7 Troubleshooting
If you experience problems in the operation of your system, read through these
troubleshooting steps and perform those which are appropriate. This information may
help you to correct the following operational difficulties without calling your supplier or
sending your equipment in for repair:
l
Power-on
l
Stalled Display Following Power-on
l
Indicator Lock-up
l
Inaccurate Weight Readings
l
Alarm Light Malfunction
l
Measuring the Supply Battery Voltage
Instructions for sending an indicator in for repair are provided in the last section under
Service Repairs.
7.1 Power-On Failure
If your indicator doesn’t power-on, check the following possible problem sources in the
order given. Attempt to power-on after trying each of these four troubleshooting steps:
1. Check Battery Voltage. Required voltage is 10-18 volts DC negative ground. If
the voltage is between 8-10 volts, the indicator will display Lo-bAt. The indicator
will automatically turn off if the incoming voltage drops below 8 volts or rises
above 18 volts.
2. Disconnect and Check Power Cable Connector at the vehicle or AC to DC
converter, clean if necessary, and reconnect.
3. Replace Fuses. Sometimes, a bad fuse can be recognized by an obvious
break in the wire filament. However, such a break is not always observable,
and getting a successful power-on after changing a fuse is often the only way
of knowing that the fuse was indeed defective.
Make sure new fuses are the proper size and have a current rating of five
amperes. Using a fuse with too high a current rating can cause costly damage
to the indicator and will void your warranty. The same is true for substituting
wire, a nail, or any other object in place of a fuse.
Place nothing in the fuse connector except a proper fuse.
Change one fuse at a time (see instructions below). Try to power-on after
changing the first fuse; if unsuccessful, change the second fuse and try to
power on again. If changing the second fuse fails to allow successful power-
on, proceed to the next trouble shooting step.
