1 INTRODUCTION

The E302 indicator provides an accurate, fast and versatile general

purpose indicator with parts counting, percent weighing and check-
weighing functions.

The E302 has LEDs to indicate when a weight is below the low limit,
between the limits or above the high limit next to the display. These
can work in conjunction with an audible alarm for check weighing as
well as LCD showing LO, OK and HI.

The E302 is supplied with a RS-232 bi-directional interface and real

time clock (RTC).

The E302 has a sealed keypad with colour coded membrane switches
and a large easy to read liquid crystal type display (LCD) supplied with a
backlight.

Includes automatic zero tracking, semi-automatic & pre-set tare,

accumulation facility that allows the weight to be stored and recalled as
an accumulated total.

OIML Approved models, E302 -M, do not allow pounds units, have
calibration controlled by jumpers or passcodes and other limitations as
noted in the manual.

3 INSTALLATION
3.1 UNPACKING
This indicator must be connected to a load cell platform and calibrated as necessary
to match the platform and user requirements. See Section 15 for set-up
information.

The users application and the technical specifications of the platform or load cell will
determine the necessary configuration.

3.2 LOCATING
The scales should not be placed in a location that will
reduce the accuracy.

Avoid extremes of temperature. Do not place in direct

sunlight or near air conditioning vents.

Avoid unsuitable tables. The table or floor must be rigid

and not vibrate.

Avoid unstable power sources. Do not use near large

users of electricity such as welding equipment or large
motors.

Do not place near vibrating machinery.

Avoid high humidity that might cause condensation.

Avoid direct contact with water. Do not spray or
immerse the scales in water.

Avoid air movement such as from fans or opening doors.

Do not place near open windows or air-conditioning
vents.

Keep the scales clean. Do not stack material on the

scales when they are not in use.

7
 3.3 CONNECTION
This indicator must be connected to a load cell platform and calibrated as necessary
to match the platform and user requirements.

The E302 has a connector configured for a 6 wire load cell. Connect the load
cells/platform to the indicator as shown below. The cable length should be as short
as possible, using a large size wire to minimise errors due to resistance in the leads.

E302-M model must use the 6 wire connection and has certain limitations for wire
size and length. Refer to the Approval Test Certificate for details.

8
Figure 1A shows the connections to a 6 wire load cell. Figure 1B shows a preferred
method to attach a 4 wire load cell, using a 6 conductor cable to go from the
indicator to the platform or load cell where it connects to the 4 wires from the load
cells. The Excitation and sense wires are connected together near the load cell.

For less exacting applications you can connect the excitation to the sense at the
connector.

5.1 SYMBOLS AND INDICATORS

The LCD has unique symbols to indicate the following:

0 The display is at Zero

The scale is Stable

Net Net weight- The scale has been tared

kg / lb Symbols shown for the units

Capacity Tracker- A bar graph indicating the proportion of the

scale capacity being used by the weight on the pan

pcs The scale is in Parts counting mode

HI, OK, LO The scale is in Check weighing mode

: The colons “:” are used to separate pounds from ounces and
for the real time clock.

11
Next to the LCD are a number of LED’s that show when the weight is below, within
or over the limits during check weighing.

Weight LED LCD

below the low limit Amber LO

Within the limits Green OK

Above the high limit Red HI

NOTE: The LED’s can be set by the user to off, bar, spot or segment mode. See “F3
LED” in section 13.1

The LED can be set to display as a bar, increasing from Low to OK to High, a single
spot increasing from Low, OK to High, or as a single bar that changes colour as the
weight progresses from Low to OK to High.

6 CALIBRATION COUNTER FOR APPROVED INDICATORS

With approved (E302-M Model) indicators we have the ability to control access to
the calibration or metrology parameters using a passcode to limit access. The
requirements for doing this stipulate the code should be apparent and recorded in a
suitable location on the indicator.

In this way if the record of the Calibration or Parameter counters do not agree with
recorded settings the responsible person inspecting the indicator can take
appropriate action.

