The OUT580-H1 oil level regulator is a self-contained system which provides both functions of oil level monitoring and active oil level balancing including alarm relay activation for compressor protection.

Function

OUT580-H1 uses a Hall-Sensor to measure the oil level. A magnetic float changes its position according to the oil level, not prone to errors by foaming or light. The hall sensor converts these magnetic field changes into an equivalent signal and lower yellow LDE, which is used by the electronic controller to open or close an external solenoid valve which feeds missing oil directly into the compressor sump, when the oil level drops in to the yellow zone.

If the oil level drops into the red zone, the upper LED  become orange and after a delay 90 seconds. OUT580-H1 generates an alarm signal, the alarm contact (SPDT) changes into alarm state and the upper LED become red, the alarm contact may be used to shut down the compressor. If the oil level comes back to normal, the alarm will be reset.
