Under Reverse Setpoint
An under reverse setpoint is the mirror image of an under forward
setpoint. The magnitude and all limits are negative numbers.
An under reverse setpoint activates when the magnitude of the
parameter being monitored (defined by the Setpoint Type) decreases
below the Setpoint Low Limit in the negative direction 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.
