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 regulator maintains the net pressure between programmable limits by automatically loading and unloading
the compressor. A number of programmable settings, e.g. the unloading and loading pressures, the minimum
stop time and the maximum number of motor starts are taken into account.
The regulator 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.
