Hazardous Area Oxymitter 4000

Instruction Manual

IB-106-340C Rev. 4.1

July 2004

1

A source of instrument air is optional at the Hazardous Area Oxymitter 4000 for reference air use. Since the unit can be equipped with an in-place calibration fea- ture, provisions can be made to perma- nently connect calibration gas bottles to the Hazardous Area 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 and solenoid valves in the IMPS 4000 or SPS 4000.

NOTE

1-4 SPS 4000 (OPTIONAL)

If using an SPS 4000 with a Hazardous Area Oxymitter 4000, the SPS 4000 sequencer must be installed in a non-hazardous, explosive-free environment.

For further SPS 4000 information, refer to the SPS 4000 Single Probe Autocalibration Sequencer Instruction Bulletin.

1-5 MODEL 751 REMOTE POWDERED LOOP LCD DISPLAY

The display, Figure 1-8,provides a simple, economical means to obtain accurate, reliable, and remote indication of important process vari- ables. This display operates on the 4-20 mA line from the Hazardous Area Oxymitter 4000.

Refer to Model 751 remote powered loop LCD manual for calibration and wiring.

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

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

Retain the original packaging for the Hazardous Area Oxymitter 4000, in case the components are to be shipped to another site. This packag- ing is designed to protect the product.

1-3 IMPS 4000 (OPTIONAL)

If using an IMPS 4000 with a Hazardous Area Oxymitter 4000, the IMPS 4000 sequencer must be installed in a non-hazardous, explosive-free environment.

For further IMPS 4000 information, refer to the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer Instruction Bulletin.
