WARNING
THIS EQUIPMENT CONTAINS LETHAL VOLTAGE LEVELS. INSTALLATION AND SERVICING
MUST BE PERFORMED BY QUALIFIED PERSONNEL

IMPORTANT: SAVE THESE INSTRUCTIONS!

READ AND FOLLOW ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING, OR
SERVICING CHARGER. ANY DEVIATION CAN CAUSE SERIOUS AND PERMANENT DAMAGE.
FAILURE TO FOLLOW THE INSTRUCTIONS VOIDS THE WARRANTY.

1. Install and ground the charger in accordance with the National Electric Code and your local electric
code. Failure to properly ground the charger could result in a fatal electric shock.

2. To reduce the risk of fire, install chargers on a surface of non-combustible material, such as concrete,
stone, brick or grounded metal.

3. This charger has been designed to only charge flooded, lead-acid batteries. It should not be used for
charging other types of flooded batteries or sealed batteries.

4. Connect only batteries of the same number of cells and ampere-hour rating as listed on the charger
nameplate. Damage to the battery could occur, particularly if the battery has fewer cells than the
rating of the charger.
◌ੰ‫ލ‬
5. Do not touch uninsulated parts of the output connector or battery terminals. A possibility of serious
electrical shock exists.

6. During charge, batteries produce hydrogen gas, which can explode if ignited. Never smoke, use an
open flame, or create sparks in the vicinity of the battery. Ventilate well when the battery is in an
enclosed space.

7. Do not connect or disconnect the battery plug while the charger is on. Doing so will cause arching
and burning of the connector resulting in charger damage or battery explosion.

8. Lead-acid batteries contain sulfuric acid, which is caustic and can cause chemical burns to the skin.
Refer to the battery manufacturers instructions for safe handling of batteries. Use proper personnel
protective equipment. Do not get in eyes, on skin, or on clothing. In cases of contact with eyes, flush
immediately with clean water for 15 minutes. Seek medical attention immediately.

9. Do not operate the charger with the door open or with any panels removed. De-energize all AC and
DC power connections before servicing the charger.

10. The charger is not for outdoor use. Do not expose the charger to water spray, rain or snow.

11. Do not operate the charger with damaged cables, including cables with exposed conductors or

SECTION 1 - INSTALLATION

1.1. Receiving

Immediately upon receipt of the charger, check it against the shipping invoice to ensure the shipment is
complete and undamaged.

Examine the outside of the packing for signs of rough handling before accepting the charger from the
carrier.

If there is evidence of damage, the receipt should be signed, and both copies (carrier's and receiving
copies) marked "Shipment Received Damaged". The carrier's representative should be called
immediately and asked to make a "Carrier's Damage Report".

If concealed damage is later detected, the carrier should be called and requested to make a "Carrier's
Inspection for Concealed Damage Report".

After inspection by the carrier, arrangements should be made with the charger representative to have
the charger repaired before placing it in service.

When contacting your charger representative for assistance on a damage claim or shipment error,
provide the Model, and Serial Number of the charger, and a full description of the damage or error.

It is good practice to move the charger to the installation site before uncrating. When using bars,
hammers, etc. for uncrating, use care to avoid damage to the charger.

WARNING: To reduce the risk of fire, install the battery charger on a non-combustible surface
such as concrete, stone, brick, or steel. DO NOT operate the charger on its shipping skid
materials.

1.2. Location

For the best operating conditions and longest life, take care in selecting an installation site. Avoid
locations exposed to high humidity, temperature extremes or dust. Moisture condensing on machine
parts and electrical components can cause corrosion, which seriously affects operation, efficiency and
life. All units are designed for floor mounting. Standard cases may be stack-mounted if required, up to 3
high. If so, optional stacking brackets are required and available. Consult factory.

Dust and dirt will also decrease heat radiation from heat-generating components, such as transformers and
diodes. This will result in higher operating temperatures and shorter life. Adequate air circulation is needed at
all times in order to ensure proper operation. Provide a minimum of 6 inches of free air space at the sides and
rear of the charger. The front of the charger must remain unobstructed for serviceability.

