Timeout (sec): Used to set the time, between 10 sec and infinity, by which the Override function
must end.
Override mode: Used to configure the type of Override (pulsed or maintained action).
With OverOut: Used to activate an Override active Signaling output (active when high).
With Request: Used to activate a Signaling output (active when high) indicating that the Override
function can be activated.
Manual Reset:
•
Should the INPUT be active (TRUE), the reset enables the output of the function block.
•
Should the INPUT be not active (FALSE), the output of the function block follows the
OVERRIDE request.
There are two types of reset: Manual and Monitored. When Manual is selected the system only
verifies the signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to
1 and then back to 0 is verified.
