• Automatic restart after voltage failure (made inactive)
Automatic control of the compressor
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 to short, the compressor
is kept running to prevent too short stand-still periods.
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 the display of the regulator. The compressor will also be stopped in case
of overload of the drive motor.
Air-cooled compressors will also be stopped in the event of overload of the fan motor.
Shut-down warning
A shut-down warning level is a programmable level below the shut-down level.
