GETTING STARTED
1. Install the control as described on page 4.
2. Wire your control following the instructions on page 4 and drawing on
page 5.
3. Most controls do not need many (if any) program changes to work on
your process. For best results if programming changes are necessary,
make all the necessary changes in the Secure Menu (page 10) before
making changes to the Secondary Menu (page 8). If error messages
occur, check the Diagnostic Error Messages on page 15 for help.
Take the example of a Model 25011 that comes from the factory pro-
grammed for type J thermocouples. Suppose for this example you wish to
change the input to type K and limit the set point range between 0° and
1000° C.
First, enter the Secure menu as instructed on page 5. Press the INDEX key
until the display shows Inp and press the DOWN ARROW until the display
shows CA. Don't forget to press the ENTER key to retain your setting.
Next, press the INDEX key to display F-C. Press the DOWN ARROW until
the display shows C. Press ENTER.
Next, press the INDEX key until SPL is displayed (pass the dPt and InPt
selections). Press the UP ARROW until the display shows 0. Press
ENTER.
Finally, press INDEX key to display SPH. Press the DOWN ARROW until
the display shows 1000. Press ENTER.
The necessary program changes are now complete. After 30 seconds the
display will switch back to the temperature reading. If you want to return
faster, press the UP ARROW and ENTER keys (at the same time) and then
press the DOWN ARROW and INDEX keys ( again at the same time). This
will 'back out' of the menu and immediately display the temperature reading.
