Configuring ReLy reset
Overview
The following reset options for the safety relay are available:
•
Manual
For manual reset, a pushbutton is connected between the input S1 and the supply
voltage U
v
. Pressing the pushbutton manually for min. 140 ms triggers a valid
reset sequence at the S1 input.
•
Auto
For automatic reset, the S1 input and the supply voltage U
v
are connected with
a wire jumper. This automatically triggers a valid reset sequence at the S1 input.
There is no restart interlock.
