1.2 SUPERVISOR CONTROLLER, SUPERVISOR II AND WS CONTROLLERS
This manual describes sequencing of multiple compressors with Supervisor Controller,
Supervisor II Deluxe or WS Controller. The term "controller" is used to apply to any of
the three devices, however, specific differences will be highlighted in the places where
they apply. Although each controller differs considerably in individual compressor
functions and user interface, they behave similarly in sequence capabilities. Any of the
controllers can be mixed within a compressed air system consisting of multiple machines.
Refer to the specific controller instruction manual for details on compressor operation and
adjustment of the controller.
1.3 SEQUENCED COMPRESSOR SYSTEMS
Compressor sequencing refers to using multiple compressors to meet the demands for
compressed air. This may be a simple duplex system or may consist of multiple
compressors used in applications with widely varying demands. The main concept for all
configurations is for the compressors to operate automatically when compressed air is
needed and to automatically stop if not needed. A properly designed system can offer
substantial reductions in operating cost over a single large compressor.
Many duplex systems are designed with one primary compressor accompanied by one
spare compressor. This configuration allows the system to remain operational during
maintenance of a machine. The controller efficiently runs the compressors to meet the
varying demands during the day and runs the backup compressor only when needed.
The Supervisor, Supervisor II Deluxe, and WS Controllers all feature internal sequencing
functions. The Supervisor Controller requires a separate communications module for
these features. The machines operate as a distributed control system (rather than a
