Afterwards, the user has to fit a coupling protection con-
sisting of a fixed cover. The cover is intended to protect
the coupling especially from falling items. The covers can
be provided with regular openings. Following dimensions
must not be exceeded.
The distance of the cover to rotating parts must be at
least 5 mm. The cover must be electrically conductive and
must be included in the potential equalisation. The cover
is only allowed to be taken off during a halt. Aluminium
bellhousings (also with damping flange) are permitted as
connecting element, if the content of magnesium is less
than 7.5 %.
CAUTION!
When mounting the coupling to machines of cate-
gory 2D, please ensure that there is no dust be-
tween cover and coupling. The couplings must not
operate in dust particles. When using the coupling
in machines of group I, category M2, the cover must
not consist of light metal (higher mechanical load).
During operation of the coupling please pay attention to:
•
Changed operation noises
•
Occurring vibrations
ATTENTION!
In case of changes or irregularities during the opera-
tion of the coupling, the power unit must be switched
off immediately. The cause of the disturbance must
be found out by the check list ”Trouble in service”
and be removed, if possible.

6.6 TROUBLE IN SERVICE / CAUSES AND CLEARANCE
A disturbance by break of the fixing screws of the flange
couplings must be excluded under observance of the
selection criteria.

High temperatures
at the surface lead to
an ignition risk
• Stop the unit
• Check and remove changes in construction
• Check the drive unit for damages
• Check and correct, if necessary, alignment and dimension
E of the coupling
• Check the wear of the gear ring and exchange,
if necessary
Loose screws for axial
securing of the hub
Ignition risk by hot surface
and sparking
• Stop the unit
• Check and correct alignment and dimension E of the
coupling
• Check the wear of the gear ring and exchange,
if necessary
• Retighten the fixing screws by the starting torque and
protect it from self-loosening with Loctite
