input power terminal strip TS2. Turn off power to
the dispenser. Set your multimeter for “Ohms”. Leave the fuse in place.
Put the black lead on one side of the fuse and the red lead on the other
side of the fuse. If the fuse is good, it should read as a “short circuit”.
This indicates “continuity”. Your meter may “beep”. If the fuse reading
is anything other than 0 Ohms, replace the fuse with a known
good 3 amp slow blow fuse. See Figure 5.

RAM Clear Procedure - Sometimes it may be necessary to clear the

“RAM” (Random Access Memory) of the CPU board. The RAM clear
procedure on the CPU is through software. Mode 83 is used to clear the
memory. This mode will reset most programming modes to factory set-
tings. It will NOT clear out Electronic Totals and it will NOT clear out
Electronic Calibration Values. See Figures 3, 4 and 5.

If the system that you are working on has a CPU with a fault that will not
allow you to get into Manager Mode, you will not be able to perform a Fig. 3 - Menu Code 83
RAM clear.

Connect the Manager Keypad to J3 of the CPU. Press and hold both
the “Clear” and “Enter” button simultaneously for 3 seconds until you
see “Code 00”.

Go to mode 3 to enter the security code by pressing the “3” and then
the “Mode” button. Enter the security code and then press “clear”. Fig. 4 - When you see this
press “1” to RAM clear.
To clear the RAM go to mode 83 by pressing the “8”, “3” and then
“Mode” button. Press “1”. You will see what is in Figure 4. Press
“Enter” and the system clears the RAM and reboots. During the reboot
process, the software ID shows up in the display. See Figure 5. After
the reboot, the system automatically returns to the normal operating
mode. You will need to return to Manager Mode to check your settings
and make any changes that are necessary. For example, after a “RAM
Clear”, it will be necessary to reprogram prices in mode 4 (or prices
could be sent from the control console). Fig. 5 - Software ID

J3 - Manager Keypad
The Manager Keypad is used to program the 3000 series retail
dispenser. If the dispenser has the local preset, you use the local preset
to program the dispenser. This keypad is shipped with each dispenser.
When you need to program the CPU, you simply plug it into the J3
connector on the back of the CPU. You can do this with the dispenser
power on. See Figure 1.

Refer to the Operators portion of this manual to learn how to program

the CPU. Here is a quick list of the menu codes that can be

J3 - Intrinsically Safe Barrier Circuit - The intrinsically safe barrier

(ISB) circuit connects the CPU to the Handle and Pulser circuits that
are located in the lower half of the dispenser. See Figure 3. There is
one ISB module for each CPU. That means the dispenser may have 1,
2, or 4 Barrier circuits. See Figure 5. The purpose of this circuit is to
limit the amount of voltage/current going to those electronic
components in the lower half (area where explosive vapors might be) of
the dispenser. This circuit ensures that there is not enough electrical
current to create a spark that could cause an explosion. See flow chart: Fig. 2 - Half “moon” indent

Current Loop communication uses the standard Bennett Protocol using 2

choice, the dispenser should be set for “Current Loop” in mode 21 and a
Bennett model 515 interface box would be used.

RS485 communication is for consoles that write the simple Bennett 485
command set. There would be no interface box necessary and mode 21 at the
dispenser would be set for RS485. RS485 communications is also used when
you have a Pulse Output Board connected to the CPU.

CPU Jumpers
Connector TS1 on the CPU is where the field wiring be-
tween the dispenser and the console would connect. This
dispenser can communicate two different ways, either Cur-
rent Loop OR RS485. Refer to the installation drawings for
the two styles in the back of this manual. Also, see the
drawings above for a quick understanding.

Also note that jumpers JP2, JP3, JP4 and JP5 have their
jumpers set across their top two pins for “current loop” com-
munications and across the bottom two pins for “RS485”
style communications. Set these jumpers across the bottom
pins also when using a Pulse Output Board (since the CPU
communicates with the Pulse Output Board using RS485
communications.)

 Setting the Jumpers on the Pulse Output Board
The Pulse Output board is ordered as an option with the 3000 series. This board is where the field wires
connect the 3rd party Fleet System to the Pulse Output functions of the dispenser. This board also has
jumpers that need to be set to determine the Pulse Rate and the Pulse Width. Whatever pulse rate is set
will send the same pulse rate and width to both the Fleet System and the Tank Gauge (if one is con-
nected). This section describes how to set these jumpers. Refer to the Figures below:

JP1-1,2,3,4,and 5 are used to set the pulse rate

and pulse width.
JP2 Not Used

The top left of the pulse output board has a

jumper header called JP1. It has 8 jumper po-
sitions. You can set the pulse Rate with the
first two jumpers and the pulse Width with the
3rd, 4th and 5th. See information below.

This is the Pulse Output Board. It has the terminal Other Jumper Settings on Pulse Output

 Testing the Handle Switch Signal
Figure 1 shows the Pulse Output board. In the center on the bottom is
TS2. This is the terminal strip that the handle signal to the Fleet system
connects to.

Step 1 - Remove the field wires from the terminal strip and mark them
so that you will put them back on the same terminals when you are
finished. See Figure 2.

Step 2 - With the fueling point handle in the “OFF” position, use your
multi meter and measure the “resistance” across the handle channel Fig. 1
you are testing on TS2. This example shows side 2 handle being
tested. With the handle “OFF” the LED above the relay should be
“OFF” and the resistance reading should be “Open” (O.L. means Open
Loop) See Figure 3.

Step 3 - Lift the handle that you want to test. The LED above the relay
should come on. See Figure 4. The resistance shown on your meter
should show 0 ohms (dead short). This means that the relay is closed.
See Figure 5.

Step 4 - De-activate the handle and make sure that the LED turns off Fig. 2
and that the relay opens. See Figure 3.

Step 5 - Reconnect the field wires to terminal strip TS2.

This test should be run if the Fleet System is not receiving the handle
signal. If this test passes but the Fleet System does not signal “in use”,
contact either Bennett Technical Support or the Fleet System
manufacturer for assistance.

