II regulator
Control panel
General
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. If 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
If the compressor element outlet temperature exceeds the programmed shut-down level, the compressor
will be stopped. This will be indicated on display (1) and general alarm LED (2) will flash.
The compressor will also be stopped in the event of overload of:
• the drive motor
• the cooler fan motor of air-cooled units
Remedy the trouble and reset the message. See also the Status data menu.
