Common Parameters
P1 and P2
P*217, P*227, P*237, P*247, P*257, P*267 - Relay Closures
This parameter will record how many times each relay is operated, this
parameter displays the number of times the relay has activated since the
relay has been in use. It can be reset with any value.
P*218, P*228, P*238, P*248, P*258, P*268 - Relay Fail Safe
Your Ultra Twin has a general fail-safe for each point of measurement,
parameter P1-808 or P2-808. However, this can be overridden so that each
individual relay has its own independent fail safe mode.
This parameter determines what the relay will do in the event of the Fail
safe Time (P1-809 or P2-809) expiring.
