8.4.4.6 Test function for auxiliary switches
The 3KF provides a test function for mounted auxiliary switches that is supported by the 8UD
door-coupling rotary operating mechanism.
Note
You will find more details on the test function in chapter Auxiliary switches (Page 63).
Switching to the test position
The test position is located 20° counterclockwise from the OFF position and is mechanically
blocked to prevent accidental switching to this position when switching normally from ON to
OFF.
Procedure
1.
Press in the test position pin using a pointed object (with a diameter of 2 mm or less).
2. Keep the pin pressed and turn the handle into the test position.
Note
The pin can also be used for overriding interlocking in the ON position of the handle.
