    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.