 Testing the Authorization Circuit
A simple voltage measurement can be used to test for the presence or
absence of the authorization signal. Also, the LED D3 (side 1) OR D6
(side 2) can tell you if the channel has received the signal. To run the
voltage test:

Step 1 - On TS3 of the Pulse Output board, on the channel (side 1 or

side 2) that you want to test, use your multi-meter, set it for the AC
voltage scale (you will be looking for 120 volts) and place your leads
across the terminals of the channel that you are testing.
Fig. 1
Step 2 - When no authorization is present you should see 0 volts or
some small stray voltage like you see in Figure 1. Figure 1 shows a
small stray voltage of .387 volts A.C. Fig.2 - LED D3 (side 1) or D6
(side 2) will turn on when
Step 3 - Go through the steps necessary to authorize this fueling point receiving the authorization
at the Fleet System (Use card, select pump etc..) signal.

Step 4 - You should see the LED come on for the side that is receiving
authorization. See Figure 2.

Step 5 - Use your volt meter to measure the A.C. voltage. It should
show 120 volts (+/- 10%). See Figure 3. This is the authorization signal.

Step 6 - Lower the handle and notice how the LED light goes out. That
means that the authorization was removed.

Cross Phasing - The term “Cross Phasing” refers to a situation where an improper wiring practice
results in damage or potential damage to the dispenser electronics. It occurs when two or more remote

As long as both dispensers are on the same phase L1 (both) OR L2 (both) you do not have a cross
phasing situation. But, if you have dispenser 1 on phase 1 (L1) and dispenser 2 on phase 2 (L2), and
both these signals are sent to the same point in the relay box, then the result is 120 volts + 120 volts =
240 volts being fed back on those same wires being fed back to the dispenser which could damage the
dispenser electronics. In most cases, it blows the 3 amp fuse on the CPU.

In the last few years, relay boxes have been designed to eliminate this cross phasing problem so this
problem is not as prevalent as it used to be.

How to Check for Cross Phasing - If you go to the main power panel
that serves the dispensers you should see each dispenser being fed by
it’s own breaker (or maybe two dispensers on one breaker). In any
case, to tell if the dispensers are on the same phase you will need your
voltmeter and access to the power panel.

WARNING - Voltages present in the Main Service Panel can cause

death or serious bodily injury. You must be trained on taking
voltage measurements to perform this test.
Fig. 1 - In phase
Step 1 - Remove Power Panel Cover

Step 2 - Locate the dispenser power circuits

Step 3 - Using your volt meter on the AC voltage scale (you may see
voltage as high as 250 volts), put the red lead on the power wire
feeding one dispenser and put the black meter lead on another
dispenser power circuit. See Figure 1.

Step 4 - Determine if it is cross phased or not - If both dispensers are

on the same phase of power, your meter should show 0 volts. See
Figure 1. If they are cross phased you will see 240 volts. See Figure 2. Fig. 2 - Cross Phased

If you determine that the dispensers are cross phased you should
contact the installer to have him fix the problem. When the dispenser is
cross phased it will blow the fuse on the CPU. This is a 3 amp slow
blow fuse. Do not bother replacing the fuse until the problem has been
resolved or else it will just blow another fuse.

Measuring voltage to the submerged pump motor - When you

measure the two phases of power going out to the submerged pump
motor you should see 240 volts. Refer to Figure 3.

WARNING - Voltages present in the Main Service Panel can cause pump motor power - 2 phase

Master / Satellite Truck Stop Applications -

The 3000 series can accommodate truck stop applications where you
have a “Master” dispenser along with “Satellite” dispensers.

Truck stops use this to fill up tanks on both sides of the vehicle (see
Figure 2). Also, truck stops normally offer faster flow rates since the
vehicles tend to be much larger. A typical truck stop dispenser can dis-
penser between 40 and 60 gallons per minute depending on whether
only one side is fueling or both sides are fueling.

photo and the CPU is on the right.

Auxiliary Display - On certain models of two sided dispensers, the display/ CPU board mounted on the
upper doors may not be a CPU board. It may be just an Auxiliary display board. An Auxiliary display
board connects to the CPU on the other side of the dispenser with a ribbon cable between the two
boards. On the CPU, the Auxiliary Display board connects to J1.

The function of the Auxiliary Display board is to show the customer the sales information on the other
side of the dispenser on dispensers with side mounted hoses. This way, the sales information can be
viewed on either side for that hose. All displays have backlighting. The Aux board does not have any

 210 Retail Electronics - Dual Phase Pulser

Protective Dust Cover

Pulser mounted under dust cover

Meter Shaft to Pulser Coupling

Meter

Dual Phase Pulser

Theory of Operation - Dual Phase Pulsers - The 3000 series pulsers are dual phase electronics
pulsers that pulse at a rate of 1024 pulses per gallon. The “Dual Phase” design is to prevent tampering.
These pulsers are physically mounted to the output shaft of the meter. The new design also uses a dust
cover to keep dirt and such off of the pulser. As fuel flows through the meter, the output shaft rotates
and turns the pulser. Eight rotations of the meter represents one gallon of fuel.

The pulser is an optically coupled device with a spinning disk with two infrared beams and outputs 2
separate phases of square wave pulses 90 degrees out of phase with each other. We call these two
phases phase 1 and phase 2 or “Leading” and “Lagging” phases. These signals are routed through a
ribbon cable connection, in a daisy chain fashion where it connects through the “flame deck” to the bar-
rier board for that side. There it connects to the CPU board for processing. The pulsers operate off a
regulated +5volt dc signal that was created from a +12volt supply. When the valves are closed and there
is no fuel flow, there should be no pulses output from the pulser. The pulser only generates pulses as it
is turning. As it is turned by the output meter shaft it generates pulses, and sends these pulses to the
CPU board through the Barrier Circuit for that hose. The CPU counts the pulses and performs the
mathematical computations to covert this information to a display readout that shows the volume and it’s
corresponding computed currency value on the main display. The CPU and the pulser works in conjunc-
tion with one and another. For example, the CPU first opens the slow flow portion of the 2 stage valve.
At this point the CPU is making sure that both phases are working. If one of the phases of the pulser is
not working, the dispenser will never come out of slow flow. After 9 good pulses are received from both
phases, the system opens up the high flow portion of the 2 stage valve and full flow is achieved. Gener-
ally, a retail dispenser in fast flow puts out a maximum of 10-12 gallons per minute maximum due to
state and federal regulations.

