Chapter 9: Troubleshooting
Verify if there is not a short-circuit on the terminal or on the load cell
If the problem persists, contact AP/Cumberland or GSI Electronics
Issues with inputs readings
(LC(x) – SIG- and LC(x) –
EXC-) Verify if the load cell wiring is correct according to the wiring diagrams
Verify if the load cell is connected at the right terminal
Verify if the LED “REF. OC. FAULT” on PCB-415 inside the EDGE Bin Scale is
activated, there is an overload at the output LC(x) - SIG+
Verify if the load cell link has been severed.
Verify if the load cell link length is below 50 feet (15m) with the recommended
gage
Verify if the load cell is good: The voltage must be higher than 0,3V
If the problem persists, contact AP/Cumberland or GSI Electronics
The weight reading is not
accurate (too high or too low)
Alarms or troubles messages
like:
Load cells reads a significant
higher / lower weight than
other load cells on the tank.
See “Issues with inputs readings”
The bulk feed tank has been calibrated with the load cell sensitivity not set prop-
erly. Re-calibrate this Bulk feed tank with proper load cell sensitivity.
Verify if there is a load cell on each bulk feed tank leg?
Verify if the load cells are free of debris, ice, etc.
Verify if the load cells are damaged. If so, replace the damaged load cell.
Verify if the load cell mounting brackets are fastened securely .
If the problem persists, contact AP/Cumberland or GSI Electronics
The weight reading never
changes See “Issues with inputs readings”
Calibration was not done properly. Re-calibrate.
Verify if the load cells are free of debris, ice, etc.
Verify if the load cell mounting brackets are securely fastened.
Verify for damaged or defective load cells . If so, replace.
If the problem persists, contact AP/Cumberland or GSI Electronics
The weight reading is affected
by thunder storm The grounding of the bulk feed tank legs is incorrect. Refer to the mounting
drawing to know more about the ground strap installation.
Trouble message: A load cell
reached maximum weight
(meaning: load cell is
overloaded). The bulk feed tank has been overfilled. Remove feed from tank.
Verify that the load cell capacity setting match the installed load cells.
The load cell capacity is too small for the size of the bulk feed tank. Replace
with higher capacity load cells.
The feed weight is not distributed evenly in the bulk feed tank.
Verify if the load cell is free of debris, ice, etc.
Verify if the load cell mounting brackets are securely fastened.
Verify if the load cell is damaged. If so, replace the damaged load cell.
Do the verification at the problem “Issues with inputs readings”
If the problem persists, contact AP/Cumberland or GSI Electronics
Trouble message: The tank
weight is [value] of maximum.
Check tank level Too much feed in the tank (Did you receive a feed load recently?)
Verify if the load cells are free of debris, ice, etc.
