Troubleshooting
Only Authorized Personnel to Set Up and Maintain this Unit.
The CBPC-3590 control has several internal diagnostic features that illuminate an indicator light showing
fault condition and a fault indication on the display . Once a fault condition occurs, the control has to be
opened to access the display panel and read the fault condition. Not every fault that is possible will be
displayed with an indication, only the most prevalent ones.
The following conditions will cause the front panel fault LED to illuminate and the fault relay internal to
the control to drop out .
Fault Display Corrective Action to be Taken
Low Voltage Lo Volt After normal voltage is restored, unit
returns to normal operation .
Red fault LED “On”
Fault Relay drops out
Feedback too fast Error 2 Reset clears fault.
Speed or encoder resolution must be reduced
Red fault LED “On” or corrected to prevent further errors .
Fault Relay drops out
Process time fully Error 3 Reset clears fault .

Additionally, other faults can occur with the CBPC-3590 which can effect the operation of the system. Some common
faults that could occur are listed below.
Fault Possible Cause Solution
Count direction negative Encoder signals “A” and Reverse signal “A” and “B” wiring on
rather than positive “B” reversed encoder connector plug .
Unit does not start when Start signal voltage Check switching voltage on start input
external start signal is incorrect or not present line (120 VAC) or make sure start switching
applied circuit is functional .
If system will start with start key on keypad,
then fault is external to the control .
Control does not operate No power to control Check that power light in “On/Off” switch is
turned on .
Check that the AC power is applied to control
at control cable .
Check fuse.
Check that “On/Off” power switch is turned on.
Clutch-Brake not connected Check that the clutch-brake is mounted and
connected to output of control .
Cables are not connected Check that both encoder cable and power/
to control CI-Bk cable is connected to controller.
