Protective door interlocked state [F-DI terminal 5 (channel 1), terminal 13 (channel 5)]
The door switch only interlocks if the actuator is inserted. The contacts of the monitoring
circuit then signal the status "closed and interlocked"
Signal state channel 1 = "1" and channel 5 = "1":
Protective door closed and interlocked.
Signal state channel 1 = "0" and channel 5 = "0":
Protective door not closed or not interlocked.

VS1: internal sensor supply for channel 0 to 3
VS2: internal sensor supply for channel 4 to 7
These two sensor supplies must be used when the short-circuit test is activated. The
exclusive OR sensor agreement button is an exception. For this sensor variant, in
conjunction with the short-circuit test, the VS1 sensor supply must be used for both contacts.
