5.
From the IN2 pull-down
menu, choose Start
Release.
Notice that Start Release is
shown connected to IN2.
Start Release is a feedback
circuit that confirms, at
Start – Reset, that neither of
the two final switching
devices (FSD)
normally-open (NO)
outputs are shorted, that is,
closed.
In this application, the Start
Release circuit goes from
+24V through one auxiliary
normally-closed (NC)
contact of each 100S
contactor to the MSR42
relay. Similar to EDM, if
either or both of these NC
contacts are open, the
MSR42 relay cannot be
started or reset.
6.
From the Outputs Info1
pull-down menu, choose
Micro 400 Light Curtain.
Status Micro 400 Light
Curtain is shown
connected to Info1. This
output switches High or
Low, depending on
whether the light curtain
beam is broken or
complete. This is
independent of the safety
output and can be
considered an auxiliary
output.
