Introduction
The Elektronikon controller has following functions:
• Automatic compressor control
• Compressor protection
• Service warning
• Automatic restart after voltage failure (disabled)
Automatic compressor control
The controller keeps the net pressure between adjustable boundaries by automatically loading and
unloading the compressor. A number of adjustable settings, e.g. the (un)loading pressure, the minimum
stop time and the maximum number of motor starts are taken into account.
The controller switches the regime to unload when the selected unloading pressure is reached and stops the
compressor to reduce power consumption when it has been running unloaded for a given time. In case the
net pressure drops down to the loading pressure while the compressor is running unloaded, the compressor
is kept running and switches to load to avoid short standstills and energy waste.
When the compressor has stopped automatically and the net pressure decreases, the controller will start the
compressor before the net pressure has dropped to the loading pressure to prevent the net pressure from
reaching the programmed minimum level. When stopping the compressor manually, the controller will
unload the compressor for a given time and then stop the compressor.
A number of time based automatic start/stop commands may be set. Be aware that a
start command will be executed (if set and enabled), even after manually stopping the
compressor unit with the controller.