Error checking - The dual phase pulsers allow for error checking. One phase is used to check the
other. For example, after pumping 1 gallon of fuel the CPU should see approximately 1024 pulses from
each phase. There is a built in diagnostic where if the CPU sees more than 15 consecutive missing
pulses from one or the other of the phases it will stop the sale and post an error message on the display
of the side of the dispenser with the error. Errors are stored in a diagnostic history file and any error that
occurs can be cleared by removing and replacing the hose from the nozzle boot. Also, if the pulser is
disconnected, an error will result.

The pulser information is carried on a ribbon cable that connects the pulser to the barrier circuit. This
ribbon cable connects from connector J2 of the Barrier Board, runs through a potted conduit between
the upper portion (electronics area - high voltage) section of the dispenser to the lower portion
(hydraulics area - low voltage) section of the dispenser. This ribbon cable connects to pulser connector
J2 . On the pulser, a jumper must be placed across the last set of pins on J3. See figure below.

Theory of Operation - Handle Switches - Handle switches allow the

system to know that the customer wants to dispense fuel and signals
the CPU to turn on the pump motor. The handle switch uses a “reed”
style proximity switch in conjunction with a magnet to signal when the
nozzle has been removed from the boot or when the handle has been
lifted (lift lever).

When the nozzle is removed from the nozzle boot the spring loaded
flapper moves bringing the magnet in proximity to a reed switch on the
handle circuit board. When this happens, the reed switch is pulled in Fig. 2 - This is an example of
completing a circuit. When the CPU sees the circuit go from “Open” to the “Lift Lever”.
“Closed” it knows the handle has been turned on. Then the CPU sends
the +12 volt dc signal to the relay to turn on the motor. When the Fig 3 - Reed switch S1 is

 210 Retail Electronics - Two Stage Valve
Two Stage Valve Control - The two stage valves that the 3000 series dispenser uses are +24 Volt dc
valves (except for the 120 or 230 volt valves that are used in the Satellite unit of a Master / Satellite
system). These valves are used to control the flow of fuel to the hose. In retail, where the fuel always
has a price displayed, you need valves to keep people on other dispensers from getting fuel from an
unauthorized hose when the submerged pump is “on” for that product. If valves were not present then a
customer on another pump could pump fuel from the same product hose as the one you are using
because that product submerged pump has that product line pressurized.

Also, the other use of the two stage valve is in a preset or prepay application to slow the flow of fuel at
the end of the transaction. As an example, on a pre-pay sale (where the sale amount is collected before
fueling), the pump is “preset” by the P.O.S. In this example we will say that the customer preset the
pump for $5.00. When the customer pumps fuel it is in fast flow all the way up to the slow flow offset
that is programmed in the pump. Let’s say that that was set to .2 gallons. So, at about two tenths of a
gallon until the end of the sale the pump goes into slow flow and at $5.00 the valve closes all the way
and the pump stops.

So, a retail dispenser may have only one or up to four 2 stage valves. There is one valve per meter and
the valve is mounted on the outlet of the meter.

The upper portion of the valve is where the two coils

are located along with the two plungers. The wires
that control the coils are:
Black - Fast Flow coil/plunger
Yellow– Dribble/Slow flow coil plunger
Red - +24 Volts dc

+24 Volts dc is always present on the Red wire

(unless this is a 120 or 230 volt AC valve which can
be found in the Satellite unit of a Master / Satellite
system). The coils are not energized until the system
provides a “ground” for those coils. When the CPU
wants to open either the fast or slow flow it turns on Fig 1 - 2 stage valve operation
a Field Effect Transistor (FET) to provide a ground
for that coil. Lets look at an example:
Example: With the valve turned “off” both “coils” are
de-energized because their legs are not grounded. In
the de-energized state the spring in the fast flow
valve pushes against the flanged sleeve and both
the fast and slow are dropped down closing off any
flow.
At the beginning of a sale, the CPU will allow only
slow flow until 9 pulses are received from both
phases of the pulser. It does this by grounding the
slow flow coil (energizing it raising the plunger) by
turning “on” a field effect transistor (FET). This allows
a small amount of fluid to travel through the small
orifice in the diaphragm, up along the grooves on the
outside of the high flow valve, and then down
through the little hole in the center of the high flow

meter outlet and the hose outlet.

Downloaded from www.Manualslib.com manuals search engine

 210 Retail Electronics - Two Stage Valve
When the CPU wants to open the valve all the way it
energizes the fast flow coil by doing the same thing with the
fast flow coil using it’s associated FET. The difference is
that when the fast flow opens there is enough differential
hydraulic pressure across the diaphragm to cause it to
push against the spring and allows full flow from inlet “A” to
outlet “C”. At this point the fast flow and the slow flow
plunger are energized and raised allowing fast flow. At the
end of a preset or prepay sale the fast flow FET gets turned
off, the plunger drops, causing a loss of differential
pressure across the diaphragm, closing the diaphragm and
only allows fuel flow (slow flow) through inlet “A” into orifice Fig 1 - 2 stage valve operation
“B” and through the hole in the fast flow valve and to outlet
“C” which gives you slow flow. To stop the sale entirely, the
slow flow portion of the valve is de-energized by turning off
it’s FET and closing the slow flow plunger and shutting off
all flow through the valve.

+24 volts DC is present on the red wire of the valve all the
times ( or at least it should be). When the CPU wants to
energize a coil it grounds the black or yellow wire for that
coil which allows current to flow. The CPU controls all the
solenoids of all the valves this way.

The output for all the valve is on connector J4 located on

the edge of the CPU board near the batteries. Above this
connector are the FET’s (transistors). A wiring harness Fig 2 - Valve connector off the CPU J4
connects the CPU to the valve. See figure 2.

Note: Always make sure that the correct valve is connected

to this harness my. The harness connectors are clearly
marked. See figure 8.

 210 Retail Electronics - Two Stage Valve
The two stage valves can be tested for proper voltage readings. There are two ways to do this. From
wire to wire on the top of the valve where the valve harness connects to each valve and from wire to
chassis. Refer to the table below for normal voltage readings. If you are testing a 120 or 230 volt AC
valve you can substitute 120 volts where you see 24 volts in the chart below.

