Introduction
The Airlogic controller has following functions:

Controlling the vacuum pump

Protecting the vacuum pump

Monitoring components subject to service

Automatic restart after voltage failure (made inactive)
Automatic control of the vacuum pump operation
The controller maintains the pressure within programmable limits by automatically adapting the motor
speed. A number of programmable settings, e.g. the set point, the minimum stop time and the maximum
number of motor starts and several other parameters are hereby taken into account.
The controller stops the vacuum pump whenever possible to reduce the power consumption and restarts it
automatically when the pressure decreases. For High Water Handling Capability pumps, the pump is
equipped with a purge cycle which prevents and removes condensed water in the sealing oil.
CAUTION!
A number of time based automatic start/stop command may be programmed. Take into account
that a start command will be executed (if programmed and activated), even after manually stopping
the vacuum pump.
Protecting the Vacuum pump
Shut-down
Several sensors are provided on the vacuum pump. If one of the measurement succeeds the programmed
shut down level, the vacuum pump will be stopped. This will be indicated on display (1) and general alarm
LED(2)will blink.
Remedy the trouble and reset the message. See also the Inputs menu.
