Special applications and
functions
4.10 Connecting S1, S2, S3
Three control inputs S1, S2, and S3 are available for the configuration of the control circuit
functions (restart interlock, retriggering, EDM) at the UE410-MU/UE410-XU modules.
No control inputs are available on the UE410-GU.
4.10.1 Operation with restart interlock
In the case of operation with a restart interlock the reset button is connected to the re-
spective input (S1/S2). The required starting condition for cancelling the restart interlock
is only fulfilled, when the reset button is pressed and released again and the feedback
circuit is closed.
4.10.2 Operation without restart interlock
The outputs are activated as soon as the input conditions of the safety sensors have the
value of logical “1”. A reset button is not required.
4.10.3 Operation with external device monitoring (EDM)
The static EDM monitors whether the controlled contactors have dropped out during re-
setting. The EDM is included in the feedback circuits S1, S2 and S3 in accordance with the
set program.
