ELECTRONIC OIL LEVEL REGULATOR 24V (1/2 NPT) (COM1-24/012)

Adequate oil level is an important requirement for long life of the compressor. Depending on the system design (eg. in rack applications) the correct oil level control under different operating conditions is possible only using an active regulation system. The passive systems are problematic because they only operate satisfactorily under constant operating conditions, but due to seasonal variations this is not possible.Variations in operating conditions and defrost cycles may be covered by an active oil regulation, ensuring reliable operation. Active systems monitor the oil level in compressors and generate an alarm for low oil level. Even without built-in compressor oil pump and oil differential pressure switch (for example, scroll compressor), the oil supply to the compressor can only be monitored with an active control.A Hall sensor and a built-in magnet in the float system measure the oil level in the compressor. Depending on the oil level and the consequent changes in magnetic field strength results in a variable voltage induced into the Sensor. This is evaluated by an electronic unit and accordingly, the LED’s and the solenoid valve will be actuated. If the oil level is in the alarm range (see operation), the COM switches with a delay time of 90 seconds the relays contact into the alarm state. This signal can be used to shut down the compressor or for data processing. During the alarm condition oil is permanently fed into the compressor, with the target to bring the oil level to normal. If successful, the alarm is reset.The installed software features a “Power on Logic”. During the first installation and power on of the oil controller the time delays for “Injection” and “alarm” are suppressed. This means a compressor having no oil at all, will result in an immediate injection of oil and at the same time switches into alarm. This is to avoid that such compressor does not run for the standard 90 sec. time delay until the alarm occurs.