1.3. Line Voltage Adjustments

All chargers are shipped with the AC line voltage jumper wires set for the AC voltage specified on the
purchase order. Before connecting the charger to the AC service, it should be verified that the internal
AC voltage connections match the available AC service voltage. If necessary change the AC voltage
jumper wires shown in Figs. 1.3.1 through 1.3.3.

NOTE: For 50 Hz. Single or three phase fixed voltage chargers, there are no adjustments.

CAUTION: It will be necessary in most cases to change the AC fuses when the AC voltage jumpers
are changed. Refer to the fuse chart on the inside door of the charger for the correct fuse rating.

5
NOTE: When a 120/208/240 AC input unit is set for 120VAC a fuse neutral (brass tube) is required in the
Line 2 (neutral) fuse position.

For voltages up to 240, use a 240 volt disconnect switch.

For voltages greater than 240 to 600, use a 600 volt disconnect switch.

• Two conductors and ground wire required for single phase.

• Three conductors and ground wire required for three-phase

1.5. Connecting AC Service to the Charger

1.5.1 Single-Phase Models

Connect the AC service to the L1 and L2 terminals located at the end of the AC fuse block.

Note: If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input
wires will be connected to the L1 and L3 terminals at the top of the switch body.

1.5.2 Three-Phase Models

Connect the AC service to the L1, L2 and L3 terminals located at the end of the AC fuse block.

Note: If the charger has been ordered with an AC input door-mounted disconnect switch, the AC input wires
will be connected to the L1, L2 and L3 terminals at the top of the switch body.

7
1.6 Grounding the Charger

The charger must be grounded to the AC system ground for personnel safety.

The green ground wire in the AC input wiring must be connected to the charger ground stud
(identified by a green dot and ground symbol).

1.7 Battery Connector and Charging Cable

Verify that the connectors on both the battery and the charger are attached so that the positive
output terminal of the charger is connected to the positive battery terminal.

CAUTION: If the polarity is reversed, the DC fuse will blow.

If in doubt, check the polarity with a DC voltmeter.

1.8 Charging Rate Adjustment

Note: Charging rate adjustments may be necessary to compensate for locations of extreme AC line variation
or may be used to tailor the charger output for aging batteries.

The charging rate has been set at the factory; therefore, field adjustment should not be necessary.

If there appears to be a charging rate problem, refer to the troubleshooting chart, Section 4.

If it is necessary to either increase or decrease the charging rate, a rate adjustment terminal block is provided
on the top rear of the transformer mounting bracket.

Change only one step at a time and observe the effect on the battery before making a second change.

The charging rate is increased by moving to the next higher tap setting in Table 1-2.

The charging rate is decreased by moving to the next lower tap setting.

No adjustments should be made without consulting the factory.

SECTION 2 - OPERATION

2.1 046-0271 CONTROL

2.1.1 Operation
The 046-0271 control is used in high frequency or ferro-resonant taper chargers to provide fully
automatic battery charging. The control has a charging profile that handles standard flooded lead-acid
batteries. The charging profile, or algorithm, uniquely monitors the output current and voltage to optimally
charge the battery, based on battery manufacturer’s recommendations.
The control offers several safeguards to protect the battery. If a wrong voltage battery is connected, the
charger does not start and a Low-Battery-Voltage (F3) or High-Battery-Voltage (F4) message is displayed.
While charging, if the battery voltage exceeds a profile-specific cut-off value, the charge terminates with an
end on voltage message.
2.1.2 Normal Daily Charge
When no battery is connected, the LED indicators are off and the LCD display shows ‘0A 0.00VC’. With
the auto-start feature enabled, connecting a battery to the charger causes it to begin a charge cycle. The
charger first performs a self-diagnostic test to verify the control is working properly. During this time a lamp
test is performed causing all display segments and indicators to light. This allows the operator to observe any
defective segments or indicators. When the self-diagnostic is complete, the charge starts if no delay is set,
and the yellow ‘Charging’ indicator lights. The display shows the charging amps and battery volts per cell
along with a message to indicate the charger is in phase 1 of the charge cycle. If auto start is disabled, the
display shows ‘CHARGER OFF’. Press STOP to manually start the charge.
When the battery is 80% charged, the charger starts phase 2 of the charge cycle.
When a charge is finished, the charger automatically turns off. The yellow ‘Charging’ indicator goes out.
If cool down is enabled, the display shows the cool down time remaining. If cool down is disabled or the time
has elapsed, the display shows ‘0A x.xxVC’ along with a message indicating the battery is ready and the
green ‘Complete’ indicator lights.

