2) Pressure command is to decrease the pressure
3) The elapsed time is longer than time set at Pr.00-63.
4) The feedback pressure doesn’t reach yet the stable pressure zone.
Use Pr.00-63 to set up the time interval between opening and closing pressure releasing valve to avoid
unnecessary valve opening and closing (ON / OFF)
