Information output signal attributes

The information output of the unit (pin-5, Vital/Pluto connector) is set either high (+24 VDC) or low (0 VDC)
depending on four different input signals (pin-2, Vital/Pluto connector):
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)
When OSSD1 and OSSD2 are both high, the information output signal depends on the input signal according to
the table below. Note that if the safety is interrupted on the device connected to this unit, the information output
signal is always low (L).

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