Disconnecting the Battery

Warning: Risk of explosion. Do not disconnect the battery while the charger is running. Hydrogen gas produced
by the battery during charging can be ignited by arcing that occurs when the battery cable is disconnected.
If the battery must be disconnected before the end of the charge cycle, the charger should be turned off
first. Press STOP, and verify the yellow ‘Charging’ indicator goes out. The LCD display shows ‘CHARGER
OFF’. The battery may then be safely disconnected. If the green ‘Complete’ indicator is lit, the battery may be
disconnected at any time.

9
2.1.3 Equalize Charge
Over time batteries can develop inequalities in cell charge. This can lower the effective capacity of the
battery and shorten life. An equalizing charge re-balances the charge in the battery cells. Perform an equalize
charge if any of the following conditions exist:
1. On flooded batteries the specific gravity of any cell at the end of charge is 20 points less than the
average of all the cells.
2. The on-charge voltage of any cell at the end of charge is 20 millivolts less than the average of all the
cells.
3. The battery has been stored for 30 days.
The 046-0271 control can perform an equalize automatically if auto equalize is enabled. Normal
equalize consists of an additional 3 hour charge time at the end of a normal charge cycle. The 046-0271
control can also perform an equalize charge when requested manually. First connect the battery and allow the
charge to start normally. Then press =. The display shows ‘=’ on the left side and the charge time is extended
by 3 hours to allow the cells to equalize their charge.
The auto-equalize or manual equalize cycle can be cleared by pressing = while in the normal charge
cycle. The ‘=’ indication on the display turns off. The next auto equalize charge occurs after the set number of
charge cycles if auto equalize is enabled. If the set number of charge cycles have been completed, the
charger attempts to equalize after the next charge cycle and continues to attempt to equalize until an equalize
cycle has completed.
The default setting for automatic equalize is every 7 cycles. To change the number of charge cycles for
automatic equalize, refer to the programming section.

2.1.4 Delayed Start

The delayed-start feature allows the operator to delay starting the charge cycle. This might be desired to
reduce peak energy surcharges if the charger were ready to start during a peak energy period. The delay time
could be set to keep the charger from starting until after the peak period ends.
To view or change the delayed start setting, refer to the programming section.

2.1.5 Auto- Refresh Charge

The 046-0271 control can provide an auto-refresh charge as long as the battery remains connected
to the charger if enabled. If AC power is lost during the wait period, the control resumes from where it left off
after power is restored. During the auto-refresh charge, the amp-hours and charge time are added to the
original charge. The refresh charge consists of 30 minutes at the equalize current. To change the auto-
refresh settings, refer to the programming section.

10
 2.1.6 Viewing Charge Information
Additional charge information is available any time by pressing the INFO button. This information is
retained after the battery is disconnected until the next battery is connected. After 20 seconds the display
returns to the default display of amps and volts per cell. The following information can be viewed:

SECTION 2 – OPERATION (continued)
2.2 046-0272 CONTROL
2.2.1 DESCRIPTION
The 046-0272 charger control provides fully automatic battery charging in standard taper
ferro-resonant chargers, controlled ferro-resonant chargers, and HF chargers. The
control is powered from a 24VAC transformer that provides isolation from the AC service
line. The presence of a battery is detected by the control and causes a charge cycle to
begin automatically. The control has charging profiles that handle standard flooded,
gel-cell, and sealed lead-acid batteries, as well as other battery types such as nickel-
cadmium. Each charging profile, or algorithm, uniquely controls the output current and
voltage to optimally charge a particular type of battery, based on battery manufacturer’s
recommendations. The control can be set to start charging at a certain time of day. It can
be used with the I’m Cool System and the TOBi® Battery Management System.

