DISARMED This is the second step,
after the "DISARMED
Ctrl" has been activated,
that is required to
DISARM the relay

DISARM those output
relays that are currently
not latched and that are
not on “hold” by a
pending minimum hold
time. CAUTION!
RELAYS DISARMED in
order to safely perform
maintenance while
eliminating the risk of
taking an entire process
off-line. (Note: Zone

YOU MUST ENSURE
that the relays are
ARMED AGAIN after
maintenance.

the normal Output Relay
State can be overwritten

according to the assigned
signals) to "force
energized" or "force de-
energized" state. Forcing
all outputs relays of an
entire assembly group is
superior to forcing a
single output relay. Normal,
