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.
The function “Override travel limit switch” is protected by a PIN or a key switch.
To unlock a protected function:
Either:
For function protected by PIN: When switching on or logging in the transmitter, enter the correct PIN for PIN level 1 or PIN level 3. See Entering the PIN.
Or:
For function protected by key switch: Insert the key in the switch and turn it. See Operating additional functions on the crane using key switches.
● The protected function is unlocked.
● The direct access button has a black background. The protected function “Override travel limit switch” can now be used.
