Instruction book Refrigerant circuit Refrigerant compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (2) where most of the refrigerant condenses. The liquid refrigerant flows through dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary tube at evaporating pressure. The refrigerant enters evaporator (4) where it withdraws heat from the compressed air by further evaporation at constant pressure. -
Page 28: Elektronikon I Regulator
Instruction book Elektronikon I regulator Elektronikon I regulator Control panel Introduction In general, the Elektronikon regulator has following functions: • Controlling the compressor • Protecting the compressor • Monitoring components subject to service • Automatic restart after voltage failure (made inactive) Automatic control of the compressor The regulator maintains the net pressure between programmable limits by automatically loading and unloading the compressor.
-
Page 29: Control Panel
The regulator has a built-in function to automatically restart the compressor when the voltage is restored after voltage failure. This function is deactivated in compressors leaving the factory. If desired, the function can be activated. Consult the Atlas Copco Customer Centre. If activated, and provided the regulator was in the automatic operation mode, the compressor will automatically restart when the supply voltage to the module is restored.
