Unpacking Your Scale
Before unpacking your Doran scale, please read the instructions in this section.
Your new scale is a durable industrial product, but it is also a sensitive weighing
instrument. Normal care should be taken when handling and using this product.
Improper handling or abuse can damage the scale and result in costly repairs
that may not be covered by the warranty. If you notice any shipping damage,
notify the shipper immediately. Please observe the following precautions to
insure years of trouble free service from your new scale.
?
?
?
?
DO NOT drop the scale indicator or scale platform.
DO NOT immerse the scale indicator or platform.
DO NOT drop objects on the platform.
DO NOT pick up the scale platform by the "spider."
Carefully remove the scale from the shipping carton. Be sure to retain all
shipping materials in case the scale must be shipped elsewhere.
Setup and Installation
INSTALLATION:
Locate the desired position for the scale platform and indicator. The platform
location should be flat, level and free of any obstructions which might interfere
with the operation of the scale platform.
When installing your scale, make sure that an AC power outlet is close to the
scale and easily accessible.
Place the scale on a flat level surface free from any obstructions which might
interfere with the operation of the scale platform.
ELECTRICAL CONNECTIONS:
Prior to connecting your scale to power, check the serial number tag on the
indicator for the correct operating voltage. Verify that the power you connect the
scale to matches the rated voltage.
Be sure the AC power is not excessively noisy - this can occur if large inductive
loads, such as solenoids or motors, are on the same power line. The Model
4300 has a filtered power supply to reduce the effects of normal line noise, but
severe fluctuations may cause operation problems. If problems occur, noise
producing devices may have to be suppressed to minimize their effect.

Basic Weighing Operations:
1) Remove all items from the scale platter.
2) Press ZERO to zero the scale. The weight display should now read zero.
3) Place an item on scale platter and wait for the motion (MOT) indicator to turn
off, indicating a stable weight.
Power Up (AC Operation)
Plug in scale.
Power Up (Battery option only):
Press and release ZERO to turn on the scale.
Turn Off (Battery option only):
1) To turn off manually, press and hold the ZERO pushbutton for 2 seconds or
until the display shows "rel Pb." Then release, the ZERO pushbutton and the
indicator will turn off.
OR
2) The scale will turn off automatically at the end of the programmed power on
time delay when that mode is selected.

Indicators:
The Doran 4300 has a main display and eleven indicator lights. These indicators
provide the operator with information about the scale and the current weighing
operation. The main display is used to provide the operator with the current
weight. The units indicators, located on the right of the main display, show the
current measurement units.
? The Motion (MOT) located on the left side of the display, informs the operator
when the scale is in Motion.
? The Center of Zero (ZERO) indicators, located on the left side of the display,
informs the operator when the scale is at Zero.
? The negative (NEG) indicator informs the operator whether the weight display
is showing a negative weight.
? The low battery (BATT) indicator is avaliable when battery option is installed.
The BATT indicator informs the operator that a battery charge is required.
? Checkweigh information is provided by the OVER, ACCEPT and OVER lights.
ZERO:
The ZERO push button is used to zero the scale prior to making a reading. The
zero button can function over the full range of the scale. To zero the scale, wait
until the scale is stable and press the ZERO button. The scale will zero
immediately. The 4300 will not zero if the scale is in motion. The 4300 is
equipped with an optional Zero on Demand feature which holds zero requests
until motion stops. This option may be activated during the scale setup
procedure. Refer to your dealer or Instruction manual for details.
UNITS :
The UNITS button permits the operator to change the scale units by pressing a
button. After pressing UNITS, the units indicator will immediately display the
current weighing unit. The UNITS button has several configuration parameters
which can disable the UNITS button or limit the display units available. Refer to
your dealer or Instruction manual for details.
PRINT:
The PRINT button permits the operator to print the current weight by pressing a
button. Like the ZERO button, the user must wait for motion to stop before
pressing the PRINT button. The current weight will then be transmitted to the
printer. When the data is transmitted, the left most display digit will momentarily
display a "r" to confirm data transmission. The 4300 has a "Print on Demand"
feature which stores a PRINT request until the scale is stable. Once stable, the
scale transmits the current weight to the printer. The 4300 also has several
automatic print options which may be used to simplify printer operation. Refer to
your dealer or Instruction manual for details.
5
OVER / UNDER:
The OVER and UNDER pushbuttons are used to enter the weight values needed
for checkweighing applications. In their simplest configuration, these buttons will
enter the check weight by pressing either the OVER or UNDER button. When in
this mode, the current weight is entered as the checkweighing limit.
The default entry mode uses the OVER and UNDER buttons to take the current
weight and scroll it up or down (arrows on the button indicate the scroll direction)
until the desired check weight is reached. Once the desired value is reached,
pressing ZERO (ENTER) will enter the desired value in the scale. The 4300 also
offers five band check weighing feature. Refer to your dealer or Instruction
manual for details.
Accumulator and Counter (Hidden pushbutton):
Press the Capacity Label / Hidden pushbutton to enter the accumulator / count
recall mode. The display will show "Accunn" followed by the accumulated weight,
then "Countr" follow by the counter value. The display will continue to repeat this
message until a key is pressed. The accumulator / counter recall mode will
display the accumulator value in the units currently selected in the weigh mode.
The accumulator and counter is incremented once every time a manual or
automatic accumulation occurs. When the weight has been added to the
accumulator and the counter has been incremented, the left most display digit
will momentarily display a "o" to confirm operation. The maximum value that can
be shown for the accumulator and counter is 6 digits or 999999. When the
maximum value is reached, the accumulator or counter will rollover starting at a
zero value.
Press the UNITS pushbutton to exit the accumulator / counter recall mode
without changing their values.
Press the ZERO pushbutton, while in the accumulator / counter recall mode to
clear the accumulator and counter values. The display will show "Clr Ac" and
exit from the recall mode.
Press the PRINT pushbutton, while in accumulator recall mode, to transmit the
accumulator and counter values through the RS232 port or optional
communication port. Label buffer 4 contains the print string formatting for the
accumulated weight and counter value. Refer to your dealer or Instruction
manual for details.
Note: Changing the current display units will clear both the accumulator and
counter values while in the weigh mode. Only Available in non Legal for Trade
applications.

