| Interlocked | Released | Open | Door closed and interlocked | |
Energized:
rapid access possible in the event of mains failure or wire breakage. Both contacts closed |
|
To unlock door | |
Apply voltage to coil (A1, A2), e.g. via zero-speed monitor, enabling contact (21–22) opens | ||
| Door open | |
Only possible once it is released, door position contact (11–12) opens | |||
| Door open | |
Both contacts blocked in the open position, even with tampering with simple tools | |||
| Closing of door | |
Triple coding actuator cancels blocking of the enabling contact, door opening contact (11–12) closes | |||
| To interlock door | |
Disconnect coil voltage:
1. Actuator interlocked 2. Enabling contact closed
|

 Switch must never be used as a mechanical stop! |
