TROUBLESHOOTING
General
: The chart below will be helpful when isolating exact problems which may occur in the control system . The chart
will also prove helpful when encountering problems with the initial start-up of the system . When the system has been
running for some time, the chart will also prove helpful when checking for worn, broken or frayed wires; bent or broken
control system parts; blown fuses; loose terminal connections and wire connections .
Sympton A:
Green LED indicator does not come on with power on .
Probable Cause
Solution
No power is applied to the control
Check that AC power is turned on .
Transformer wiring incorrect
Re-check wiring and correct if wiring is wrong .
Internal line fuse blown
Check fuse and if blown, replace .
No AC input power to transformer
Check for AC power to transformer .
Symptom B:
Red LED illuminates-short circuit .
Probable Cause
Solution
Shorted magnet coil
Check magnet coil resistance - approximately 66 ohms cold .
Remove shorted magnet coil and replace .
Brake connections improperly wired
Check wiring and rewire if necessary .
Transient noise
Check for source of noise and suppress .
Segregate wiring .
Use shielded cable .
