Application Examples
Two-pole emergency stop circuit with emergency stop control device in
supply circuit with automatic ON-function.
Application for long emergency stop loops where the control voltage drops
below the minimum voltage of 21 V.
Attention:
Single faults (e.g. line faults at the emergency stop control device) are not
detected with this external circuit configuration.
Suited up to SIL2, Performance Level d, Cat. 3
Contact reinforcement by external contactors, 2-channel.
The output contacts can be reinforced by external contactors with forcibly
guided contacts for switching currents > 10 A. Functioning of the external
contactors is monitored by looping the NC contacts into the closing circuit
(terminals Y2 - S12).
Suited up to SIL3, Performance Level e, Cat. 4
Single-channel emergency stop circuit. This circuit does not have any
redundancy in the emergency stop control circuit
Suited up to SIL2, Performance Level d, Cat. 3 Two-channel emergency stop circuit with cross fault detection.
Activation via On pushbutton. ---- Jumper X5 -X6:
Jumper X5 - X6 must be fitted for the automatic On function.
The On pushbutton is not required.
Suited up to SIL3, Performance Level e, Cat. 4
Two-channel monitoring of a safety gate.
Suited up to SIL3, Performance Level e, Cat. 4 Two-channel emergency-stop circuit without cross fault detection.
Activation via On pushbutton. ---- Jumper X5 - X6:
Jumper X5 - X6 must be fitted for the automatic On function.
The On pushbutton is not required.
Suited up to SIL3, Performance Level e, Cat. 4
