OUTPUT PROGRAMMING
Setup of the alarms is fairly simple once a few concepts are under-
stood. Since the alarms can be set for reverse or direct action,
high or low function, and has normally open and normally closed
contacts; the number of combinations of actual output behavior is
quite large.
First, decide how you want the outputs to behave. Will the relay
energize or de-energize at the trip point? Will the relay trip on an
increasing or decreasing signal? Is the dead band above or below
the trip point?
It is impor tant to answer these questions before setting up the mod-
ule. The following Function Char t illustrates the most likely combi-
nations of settings.
