5-10 Setpoint Programming and Operation

Example 1 – Simple demand management: To configure setpoint 1 to
energize output relay 1 when projected demand exceeds 100 kW for
more than one second and de-energize relay 1 when projected
demand falls below 90 kW for more than two seconds, you could use
the following settings.

Example 2 – Phase reversal relay: To use setpoint 2 to energize the
output relay as a permissive for starting a three-phase motor, you
could use the following settings.

ATTENTION

These examples are intended to demonstrate
setpoint configuration only. They should not be used
as sample application programming references.
Carefully consider all control, operational and safety
issues when designing and implementing setpoint
operations.
