Two-pole emergency-stop with emergency-stop control device in the
supply circuit.
Application for long emergency-stop loops in which the control voltage
dropped below the minimum voltage of 21 V.
Important:
Single faults (line shorts over the emergency-stop control device) are not
identified with this external circuit.

Two-channel emergency-stop circuit with cross fault detection.
Please note "Unit programming" !
Switches in pos.:
Suited up to SIL3, Performance Level e, Cat. 4
Contact reinforcement by external contators, controlled with 2 contact
paths. With switching current > 10 A, the output contacts can be rein-
forced by external contactors with forcibly guided contacts. The function of
the external contactors is monitored by looping the NC contacts into the
making circuit (terminals S33-S34).
