Fault Possible Cause Solution
Unit does not stop Brake not completely Cycle unit several hundred cycles to
accurately burnished burnish brake properly.
Not enough cycles Cycle unit several times to get braking
completed to get average distance calculation based on average
braking distance calculation number of cycles set point.
Unit does not stop at all Unit is not getting encoder Check that encoder is providing both “A”
signals and “B” signals to the control .
Check that encoder is providing “Z” pulse by
checking that home indicator LED flashes every
360 degree cycle.
Check that Z signal (home position) marker pulse
is between 50 and 450 counts. See “h” on
programming setup, page 11 .
Stop point varies from Brake output level set Set output level to brake higher by entering
cycle to cycle too low program mode and going to line 28 in
programming mode and increasing output level .
Brake is possibly worn out Check number of cycles on brake and
replace if worn excessively.
Count jumps when system Electrical noise being Determine source of electrical noise and
is at standstill generated and coupled to suppress appropriately .
control via wiring or air
Reroute control wiring if necessary and isolate
power and signal lines.
Excessive vibration on Check encoder mounting and isolate if
machine necessary .
During start, clutch does Clutch output level set too Set output level to clutch higher by entering
not seem to have enough low program mode and going to line 27 in
torque to drive load programming mode and increasing output level .
Clutch is new and has not Cycle clutch until burnish is obtained.
been burnished as yet Number of cycles will be dependent on
loading .
Clutch is possibly worn out Check number of cycles on clutch and
replace if worn excessively.
By no means does this cover every possible fault that could be encountered with the control and
clutch-brake. This is only a basic overview of the more common faults that occur with the control. If a
specific problem is encountered that cannot be resolved the best solution is to contact your local Warner
Electric Distributor, Representative, or the factory for further assistance in resolving your problem .
