The trip ranges shown are for
one wire pass through the
window opening. The trip range
may be proportionally lowered
with additional wire passes
through the window.

TRIP STATUS
EH - Energized on High, trips
when sense current is above trip
point and returns to non-trip
status when sense current is
below the trip point.
EL - Energized on Low, trips
when sense current is below trip
point and returns to non-trip
status when sense current is
above the trip point.
LH - Latch on High, trips when
sense current is above trip point
and remains tripped until
supply power is removed.
LL - Latch on Low, trips when
sense current is below trip point
and remains tripped until supply
power is removed.

TRIP ON DELAY
A - .5 to 6 Sec.
B - 2 to 25 Sec.
C - .1 to 1 Sec.
X - none
Time-on delay is the time from when the relay trips to
when the output energizes. The ranges are
guaranteed minimum, actual range may be slightly
greater.
