Oil differential pressure sensor ICG571C series
APPLICATION:
Oil differential pressure sensor is designed to detect and ensure a sufficient oil quantity in compressors. The evaluation unit can be detached separately.
FUNCTIONAL DESCRIPTION:
* The ICG571C oil differential pressure sensor is composed of a screw-in unit and an evaluation unit. The screw-in unit is directly screwed into the pump shell of the compressor, and its internal channel is connected with the compressor oil system.
* Once the supply voltage is turned on, the relay is turned on after 3 sec. delay, then LED turns orange; when the evaluation unit is not connected with the screw-in unit, the relay is turned off and red LED light flashes. When the compressor operation signal D1 is on (see the wiring diagram), the pressure differential starts to be monitored.
* When the oil pressure differential is OK, the LED turns green; when the oil pressure differential is too low, the LED turns orange, and starts timing. If the oil pressure differential is lower than 0.65bar (the fixed value of the screw-in unit) for 90sec, the red LED turns on and the relay will be turned off and self-locked, then the compressor will be stopped to prevent damage.
