Maintenance Of Gearbox
The gearbox is maintenance-free.
Motor
The motor is maintenance-free under normal conditions, and it does not require any special inspection. Under more difficult conditions,
make sure that sufficient volume of air is provided to the motor at all times. For this, the unit must be regularly cleaned.
Electromagnetic brake
Maintenance of the disc brake is limited to checking the nominal air way (disk brake air gap).
The disc brake air gap should be between 0.15 and 0.60 mm. This guarantees short response times and low noise emission. The brake
must be replaced if the wear of the brake lining has aggravated to such an extent that the max. permissible air gap of the brake is
reached:
The following dimensions must be observed for the air passage:
• Measure the SLü air passage between anchor disk and magnet section with a feeler gauge.
• Compare the measured air passage with the maximum permissible air passage (for max. SLü, see Tab. 5).
• If necessary, replace the brake.
ATTENTION: Do not allow the brake friction pads to come in contact with lubricants, etc.
ATTENTION: While checking the air passage, the motor should be switched off and the unit should be without load.
Dismantling the electromagnetic brake
ATTENTION: The unit must be tension-free!
• Dismantle the hood (control) (item 2). To do this, loosen the four cylinder bolts (item 1).
• Dismantle the transformer or contactor control plate (item 3) (only for CPV/F 2-20 til CPV/F 20-4). For this, loosen the three screws.
• Detach the Allen screws (item 4) of the brake and pull the brake (item 5) out (detach the control wire from the circuit board resp. from
the connector).
• After replacing the spring action brake, check the nominal load.
