(※1) Reset mode:
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.
(※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 = Oil pressure – Low pressur
e
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.
(※4) Oil Pressure Switch Delay Time :
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.
(※5)
Oil Pressure Switch Control Mode
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.
(※6) Refrigerant selection :
Display saturation temperature in accordance with selected refrigerant.
(※7) Offset :
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.
