INITIAL CONFIGURATION START-UP
CONTROLLER POWER-UP
Upon applying power, the controller delays input indication and control action for five seconds to perform several self-diagnostic tests and to display basic controller information. Initially, the controller illuminates both displays and all annunciators to verify that all display elements are functioning. The controller then displays the programmed input sensor type in the main (top) display and the revision number of the controller’s operating system software in the secondary (bottom) display. The controller checks for correct internal operation and displays an error message (E-xx) if an internal fault is detected. (See Troubleshooting, page 73, for further information).
Upon completion of this sequence, the controller begins displaying the input value and updating the outputs based upon the control calculation.
PARAMETER CONFIGURATION OVERVIEW
The controller is programmed with certain parameter settings from the factory. Factory settings are listed in parentheses in the various Configuration of Parameters tables. In many cases, these settings must be changed to the particulars of the application before proper operation can be started.
The controller is typically in the Normal Display Mode. When changes to parameter configurations are needed, the P button is pressed. From the factory, the controller will enter directly into the Unprotected Parameter Mode.
Continue to press the P button until CnFP appears in the bottom display. At this time, press the Up arrow button and 1-In will appear in the bottom display. This will be the Configuration Parameter Mode. This programming flow is shown in the Front Panel Programming Chart. (If at any time during front panel programming the D button is pressed, the controller will return to the Normal
Display Mode and the programming can be started over.)
In the Configuration Parameter Mode, the Up or Down arrow buttons can be pressed to move to the desired Parameter Module. The P button is then pressed to enter into that module. The main (top) display will be the parameter and the secondary (bottom) display will be the parameter value. The Up or
Down arrow buttons are used to change the desired parameter value and the P button enters the new value and moves to the next parameter.
The Setpoint value (lower display) is changed with the Up or Down arrow buttons when it is selected in the Normal Display Mode.

PARAMETER CONFIGURATION BASIC START-UP
For basic start-up, it is important to verify or change Input Parameter
Module (1-IN) parameters tYPE and SCAL, and Output Parameter Module
(2-OP) parameter OPAC. For alarm and heat/cool set-up, it is important to verify or change Alarms Parameter Module (4-AL) parameters ACt1, AL-1,
ACt2 and AL-2.
If the above Input Parameters or the input wiring connections are not correct, then the main (top) display may display an error message or incorrect value. Verify the input programming and wiring. (If incorrect display continues refer to Troubleshooting, page 73.) All other parameter configurations are important but will not prevent the controller from showing a correct display.
PARAMETER CONFIGURATION FOR SERIAL START-UP
The parameter settings can be changed by the front panel buttons or by serial communications using PC Windows based SFCRM software. The controller must have optional RS485 communications. An RS485 to RS232 converter is available from Red Lion Controls for RS232 interfaces. For serial communications set-up, it is important to check serial wiring and verify or change Serial Parameter Module (6-SC) parameters bAUd, ConF,s and
Addr. (See Serial Communications Interface, page 58, for more details.)
CONTROL START-UP
After verifying proper programming and system start-up, a controlling method needs to be configured. For Manual Control or open loop, where the control does not work from the setpoint or process feedback, see Manual
Control, page 47. For On / Off Control, set Proportional Band Prop to 0.0% and see On / Off Control, page 48. The controller comes with factory setting for PID Control. However, for optimum PID Control, several options exist for configuring Proportional Band, Integral Time, and Derivative Time parameters for specific applications.
a. Use controller’s built-in Auto-Tune feature (See Auto-Tune For PID
Control, page 51).
b. Use a manual tuning technique (See Manual Tuning For PID Control, page 56).
c. Use a third party tuning software package.
d. Use values based on control loop experience, calculated values or values from a similar process or previous controller.