 210 Retail Electronics
Testing a valve - Obviously the best way to check a valve is to pump
fuel and see if you are getting full flow. See figure 1. You can do this by
pumping into a test bucket. Normal flow at a retail location is generally
10 - 12 gallons per minute in the United States.

But what if you are not getting normal flow? Another way to test to
see if the valve is opening is by placing your hand on the solenoid
portion of the valve and pumping fuel. If the solenoids are working
properly you should feel two distinct “clicks” as the solenoids are
energized. One “click” for the slow flow and one “click” for the fast flow

pulses) See figure 2. Make sure that the small hole (this hole is in the
center of the fast flow plunger. The plunger must be removed from the
body of the coil section of the valve for inspection). in the fast flow valve
is not restricted. You can do this with by a visual inspection.

You can remove both the fast flow and the slow flow plungers from the
solenoid by unscrewing the solenoid from the valve casting and the two
plungers should slide out. Make sure the fast flow (grooves along the
sides) is the first one that comes out and that the slow flow is after that.
Be careful not to loose the spring in the slow flow plunger. See figure 3.

You can also open the valve body and check the diaphragm to make Fig 2 - Feeling the solenoid
sure that there are no loose or foreign objects, any tears in the “clicks”
diaphragm and to make sure that the spring is in place properly. See
figure 4. Always carry extra O-rings because if you open a valve that
has had fuel pass through it the O-ring will “swell” and you will not be
able to get it back in its groove.

One card reader is installed at each fueling point in the electronics

head. There can be up to 16 card readers at a typical site although
most sites use far less than this. Although the card reader is installed IN
the dispenser, it is not PART OF the dispenser. What that means is that
the card reader sits inside the dispenser, gets power from the dispenser
(+12 volts and +24 volts) but does not communicate with the dispenser.
The communication between the card reader to the Point of Sale
passes directly through the dispenser. This will be discussed in greater

From the IC box to the Ruby - From the dispensers to the IC box is
RS 485 communication which allows runs of up to 1000 feet. From the B/B Converter
IC Box to the Ruby we must change communication protocol over to
RS232 so that the Ruby can communicate with the card readers. All
Ruby com ports speak “RS232”. To do this we have a B/B converter
which converts from RS485 to RS232 protocol.

This converter connects to the top end of the fan out board with a red,

DUKPT vs. Master Session - When debit cards are used, whether at
the dispenser or inside the store, an encryption system must be in
place. The encryption system is in place to “encode” the personal
identification numbers (PIN) that the customers input at the card
readers. The reason why the pin numbers must be protected is so that
if the card is stolen or lost, it is useless without the pin and this protects
lost or stolen cards from being used. The two methods that the banking
system uses for this is called Master/Session and DUKPT encryption.

The thermal printer is also connected to the VIB through a 50 pin ribbon
cable. This cable is also for data and power.

Power and Data Cable to the VIB-

There is also a 9 pin male connector used to connect to a laptop which
can be used to load the “Bennett Signature Files”.

When the dispenser is in operation and the card reader system is

installed, the card reader gets data and power on J1 of the VIB. There
are 9 conductors on this cable. The nine pin connector J1

Orange - +24 volts power for the printer.

The middle row of this cable has another three wires. They are the
RS485 communication wires that connect the card reader com to the
DCT terminal strip on the Power Distribution board which then connects
to the field wires for the DCTs. These wires are white, brown and

Normal Transactions:
Cash Transactions -

A cash transaction is a “post pay” where the customer drives up, pumps
fuel and then pays inside the store.
The customer presses the “pay inside” button. This signals the Ruby
that the customer is requesting authorization to pump. The pump
cannot pump fuel without the authorization from the console if the pump
is in console mode.

At the Ruby this “call in” signal is represented by the flashing car icon. A
steady “Beep” is heard.

The console can be set to release or approve all of the pumps

automatically without the cashiers intervention, or the cashier can
release the pumps with the “Approve (all)” button or just the fueling
point number followed by the approve button. In this case the cashier
hits the “approve all” button. This silences the call in “Beep” and
authorizes the pump.

After receiving the authorization from the console the card reader says
something like “lift lever or select grade” (depending on whether this is
a lift lever or push to start pump). In this case we’ll say it’s a lift lever.
The customer lifts the lever…..

And selects the grade. Once the start button is pressed (or the lever is
lifted), since the pump has received authorization then the pump goes
through the segment check (all 8888’s) and then zeros the display and
displays the selected price in the price window.

The dispenser turns on the submerged pump or self contained pump
and the proper valve opens. If the nozzle is being squeezed the fuel
begins to flow.

The Ruby displays the fueling message represented by the little “Fuel
Nozzle Drop” icon. This picture also shows a “stacked” sale. ($)

At the end of the sale the nozzle is hung up which ends that sale. The
handle switch, whether it’s a lift lever or a nozzle boot switch is the
official end of the sale as far as the POS is concerned.

At the Ruby the sale “comes due” and must be cashed out. This is
represented by the $ sign for that fueling point.

Card Transactions -
Credit Only -
For a site that only accepts credit cards, the card readers that are put in
the pumps are standard Everest Plus without encryption. The card
readers were ordered for a specific network (i.e. Buypass, SPS etc.)
The IC box is a standard box with only the fan out board and the B/B.
The Ruby is programmed with the proper PAK ( i.e. AMOPAK,
SPSPAK, CITPAK etc..) for the network they are on. The Ruby has
numerous parameters that need to be set up in order to process credit
cards at the pump. This information can be found later in this section.
Also, each card reader must be programmed with a unique address and
set up for credit only. This information will also be covered later in this
session.

After all the equipment has been ordered, installed and setup properly
and if the network has the site setup for credit, here’s what happens
when a customer runs a credit card.

The “idle” message at the card reader may vary but will say something
like “press payment key or swipe card”. After pressing the “credit here”
button it will say something like “insert card”.

The card is swiped with the magnetic stripe oriented properly in the
track of the reader. When the card is swiped, the data (card number,
name and expiration date) is sent to the Ruby and then on to the
network (via phone line modem, leased line or VSAT) to check the card
for authorization (making sure the card has not reached it’s credit limit)
and the ruby sends a message to the card reader that says “one
moment please” or “processing card” while the card is being checked.

