OVERRIDE FOR SG4-P
Override function allows the user to force safety function deactivation whenever it's
necessary to restart the machine despite one or more ESPE beams are intercepted.
The aim is clearing protected area of any working materials blocked ahead of ESPE
because of (i.e.) a cycle anomaly.
Override redundant inputs have to be connected to a 24VDC normally-open contact and
to a GND normally-open contact.
As the pertaining requirements request ESPE is equipped with two Override activation
inputs: OVERRIDE1 and OVERRIDE2 (respectively, pin 4 of the M12-12 poles connector
and pin 9 of the M12-12 poles connector - RX).
Figure 32 - Override connection
Necessary condition for override request to be accepted is: ESPE in SAFE state and at
least one Muting sensor intercepted.
When such condition is verified user interface visualizes “override attention status” with
both red OSSD led and alignment LEDs blinking.
