Referencing the electronic hoist limit switch

Only with an electronic hoist limit switch

 

Referencing the hoist limit switch is a basic operation and has nothing to do with setting the upper and lower switching points, but is the reference point for all switching points.

The reference point is set at the factory. It must be reset if the chain and chain sprocket are replaced.

The saved switching points do not need to be reset after referencing.

The saved switching points are derived from the reference point that is set in this section. Consequently, the reference point should always be saved in the same place (bottom block or hook assembly just below the housing).

Since all the switching points are derived from the reference point, all the switching points can be corrected at the same time by changing the reference point accordingly.

 

 

 

Overview of referencing the hoist limit switch: (Described in detail below) ─     Switch off the chain hoist, wait 30 seconds, then switch on the chain hoist again. ─     Only with teach-in module: Remove the pendant control, plug in the teach-in module, wait 5 seconds, then remove the teach-in module and insert the pendant control. Only with pendant control with teach-in button: Press teach-in button for 5 seconds. Only with ABURemote AC with teach-in: Press “teach-in” direct access button (T with arrow) for 5 seconds. ─     Move to the reference point. This should be as high up as possible without the load hook coming into contact with the housing. ─     The last movement command before teach-in must be the “Lift” button. ─     Only with teach-in module: Remove the pendant control, plug in the teach-in module, wait 5 seconds, then remove the teach-in module and insert the pendant control. Only with pendant control with teach-in button: Press teach-in button for 5 seconds. Only with ABURemote AC with teach-in: Press “teach-in” direct access button (T with arrow) for 5 seconds.

 

 

 

 

 

Connection cable

   Loosen the bayonet nut and unplug the connection cable.

Or:

Switch off the chain hoist at the mains switch.

   Wait at least 30 s.

   Plug in the connection cable.

Or

Switch on the chain hoist at the mains switch.

 

 

Control cable	Bayonet nut
Teach-in module	Waiting time depending on the desired function

   Only with teach-in module: Loosen the bayonet nut and remove the pendant control.

   Plug the teach-in module into the control cable, press and hold the teach-in button on the pendant control, or press and hold the “teach-in” direct access button (T with arrow).

   Wait at least 5 s or more than 30 s:

─     If the waiting time is 5 s to 29 s, the hoist limit switch is referenced and the saved switching points are retained.

─     If the waiting time exceeds 30 s, the hoist limit switch is referenced. In addition, all saved switching points are deleted.

   Remove the teach-in module or release the teach-in button or "teach-in" direct access button (T with arrow).

●   Referencing (with or without deleting the switching points) has started. Continue with the next steps.

 

 

Control cable	Bayonet coupling
Emergency stop button	Pendant control

   Only with teach-in module: Insert pendant control.

   Only with teach-in module: Unlock emergency stop button.

 

 

Hook assembly or bottom block

   For the reference point, move up as far as possible without the hook block or hook assembly coming into contact with the housing.

   Finally, briefly press the “Lift” button.

Before teach-in, the “Lift” button must be pressed last if the reference point is to be set.

 

 

 

Control cable	Bayonet nut
Teach-in module

   Remove the pendant control.

   Insert the teach-in module.

   Wait at least 5 s.

   Remove the teach-in module.

 

   Only with pendant control with teach-in button: Instead of inserting the teach-in module, press and hold the teach-in button for 5 seconds.

   Only with ABURemote AC with teach-in: Instead of inserting the teach-in module, press and hold the “teach-in” direct access button (T with arrow) for 5 seconds.

●   The reference point is saved.

   Check the switching points (upper and lower) and correct if necessary.

─     The saved switching points are retained after referencing and therefore do not need to be reset.

─     If the switching points are moved equally, all the switching points can be corrected at the same time by changing the reference point accordingly.