Note - Ever wonder where the “Idle Prompt” and the “Start Fueling
Prompts” come from? For a list of these prompts and how to set them,
reference Table 3 later in this section.

On the Ruby the icon that shows the credit card is being used is the
little “car” symbol (not flashing). This tells the cashier that a credit card
is being used at that fueling point. The cashier does not usually have to
release the pump on a credit card sale.

 VeriFone Card Reader Interface
Credit Only (continued)
After the card gets authorized from the network, the Ruby sends down
a message to the card reader display that may say something like “Lift
Lever and Select Grade”

The customer removes the hose and lifts the lever (on a lift lever pump)

At the end of the sale the nozzle is hung up which ends that sale. The
handle switch, whether it’s a lift lever or a nozzle boot switch is the
official end of the sale as far as the POS is concerned.

The customer cannot remove the nozzle and continue to pump until the
whole authorization process begins again. At this point the message
sent down from the Ruby might say “would you like a receipt” and the
customer would press “yes” or “no” on the card reader.

If he presses yes, the receipt would print and the customer would
remove it. Duplicate receipts cannot be printed at the card reader, only
at the POS.

Card Transactions -
Debit Transactions -
The debit transaction works much the same way as any other credit
card transaction with one exception. When the debit card user swipes
their card at the dispenser, the Ruby sees it as a debit type card and
sends down a prompt message to “Enter Pin”.

Injection of the Card Readers -The keypad injection encodes the pin
number information before it is sent to the POS. The POS forwards this
encoded pin number to the bank where it is decoded and verified. If it is
a good pin then the bank authorizes the card and the Ruby releases the
pump. All other parts of a debit transaction are the same. A debit card transaction
requires the customer to enter
The card reader itself is also a little different from a standard credit card his Personal Identification
reader in that it has been specially “injected” (from Bennett) with the Number
proper encryption code for this network. This will be covered later in this
section.

Here is an example of an Everest terminal that is encrypted for Phillips

and DUKPT. This card reader would not work at any other site other
than a Phillips 66 trying to use DUKPT encrypted debit.

How do you check to see if you have the right card reader? You can
find a sticker on the card reader unit that says what type it is. If you
can’t find the sticker contact Technical Support.
Card readers have a sticker
that describes the oil company/

Programming the card reader -
For Credit Only Dispensers

Make sure the dispenser is powered on and that the card reader display
is on. It will probably say “out of service”.

Service Tip! When programming the card readers at the site for the
first time, it is likely that they all have the same address of “1”. For this
reason it may be a good idea to disconnect the card reader field wires
from terminal strip on the deck so that all the card readers with the
same address do not lock up the system. After the dispenser has been
properly addressed you can re-connect the field wires.

Entering the password:

Step 1 - On the card reader keypad, press the “1” and “Enter” button
simultaneously twice. It should say “Function Config”.

Step 2 - The top right hand key is the right arrow and the left top key is
the left arrow and the center key is the Accept key. Press the Accept
key (top center). It should say “Type”.

Step 3 - Press Accept again and it should say “Type”.

Here is where we choose either “Debit”, “No Debit” or MSM. Right
arrow until you see “No Debit” and press “Accept”. It should say “No
Debit Set”.

Step 4 - Press “CLEAR” to get back to the main menu. Then, right
arrow until it says “Key Type”. You do not have to program this because
we are not running debit so we don’t need an encryption “Key”. Press
the right arrow until it says “Poll” and press “Accept”. Here is where we
have to give the card reader an address so that the Ruby knows which
one it is talking to. The choice here is either “MSM” or “CAT”. We are
not concerned with the MSM address here because we are not running

Loading the Ruby using Gemstall -

The technician will be responsible for checking out both ends of the
system all the way from the Bennett pumps to the VeriFone Ruby
system. It is highly recommended that the technician attend Bennett
Dispenser Training as well as VeriFone Ruby Training. This manual
attempts to assist the Technician in understanding how the Ruby works
with the Bennett pumps. However, as the Ruby software changes it
may make some of the material in this manual obsolete.

To program a Ruby to work with the Everest Card Readers in the

Bennett Horizon 2 dispenser, there are programming parameters that
must be set up when you load the Ruby using Gemstall as well as
programming the Ruby after the operating system (AMOPAK, CITPAK,
SPSPAK etc..). Here are some of the things that you have to make sure
of when you load the operating program on the Ruby.

Connecting your laptop to the ruby -

(Assuming that you have all the files you need loaded on your laptop…)

Step 1 - Make sure you have the files you need on the laptop. Check Use the rs232 cable with the
with Bennett Technical Support to see if the version of the “PAK” that null adapter for the com port
you want to load on the Ruby meets the minimum requirements to work on your laptop
with the Everest Card Readers for the network you are on and the Oil
Company that it is for.

Step 2 - Connect the rs232 cable to your com port on the laptop with
the proper null adapter. With the power off to the Ruby plug the other
end into com port 1 of the Ruby. Turn the Ruby power back on.

Connect the other end to Com

1 of the Ruby. Make sure
power is off to the Ruby before
doing this step.

Loading the Ruby using Gemstall (cont’d) -

Step 3 - Put the Ruby in ‘Boot-up Monitor” by using a paper clip and
pushing it in the pin hole closest to the front of the Ruby on the right
hand side. This must be done for the Ruby to accept the loading of an
operating system. You will hear the system make an audible tone and
after a moment a message comes on the Ruby that says “ Select a Yes
key No double wide keys”. Leave the ruby alone, don’t hit any keys. It
will stay this way until you have downloaded the new operating system.

Step 4 - Run Gemstall on your laptop. Gemstall is VeriFone's menu Putting the Ruby in Boot Up
drive utility that you use to load the operating system. It guides you monitor
through the installation process.

Step 5 - When Gemstall opens up you will have a menu. (At this point
this manual will not cover every step to load a Ruby, only the ones
pertaining to the Bennett Fuel protocol and the Bennett Card Reader
protocol) Select the “PAK” you want to load. .

