Application Examples
2-channel safety gate monitoring.
Note: Refer to „Unit programming“!
Switches in pos.:
S1 no cross fault detection
S2 manual start
Suited up to SIL3, Performance Level e, Cat. 4
2-channel emergency stop circuit with cross fault detection
Note: Refer to „Unit programming“!
Switches in pos.:
S1 cross fault detection
S2 manual start
Suited up to SIL3, Performance Level e, Cat. 4
Contact reinforcement by external contactors, 2-channel controlled.
The output contacts can be reinforced by external contactors with forcibly
guided contacts for switching currents > 8 A.
Functioning of the external contactors is monitored by looping the NC
contacts into the closing circuit (terminals S33-S34).
Note: Refer to „Unit programming“!
