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 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.
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.
Protecting the compressor
Shut-down
Several sensors are provided on the compressor. If one of these measurements exceeds the programmed
shut-down level, the compressor will be stopped. This will be indicated on display (1) and general alarm
LED (2) will blink.
