Regulating system
Description
When the compressor is started and the net pressure is below the setpoint, the motor speed
increases until the net pressure reaches the setpoint or until the maximum motor speed is
reached.
If the air consumption is less than the air delivery of the compressor, the net pressure increases
further.
When the net pressure reaches the setpoint (desired net pressure) and continues to rise, the
regulator decreases the motor speed.
When the pressure continues to increase although the motor already operates at minimum
speed, the regulator stops the motor as soon the net pressure reaches a value, equal to the
setpoint plus the indirect stop level (typically 0.3 bar above the setpoint).
Should the net pressure rise very quickly to a value equal to the setpoint plus the direct stop level
(typically 1 bar above the setpoint), the compressor is stopped immediately (without first
decreasing the motor speed).
See section
Programmable
No compressed air is lost when the compressor is stopped in automatic operation, thus saving
valuable energy.
If the compressor was stopped in automatic operation and the net pressure approaches the
setpoint, the regulator starts the motor again. The quicker the net pressure drops, the quicker the
compressor will restart.

Electrical system
Electrical components
The electrical system has the following components:
2920 7110 05
settings.
The pressure in the oil separator vessel is only released to atmosphere when the
compressor is stopped manually or in case of an emergency stop (see chapter Stopping
in section
Operating
Instructions).
