The various parameters are arranged in different groups, called PAGES, depending upon the functions they represent. Each
group is assigned a unique numeric value, called PAGE NUMBER, for its access.
The parameters are always presented in a fixed format: The Lower Readout displays the parameter prompt (Identification
Name) and the Upper Readout displays the set value. The parameters appear in the same sequence as listed in their
respective sections.
SET-UP MODE
The Set-up Mode allows the user to view and modify the parameter values. Follow the steps below for setting the parameter
values:
1. Press and release PAGE key. The Lower Readout shows PAGE and the Upper Readout shows page number 0. Refer
Figure 3.1.
2. Use UP / DOWN keys to set the desired PAGE NUMBER.
3. Press and release ENTER key. The Lower Readout shows the prompt for the first parameter listed in the set PAGE and
the Upper Readout shows its current value. (If the entered PAGE NUMBER is invalid (contains no parameter list or any
associated function), the controller reverts to the MAIN Display Mode.
4. Press and release the ENTER key until the prompt for the required parameter appears on the Lower Readout. (The last
parameter in the list rolls back to the first parameter).
5. Use UP / DOWN keys to adjust the parameter value. (The display flashes if UP key is pressed after reaching the maximum
value or DOWN key is pressed after reaching the minimum value).
6. Press and release the ENTER key. The new value gets stored in the controller’s non-volatile memory and the next
parameter in the list is displayed.
The Figure 3.1 illustrates the example of altering the value for the parameter ‘Input Type’.

Notes
1. Each page contains a fixed list of parameters that are presented in a pre-determined sequence. Note however that
availability of a few parameters, called Conditional Parameters, depend upon the settings for some other parameters. For
example, the parameter ‘Control Hysteresis’ for Output-1 is available only if, the set value for the parameter ‘Control
Action’ is ‘On-Off’.
2. To exit the set-up mode and return to the MAIN Display Mode, press and release PAGE key.
3. If no key is pressed for approximately 30 seconds, the set-up mode times out and reverts to the MAIN Display Mode.
