Overriding travel limit switch of a bypass control

 

Only with override travel limit switch

 

Using the “Limit switch” function, the travel limit switch of a bypass control (e.g. for tall machines which the crane is usually not allowed to travel over) can be overridden. The crane can then be moved into the blocked area at a slow speed (e.g. to set up the machine).

This function can only be opened using a direct access button.
