Abstract

Start up control system for compressors not fitted with incorporated output control, esp. cascade refrigeration machines, in which the compressor is conventionally fitred on its discharge side with an excess press. monitor and with a 2nd. press monitor, having an upper switch point below the excess press. point, neither monitor has reclose blocking, the excess press. monitor is connected to cut off the drive motor of the compressor, while the 2nd. press. monitor is connected to output-reducing devices, e.g. magnetic valves.
