If your connection is not working properly, check the following conditions:
A. Verify complete and tight cable connections between the Thermo Fisher
Scientific unit and the PC.
B. Verify that power has been supplied to the unit and temperature controller
before starting the software program.
C. Verify the configuration values in the controller, listed in the
Table 2.

Decimal Point Adjustment
If the decimal point on the PC display of the controller does not match the
controller display, you can make an adjustment to correct this:
1. From the Configuration Mode (available through the '”file” drop down while in
the Run time Mode), select the “Variables List” icon, represented by a page
with lines on it.
2. Select the controller model number and select “Properties” button. The
“Add/Rename Instrument” box appears.
3. In the Address window, highlight the middle digit (usually at), and change to '0'
(zero).
4. Click the “Rename Only” button. Close the “Variables” box (click on 'X' in
corner of smaller box).
5. Select the “Enter Runtime” icon to see the results of the change.
UT350 Control (BF51634C, BC models only)
BF51634C and BF51634BC models use the single setpoint UT350 controller. For
complete controller instructions, refer to the separate UT350 manual provided with
your furnace.
The temperature controller is configured and tuned at the factory to function well
for most applications. Occasionally, it may be advisable to configure the
temperature controller differently to suit a particular working environment or
process.
