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 configuration.
Operation of the functions and parameters are shown in the flowchart 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 specifications. 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, first 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.
