Commissioning the coupling
Measures to be taken prior to commissioning
Before commissioning the coupling check the proper installa-
tion of the flexible coupling elements, i.e. make sure the flexi-
bles are flush with the hub face, and check whether the set
screws are properly tightened. Also verify coupling alignment
and clearance S
1
and correct, if necessary. Check whether all
screwed connections have been tightening with the tightening
torques specified. Finally, fit the coupling guard against acci-
dental contact.
Operation
General operating data
During coupling operation, watch out for
·
changed running noises,
·
sudden vibrations.
If any irregularities occur during operation,
switch off the driver immediately and refer
to the trouble--shooting table to determine the cause.
The trouble--shooting table lists possible faults, causes and
suggested remedies.
