Setpoint Programming and Operation Chapter 5

Example 3 – Sag alarm. To set an alarm flag on a sag condition so that
RSEnergyMetrix software can log it and take action, use the following
settings.

Nominal system voltage is the nominal line to neutral voltage in Wye
and single-phase systems and nominal line to line voltage in Delta
systems. In 1404-M6 and 1404-M8 units, the high and low limits would
be the same as those found in setpoint 19, the built-in sag setpoint.
Setpoint release delay of 90 seconds sets alarm flag 3 long enough
that RSEnergyMetrix software can reliably log the alarm with a
one-minute log rate. Alarm flag 3 is selected because alarm flags 1 and
2 are tied to physical relay and KYZ outputs.

Configuring Setpoints by Using the Display Module

You may configure setpoint operations by navigating through the
PROG > PASS? > CONFIGURATION > SETPOINT menus, selecting a
setpoint number and programming the appropriate parameters.
