Installing the cross-type limit switch

Only with cross-type limit switch

This section only applies if the wire rope hoist has a cross-type limit switch in the trolley travel direction.

Where and for which travel limit the cross-type limit switch is designed is specified on the wiring diagram.

 

Danger due to malfunction! If the cross-type limit switch is screwed on too tightly, the parts on the inside can become jammed and no longer function properly. The tightening torque of 3 Nm must be strictly observed.

   Screw the mounting bracket onto the cross-type limit switch with the fillister-head screws M5x50 (2x).

   Screw on the mounting bracket using locking washers and M5 hexagonal nuts (2x). 3 Nm.

 

 

The cross-type limit switch is installed either on the trolley towing arm or on the trolley frame. The installation on the trolley towing arm is shown here. The installation on the trolley frame does not differ significantly.

   Turn the cross-type limit switch to position 0.

   The position of the cross-type limit switch is marked with an arrow that can be rotated further, depending on the switching state.

   Attach the cross-type limit switch in such a way that the switching lug will activate it.

The rotation direction of the cross-type limit switch for the respective travel direction must match the wiring diagram.

   Screw on the cross-type limit switch. 15 Nm.

 

 

   Route the connection cable (round cable or flat cable) from the cross-type limit switch to the panel.

   Route the connection cable with cable fitting into the panel.

   If necessary, connect the connection cable to a coupler plug or connector.

   Fasten connection cable with cable ties, cable grips and adhesive clips.
