In this operating mode, the output relay coils will de-energize upon
the closure of conductors within the monitored sensor/switch system.
The coils will not energize again until the closure is broken and a
RESET signal is manually generated by the operator (via a mechanical
N.O. pushbutton or switch).
3.

In this operating mode, the RESET signal cannot propagate
unless
all
of the following conditions are met:
-
The contacts have opened in the monitored sensor/switch.
-
The machine primary control elements (MPCE 1 and MPCE 2)
have closed.
-
A manual RESET signal is subsequently generated by an
operator
pressing the “Start” pushbutton.
