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.

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).
