Section II - General Description
Regulating system
Description
If the vacuum process demand is less than the throughput of the vacuum pump, the
vacuum pressure decreases. When the pressure is lower than the set-point (desired
vacuum pressure), the regulator decreases the motor speed.
If the vacuum pressure decreases and the motor operates at minimum speed, the
regulator stops the motor. When the motor is stopped automatically and the vacuum
pressure comes to the set-point, the regulator starts the motor again.
Boost version
The regulation system of the Boost version is designed to handle fast cycling duties.
When the vacuum pressure reaches the set-point, the regulator will keep the motor
running at increased speed for an adjustable time before the regulator decreases the
motor speed.
