Under Forward Setpoint
An under forward setpoint is the same as an over
forward setpoint, except the “Setpoint High Limit”
and the “Setpoint Low Limit” are reversed.
When the magnitude of the parameter being
monitored falls below the “Setpoint Low Limit” in
the positive direction (and stays below the limit) for a
period of time greater than the “Setpoint Action
Delay,” the setpoint becomes active. An under
forward setpoint becomes inactive when the
magnitude of the parameter being monitored exceeds
the “Setpoint High Limit” (and stays over the limit)
for a period of time greater than the “Setpoint
Release Delay.”
