Process Control:
To activate external
lights,alarms or relays*
when a fault occurs, wire
them between dry relay
contact pins 5,4 & 3.
If the Lch function is ON
(set on the front panel),
the dry relay contacts will
remain closed until the
RESET button is pressed or
when pins 1&3 are closed
by remote switch
or relay. If the Lch
function is OFF, the dry
relay contacts will return
to normal state after the
interval known as the
PCd (Process Control
Duration, set on the front
panel) has elapsed.
