Abb. 40
• Remove fan cover (1)
• Remove plug (2)
• Measure air gap (S) with feeler gauge (F). N.B.: When measuring, ensure that the
feeler gauge is pushed in at least as far as depth "a" (see Tab.) and does not catch
on shoulder (!). See Tab. for max. permissible air gap (S). The brake is not adjusta-
ble. If the max. permissible air gap (S) has been reached, the brake disc (brake rotor)
must be replaced.
Replacing brake disc (brake rotor)
• Remove fan cover (1)
• Release clamp (3) of fanwheel (4)
• Disconnect brake
• Remove fanwheel (4)
• Remove V-ring (5) IP66
• Unscrew fixing screws (6)
• Remove magnet piece (7) together with armature disc (8)
• Remove brake disc (brake rotor) (9)
• Clean brake (wear a dust protection mask)
• Check friction surfaces for wear
• Push new brake disc (brake rotor) (9) onto hub (10) and check radial play. If there is
increased play in the gearing between brake disc (9) and hub (10) the hub (10) must
be pulled off the motor shaft and replaced.
NOTICE
Danger of damage
Always contact the manufacturer before removing the hub (10).
Replace in reverse order. Ensure that the check hole for measuring the air gap is under-
neath.