12
The Counters are incremented any time the calibration section or the Factory
parameters section have been modified.

At power on, the display will show the current software revision number followed
by the message of the Calibration Count “[AL[nt” then a number i.e. “123”. The
number from the counter memory. Then the Parameter Counter message of
“PAr[nt” and probably a different number, i.e. “234”. The counters cannot be
reset to 0, they will increment until the display can no longer hold the values. (1 to
999999). It is expected we will never have more than 1 million calibrations in the
life of the machine.

Each display is held for 1-2 seconds.

The indicator will then continue to do the display test and go to normal weighing.

If during the time the counting displays are shown, the user presses the [Tare] key,
the user will be given a message to enter the passcode necessary to calibrate the
indicator, “P - - - - “ Enter the code “P0000” to Enter calibration or “P1000” to
enter the parameters, followed by pressing the [Tare] key.

The Calibration access will allow user calibration (See section 15.1) and the
parameter code will allow access to the following parameters. (see section 15.2).

“F4 Int” Initial Zero Range

“F5 rEZ” Re-Zero range

“F6 SCS” Successive Tare Enable

“F7 Cnt” Display ADC counts

“F8 Zem” Zero Mode

“F9 Lvd” Low voltage detection

Other parameters must be changed using the service parameters as described in

section 15.2

13
7 BATTERY
The indicators can be operated from the rechargeable battery, if
desired. The battery life is determined by the number and impendence
of the load cells connected. With a single load cell and backlight
disabled the life is approximately 70 hours before needing to be
recharged.

When the battery needs charging a symbol on the display will turn on.
The battery should be charged when the symbol is on. The indicator will
still operate for a period of time after which it will automatically switch
off to protect the battery.

To charge the battery, simply plug into the mains power supply. The
indicator does not need to be turned on.

The battery should be charged for 12 hours for full capacity.

To the right of the display is a LED to indicate the status of battery

charging. When the indicator is plugged into the mains power the
internal battery will be charged. If the LED is green the battery is being
charged. If it is red it is nearly discharged and yellow indicates the
battery is increasing the charge level. Continue to charge overnight for
a complete re-charge.

8 BACKLIGHT
The backlight for the LCD can be set by the user to always off, always on or
automatic (on only when the indicator is in use or a key is pressed). See setting of
the parameter “S2 bL” in section 13.3.

9 AUTO POWER OFF

The auto power off can be set by the user to disable the feature or to a pre-set time
interval. See setting of the parameter “S3 AoF “ in section 13.3.

14
10 OPERATION
10.1 ZEROING

You can press the [Zero] key at any time to set the zero point from
which all other weighing and counting is measured. This will usually be
necessary when the platform is empty. When the zero point is obtained
the display will show the zero indicator.

The indicator has an automatic re-zeroing function to account for minor

drifting or accumulation of material on a connected platform. However
you may need to press [Zero] to re-zero the indicator if small amount of
weight is still shown when the platform is empty.

10.2 TARING
10.2.1 MANUAL TARE
Zero the indicator by pressing [Zero]. The zero indicator will be on.
Place a container on the pan and its weight will be displayed.
Press [Tare] when the reading is stable. The weight that was displayed
is stored as the tare value and it is subtracted from the display, leaving
zero on the display. The stable and Net indicator will be on.

As a product is added only the weight of the product will be shown. The
indicator could be tared a second time if another type of product was to
be added to the first one. Again only the weight that is added after
taring will be displayed.

15
 NOTE:

When the container is removed a negative value will be shown. If the

indicator was tared just before removing the container, this value is the gross
weight of the container plus all products which were removed. The zero
indicator will also be on as the platform is back to the same condition it was
when [Zero] was pressed last.

If the value to be tared is very large the scale may not allow you to tare the value as
the negative value will not fit on the display area. In this case the scale will beep
twice when the [Tare] key is pressed and then return to normal weighing without
setting tare.

Press [Tare] or [Zero] to remove the tare value and display zero. The Net indicator
will disappear.

10.2.2 PRESET TARE (NOT AVAILABLE ON E302-M APPROVED

INDICATORS)

When the indicator is at zero with no weight on the platform it is possible to enter a
preset tare.

Zero the indicator by pressing [Zero]. The zero indicator will be on.

Enter a value using the numeric keys.

