1.4.1 Main functions
1.4.1.1 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.
1.4.1.2 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 (3). The compressor will
also be stopped in case of overload of the drive motor (M1)
and the fan motor (M2).
Shut-down warning
If the compressor element outlet temperature or dewpoint
temperature (Full-Feature) exceeds a programmed value below
the shut-down level, this will also be indicated to warn the
operator before the shut-down level is reached.
