1.1 SAFETY

1.2 SUPERVISOR CONTROLLERS

This manual describes sequencing of multiple compressors with Supervisor or Supervisor
II Deluxe electronic controllers.  Although these differ considerably in individual compressor
functions and user interface, they behave similarly in sequence capabilities, and can be
mixed within a compressed air system.  This manual will use the term "controller" to apply
to either device, and will highlight specific differences in the few places where they apply.
Refer to the controller manuals 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 be multiple compressors for
applications with widely varying demands.  In any case, the compressors automatically stop,
if not needed, to reduce operating costs.  A properly designed system can offer substantial
reductions in operating cost over a single large compressor.  Many systems are designed
with one spare compressor, allowing the system to remain operational during maintenance
of a machine.  The controls system does the job of efficiently running the compressors as
needed to meet the varying demands during the day, or to run the backup compressor only
when needed.

Supervisor and Supervisor II Deluxe controllers all feature internal sequencing functions.
Supervisor requires a communications module for these features.  These operate as a dis-
tributed control system (rather than a master-slave relationship), so the system remains
operational even if a member is taken off-line.  Refer to Section 2 for details.

A system with one or more variable-speed compressors offers some additional opportuni-
ties for control.  Refer to Section 3 for details.

For information specific to the Supervisor Controller or Supervisor II, also
consult the Supervisor Controller manual, or Supervisor II Instruction manu-
al (for Supervisor II Deluxe models).

Operator should be familiar with all safety measures as described in the
Supervisor Controller™ or Supervisor II Instruction manuals (whichever per-
tains). 

Machines should be off-line and not running when making parameter
changes. Unexpected machine operation may occur.
