Description
LED on Adam

Green-Red (flash)
Eva close, safety circuit broken by a previous unit
Green-Red (flash fast)
Eva within ~2 mm of max sensing distance
Red
Eva distant, safety circuit broken
Information output signal attributes
When Eva is in contact with Adam, the information output of the unit (pin-5) is set either high (+24 VDC) or low (0
VDC) depending on four different input signals (pin-2):
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 co24 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, i.e. if Eva is away from Adam, 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).
