Safety doors (1oo1 or 1oo2 evaluation)
For the Safety Doors, you can do one of the following:
•
Use F-DI application mode 1 with the fail-safe Y cable (6ES7194-6KB00-0XA0) to connect
two single-channel sensors with 1oo1 evaluation to one input connection of the F-DI
4/F-DQ 2 Fail-Safe module.
• Use F-DI application mode 3 (1oo2 evaluation), using two single-channel sensors on the
same safety door.
Alternatively, use F-DI application mode 5 with the fail-safe Y cable (6ES7194-6KA00-0XA0)
to connect two nonequivalent single-channel sensors with 1oo2 evaluation on the same
safety door.
Safety position switch with interlock (1oo2 evaluation)
Use F-DI application mode 3 and F-DQ application mode 1 to connect the safety position
switch with interlock to the F-DI 4/F-DQ 2 Fail-Safe module.
