Teledyne 3000ZA-3X Installing the Zirconium Oxide Sensors, Testing the System

Installation 3000ZA-3X

The data is status information, in digital form, updated every two seconds. Status is reported in the following order:

∙The concentration in ppm or percent

∙The range in use (HI, MED, LO)

∙The span of the range (0-100 ppm, etc)

∙Which alarms—if any—are disabled (AL–x DISABLED)

∙Which alarms—if any—are tripped (AL–x ON).

3.4Installing the Zirconium Oxide Sensors

If the ZrO2 sensors are not installed in the cell block when the instrument is shipped, they must be installed before the analyzer is placed in service. If they are not installed, the sensors will be packaged with their Teledyne Analytical Instruments part number marked on the bag.

When the ZrO2 sensor needs to be installed or replaced, follow the procedures in Section 5.2.

If sensors were installed at the factory, remove the cover, by loosening the eight screws that secure it and check that each sensor is firm in its respective socket.

3.5 Testing the System

Before applying power to the instrument:

∙Check the integrity and accuracy of the gas connections. Make sure there are no leaks.

∙Check the integrity and accuracy of the electrical connections. Make sure there are no exposed conductors.

∙Check that inlet sample pressure is within the accepted range (see Section 3.3.1).

∙Power up the system, and test it by repeating the Self- Diagnostic Test as described in Chapter 4, Section 4.3.5.
