Example for P2 = H.L.
If the alarm is programmed as band or deviation, this function masks the alarm condition at start up and at a “Su” setpoint change until the process variable reaches the alarm threshold, plus or minus hysteresis. This standby function masks a Process Alarm condition at start up until the process variable reaches the alarm threshold plus or minus hysteresis.