Battery Operation: (Optional)
The 4300 with battery option is internally equipped with a self-contained
rechargeable, sealed, gelled-electrolyte battery and charging circuit. The
indicator is designed to run continuously for 60 hours on a fully charged battery
with one 350 ohm load cell.
The built-in charging circuit will fully charge the battery in approximately four
hours. To charge the battery, simply plug the line cord into a standard 115V
(230V optional) wall outlet.
The scale can be used while recharging the battery. A full recharge takes place
in four hours, whether the scale is on or off. The scale can be used with the AC
charger cord plugged in on a continuous basis.
If an AC power failure occurs, the scale's battery takes over immediately to
provide uninterrupted scale operation for up to 60 hours.
Low Battery Indication (Battery option only):
The BATT indicator indicates that the battery is in need of recharging. Once the
BATT indicator turns on, there will be approximately one more hour of battery life
before the scale shuts down. When the battery is too low to run the scale, the
4300 automatically turns off and will not operate again until the battery is
recharged. The scale remains accurate and useable even with the "BATT" on.
Warning: Permanent damage to battery could occur if the battery is not fully
recharged after the BATT indicator has been on.
Note: Battery life can vary depending on the following:
1. The number of load cells connected to the indicator.
2. The operating temperature.
3. Whether or not the battery is fully charged after each low battery
event.
4. Any installed communications, output or beeper options.

Common Problems and Solutions
Problem:
Weight reading will not
repeat or scale does not
return to zero when weight
is removed.
Scale weighing range is
limited, and will not indicate
full capacity or go into
overload.
What to Do or Check:
Make sure that there is nothing caught in the platform under
or around the load cell or spider interfering with its
movement.
Make sure that there is nothing caught in the platform under
or around the load cell or spider which would interfere with
their movement.
Make sure all four overload stops are properly set. Take the
platter off the platform, invert it and place it back on the
spider. With 1/2 of the scale's capacity in test weights
concentrated over a corner of the platform, there should be
approximately 1/32" of clearance between the stop and the
bottom of the spider. Check all four corners then recalibrate
the scale. If the problem persists, it is possible that the
scale is being shock-loaded causing the load cell to be
shifted.
Scale will not come to zero Make sure that the scale is stable ("MOT" annunciator is
when the ZERO button is
off) when ZERO is pressed. If excessive motion is a
pressed.
problem, then it may be necessary to activate the latching
zero feature (2Od) or lengthen the filter time (Av C32).
There may be a problem with the touch-panel or main
board.
Weight readings don't seem Make sure that there is nothing caught in the platform under
