•
Two-channel emergency stop monitoring
•
Automatic start
•
Monitoring of external, force-guided contactors
•
No cross-circuit detection in the sensor circuit
•
Suitable up to category 4, PL e (EN ISO 13849-1), SIL 3 (EN 62061), if
cross-circuits in the control to the actuator and the sensor circuit can be
ruled out.
Figure 15:
Emergency stop monitoring / automatic start / without cross-circuit detection
Key:
Cross-circuits in the cable installation can be excluded if the
safety relay and external contactors K1 and K2 are located in the
same electrical installation space.
For sensor circuits in the field, prevent cross-circuits by using a
cable installation that is protected mechanically.
