conrm output.

When the cover is extended, APC pin 2 output is low and inhibit is active (probe inhibited).
When the cover is retracted, APC pin 2 output is high and inhibit is off (probe not inhibited).
NOTE: The retract conrm output must be connected to the machine tool controller; for more
information see “Connecting the APC to an HSI interface and the CNC” on page 10 or “Connecting
the APC to an HSI-C interface and the CNC” on page 11.
