Safety inputs
−
1 channel for safety switches with one dry contact, evaluation 1oo1
−

−
2 channels for safety switchgear with 2 OSSDs and test pulses,
evaluation 1oo2
Cross fault monitoring
−
ON for safety switches with one or two dry contacts
−
OFF for safety switchgear with electronic OSSDs
WARNING
The default setting is used for safety switchgear with electronic OSSDs.
If safety switchgear with dry contacts are used, cross fault monitoring
must be activated!
WARNING
For safety switchgear with electronic OSSDs, cross fault detection of the device
connection cable must be carried out by the safety switchgear!
