Dwyer 32A - Manual (Page 3)

GETTING STARTED
1. Install the control as described on page 4.
2. Wire your control following the instructions on page 5. If you are using a two-wire transmitter as an
input, see the drawing and instructions on page 7. Option wiring instructions are on page 6. Option
descriptions are on page 4, and specific instructions start on page 15.
3. Most controls do not need many (if any) program changes to work on your process. For best results
when programming changes are necessary, make all the necessary changes in the Secure Menu
(page 24) before making changes to the Secondary Menu (page 18). If error messages occur,
check the Diagnostic Error Messages on page 33 and 34 for help.
Take the example of a Model 32A010 that comes from the factory programmed for type J thermocou-
ples. 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 Unit. 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 60 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.
If you want to use Self Tune ® , Auto/Manual, or the Ramp/Soak Programmer features, see the special
sections on these items. Page numbers for these are in the Contents section on the previous page.
