Troubleshooting
Problem Solution
The EDGE Bird
Scale does not
communicate Verify if the controller is powered up
Verify if there are activities on the bus communication by looking at the activities of the
LEDs: LED4, LED5, LED6, LED7 on the PCB-415
Verify if the network link is installed correctly: Terminal A from EDGE Bird Scale to the
controller terminal A, Terminal B from EDGE Bird Scale to the controller terminal B
Verify if the network communication is installed in daisy chain.
Verify if your end of line (EOL) are set correctly on your network
Verify if the network link is not cut: wire is cut or the protections are activated
Verify if there is not a short-circuit on the network link between terminal A and B
Verify if the network link length is below 4000 feet (1200m) with the recommended gage.
Measure the voltage between the terminal 24V and GND. The voltage must be at least
16V
If the problem persists, contact your AP/Cumberland or GSI Electronics
The EDGE Bird
Scale does not
power up Verify if the LED "5V" is activated on the PCB-415
Measure the voltage between the terminal 24V and GND. The voltage must be at least
16V
Verify if the power link is installed correctly: Terminal 24V from EDGE Bird Scale to the
controller terminal 24V, Terminal GND from EDGE Bird Scale to the controller terminal
GND
Verify if the power link is not cut: wire is cut
Verify if the power link length is below 300 feet (1000m) with the recommended gage.
If the problem persists, contact your AP/Cumberland or GSI Electronics
Issues with the volt-
age output to power
the load cell (LC(x) -
EXC+ and LC(x) –
EXC-) Verify if the load cell wiring is conformed 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 is activated, there is an overload at the
output LC(x) - EXC+
Verify if the load cell link is not cut: wire is cut
Verify if the load cell is good
Verify if the load cell link length is below 100 feet (30.48m) with the recommended gage
If the problem persists, contact your AP/Cumberland or GSI Electronics
Issues with inputs
readings (LC(x) - SIG
+ and LC(x) – SIG-) Verify if the load cell wiring is conformed 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 is activated, there is an overload at the
output LC(x) - EXC+
Verify if the load cell link is not cut: wire is cut
