Automatic Reset (A ): It will be reset automatically when reaching releasing pressure value.
Manual reset (H ): It will not be reset when reaching release pressure value unless users press RST button twice consecutively.
If output is activated, it maintenances ON status during minimum ON time even under the OFF condition.
Differential pressure = Oil pressure –Low pressure
It becomes an ON condition for output if differential pressure valve (DP) is less than oil switch pressure switch set value (OPS). Output is de-activated if
differential pressure value (DP) is higher than oil pressure switch releasing value (OPF) after output is activated.
Output will be activated after maintaining delay time which is set even though it is under the ON condition.
LED lamp will be turned on a light simultaneously with output after flickering during delay time.
Control mode for oil pressure switch: In case of using control mode for oil pressure switch as 0-L (OP – LP),
it can be come to a output state of OPS due to pressure equalizing at the status of compressor stop.
Display saturation temperature in accordance with selected refrigerant.
Offset the differential for pressure sensor.
e.g) If displayed pressure value: 0.20MPa and actual pressure value: 0.22MPa It is offset by inputting +0.02MPa.
