3.3.1.4 Operating Mode: Without Start/Restart Inter-
lock – Without External Device Monitoring
External wiring requirements:
Terminal 13 connected to 0 V
"Reset"
Terminal 14 connected to
"EDM" 24 V DC
Required DIP switch settings in
the MSI module (Chapter 3.2):
DS3 down DS2 up
After the supply voltage is app-
lied, the OSSDs immediately go
into the ON state if all of the
protected fields of the connected
AOPDs are free. In this case, the
start/restart interlock
and the dynamic monitoring of the downstream relays,
which may be required in order to maintain the safety
category, must be performed by other means.

ring
External wiring requirements:
Terminal 13 connected to 0 V
"Reset"
Terminal 14 connected to
"EDM" 24 V DC
Required DIP switch settings in
the MSI module (Chapter 3.2):
DS3 up DS2 up
After the supply voltage is app-
lied, the OSSDs remain in the
OFF state even if all of the pro-
tected fields of the connected
AOPDs are free.
When the protected fields of all connected AOPDs are
initially free, the OSSDs first enter the ON state when the
protected field of the AOPD connected at S1 (for Type 4:
S1 and S2) is interrupted and released. Only then do the
rest of the connected AOPDs respond to the interruption
and release of their own protected fields by switching the
OSSDs directly to the OFF and ON states.
In this case, the restart interlock function and the dyna-
mic monitoring of the downstream circuit elements, which
may be required in order to maintain the safety category,
must be performed by other means.
