Safety current circuit (normally open)
The activation and input contacts have to be wired according to the intended purpose (s. of " assembly
and line-up "). For the operation of the device, it must be connected with the Inline system. Over the Inline
bus terminal or a inline power terminal the voltage supply of 24V/DC is taken over. It lights up the LED
"UM".
For the start the terminals Y1 and Y2 have to be bridged (Feedback loop circuit control). The safety
device SAFE ILZ activates the safety current circuits only if the loop back circuit (Y1-Y2) is closed.
