7.1 Normal operation of the coupling7.1 Normal operation of the coupling
During normal operation, the coupling runs vibration-free.
7.2 Fault – causes and correction7.2 Fault – causes and correction
A form of behaviour which is different to normal operation is classed as a fault and has to be
rectified immediately.
Look out specifically for the following faults during coupling operation:
• Unusual coupling noise
• Sudden occurrence of shocks
7.2.1 Procedure in the event of faults7.2 Fault – causes and correction
DANGER
Danger due to bursting of the coupling
There is a risk of fatal injury from flying fragments. Bursting of the coupling can lead to an
explosion in potentially explosive atmospheres.
• Switch off the unit at once if any faults occur.
• Note during the repair work the possible causes of faults and the notes on rectifying
them.
Proceed as described below if there is a fault of the coupling during operation:
1. Turn the drive off immediately.
2. Initiate the required action for repair taking into consideration the applicable safety regu-
lations.
If you cannot determine the cause or if you cannot carry out repair work with your own
means, request one of our customer service technicians.
