Introduction
The Elektronikon controller 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 operation
The controller maintains the net pressure between programmable limits by automatically loading and
unloading the compressor (on compressors running at a fixed speed) or by adapting the motor speed
(compressors with frequency converter). A number of programmable settings, e.g. the unloading and
loading pressures (for fixed speed compressors), the setpoint (for compressors with frequency converter),
the minimum stop time and the maximum number of motor starts and several other parameters are hereby
taken into account.
The controller stops the compressor whenever possible to reduce the power consumption and restarts it
automatically when the net pressure decreases. In case the expected unloading period is too short, the
compressor is kept running to prevent too short standstill periods.
A number of time based automatic start/stop commands may be programmed. Take into
account that a start command will be executed (if programmed and activated), even after
manually stopping the compressor.