Step 6 - Select the fuel type protocol. Use Bennett for your fuel
selection. Make sure it is on the correct port (usually defaults to com
port 6).

Make sure you check your settings for the fuel protocol. It should be
Bennett on com 6.

Step 7 - Select the Card Reader Protocol. Surprise! We use Dresser /

Wayne protocol for the Everest Card Readers on the Bennett Horizon
2. The code was written to use Wayne, so for the Everest Card
Readers use Dresser/Wayne not Bennett.
There are exceptions to this. Call Tech Support if necessary.

Use the default settings on com port 9 for the card readers. If this com
port is taken or bad you can use another com port on the Ruby, just
make sure you connect the rs232 cable coming from the IC Box to the
right port on the Ruby.

Step 8 - Selecting Wayne Keypad - The keypad file you select for
Wayne is important. If you don’t select the right keypad, then the keys
on the card reader won’t work properly. See Table 1 quick reference list
of the proper keypad files for the different overlays that are available on
the card readers.

Here is one type of overlay that matches the W1032 keypad file. There
may be several overlays that match the keypad file.

Step 8 - Selecting the Wayne Prompt - This is the prompt that the
customer sees first on the Card Reader Display.

Programming the Ruby to work with the Everest Card Reader -

The Ruby system must be programmed to work with the card readers.
There are numerous settings that, if not programmed correctly, will
cause the Ruby to not communicate with the card readers. Not all of the
Ruby parameters will be covered here, only the ones that affect the
operation of the fuel and card system. If the parameter you are looking
for is not mentioned in this section then the default setting is probably
alright to use.

Most of the parameters that need to be programmed can be found in

Fuel Manager. To get to Fuel Manager from the main sales screen (this
must be done on the Master Ruby not the satellites) press “exit” and
then the right arrow key until you get to “Fuel Manager”. Press Enter.
Enter password.

Sending Changes to the Pumps and DCRs - Whenever you make

changes or if these are the last changes that are being made before
exiting Fuel Manager, run the “Initialize Fuel” function to send the
changes to the pumps and run the “Initialize DCRs” function to send the
changes to the DCR’s.

The ones most important are:
1) Attributes - Pump Number

Access -Yes– Has to be turned on to be assigned fuel products. This is

the parameter that when set to “yes” lights up the fueling point number
on the ruby fuel screen.

Blend Type - The 3000 series does not offer blending.

After setting up your first fueling point, copy the remaining fueling points
to set them up the same.

2) Hose Assignments - Set fuel products from lowest grade to the left
to highest grade to the right. Exception: On a 3+1 dispenser, the diesel
product will be the first hose. If this setting is wrong, the prices for the
products will appear in the wrong windows.

Fuel Prices - You must have prices for the fuel to be able to run a sale
on a Bennett pump. Either the prices can come down from the Ruby or
can be set manually at the pump.

Note– The “Enable DCR Y/N” parameter in Configuration/Credit Card

Configuration in Network Manager determines whether a credit card is
accepted at the pump DCR. However, this setting is controlled by the
network. If the network decides to turn off this setting, the Parameter

1) DCR Attributes:
Select DCR Number

DCR in Dispenser - Yes. The pump has a card reader or “No” the
pump doesn’t have a card reader. Must be set to Yes.

DCR out of service - No. Normal setting when the DCR is running with
the Ruby or “Yes” if the card reader is malfunctioning and needs to be
taken off line. When this is set to yes, a message appears on the DCR
telling the customer to pay inside. The card reader and the receipt
printer are disabled.

Pay at the Pump - Yes. The pump has a card reader and is available
for use by the customer. If this is set to “No” then the customer cannot
pay for fuel at the dispenser. This is different from the DCR in
Dispenser attribute in that this setting when turned to “No” will still allow
the card reader to display messages whereas the DCR in dispenser
when turned to “No” will say “Out of Service”

Push to Start - Set to “No” if the pump has a lever that must be raised
to begin fueling. This setting ensures that the correct instructions are
being displayed ON THE DCR. All 3000 series dispensers have “lift to
start” levers.

Grade Select Button - The 3000 series does not have grade select
buttons. The lift lever is used to initiate the sale.

Upgrading the Everest Card Reader Software in the Field -

It is possible to update the card reader software in the field using a

laptop computer and a special cable that plugs into the VeriFone
Interface Board in the pump.

This upgrade is required if:

1)Any of the card reader software levels do not match
2)To bring the card readers up to the latest level of software
3)Anytime you get a message on the card reader display that says
“Download Needed”.

Periodically VeriFone, who makes the card readers, offers newer

software. We load this software onto the card readers at the factory. If
we send a card reader to a site that has other card readers at different
software levels then a software compatibility problem may arise.

All software should match on all the card readers or you could have
problems at the site.

To load the software onto the card readers you will need the following:
1)Software Files (version) Kit contains software and
2)Cable for laptop to VIB cable. You provide the
3)Laptop laptop. Kit P/N #107099
To load the software onto the card readers, follow these steps:

You need to reload the files if you ever see the message “Download
Needed”. This means that the files have been lost. See figure for
example.

Step 1 - Reboot the dispenser and view what the current software
version level is. There are currently 3 versions in the field
A)Version 1.01.02
B)Version 1.02.02
C)Version 1.02.03 (latest as of this printing)

Make sure that the version you are going to load is a later version than
what is currently at the site.

Step 2 - Power down the dispenser, override the battery open the upper
door (electronics) and then connect one end of the cable to the
VeriFone Interface Board.

Step 3 - Connect the other end of the cable to your laptop.

 VeriFone Card Reader Interface
Step 4 - Locate the files in the folder where you moved them when you
ordered the kit. The should be a batch file called
“Download” (download.exe). This is the program that you run and it will
run the download once we have prepared the card reader in the next
step. DO NOT double click on the file yet.

Step 5 - Disconnect the DCT field wires from the field wire terminal strip
on the deck. This will keep all the other dispensers from locking up if
the card reader you are working on gets an address that is already
programmed on another card reader.

Step 6 - At the card reader, with the card reader powered up, press the
“7” and “ENTER” button simultaneously to get in the “Backdoor”.

Step 7 - The card reader should say “PSWD”. Enter the password 1 6 6
8 3 1. Press the “ENTER” button. Press the “ACCEPT” button.