The front panel has a 16 character LCD display which normally shows charging amps
and volts per cell along with a periodic message showing the charger state. This display
also presents messages if an abnormal charge indication is detected. A yellow ‘Charging’
indicator lights while the charger is charging. A green ‘Complete’ indicator lights when the
charge is complete. A red ‘Fault’ indicator lights if an abnormal charge indication is
detected.
2.2.2 PROGRAMMING
A minimum of five parameters must be programmed for proper operation: 1) the time of day and date,
2) the algorithm, which is determined by the type of battery being charged, 3) the amp-hour rating of
the battery which is obtained from the charger data plate, 4) the nominal battery voltage which is
obtained from the charger data plate, and 5) the current shunt rating which is imprinted on the side of
the current shunt located inside the charger. Gather this information before programming the control.
Press the SET key to enter the programming mode. The display shows ‘SET PARAMETER’. Then
another key or keys are pressed for the parameter to be programmed. The display then shows a brief
description of the parameter and its current value. The parameter is changed by entering a new value
using the numeric keys on the keypad. Data entry is from left to right. If more than four digits are
entered, the left-most digits scroll off the left end of the display. If an incorrect number is keyed in,
press 0 four times to scroll the bad number off the display and continue entering the correct value.
(Note that if no keys are pressed within about 8 seconds, the programming mode times-out and the
control returns to the normal ‘#A #.##VC’ display). Once the value is entered, press ENTER. If the
value entered is correct, the display shows ‘PARAMETER SAVED’ to confirm the value. (If an
incorrect value is entered the display shows ‘!! ERROR !!‘ and then returns to the normal
‘#A #.##VC’ display.)
Some of the programming parameters can be locked out to prevent a user from intentionally or
unintentionally changing the settings. When a parameter is locked, a lock appears on the display and
the value cannot be changed. Refer to the section on jumper settings for information on locking out
parameters.

2.2.2.1 Setting the Time-of-Day

Press SET, then CLOCK. The display shows ‘TIME OF DAY’ followed by ‘TD:’ and then the time-of-
day. Time is entered in 24 hour format (military time). If the actual time is 3:27 PM, it is entered as
15.27. Enter the correct local time using the numeric keys on the keypad. Press ENTER to save it.
2.2.2.2 Setting the Date
The date is set in 3 steps, first the month, then the day, then the year. Press SET, then 5, and then
CLOCK. The display shows ‘MONTH (1-12)’ followed by ‘MO:’ and the month, 1-12. Enter the month
using the numeric keys on the keypad and press ENTER to save it. If the month is accepted, the
display then shows ‘DAY (1-31)’ followed by ‘DY:’ and the day-of-month, 1-31. Enter the day using the
numeric keys on the keypad and press ENTER to save it. If the day is accepted, the display then
shows ‘YEAR (0-99)’ followed by ‘YR:’ and the year, 0-99. Enter the year using the numeric keys on
the keypad and press ENTER to save it.

16
2.2.2.3 Setting the Algorithm
Some algorithms have additional parameters that must be set for proper operation. Refer to
table 2 to determine which algorithm to use for your charger and battery type, as well as any
additional parameters that need to be set. If uncertain about which algorithm to use, contact
the factory before attempting to program the control.
Press SET, then 5, then START. The display shows ‘CHARGE ALGORITHM’ followed by ‘AL:’ and
the algorithm number. Enter the algorithm number using the numeric keys on the keypad and press
ENTER to save it.

2.2.3 OPTIONAL PARAMETERS

2.2.3.1 Setting the Cable Resistance
The cable resistance parameter is used to adjust the charger to compensate for extra long charging
cables. To set the parameter, connect a proper sized battery to the charger and allow the charge to
start and the current to stabilize. Press VOLTS twice to display the full battery voltage. Measure the
voltage at the battery terminals using a calibrated DC volt meter. If the readings differ, calculate the
resistance as (Vcharger-Vbattery)/current. To change the setting, press SET, then 3. The display
shows ‘CABLE RESISTANCE’ followed by ‘CR:’ and the resistance in mΩ (milliohms). Enter the new
value and press ENTER to save it. Repeat this process as needed until the voltage readings are the
same.

