e. Handling the Oxymitter 4000

It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to pre- vent possible equipment damage.

The Oxymitter 4000 is designed for in- dustrial applications. Treat each com- ponent of the system with care to avoid physical damage. Some probe components are made from ceramics, which are susceptible to shock when mishandled.

f.System Considerations

Prior to installing your Oxymitter 4000, make sure you have all the components necessary to make the system installation. Ensure all the components are properly in- tegrated to make the system functional.

After verifying that you have all the compo- nents, select mounting locations and deter- mine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considera- tions, convenience, and serviceability. Figure 1-3shows a typical system wiring. A

typical system installation is illustrated in Figure 1-4.

A source of instrument air is optional at the Oxymitter 4000 for reference air use. Since the unit is equipped with an in-place cali- bration feature, provisions can be made to permanently connect calibration gas tanks to the Oxymitter 4000.

If the calibration gas bottles will be perma- nently connected, a check valve is required next to the calibration fittings on the integral electronics.

This check valve is to prevent breathing of the calibration gas line and subsequent flue gas condensation and corrosion. The check valve is in addition to the stop valve in the calibration gas kit or the solenoid valves in the IMPS 4000 or SPS 4000.

NOTE

The integral electronics is rated NEMA 4X (IP66) and is capable of operation at temperatures up to 149°F (65°C).

Retain the packaging in which the Oxymitter 4000 arrived from the fac- tory in case any components are to be shipped to another site. This packag- ing has been designed to protect the product.
