Note: Configuration numbers not listed are not used in this application. These items may appear when loading
configuration software to the controller but changes will not be recognized by the controller programming.
4.2.2 Operational Software (Cd Function Codes)
The operational software is the actual operation programming of the controller which activates or deactivates
components in accordance with current unit operating conditions and selected modes of operation.
The programming is divided into function codes. Some of the codes are read only, while the remaining codes may
be user configured. The value of the user configurable codes can be assigned in accordance with user desired
mode of operation. A list of the function codes is described in Table 4–4.
General Notes on Function Code Navigation
1. Press the CODE SELECT key on the keypad. Then, use the Arrow keys to navigate through the function
codes (Cd) in the left display. The right display will show the respective data. If the right display shows
dashes “-----”, then this is an optional code not available to the system.
2. Press the ENTER key to navigate into the menu of the selected Cd code. Pressing the ENTER key will
cause the present selected value to be displayed for 5 seconds, or until the user selects a different value. If
additional time is required, pressing the ENTER key will extend the display time to 30 seconds.
3. Pressing CODE SELECT key in a selection menu cancels the current selection activity and ascends back
up to the next higher selection menu.
4. If the operator does not press any key for five seconds the interface reverts to normal system display and
the current selection menu is cancelled, but any previously committed changes are retained.
