7 Operation
7.1 Special safety guidelines
CAUTION
Risk of accidents due to non-observance of the safety guidelines
There is a risk of accidents if the general safety guidelines are not observed.
► All safety guidelines must be observed, see section 2.
7.2 Initial commissioning
Perform control
measures 1. Check the correct use of oils and grease, see section 6.3.
2. Before commissioning, check that the adjusted air gap (La) has been retained even after
several switching operations, see section 6.3.2. The clutch must be switched on approx.
five times and the air gap (La) must be checked at two opposite points. If the air gap
changes due to setting processes or unequal axial securing, and no longer corresponds to
the specified value, the air gap must be reset and the axial securing must be checked if
necessary.
3. For clutches in wet operation, clean the gearbox carefully before commissioning until all
metal shavings that are potentially inside have been removed.
Removal of the
laminated pro-
tective foil The product designation for some components is done through the laminated protective label.
These labels consist of a self-adhesive polyester foil, for which the print image is protected
from external effects by a transparent foil. As the products are partially laminated only after
the designation, the labels are equipped with a second, lightly removable laminated protec-
tive foil. This can be easily removed after lamination using a handy tap. If the laminated pro-
tective foil is not removed, it automatically comes away after 1 to 2 years, as it is not equip-
ped with a long-lasting glue.
NOTICE
Damage to the surrounding construction due to failure to remove laminated
protective foil
The laminated protective foil can detach and lead to the following damage to the surrounding
construction, when not removed.
► Detach the laminated protective foil using the handy tap.
1. Detach the laminated protective foil (if present) using the handy tap.
NOTE
When switching on the clutch, tooth tips can end up on top of other tooth tips. The teeth then do not
engage in the opposite tooth gaps. In this position, the tooth clutches only transmit approx. 10 - 20%
of their nominal torque. An engagement of "tooth in gap" can only then occur when a rotation of the
input side is introduced and the load torque is greater than approx. 20 % of the nominal torque of the
clutch for small output side masses. For larger output-side masses engagement occurs also for small-
er load torques.
A quick switching essentially improves the switching process.
7.3 Duty cycle, switching frequency and switching times
The clutch is suitable for continuous operation, provided the permissible limit values were observed in the con-
struction. To ensure trouble-free operation, the technical specifications must be observed, see section 4.
Switching breaks are not required when the construction of the clutch has been carried out correctly.