Step 8 - It should say Function “Download”?. Press “Accept”. It should

say “Port 1”. Hit the right arrow key until it says “Port 2”. It should say
“Unit Receive” “Autobaud Check” * - Now the card reader is ready for
the download.

Step 9 - Start the download by double clicking on the “Download” file.

This batch program automatically runs the program. It only takes 15
seconds or so for it to load the card reader with the new software.

Step 10 - You should see the card reader accepting the download. The
display will show Beneve.Out and the status line will show the progress.
There are approximately 60 packets that get sent.

Step 11 - You can also view the computer screen. It should open Com
1 and show 100% Beneve.out and sending closing packet. This means
the download was successful.

At this point you are done with this card reader. You can disconnect
your cable from the card reader. You will need to re-program the card
reader for the address and type and key type as covered previously in
this chapter. Before you finish this dispenser make sure that you
reconnect the field wires to the terminal strip that you disconnected in
step 5.

 Troubleshooting
This section of the manual was designed to break down individual problems with the most common
symptoms and corrective actions. This information comes directly from the Help Desk at Bennett from
problems that have been seen in the field.

It is difficult to foresee all problems, and in some cases, multiple problems exist that the technician has
to overcome. This is the challenge. This is where a technician with a good overall understanding of all
the equipment at the site is needed. Not only is it important to have a good fundamental understanding
of how the dispenser operates, but also, knowing the console, fleet system, leak detection equipment,
power system and general electronics and electrical wiring background are useful tools for the
technician.

This section is broken down in a table that lists “Symptoms”, “Possible Causes” and “corrective
Actions”. It is worded in such a way as the average technician can understand.

Note - The “Possible Causes” section of the table is not listed by what should be checked first or is most
common in all cases. But rather, a technician should try to locate their particular problem in the table and
then examine ALL of the possible problems and corrective actions and ask themselves “What makes the
most sense in this case”?

This manual is not intended to replace technical training. All Bennett technicians should be formally
trained. This manual is only used as a tool to help the technician after they have forgotten everything he
learned from the Home study course.

Only certified Bennett technicians should troubleshoot and service the 3000 series dispenser. Only
certified technicians should work on this equipment during the warranty period. Only certified technicians
will be helped by the Bennett Help Desk. For technical training information please contact the Technical
Services Department at 1-800-423-6638.

Finally, always remember - SAFETY FIRST! When you are working at a station, and you are most likely
working alone, watch your back! Be careful. Your safety is your own responsibility. You are working
around dangerous electrical voltages, explosive vapors and dangerous drivers. Once again, be careful!

made, remove the quick disconnect terminal strip from the
board and inspect for damage. If necessary, replace the
terminal strip.
CPU If this is a startup, and all the above checks have been
made, replace the CPU with a known good one. Also, check
for cross phasing before replacing CPU.

Submerged pump Submerged pump has power but fails to operate. Trouble
shoot the submerged pump or check for closed valve in the
product pipe line
Submerged pump If the submerged pump is tied to an electronic leak detector,
maybe the electronic leak detector has the submerged pump
disabled due to an alarm condition.
Shear valve is closed Check the shear (impact) valve under the dispenser on the
product line that you are testing. Open valve and retest.
Filter totally clogged A lot of times a new site will have a lot of debris caught in a

Isolation valve in the piping system is There may be an isolation valve in the submerged pump
closed manhole, or in the under dispenser piping sump. Open the
valve and retest.
Hose in wrong boot Is the hose in the correct nozzle boot? Sometimes the hose
is hung up in the wrong nozzle.
Valve problem Is the CPU addressed correctly if there is a pulse output
board installed? Refer to the Operators portion of this
manual for proper programming. Check mode 21.
Valve problem Is the valve properly connected to the CPU? If this is a
Master / Satellite site, has the valve connection been moved
to the Satellite board for the Master? If not, move the valve
from the CPU connection J4 and connect it on the satellite
board J2 (make sure power is off to the dispenser before you
do this!)
Storage tank has no fuel Store Manager needs to order fuel
Valve Problem It is possible that the valve is bad, but, before you replace it,
make sure the cable from the valve is properly connected to
the CPU (or satellite board as previously discussed) and that
you run a voltage test as described in the “valve trouble
shooting “ section.
Handle Switch Problem Has the dispenser reset? If the dispenser has not reset,
make sure the handle is working. Run diagnostics mode 5 to
make sure the handle switch is functioning. The valve won’t
open unless the dispenser has reset (all 888’s at the
beginning of the sale)
Nozzle Bad nozzle or breakaway. Replace as necessary

 Troubleshooting
Symptom Possible Cause Corrective Action
No Fuel coming out of Hose hung up in wrong nozzle boot Some people see the external filter closest to the front of the
hose (cont’d) dispenser on the low hose and think that that is the hose for
that product. In reality that hose goes to the other side of the
dispenser. Put hoses in the proper boots and retest. This
happen more than people like to admit.
Slow Flow from the hose Pulser Remember, the pulser must output 9 good pulses from both
phases before the CPU opens the fast flow portion of the 2
stage valve. Move a known good pulser to this position and
retest. Warning! Never disconnect or reconnect a pulser
from the circuit with power on. Damage to the pulser will
occur.
Check Valve If the hose stays in slow flow, it is possible that the check
valve may be faulty. Replace the check valve with a known
good check valve and retest.
Valve It is possible that the valve may be faulty. Check to make
sure the valve connection is connected correctly. Run a
valve test with your meter. If voltages are there, replace the
valve with a known good valve.
Filter Clogged Replace the filter with a clean filter

