The INT280-60 Diagnose is a further development of the reliable KRIWAN oil level regulators. The oil level regulator INT280-60 Diagnose monitors and controls the oil level in the refrigerant compressors. The problem of poor oil distribution in multicompressor packs has been overcome by actively supplying oil from the oil reservoir. This minimizes the risk of operating without enough oil in the compressor. The INT280-60 Diagnose saves operating and error data in a nonvolatile memory. This data can be read and evaluated for diagnosis.

Functional description

If the oil level is too low, the intelligent filling algorithm controls the oil refill. To do this, the integrated solenoid valve is opened cyclically. The oil level regulator switches the compressor off through the internal relay if the oil level remains too low after an extended period of time. Oil refilling continues after this. When the oil level is sufficient the relay tightens, the compressor can start again. The reactions are time delayed, to prevent unnecessary switching in response to temporary fluctuations in the oil level. The INT280-60 Diagnose has its own monitoring system of the optical sensor. In the event of malfunctions or soiling, the relevant warning or error will be notified. Selected parameters (see table of parameters) are adjustable via the Diagnose Port with the aid of the INTspector. A connection to a Diagnose compressor protection unit can be created via the Diagnose Port. The oil level regulator optimises its behaviour using the data from the compressor protection unit, e.g. it only sounds an alarm for a lack of oil when the compressor is running. The integrated LED signals the current status. For operation in the specified manner, the supply voltage has to be on permanently on the INT280-60 Diagnose.
