7.0 SYSTEM PROGRAMMING– GENERAL
System Configuration: The PDC controller is completely configurable by the end user. Reference the following pages for more details
regarding the configuration of a system.
Programming: Any changes in the system operation can be made quickly and easily by means of the push-button programming feature. Three
small, momentary push-buttons can be located on the upper left corner of the circuit board. These push-buttons can be used to enter a large
selection of four digit codes to access a wide range of system functions and features. For more detailed information on system programming,
consult the programming section of this manual.
The PDC controller has an extensive menu system that allows the user maximum flexibility, through programming, to achieve a wide range of
system functions. Important: Please carefully read through the programming section before attempting to make programming changes.
The system menu structure is broken into three major sections. “Input Control”, “Output Control” “Other Codes”. Input control allows the user to
program all the desired parameters for the sensor input channels. Output control allows the user to program all the desired parameters for the
relay outputs for controlling other devices. Other codes provide the user with other functions to customize their system.
The following table indicates available programmable functions and the input codes for each. Detailed descriptions for each function code can
be found on following pages.
NOTE: Holding down a button for more than 2 seconds will allow the user to scroll very quickly.
WARNING: CHANGING PROGRAMMING CODES MAY RESULT IN SYSTEM PROBLEMS. DO NOT ATTEMPT WITHOUT CONSULTING
THE FACTORY.