Press [Tare] to tare the indicator. The value that was entered is stored
as the tare value and it is subtracted from the display, leaving a
negative number on the display.

16
10.3 WEIGHING

To determine the weight of a sample, first tare an empty container if used,

then place the sample in the container. The display will show the weight and
the unit of weight currently in use.

To change the weighing unit press the [Unit] key. The only alternative
weighing unit is pounds. This can be enabled by the user in the parameters
section. See section 13.3.

10.4 PARTS COUNTING

The indicator can be used to count parts based on the average weight of a
sample weighed. When more parts are added the total number of parts are
displayed.

If a container is to be used, place this container on the platform before

entering parts counting and press [Tare].

Press [Cnt] to enter the Parts Counting mode. The display will show the
last sample size used. For example, “10 Pcs”.

17
Either place 10 parts on the platform for determining the average piece
weight or use a different number of parts. For example, place 20 parts on
the platform, press [CE] to clear the last values and then enter the value
20 using the numeric keypad.

Press [Cnt] to weigh the samples and determine an average piece

weight.

If the parts are too light to measure accurately, the count may become
faulty. It is suggested that the samples to be weighed should each weigh
more than the resolution of the indicator.

After the sample has been weighed the indicator will count any other
parts added by applying the average piece weight to the weight of the
parts to be counted.

The [Tare] key works normally during this time, so it is possible to tare
the display with a container on the platform or to enter a preset tare
value as described in section 10.2.2.

During parts counting the display can be changed to show the net

18
weight, unit weight and number of parts by each time pressing the
[Func] key.

19
To count a different sample quantity, press the [Count] key. The display
will show the last used sample size. Either use this sample size with a
different part or enter a new sample size as above.

To return to weighing, press [Unit] when “XX pcs” is displayed.

20
10.5 CHECK-WEIGHING

Check-weighing is a procedure to display an indicator or sound an alarm when

the weight on the platform meets or exceeds the values stored in the
memory. The memory holds values for a high limit and a low limit. Either or
both the limits can be set by the user.

NOTE:

1. The alarm and the LED bargraph can each be set to OFF (See section 13.1).
The LCD display will indicate whenever the weight is within or exceeds the
limits by showing ‘OK’, ‘HI’ or ‘LO’.

Mass on the platform is above the high limit

Mass is between the limits

Mass is below the low limit

2. The limits can be locked by the manager. A Limit Password must be used to
change the limits or recall other limits from memory.

3. If Limit Password is enabled then enter the password which will allow you
to change the limits or the operation of the beeper or bargraph.

21
10.5.1 SETTING UP WHILE WEIGHING

Press the [Low Limit] key. It will show the current low limit. The “LO”
symbol will appear on the display.

Press the [CE] key to clear the old value and then enter the new low
limit using the numeric keys. The decimal point is fixed at the position
that is used for the current weighing unit. When the desired value is
shown press [Tare] to accept the value. If you want to reset the value to
zero, press [CE] to clear the value.

The limits are displayed in the weighing unit in use.

To set the high limit press [High Limit], the display will show the high
limit, the “HI” symbol will be on to the left side of the display. Set the
high limit in the same way the low limit was set.

Pressing the [Tare] key to enter the value will return the indicator to
weighing, with the Check-weighing function enabled.

22
 10.5.2 SETTING UP WHILE PARTS COUNTING OR % WEIGHING

During parts counting and percent weighing the limits are set in the same way as
above. The limits are displayed in pcs or %.

See Section 10.4 for the description of parts counting and Section 10.7 for percent
weighing.

NOTE:

1. The weight must be greater than 20 scale divisions for the check-
weighing to operate.

2. To disable the check weighing function, enter zero into both the limits as
described above. When the current limits are shown, press [CE] to clear
the settings, then press [Tare] to store the zero values.

10.6 LIMITS STORING AND RECALLING

The indicator can store up to 10 sets of high and low limits in memory along with the
weighing units in use (including pcs for parts counting and % for percent weighing)
as well as settings for the beeper and bar graph.

During Check weighing the current limits can be stored or previously stored units
can be recalled.

