The parameters are to set the pressure and judgment time of over-pressure and under
pressure.
When the pressure of pipe network reaches the over- pressure threshold (determined by
PA.14), and it lasts for delay time (determined by PA.15), the system output alarm
signal(OP).After it, when the pressure is lower than the over- pressure threshold and it
also lasts for delay time (determined by PA.15), the alarm signal can be
