CONFIGURATION PARAMETER MODE
The Configuration Parameter Mode is accessed by pressing the Up button from CnFP in the Unprotected Parameter Mode. While in this mode, the various Configuration Modules can be displayed by pressing the Up or Down buttons. The process value (after initial setup) will be displayed in the main
(top) display. The Configuration Module will appear alternating with CnFP in the secondary (bottom) display.
To access a Configuration Module, press the P button when the desired
Configuration Module is displayed. The parameters of that Configuration
Module can be accessed by pressing the P button. (The module’s parameters are listed in the appropriate Configuration Module table in this section with configuration parameter explanations beginning on page 31.) To modify ranges and units, use the Up or Down arrows while the parameter is displayed.
The controller responds to the new values after the P button is pressed, however, the change is not committed to permanent memory until the controller is returned to the Normal Display Mode. If power loss occurred before returning to the Normal Display Mode, the new values must be entered again. Whenever the D button is pressed, End will momentarily appear and the controller will return to the Normal Display Mode. At the end of each module, the controller will go to CnFP no. Pressing the Up or Down arrows will continue in Configuration Parameter Mode and pressing the P will return to the Normal Display Mode.
Unless specified, the parameters, ranges, units and factory settings are the same for T48 and P48 controllers. Parameters that are model number or program dependent will only be displayed when the appropriate options are installed or programmed. Some parameters are accessible but may not be applicable for the chosen output control mode type.
