(※1) Reset mode : Automatic Reset ( A ): It will be reset automatically when reaching releasing pressure value.Manual reset
(※2) Low pressure switch delay time : If output is activated, it maintenances ON status during minimum ON time even under the OFF condition.
(※3) Oil Pressure Switch Set Value : Differential pressure( ODP ) = Oil pressure – Low pressure
(※4) Oil Pressure Switch Delay Time : Output will be activated after maintaining delay time which is set even though it is
(※5) Refrigerant selection : Display saturation temperature in accordance with selected refrigerant.
(※6) Offset : Offset the differential for pressure sensor. e.g)
If displayed pressure value: 2.0bar and actual pressure value: 2.2bar It is offset by inputting +0.2bar.

( H ): It will not be reset when reaching release pressure value unless users press RST button twice consecutively.
When input switch for compressor operation status (S1) is closed (Normally closed contact (N.C)),
it becomes an ON condition for OPS (Oil Pressure Switch Set Value) output if ODP (Differential pressure valve)is
less than OPS (Oil Pressure Switch Set Value). Output is de-activated if ODP (Differential pressure valve) is
higher than OPF (Oil Pressure Switch Releasing Value) after output is activated.
under the ON condition.
LED lamp will be turned on a light simultaneously with output after flickering during delay time.
