Safety during use
SAFETY DURING USE
Caution
Check system before use
Before you are going to use the Digi-Star weighing system you need to check the proper working
of the system by charging all weighing points with a known weight.
Digi-Star cannot be held responsible for deviations and problems arising from incorrect use of the
weighing indicator, incorrect calibration or settings. Furthermore Digi-Star cannot be held
responsible for deviations and problems arising from technical problems to the system.
During welding you need to remove the weighing bars to avoid damaging. If this is not possible,
you need to place the “ground” clip as close to the welding point as possible, in order to avoid that
current can flow through the weighing bars.
Digi-Star cannot be held responsible for problems arising from welding or charging of the battery.
Cleaning
Do not use running water (high pressure cleaners, hoses) to clean the indicator.
Charging battery and welding
During welding you need to remove the weighing bars to avoid damaging. If this is not possible,
you need to place the “ground” clip as close to the welding point as possible, in order to avoid that
current can flow through the weighing bars.
Digi-Star cannot be held responsible for problems arising from welding or charging of the battery.

TROUBLE SHOOTING
START
YES
Does the weighing indicator switch on?
Is the value displayed on
the weighing indicator
NO
YES
Put your weight on each
load cell.
Does the weighing indicator
respond to your weight?
YES
If the value is unstable or,
[± RANGE] flashes on the display,
disconnect the J-Box cable from the
weighing indicator.
Is the value still unstable?
YES
NO
Check all J-Box and
load cell cables for
loose contacts, cuts or
pinched, flat spots.
Are all values positive?
(negative values indicate
that the load cell concerned
is mounted upside down).
YES
The weighing indicator is
probably defective.
Test another weighing
indicator to be sure.
Note: Be aware of electrical
interference that might
affect the weighing
indicator, such as mobile
phones, CB radios, radio
towers, electrical motors
etc. Make sure load cell
cables are not attached to
hydraulic lines or
reservoirs.
NO
Bad connection
Check the power supply cable for
bad connections/contacts. Move the
power supply cable.
Bad battery
Replace the battery. A weak battery
may test good if it is tested with no
load on the battery.
Bad power supply cable
Make sure the red wire is connected
to the + (positive side) and the black
wire to the - (negative side).
When using a multimeter to check
the voltage, do you measure
between pin 1 (positive) and pin 2
(negative)?
The meter should show a value
between
10.5 and 14.5 Vdc. If using
a tractor power supply cable, the
black wire is connected to the + and
the white wire to the -.
Bad weighing indicator
Try another weighing indicator;
even a different model or setup
should function.
Does the weighing indicator
weigh you approx. the same
over all load cells?
Remove the cover from the J-Box.
NO
YES
The weighing indicator is probably
not set-up and calibrated correctly.
Check the decal on the bottom of
the weighing indicator. It shows the
type of load cells, for which the
weighing indicator was calibrated.
By pressing the ON key while the
weighing indicator is switched on,
the setup (SETUP) and calibration
number (CAL) will appear
successively on the display.
Ensure these numbers correspond
with the numbers on the decal on
the bottom of the weighing
indicator. Contact your dealer for
additional information.
Repair or replace
the J-Box.
Is there moisture
inside the J-Box?
NO
YES
Dry out the J-Box
(use a hairdryer).
Check cable strain reliefs
for tightness.
Do cables have drip loops?
Is lid gasket damaged?
Check for loose connections.
Watch your indicator display while
moving cables and wires and pressing
on the circuit board inside the J-Box.
You will see if there is a loose
connection or bad solder joint.
YES
Does the J-Box have a bad connection
or loose wires?
NO
See next page
D3895-GB Rev A
EZ2500 User' s manual

Trouble shooting
CONTINUED
Disconnect all wires of the load cell cables
from the terminals in the J-Box;
Leave the weighing indicator switched on
while disconnecting and reconnecting the
wires. It will not damage the load cells and
weighing indicator if wires are shorted during
this step. Is the value displayed on the
weighing indicator stable?
NO
Replace the J-Box;
Be aware of electrical interference that might
affect the weighing indicator, such as mobile
phones, CB radios, radio towers, electrical
motors etc.
Note the value displayed on the weighing
indicator with the load cell connected.
YES
Zero balance the weighing indicator.
(press and hold ZERO for 3 seconds).
The value 0 appears on the display of the
weighing indicator.
Note: Connect the load cells to the J-Box one at the time;
only one load cell connected at a time.
This will get a reading for each load cell. While performing this test,
watch for any other symptoms such as erratic/unstable readout,
flashing of [± RANGE] on the display, negative value, etc.
If the readout appears abnormal with any load cell connected, this
load cell is probably bad.
Reconnect one load cell to the terminals in the
J-Box; the displayed value of each load cell depends on the type of
load cell and the weight over the load cell.
Usually this value should be positive and stable.
Zero balance the weighing indicator and stand
or hang with your weight over the connected
load cell. Note the weight increase;
A weighing indicator with only one connected
load cell will give a too high readout.
Note: If the weighing indicator responded to your weight, the J-Box is
OK. If the weighing indicator did not respond, either the load cell or
the J-Box is bad. Try the other load cells.
If the weighing indicator still shows no response, the J-Box is bad.
Replace the J-Box.
Repeat previous steps for the other load cells.
Remember to note all readouts of these load
cells.
Disconnect the first load cell and zero balance the weighing indicator.
Connect the second load cell. Note the displayed value.
Zero balance the weighing indicator and stand or hang your weight
over the connected load cell. Note the weight increase.
Do not expect that all load cells
give the same readout at the moment you
connect them. Usually load cells give readout
values that vary by hundreds, even
thousands. Especially when there is more
weight on one load cell.
If you hang your weight over a connected load cell after zero
balancing the weighing indicator, the displayed value is probably three
or four times your weight. The readout values of your weight over
each load cell should be similar.
Bad load cells give an unstable readout, [± RANGE] flashes on the
display or the displayed value is lower or higher than three times the
average of the other load cells.
Any difference could be an indication of a bad load cell
or a structural problem.
