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 components, select mounting locations and determine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considerations, convenience, and serviceability.

Figure 1-7shows a typical system wiring.

A typical system installation for an Oxymitter 4000 with integral electronics is shown in Figure 1-8.A typical system installation for an Oxymitter 4000 with remote electronics is shown in Figure 1-9.

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

If the calibration gas bottles will be permanently 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 4001B.

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 operation at temperatures up to 185°F (85°C). The infrared keypad functionality will degrade at temperatures above 158°F (70°C).

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