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
The controller 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 within a given period of time are taken
into account.
The controller stops the compressor whenever possible to reduce the power consumption and restarts it
automatically when the net pressure decreases. If the expected unloading period is to short, the compressor
is kept running to prevent too short stand-still periods.
Protecting the compressor
Several sensors are provided on the compressor. If one of the measured signals exceeds the programmed
shutdown level, the compressor will be stopped or a warning is given.
Shutdown
Example: If the compressor element outlet temperature exceeds the programmed shutdown level, the
compressor will be stopped. This will be indicated on the display of the controller. The compressor will
also be stopped in case of overload of the drive motor or overload of the fan motor.
Before remedying, consult the Safety precautions.
