8.2 Pressure Roll

Check the correct position (suitable for the cable outlet) before
initial commissioning. The spring pretension can be adjusted
via elongated holes.

8.3 Slack Rope Switch

GB
Interrupts the drive, as soon as the rope loses its tension,
e.g. if the load jams when „lowering" or reaches the ground.
Prevents the rope coils jumping off the drum. Prevents during
renewed lifting cross layering of the rope. (rope damage).
not available for divided drums!
The slack rope switch is made of a spring mounted roll arm
If the rope loses its tension, then the limit switch
by a cam segment. The motor stops.
With known rope outlet, the slack rope switch has been adju-
sted in the factory.
z Configure the switch to local conditions and check its func-
tion prior to initial commissioning. In order to do so, release
the clamping screws

screws again. Subsequently release the stud bolt

the trip cam . Move the trip cam into a position in which
the limit switch  is actuated, but where it can be moved
into a non-actuated position due to the action of the tensio-
ned rope. Engage the stud bolt
The slack rope switch has already been connected according
to the circuit diagram, if the control unit has been supplied by
the factory. Otherwise it is the responsibility of the operator to
correctly connect the switching element to the control unit.
The slack rope switch is a safety component.
– Examine regularly, however at least once annually, as well
as before commissioning.

8.4 Emergency Hand Operation

The motor brake starts automatically, if the power supply is
interrupted. The load movement is stopped immediately.
Lower load:
z Screw in brake lever, vent brake.
Lift load:
z Attach crank to motor, turn anti-clockwise , vent brake.
Emergency hand operation only when disconnected
from power supply.
Exceptional situation! Therefore special attention is
necessary. –>Safety instructions in Chapter 2.
Only assign instructed personnel.
Do not stay under suspended loads or in the danger
area. Secure danger zone.
LOWERING - NOTE!
The load starts moving independently after venting
the brake. The load is braked again by releasing the
brake lever. Do not exceed suitable lowering speed.
Only lower load step by step!
If necessary, use the provided crank for lowering.

Inserting the crank interrupts the power supply of the motor.
The appropriate switch has already been connected accor-
ding to the circuit diagram, if a factory control unit is installed.
Otherwise it is the responsibility of the operator to correctly
connect the switching element to the control unit.
The switch is a safety component.
– Examine regularly, however at least once annually, as well
as before commissioning.
The operator must ensure, that the brake is not inad-

vertently vented during normal operation.
e.g. the lever can be unscrewed with 400 V drive units
and screwed in into the crank mounting.
