The Cortex relays are controlled from fields called Controlled Output, as seen below. These boxes are found in many of the Cortex menus, particularly in the inputs.
To control a relay in one of the 4 ways listed above, use the following schemes:
1 – To command a relay as a follower, use the plain relay ID.
2 – To command a relay to pulse, add the letter P at the end of the relay ID.
3 – To command a relay to latch, add the letter L at the end of the relay ID (the relay must be RELEASED before it can be activated again).
4 – To command a relay to be released: add the letter R at the end of the relay ID.