2.2.3.2 Setting Start Times and Peak Energy Block Out

The control has two different ways to delay the start of a charge cycle. They are the time of day start
and delayed start parameters. The time of day start setting allows the charger to start only at the
specified time regardless of when the battery is connected. The delayed start setting delays the start
of the charge the specified amount of time after the battery is connected (Note: If both parameters are
set, the control uses the time of day start). The control also has energy management settings which
allow a peak energy time to be blocked out. If a battery is connected and charging during this time,
the charger turns off and displays ‘ENERGY SAVE ON’. Once the period has ended, the charger
resumes from where it left off. All of these parameters are grouped together. To set these
parameters, press SET, then START. The display shows ‘TIME OF DAY STRT’ followed by ‘TS:’ and
the time of day start setting. Enter the desired time (99:99 to disable) and press ENTER. The display
shows ‘DELAY START TIME’ followed by ‘DS:’ and the delay time. Enter the desired delay time and
press ENTER. The display shows ‘ENERGY SAVE ON’ followed by ‘PS:’ and the peak period start
time. Enter the desired time of day for the start of the peak period (99:99 to disable) and press
ENTER. The display shows ‘ENERGY SAVE OFF’ followed by ‘EP:’ and the peak period end time.
Enter the desired time of day end of the peak period (99:99 to disable) and press ENTER to save it.
2.2.3.3 Setting the Automatic Watering
The control has the ability to automatically water the battery. A 24VAC solenoid/valve must be
installed (refer to charger schematic) and the battery must have a single point watering system
installed. To set the automatic watering, press SET, then 5, then 1. The display shows ‘WATERING
MODE’ followed by ‘WA:’ and the watering mode setting. Enter the desired mode (0: disable
watering, 1: water every charge cycle, 2: water after equalize only) and press ENTER to save it. If

17
watering is enabled, the display shows ‘WATERING CYCLES’ followed by ‘WC:’ and the number of
watering cycles. Enter the desired number of cycles (each cycle is 15 seconds on and 45 seconds
off) and press ENTER to save it.

2.2.3.4 Setting Automatic Equalize

The control has the ability to automatically equalize the battery based on the number of cycles or on a
specific day of the week. The equalize cycle can also be delayed a specified amount of time. To set
the automatic equalize parameters, press SET, then 5, then 3. The display shows ‘EQUALIZE
CYCLES’ followed by ‘EC:’ and the number of cycles before equalize occurs. Enter the desired
number of cycles (0 to disable) and press ENTER. The display shows ‘EQUALIZE DAY’ followed by
‘ED:’ and the equalize day. Enter the desired day (0 to disable, 1-7 for Sunday-Saturday) and press
ENTER. The display show ‘DELAYED EQUALIZE’ followed by ‘DE:’ and the equalize delay time.
Enter the desired delay time and press ENTER to save it.

2.2.3.5 Setting Cool Down Time

The control has the ability to set a cool down time to allow the battery to cool before it is used or to
display the elapsed time to determine the coolest battery. To set the cool down time, press SET, then
5, then 7. The display shows ‘COOL DOWN TIME’ followed by ‘CT:’ and the cool down time. Enter
the desired time and press ENTER. If a time is set, the display shows ‘COUNT DIRECTION’ followed
by ‘TU:’ and the direction. Enter the desired setting (0: count down, 1: count up) and press ENTER to
save it. If the direction is set to count down, the battery ready light does not come on until the cool
down time has elapsed. If the direction is set to count up, the battery ready light comes on when the
charge is complete and the elapsed time since the charge completed is displayed.

2.2.3.6 Setting Automatic Refresh

To set the automatic refresh interval, press SET, then 5, then 8. The display shows ‘REFRESH TIME’
followed by ‘AR:’ and the refresh interval time. Enter the desired interval for automatic refresh (00:00
to disable) and press ENTER. A refresh consists of 30 minutes of charging at the equalize current.

2.2.3.7 Setting Charger Alerts

To set the alert parameter, press SET, then 5, then 0. The display shows ‘ALERT ENABLE’ followed
by ‘AO:’ and the alert setting. Enter the desired setting (0:disable alerts, 1:enable alerts) and press
ENTER. The display shows ‘ALERT INTERVAL’ followed by ‘AI:’ and the alert interval in seconds.
Enter the desired setting and press ENTER. With alerts enabled, the control displays a message
describing the charger state at the set interval.

