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 integrated 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 1-6shows a typical system wiring.

A typical system installation for an Oxymitter 4000 with integral electronics is shown in Figure 1-7.A typical system installation for an Oxymitter 4000 with remote electronics is shown in Figure 1-8.

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 bottles 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 electronics is rated NEMA 4X (IP66) and is capable of operation at temperatures up to 185°F (85°C).

The optional LOI is also rated for op- eration at temperatures up to 185°F (85°C). The infrared keypad function- ality will degrade at temperatures above 158°F (70°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.