23
Press the [Lim] key. If you are already in
the check weighing mode the display will ask
if you wish to store the current limits by
showing “StOrE” or recall another set of limits
by showing “rECALL”. The [Lim] key can be
used to toggle between “StOrE” and “rECALL”.

If you want to store the limits, when “StOrE”

is displayed press the [Tare] key. The display
shows “St ”. Enter a number corresponding
to the desired memory location (0 to 9). “St
X” will be displayed for 2 seconds indicating
the location X where the current limits,
weighing units and settings for the beeper
and bar graph are stored. The indicator will
continue to work with the current settings as
active.

If you wish to recall any of the pre-stored

limits, press [Tare] when “rECALL” is
displayed. The display shows “rEC ”. Enter the
number corresponding to the desired
memory location (0 to 9) to be recalled. “rEC
X” will be displayed for 2 seconds indicating
the values stored in the location “X” is being
recalled. The indicator will change to the
recalled limits, weighing units and settings
for the beeper and bar graph.

24
NOTE:

1. If the recalled limit is for parts counting, the display will show the last sample
value used, ready for a new sample to be counted.

2. If the recalled unit is a percent weighing limit, the display will show the last
sample value used, ready for a new sample to be weighed.

3. If the memory location was empty the indicator will return to weighing.

10.7 PERCENT WEIGHING

The indicator can be set to perform percent weighing. See Section 13.1.

The indicator will use a mass on the platform as the 100% reference weight. If the
platform is empty (or the indicator is tared) then the user can input a reference
weight using the keypad.

If using a reference weight (or object) as your 100% reference, add the weight
to the to the platform.

Press [Func]. The first option is “FUnC 1”, press the [Func] key 3 more times to
display “FUnC 4”.

Press the [Tare] key. “F4 PCt” will be displayed.

25
Press [Tare] again to enter percent weighing. The indicator will set the sample
mass on the platform as 100% reference weight.

NOTE: If there is no reference weight on the pan and percent weighing

function is entered, pressing [Tare] again will return the indicator to normal
weighing.

Remove the sample weight. Then any other weight placed on the platform
will be displayed as a percentage of the original sample. For example, if
3500g is placed on the platform and percent weighing is selected, the display
will show 100.00%. Remove the 3500g weight and place a 3000g weight. The
display will show 85.7% as 3000g is 85.7% of 3500g.

The number of decimal points will depend on the weight used. A smaller
weight will show only “100%” while a larger weight might show “100.00%”.

If the indicator was showing zero weight before entering this function, then
the user must manually enter the weight to be set as 100%. When “F4 PCT” is
displayed, enter the weight to be used for the 100% reference, then press
[Tare] to accept the reference weight. The display will show “0.00 %”.

26
 If the indicator shows “x x . x x %”, which is the last weight used as a reference,
press [CE] to clear and use the numeric keypad to enter a new value. Press
[Tare] to accept the new reference weight.

The weight entered must be greater than 50 scale divisions.

Press [Unit] to return to normal weighing.

NOTE:

The display may jump by large numbers unexpectedly if small weights are used to
set as 100% reference. The indicator checks if the weight is too small and will show
Error 7.

27
 10.8 ANIMAL (DYNAMIC) WEIGHING
The indicator can be set to animal (dynamic) weighing for weighing any items that
are unstable or may move. See Section 13.4.

The indicator uses a special filter to minimise the effects of any movement on the
platform.

Press [Func]. The first option is “FUnC 1”, press the [Func] key 3 more times to
display “Func 4”.

Press the [Tare] key. “F4 PCt” will be displayed. Press the [Func] key to
advance to the second function, “F4 AnL”, Animal weighing.

Press [Tare] to enter the animal weighing function.

To use the Animal Weighing function it is necessary to set the amount of

filtering required for the animals to be weighed. More active animals will
require a higher level of filtering to give a stable result. The display will show
“Filt x” where x is a value from 1 to 5. The higher the value the greater the
amount of filter will be. To increment the value shown press the [Func] key
then press the [Tare] key to accept it.

The display will flash “Ani “ 2 times then show the current weight, 0.00. The
indicator is now ready to weigh.

