Problem Solution
The EDGE Bin Scale does
not communicate Verify if the EDGE Bin Scale is powered up
Verify if there are activity on the bus communication by looking at the activity of
the LEDs: LED4, LED5, LED6, LED7 on the PCB-415 inside the EDGE Bin
Scale or by looking at the LEDs on the OLED Display of the EDGE Bin Scale
Verify if the network link is installed correctly: Terminal A from EDGE Bin Scale
to the controller terminal A, Terminal B from EDGE Bin Scale to the controller
terminal B
Verify if the network communication is installed in daisy chain.
Verify if your end of line (EOL) switches are set correctly on your network
Verify if the network link has been severed or the protections have been
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 recom-
mended wire gauge.
Measure the voltage between the terminal 24V and GND on the EDGE Bin
Scale terminals. The voltage must be at least 16V
If the problem persists, contact AP/Cumberland or GSI Electronics
The EDGE Bin Scale does
not power up Verify if the LED "5V" is activated on the PCB-415 inside the EDGE Bin Scale or
by looking at the LEDs on the OLED Display of the EDGE Bin Scale
Measure the voltage between the terminal 24V and GND on the EDGE Bin
Scale terminals. The voltage must be at least 16V
Verify if the power link is installed correctly: Terminal 24V from EDGE Bin Scale
to the controller terminal 24V, Terminal GND from EDGE Bin Scale to the con-
troller terminal GND
Verify if the power link has been severed.
Verify if the power link length is below 300 feet (1000m) with the recommended
wire gauge.
If the problem persists, contact AP/Cumberland or GSI Electronics
Issues with the voltage output
to power the load cell (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 terminals
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 is good: The voltage must be higher than 0,3V
Verify if the load cell link length is below 50 feet (15m) with the recommended
wire gauge.