2.2.3.8 Setting Automatic Start Mode

To set the automatic start mode, press SET, then STOP. The display shows ‘AUTO START MODE’
followed by ‘AS:’ and the automatic start setting. Enter the desired setting (0: manual start, 1:auto
start, 2:auto start on AC) and press ENTER. If manual start is set, the charger never starts
automatically. When the battery is connected, the display shows ‘CHARGER OFF’. Press STOP to
manually start the charge. Also, in manual start mode the charger does not begin a refresh or
automatic equalize cycle once the charger has turned off. If auto start on AC is set, the charger
begins a new charge cycle whenever AC power is removed and restored to the charger. This is
useful in applications where the charger is permanently connected to the battery and a charge cycle
is initiated by plugging in the charger AC power cord.

2.2.4 Setting the Other Parameters

If the charger is part of an I’m Cool system or the TOBi® Battery Management System then the
charger identifier (ID) must be set. This and other additional parameters are programmed in a manner
similar to that above. Table 1 describes the parameters and key-strokes used for programming them.
When more than one parameter is in the same row of the table, the control automatically sequences
through the additional parameters.

2.2.7 OPERATION
If alert messages are turned on, periodically a message shows for about 2 seconds in the display. With no
battery connected, the control displays ‘0A 0.00VC’, and a ‘FERRO MAGNETICS’ alert is shown. When a
battery is connected, a lamp test is performed. The charge begins, the yellow CHARGING indicator lights and
the display shows ‘CHARGE PHASE 1’ periodically along with the charging amps and battery v/c. If equalize is
active, an ‘=’ appears on the left side of the display to indicate an equalizing charge.
When phase 1 is completed, the charger starts phase 2 of the charge cycle. The display shows ‘CHARGE
PHASE 2’ along with the charging amps and battery v/c. Depending on the charger and battery type, the
charger may utilize up to 4 phases to complete a charge.
During the equalize portion of the charge cycle the display shows ‘EQUALIZING’ periodically along with the
charging amps and battery v/c.
When a charge is finished, the charger automatically turns off. The display shows ‘BATTERY READY’ and the
green COMPLETE indicator lights. The battery may then be disconnected at any time.
2.2.7.1 EQUALIZE CHARGE
Over time batteries can develop inequalities in cell charge. This can lower the effective capacity of the battery
and shorten life. An equalizing charge re-balances the charge in the battery cells. Perform an equalize charge if
any of the following conditions exist:
1. On flooded batteries the specific gravity of any cell at the end of charge is 20 points less than the average
of all the cells.
2. The on-charge voltage of any cell at the end of charge is 20 millivolts less than the average of all the cells.
3. The battery has been stored for 30 days.
The control can perform an equalize automatically based on the number of charge cycles or on a specific day of
the week. Normal equalize consists of an additional 3 hour charge time at the end of a normal charge cycle.
The control is set at the factory to perform a normal equalize every 7 charging cycles for flooded lead-acid
batteries.
The control can also perform an equalize charge when requested manually. Press the = key. An ‘=’ appears on
the left side of the display indicating an equalize charge for the current charge. If no battery is connected, the
equalize occurs on the next charge cycle to allow the cells to equalize their charge.
The auto-equalize or manual equalize charge can be cleared by pressing the = key again. The next auto
equalize charge occurs after the programmed number of charge cycles.

23
2.2.7.2 THERMAL SENSOR OPERATION
The control has the ability to read the battery temperature with an optional thermal sensor. In order for the
sensor to function properly, it must be enabled in the control. This is accomplished by setting the ‘OK to charge
temp’ (OT) parameter to a non-zero value (see table 1). This value indicates the maximum temperature that
allows the charge to start. If the battery is above this temperature when it is connected, the control displays the
temperature and waits for the battery to cool down before starting the charge.
If the thermal sensor is enabled and is missing or damaged, the control displays an F11 indication when the
battery is connected.
The ‘Low charge temp’ (LT) parameter indicates the temperature at which the charge current is reduced to limit
the temperature rise of the battery. The current is reduced proportional to the amount the battery temperature
exceeds the limit.
The ‘No charge temp’ (NT) parameter indicates the temperature at which the charge is terminated. If this
temperature is reached during charge, the charger shuts down and displays an F2 indication.
Refer to the battery manufacturers recommendations before setting these parameters.
If the thermal sensor is enabled, the battery voltage milestones on charge (trip point, cutoff, etc.) are
compensated by 2.5mV/C per degree F (1.5mV/C per degree F for NiCad) above or below 77 degrees F. If the
temperature is below 77 degrees, the voltage is adjusted up and if the temperature is above 77 degrees, the
voltage is adjusted down.

