6 Controller Operation

This chapter discusses in detail how to operate the dry-well temperature controller

using the front control panel. Using the front panel key-switches and LED display the

user may monitor the well temperature, set the temperature set-point in degrees C or F,

monitor the heater output power, adjust the controller proportional band, and program

the calibration parameters, operating parameters, and serial interface conguration.

Operation of the functions and parameters are shown in the owchart in Figure 5 on

page 21 This chart may be copied for reference.

In the following discussion a button with the word SET or EXIT inside or u, and

d, indicates the panel button while the dotted box indicates the display reading.

Explanations of the button or display reading are to the right of each button or display

value.

6.1 Well Temperature

The digital LED display on the front panel allows direct viewing of the actual well

temperature. This temperature value is normally shown on the display. The units, C or

F, of the temperature value are displayed at the right. For example,

100.0 C WelltemperatureindegreesCelsius

The temperature display function may be accessed from any other function by pressing

and holding the “EXIT” button.

6.2 Temperature Set-point

The temperature set-point can be set to any value within the range and with resolution

as given in the specications. Be careful not to exceed the safe upper temperature limit

of any device inserted into the well.

Setting the temperature involves selecting the set-point memory and adjusting the set-

point value.

6.2.1 Programmable Set-points

The controller stores 8 set-point temperatures in memory. The set-points can be

quickly recalled to conveniently set the calibrator to a previously programmed

temperature set-point.

To set the temperature, rst select the set-point memory. This function is accessed

from the temperature display function by pressing “SET”. The number of the set-

point memory currently being used is shown at the left on the display followed by the

current set-point value.
