Troubleshooting
a. Disconnect all cables on bottom panel of Indicator except for power cable.
Do disconnect Weigh Bar® cables, and, if present, alarm cable remote
display cable, etc.
b. Now try powering-on. If this is not successful, your problem is in the indicator
and you should contact your supplier.
c. If you are able to power-on with only the power cable connected, your
problem is probably not in the indicator; continue troubleshooting.
d. With power still on, plug in cables, one at a time — Weigh Bar® cables first,
then alarm cable, then printer/remote display cable, etc. — until plugging in
one of the cables causes the indicator to shut off. That cable is the bad one
and needs to be repaired or replaced.
12.2 Indicator Over/Under Capacity
An over-ranged indicator is represented by upper dashes or lower dashes.
1. Test the Weigh Bar®cables to isolate the source of the over-range problem, as
follows:
a. Disconnect all Weigh Bars®.
b. Try to zero the indicator by pressing GROSS and clear.
l If you are unable to zero the indicator with the Weigh Bars® disconnected,
the problem is in the indicator and you should contact your supplier.
l If you are able to zero your indicator with the Weigh Bars® disconnected,
then the problem is probably in the Weigh Bars® and you should continue
troubleshooting.
2. Reconnect all Weigh Bars®. You will see upper or lower dashes displayed
again.
3. If your Weigh Bar®connectors have the four-pin configuration, disconnect one
Weigh Bar® and connect an adapter plug in its place.
If your Weigh Bar® connectors have the five-pin configuration, disconnect one
Weigh Bar®. No adapter plug is necessary.
4. Try to zero the indicator.
Repeat with each Weigh Bar
®
cable, making sure each time that all cables are
connected except the one you removed (for five-pin connector) or replaced
with an adapter plug (for four-pin connector).
A defective Weigh Bar
®
may be easily recognized with this method — when a
defective bar is replaced with an adapter plug (for four-pin connector), or
removed (for five-pin connector), the indicator will zero properly.
