Information output signal attributes

The information output of the unit (terminal Y14) is set either high (+24 VDC) or low (0 VDC) depending on four
different input signals (terminal S1):
Dynamic signal - Dynamic signal input exist, i.e. the safety circuit is OK up until this unit
No dynamic signal - Dynamic signal input does not exist, i.e. the safety circuit is interrupted before this
unit.
+24 VDC - A constant +24 VDC signal is applied = high (H)
0 VDC - The pin is connected to 0 VDC = low (L)
The information output signal depends on the input signal according to the table below. Note that if the safety is
interrupted the information output signal is always low (L).
Input signal (S1)
Info output signal (Y14)
The delay for switching the information signal output from high to low (H

Warning! The information output signal is not a failsafe signal and should never be used for the safety purpose(s).