2.2.7.3 TOBI® PI OPERATION

The control has the ability to communicate with a Tobi® PI battery module. In order for communication to occur,
it has to be enabled in the control. This is accomplished by setting the ‘BC’ parameter (see table 1).
Setting the BC parameter to 0 disables communication.
Setting the BC parameter to 1 enables normal communication.
炰‫ތ‬ While the battery is connected to the charger,
information is transferred between the charger and the Tobi® PI on the battery including the battery
temperature. In order for the charger to utilize the temperature, the temperature sensor must also be enabled.
Refer to the preceding section on thermal sensor operation.
Setting the BC parameter to 2 enables normal communication as well as algorithm upload. In addition to the
information transferred during normal mode, the charger also uploads and utilizes a charge algorithm from the
Tobi® PI on the battery. This can be useful if multiple battery types or AH sizes are used on the same charger.
Refer to the Tobi® PI manual for instructions on setting the charge algorithm. Note: If the communication
between the charger and Tobi® PI fails, the charger utilizes its own algorithm settings to charge the battery.

24
2.2.7.4 CHARGE INDICATIONS
The following indications are not necessarily a result of a charger problem. They are typically caused by
external problems such as AC line, poor battery conditions, connections, etc. If abnormal charge conditions are
detected, the charge is terminated, the red FAULT indicator lights and the display shows the code:

Note: F3 and F4 clear automatically if the battery voltage falls within acceptable limits. All indications
except F8, F9 and F10 can be cleared by disconnecting the battery. For F8, F9 and F10, correct the
condition that caused the indication and disconnect the battery to clear the indication.
CAUTION: If F8 indication is showing, and the charger is providing current to the battery, remove AC
power from the charger before disconnecting the battery.
2.2.7.5 F3 (LOW BATTERY) OVERRIDE
If battery voltage is below 1.6 volts per cell the charger does not start automatically. If this is due to an overly
discharged battery of the correct voltage, the F3 indication can be manually overridden by pressing STOP while
the F3 message (Low Battery) displays.

2.2.8 DISPLAYING ADDITIONAL CHARGE INFORMATION

The user can view many different parameters associated with a charge. By pressing an appropriate key,
information such as charger run time or amp-hours returned can be viewed. The display times out after about 2
seconds and returns to the default display which is usually amps and v/c.
2.2.8.1 Display Software Version
To display the software version number press VER. The display shows ‘SOFTWARE VERSION’ followed by
‘SW:’ and the software version number (e.g. 1.00).
2.2.8.2 Display Charging Current
In most applications charging current is normally displayed. If charging current is not already being displayed,
press AMPS to view. The display shows ‘CHARGER DC AMPS’ followed by ‘AA:’ and the charging current in
amps. If the charge has completed or no battery is connected, the display shows ‘CHARGE END AMPS’
followed by ‘EA:’ and the end current for the last charge cycle.
2.2.8.3 Display Volts Per Cell 7
In most applications volts per cell is normally displayed. If volts per cell is not already being displayed, press

SECTION 3 - OPTIONAL FEATURES

3.1 Fusible Door-Interlock Switch (JIC Switch)

The door interlock switch assembly connects the AC service to the charger’s input fuses for each AC line.
The switch is mechanically latched by the door so that it must be in the OFF position before the door can be
opened. Operation of the charger is identical to that of the standard model, except the charger cannot be
energized if the door is open.

3.2 Remote Control

The remote control option makes it possible to operate the charger at a point within 15 feet of the charger. It
includes a box equipped with the control option ordered, and either 15, 20, or 30 feet of jacketed control
harness. Operation is identical to that of a standard charger except that the control is not mounted on the
front of the charger.

3.3 Watering Valve

On chargers ordered with the 046-0272 control, an optional 24VAC watering solenoid can be ordered. The
valve will activate at the end of the charge cycle. It works in conjunction with an automatic watering system
that is supplied by others. Note: Watering valves have a one year part replacement warranty only.

3.4 Charger Stand

The charger stand is a metal frame that is designed to bolt the charger cabinet on top of it. It raises the
cabinet up to the operator’s level, rather than having the cabinet sitting on the floor.
