O-Ring Seal - Siemens SIMOTICS A 1FU9 Operating Instructions Manual

Maintenance
10.5 Corrective maintenance
9. Calculate the gap between the solenoid and the armature disk as follows:
Gap = rotor thickness + s
10.Unscrew the sleeve screws evenly until the calculated gap between the solenoid and the
armature disk is reached.
11.Mount the new rotor and solenoid. Set the air gap of the brake, see Adjusting the air gap
(Page 120).
12.Connect the connection cable.
13.Mount the fan cover.
You have now replaced the friction lining of the brake.
