Powering up the Analyzer
After all the preparation work is done and the installation
and wiring have been checked, turn on the analyzer and wait
for at least 30 minutes (or until Cell T Not Stable message
disappears). This will allow the analyzer to reach its operating
temperature of +50°C and protect it from any condensation
forming in the sensor.
There is no power switch on the 501 Analyzer. It is turned on automatically once a 24
V DC power source is applied. After the analyzer is powered up, the display will be
illuminated. The analyzer takes up to 5 seconds to initialize, and during this period will
display the product type and firmware version number. The transmitter version (XTP501-
GP2) has a power interrupt button for use when connecting the optional remote display,
approximately 10 minutes will be required for stabilization after powering back on.

Once initialized, the analyzer will show the Main Page which displays the O2 concentration.
During warm-up (less than 25 minutes) a heating symbol will flash in the top right-
hand corner of the page. This symbol will remain until the temperature has stabilized
for a minimum of 5 minutes. The analyzer will be ready for use within 30 minutes from
power-up.