Leak detector tripped Check your line leak detector. You may have a leak in the
line that has tripped the leak detector.
Nozzle or Breakaway Bad nozzle or breakaway. Replace as necessary.
Valve problem Is the valve properly connected to the CPU? If this is a
Master / Satellite site, has the valve connection been moved
to the Satellite board for the Master? If not, move the valve
from the CPU connection J4 and connect it on the satellite
board J2 (make sure power is off to the dispenser before you
do this!)
System does not “Reset” Handle Switch Check your handle switch. Is the jumper on the handle
switch in the proper position? Are the handle switch wires
connected properly (refer to the Handle Switch section of this
manual).
Programming Problem if using Pulse Make sure mode 21 is set for RS485 and that if there are 2
Output CPU’s or more, that mode 22 is set for the correct address.
The P.O.B. needs to talk to each CPU, so therefore, each
CPU should be addressed properly. Make sure product 1
CPU is set for address 1 and CPU 2 is set for address 2 (if
there is more than 1 CPU in the dispenser.
Intrinsically Safe Barrier It is possible the barrier circuit is bad. This is why the handle
isn’t being recognized. Move a known good barrier circuit to
this position and retest.
No Price in Price Window If the hose does not have a price the pump will not reset. Go
to mode 4 and set a price if all else fails.
No authorization from Console If the system is programmed for Current Loop or RS 485 in
mode 21 and no authorization is received the pump will not
reset. Check mode 21 to make sure it is programmed
correctly.
Wiring problem If the unit is in Current Loop OR RS485 mode, it is possible
that the polarity of the wiring is reversed. This would explain
why the authorization signal is not being received from the
console. Check the actual wiring against the installation
drawing in the back of this manual. It is also possible that
one or more of the wires has come loose from the terminal
strip. Check this as well.
RAM corrupted It is possible that the RAM needs to be cleared. Go to mode
83 and perform a RAM clear procedure and retest. Some
system programming will be needed to be rechecked after
the RAM clear.
CPU problem If all of the above has been checked, it is possible that the
CPU is the problem. Replace with a known good CPU and
retest.

Software If the software chip was just replaced you may have bent a
pin on the chip. Remove the software and check for bent
pins or the software chip was put in backwards.
CPU The CPU can fail in such a way as to show continual resets.
RAM clear before you replace the CPU with a known good

Intermittent AC Power It is possible that the power supplying the unit is bad. Call
Bennett Technical Support 1-800-423-6638
Electronic Noise There is a possibility that electrical noise is being fed back to
the CPU through the field wires from the motor control signal
from the submerged pump relay boxes because the RC
Networks are not installed in the relay box.
Electronic Noise If this is a suction system and the suction pump motor wires
are run in the same conduit as the electronics power, make
sure the motor power IS ON OPPOSITE PHASE FROM THE
DISPENSER ELECTRONICS or else electrical noise
interference will be transmitted onto the electronics wiring
causing all kinds of electronic problems.
Can’t get past security Someone changed the dispenser On this dispenser you cannot change the pass code without
mode 03 pass code knowing the current pass code, that is, unless you know the
“back door” way which will be explained here. To do this, you
will have to break the seal on the ecal switch, so be prepared
for that. Throw the ecal switch to the “On” position. This
brings you to mode 27. Make sure the manager keypad is
connected. Press “Clear” on the keypad, this brings you to
“Code 00” on the display. At this point you can go to mode 3
and change the value to a new security code. Warning -
Never change the pass code from the factory default for this
very reason.

STP (sub pump) control Wiring problem “Chatter” is when a stray voltage or current is sent across the
relay chatters coil of the relay, not enough to pull in the coil but enough to
“almost” pull it in. This condition results in a condition where
the contacts get pulled in a little and released on and off
continually. It sounds like “chatter”. This is where it gets it’s
name. The CPU sends the relay a 120 volt “motor out” signal
to the relay. The dispenser does not send out a leakage
current or voltage so there should be no chatter caused by
the dispenser. So, if there is a stray voltage, there is a
problem in the wiring and must be diagnosed by a competent
electrician. A possible solution to this is to run a 2K ohm
“bleed” resistor across the coil in the relay to bleed this
voltage around the coil.
Valve Chatter CPU The valve is directly controlled with +24 volts DC from the
CPU board connection. If the valve is “chattering” check the

red wires from the valve are going to the correct pins on the
connector. If they look good, replace the CPU.

a preset. A fleet system card can have a maximum limit.
These are all examples. If you have a preset set and the

 Electronically Calibrating the SB100 (Standard Flow)
and FPP (High Flow Meter (ECal)
How to set the Electronic Calibration - Electronic calibration is a
simple method to calibrate the meters in the dispenser. Electronic
calibration is the same for either the standard flow SB-100 meter or the
high flow FPP meter. This method uses a mathematical algorithm in
the software to account for meter wear rather than mechanical methods
to limit the piston throw within the meter.

This method also eliminates the parts associated with mechanical

calibration in the meter. The result is a more symmetrical meter that
will be intrinsically more accurate. Fig. 1 - Open the upper door.

Follow these steps to electronically calibrate the meter:

Step 1 - Pump 5 gallons or 20 liters (standard SB-100 meter) OR 50

gallons (high flow FPP meter) as displayed on the dispenser display
into your CERTIFIED TEST CAN. Make sure to stop pumping at exactly
the desired amount. See Fig. 2.
Step 2 - Read the plus / minus value in the test can.
Step 3 - Unlock and open the electronics door on the side with the
meter that you want to calibrate (See Figure 1). IMPORTANT - Make
sure you are calibrating the correct meter! To make sure, locate the Fig. 2 - Pump your sample into a
meter you are working on and the valve that is connected to it. Follow certified test can.
those valve wires to the correct CPU/Control Board to ensure you are
electronically calibrating the correct meter. With the power on, locate
the electronic calibration switch on the top of the CPU/Display board
(mounted to the door) See Figure 3.
Step 4 - Break the seal and move the switch to the calibrate position.
Close the door.
Step 5 - The display should say “TstCAn”. Use the manager keypad to
input the size of the sample (test can size) that you took. If you have a
5 gallon sample enter 5.0. If you have a 20 liter sample enter 20.0. In
this example we will say we used a 5 gallon sample. See Fig. 4 Fig. 3 - Remove the seal and turn the

display should say “Err in”. This is asking you for the error in cubic
inches as measured in the test can. Normally the test can is calibrated
in “cubic Inches”. Enter the amount that your test sample was either
”over” or “under” the “0” mark on the can. If your sample was “above”
you would enter a “positive” value. If your sample was “lower” or
“Below” the test can “0” mark, you would enter a “negative” or (-) sign.
You do this by pressing the +/- button on the manager Keypad. If you
have a Local Preset the buttons are located behind the overlay. See
