Chapter 5 Setpoint Programming and Operation
Under Forward Setpoint
An under forward setpoint is similar to an over forward setpoint,
except the Setpoint High Limit and the Setpoint Low Limit are
reversed.
An under forward setpoint activates when the magnitude of the
parameter being monitored (defined by the Setpoint Type) decreases
below the Setpoint Low Limit and remains below the limit for a time
greater than the Setpoint Action Delay. The setpoint releases when the
magnitude of the parameter being monitored increases above the
Setpoint High Limit and stays above the limit for a time greater than
the Setpoint Release Delay.