28
 10.8.1 ANIMAL WEIGHING PROCEDURE

With the platform empty the display will show zero weight.. Place containers
or blankets onto the platform and press the [Tare] key to zero the display.
The indicator may go into the animal weighing procedure when the items are
placed on the platform but will return to showing zero when the [Tare] key is

Place the animal to be weighed on the platform.

When a stable reading is found, the display will show this value, and the
display will be locked until the [Unit] key is pressed. The display will show the
“Hold” symbol while the display is locked. Remove the animal, the display will
hold the weight value.

Press the [Unit] key to unlock the display. The display will flash “Ani” twice,
and be ready for the next animal.

To weigh a second animal press the [Tare] key if necessary to zero the display,
and place the next animal on the platform. It is also possible to simply place
the next animal on the scale without clearing the last value first. The indicator
will detect the new weight and hold it as before.

The indicator will remain in the animal weighing mode until the [Zero] key is
pressed. Then it will return to normal weighing.

29
 10.9 ACCUMULATED TOTAL

The indicator can be set to accumulate when a weight is added to the platform
automatically or manually by pressing [Print]. See Section 13.2.

NOTE:

1. The accumulation function is available only during weighing. It is disabled

during parts counting or percent weighing.

2. The accumulated weights will be stored in either kg or lb, depending upon

the weighing unit in use.

3. If at any time the weighing units are changed, the accumulated data will be
lost.

10.9.1 MANUAL ACCUMULATION

When the indicator is set to manual accumulation, the weight displayed will be
stored in the memory when the [Print] key is pressed and the weight is stable.

Remove the weight and press [Print] when the indicator is at zero. The
display will show "ACC 1" and then the weight in memory for 2 seconds
before returning to normal. The weight can be output to a printer or PC
using the RS-232 interface.

30
When the indicator is at zero place a second weight on the platform.
When stable press [Print] to accumulate the weight. The display will
show "ACC 2" for 2 seconds and then show the new total.

Continue until all weights have been added. This can continue for up to
99 entries until the capacity of display is exceeded.

To view the total in memory press the [Print] key when the indicator is
at zero. The display will show the total number of accumulation "ACC
xx" and the total weight before returning to zero.

To print the total, press [Print] to recall and then immediately press
[Print] the second time to print the results.

To erase the memory, press [Print] to view the total and then
immediately press [CE] to clear the memory.

31
 10.9.2 AUTOMATIC ACCUMULATION

When the indicator has been set to Automatic Accumulation the value is stored in
memory automatically.

Place a weight on the platform. The beeper will sound when the display
is stable indicating the value is accepted. Remove the weight.

 11.1 INPUT COMMANDS FORMAT

The indicator can be controlled with the following commands. Press the [Enter] key
of the PC after each command.

T<cr><lf> Tares the indicator to display the net weight. This is the same as
pressing [Tare].

Z<cr><lf> Sets the zero point for all subsequent weighing. The display shows
zero.

39
12 CALIBRATION
The E302 indicator can be calibrated using kilogram weights or using
pounds weights, depending on the weighing unit selected at the time of
calibration.

To start the calibration, either get into the calibration section through
the Indicator Settings (“FUnC 3”- see Section 13.3) or turn the indicator
off and switch on again and then press [Tare] during the self-test. Enter
code number 0000 and press [Tare]. This will take you directly to the
calibration section.

The display will show "UnLoAd"

Remove all weight from the platform and then press the [Tare] key
when the display is stable. After the Zero point is set, the display will
show “Ld xx”. Place the suggested calibration mass on the platform. It is
best to use a weight close to the full capacity of the indicator. If the
mass is different from the displayed value, enter the value of the mass
in whole numbers. The kg or the lb symbol will be on to show the active
unit.

Press the [Tare] key when the stable indicator is on.

The indicator will calibrate to the mass. When complete, it will display
“PASS” and then either display “S8 CAL” (if entered the calibration
section through the Indicator Settings as per section 13.3) or return to
normal weighing (if entered directly). Remove the calibration mass.

If an error message “FAIL H” or “FAIL L” is shown, re-check the calibration

and repeat. If the error cannot be corrected contact your supplier.
