7.3 EDM function
The AOPD has a function for monitoring actuation external devices (EDM). This function can be activated or
deactivated (see paragraph 5
– “Electrical connections ”).
EDM activated:
1 ) Disconnect pin 3 of the connector or connect it to 0 V (EDM selection = ON).
2 ) Connect the EDM input (pin 4) to +24 VDC through the normally closed contacts
of the devices to be monitored.
EDM deactivated:
1 ) Connect pin 3 of the connector to +24 VDC (EDM selection = OFF).
2 ) Disconnect the EDM input (pin 4) or connect it to 0 V.
NB: The decimal dot on the display shows that the function is activated.
This function checks that the normally closed contact switches state when the OSSD
outputs change state.

– Time chart of the EDM function
T
C
and T
0
are the times between the change of state of the OSSD outputs and the change of state of the NC contact of
the external device.
T
C
≤ 350 ms: the external NC contacts must open within this time after the OSSD outputs have switched on.
T
0
≤ 100 ms: the external NC contacts must close within this time after the OSSD outputs have switched off.
