By carefully actuating the UP button on the control switch, check whether the wire rope was routed to the correct end of the fastening
hole. The rope must be wound tightly and uniformly. Cross-overs and entanglement are to be avoided. The optional rope guide
guarantees this.
Finally, the rope is to be lubricated along its entire length with a suitable lubricant.
Use simple multi-purpose oil or grease for lubrication.
Molybdenum disulphide (MoS2) or PTFE containing lubricants are not to be used.
Adjustment of the gear limit switch (optional)
If the lifting unit to be installed is equipped with a gear limit switch, the switching points must be adjusted to the use situation without fail
before the start-up. After adjusting these switching points, the rope winch and the load as well as the operator can be protected against
damage or serious injuries.
This setting could not be defined by the manufacturer because of the unforeseeable number of possible use scenarios.
NOTE: Depending on the customer's request, gear limit switches with up to 6 other actuation cams can be delivered. The gear limit
switch translation is to be selected according to the switching space (distance between the highest and lowest switching point).
Adjusting the slack rope switch (optional)
If the present rope winch is equipped with a slack rope switch, it must be adapted to the installation situation. In this connection, it is
advantageous to the operation-ready winch if a light load is fastened and then lifted for a short duration.
For horizontal rope outlet, the shifting roller is to be placed on the taut, downward wire rope from the top. On the side of the rocker
switch, where the switches are also placed, the control cam which is placed outside on the axle must be adjusted to the position of the
rocker switch. To do this, loosen the radially placed threaded pin on the control cam and turn the control cam in the anti-clockwise
direction, until the button switches.
NOTE: The switch is designed as an opener. As long as the contact wheel of the switch lies approximately at the centre of the flattened
piece of the switch cam, the sensor has not yet switched and all functions of the rope winch can be used without any restriction.
ATTENTION: Depending on the rope outlet and the installation position, the trip roller must be pressed to the rope if
necessary, through suitable measures (e.g. springs). Here, please make sure that the two rocker switches do not wrap each
other!

UNCTION CHECK AFTER INSTALLATION
Before the electric rope winch is put into regular service, the following additional inspections must be made:
Are all screwed connections on rope winch and the (optional) equipment secured tightly and locked?
• Does the wire rope lie uniformly and taut on the drum? There should be no twists, kinks and cross-overs!
• If the unit has an optional rope guide, its smooth working must also be checked.
• Does the information provided on the control organs match the actual movement directions of the rope drum?
• Does the EMERGENCY STOP button work?
• Unwinding and winding first in unloaded and then in loaded condition:
Does the rope always have sufficient distance from the disturbing edges?
Is the rope always wound and unwound uniformly?
Do a minimum 2½ safety windings remain on the rope drum even after full unwinding of the suspension material?
• Does the slack rope switch respond properly? Is it moved to its starting position reliably by a re-tightened rope?
• Is the gear limit switch set correctly?
The correct settings of the individual switching points are determined by the use conditions. The top most switching point must reliably
prevent the load hook from being drawn into the rope winch.
• Check the sliding clutch (optional, standard equipment in RPE 10-6) with a test weight (min. 125% of the rated capacity, max. 5 s).
Check the brake function when lifting and lowering. The braking distance must not be more than 50 mm.
The winch must also maintain its position under load, it should not slide.
