System Troubleshooting
A. Symptom:
Green LED indicator marked “Power” does not come on when power is applied to the CBC-200 Controller.
Probable Cause
Solution
No Power is applied to the Control
• Check that AC power is applied to the control.
• Incorrect wiring on AC power to the control.
• Check for 120 VAC at Terminals 2 and 3 with an AC Voltmeter.
Optional line fuse is blown
• Check for blown fuse – replace.
Indicator LED is defective
• Check for 120 VAC at Terminals 2 and 3 of the control.
• Check for output voltage at output terminals for Channel 1 and
Channel 2. If voltage is not present, replace control or board.
B. Symptom: Red LED marked “short” illuminates
Probable Cause
Solution
Shorted magnet coil
• Check resistance of magnet coil used and replace if necessary.
Wiring between control and magnet shorting
• Check for shorted conditions in wiring between the magnets and
the control, and wiring to chassis ground.
Improper magnet coil voltage
• Check magnet for proper coil voltage rating.
Transient noise
• Check for source of transient noise and suppress. Wire control
using shielded cables. Segregate wiring runs.
C. Symptom: Magnets do not engage when power is applied.
Probable Cause
Solution
External switching improperly wired
• Check wiring and switch connections and rewire if necessary.
Torque adjust set to zero (0)
• Set torque adjustment potentiometer to maximum level.
Current range switch improperly set
• Check DIP Switch settings per chart and reset if required.
No power applied to the control
• Refer to Symptom A above.
System incorrectly wired
• Check wiring per the wiring diagram and rewire if necessary.
Fail Safe brake used in place
• Check to insure that a fail safe brake is not being used in place of
of power applied brake
a power applied brake. Replace brake with correct brake.
D. Symptom: Magnets do not disengage when power is removed
Probable Cause
Solution
External switches incorrectly wired
• Check wiring of switching circuits and rewire if necessary.
Fail Safe brake magnet being used
• Check to see if fail safe brake is being used in place of power
applied brake.
Faulty control
• Replace control and see if problem is resolved.
E. Symptom: Magnets do not appear to have enough torque
Probable Cause
Solution
DIP Switch improperly set
• Check DIP switch setting per chart and reset if necessary.
Magnets incorrectly wired
• Check wiring between control and magnets and rewire if required.
Torque adjust potentiometer set too low
• Check setting of torque adjust potentiometer and set to maximum
if required. Check for correct wiring if external pots are used.
Magnets are incorrectly sized
• Verify sizing is correct by repeating selection process.
