GETTING STARTED
1. Install the control as described on page 3.
2. Wire your control following the instructions on page 3 and drawing on page 4.
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 7) before making changes to the SECONDARY MENU (page 6). If
error messages occur, check the Diagnostic Error Messages on page 10 for help.
Take the example of a Model CT15011 that comes from the factory programmed 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 7. 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.
