Temperature Controller Set-up
The XDS Process Analytics Instrument contains a temperature controller to maintain internal
temperature of the enclosure. This is normally set to 38.0 degrees C (100.4 degrees F).
Temperature is read in degrees C.
A temperature-sensing device is embedded in
the instrument cabinet, and this is used as a
method to control the internal temperature.
This control maintains internal temperature by
cycling the heaters, air conditioner (if so
equipped), Vortec cooler (if so equipped) and
the external fan to drive cooling air over the
heat sink.
An internal fan is used to circulate air inside
the enclosure. This assures that all
components are at a consistent operating
temperature.
The upper number (red LED) indicates actual
enclosure temperature. The lower number (green
LED) indicates the set-point value.
This photo shows the set point as 38.0 degrees C, and the actual enclosure temperature as 38.0
degrees C, equal to the set point. This indicates a stable temperature situation.
Follow this procedure to set instrument temperature:
With the instrument powered on, press the INDEX button until the SP1 Indicator
is lit. The green LED display will show “SP1”. The set point is shown in the Red
LED display, and is adjusted using the arrow buttons.
INDEX
Press the UP button to reach the desired set point for SP1. Temperature reads in
degrees Celsius.
UP
If the temperature setting is too high for SP1, use the down button to lower the
set point.
DOWN
When the set point is correct, press the ENTER button. The temperature will be
controlled by the instrument. The display will reset to the normal display after
about 30 seconds, after taking several sample temperature readings.
