How To Setup The Series 945
Setting up the Series 945 is a simple process. First configure the 945's features to
your application in the Setup Menu, and then enter values in the Operating Menu.
Use the MODE key to move through the menus and the UP/DOWN keys to select
data.
At this point, enter the Calibration menu by pressing the UP/DOWN keys simulta-
neously for 3 seconds. Selecting US or SI under the dFL parameter determines the
following: If selected as US, rate, reset, °F and proportional band in degrees will
appear. If selected as SI, integral, derivative, °C and proportional band in % of span
will appear. See Appendix II to change this parameter.
How to Set the DIP Switch
The Watlow Series 945 has a Dual In-line Package (DIP) switch inside the control on
the A007-1954 circuit board (middle board). The location of the board and switches
appear below. The switches are clearly numbered. When Switch #1 is ON, the Setup
parameters can be viewed but not changed. Switch #2 is not used. The factory
default is OFF.
Entering the Setup Menu
Enter the Setup Menu by pressing the UP/DOWN keys simultaneously for 3 seconds.
The lower display shows the LOC parameter, and the upper display shows its current
level. All keys are inactive until you release both keys. You can reach the LOC
parameter from anywhere.
You will not see all parameters in this menu, depending on the unit's configuration and
model number. After stepping through the menu it returns to the control set point
parameter under the Operation menu.
