General
This section will explain the front panel displays and the operation of the front panel soft-buttons. This section is
intended as an aid to the everyday operator of the PCC-IV controller.
The PCC-IV is a general purpose, software configurable, microprocessor based controller. Typical applications:
•
High school heating plant firing rate controller, with time of day clock, start time logic and outside
air temperature reset
•
Multiple burner, high pressure steam boiler fuel flow and air flow controller
•
Boiler furnace pressure (i.e. draft) controller
•
Electric generator steam turbine throttle valve controller
•
Waste water pH controller
•
Pump and Fan variable speed drive flow/pressure controller
•
Batch reactor temperature controller
•
Paper stock consistency controller
•
Chemical additive ratio blending controller
•
Heat treating temperature controller
The same physical PCC-IV controller hardware is used in every case. What differentiates one controller from
another is the application-specific blockware (i.e., control strategy software) in the memory of the PCC-IV.
By design, the PCC-IV is exceedingly flexible, and very adaptable. For convenience, this section will use specific
examples to explain how to operate the PCC-IV. However, the reader should remember that
each PCC-IV will be
programmed differently to suit the needs of an application. For this reason, one must consult the
documentation for the blockware loaded in the memory of your specific PCC and become familiar with your
installation before attempting to operate the PCC-IV controller.
