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.
