Introduction
The controller has following functions:
•
Controlling the compressor
• Protecting the compressor
• Monitoring components subject to service
• Automatic restart after voltage failure (made inactive)
Automatic control of the compressor operation
The controller maintains the net pressure between programmable limits by automatically starting
and stopping one or more compressor modules. A number of programmable settings, e.g. the
starting and stopping pressures and the maximum allowed motor starting frequency and several
other parameters are hereby taken into account.
The controller stops the compressor whenever possible to reduce the power consumption and
restarts it automatically when the net pressure decreases.
A number of time based automatic start/stop commands can be programmed. Take into
account that a start command will be executed (if programmed and activated), even after
manually stopping the compressor.
Protecting the compressor
Shutdown
Several sensors are provided on the compressor. If one of the measured signals exceeds the
programmed shutdown level, the compressor will be stopped. This will be indicated on display (1)
and general alarm LED (2) will blink.
