Hazardous Area Oxymitter 4000

(d)Optional IMPS 4000. The Pro- grammable Logic Controller (PLC) in the IMPS 4000 provides fault indications using flashing LEDs and LCD display messages. Refer to the IMPS 4000 Intelligent Multi- probe Test Gas Sequencer manual for more information.

10.The optional Rosemount 751 remote mounted LCD display panel is loop- driven by the 4-20 mA output signal representing the O2 percentage.

e.Handling the Hazardous Area 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 Hazardous Area Oxymitter 4000 is designed for industrial applications. Treat each component 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 Hazardous Area 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 1-5shows a typical system wiring.

A typical system installation with integral electronics is illustrated in Figure 1-6.A typical system installation with remote elec- tronics is illustrated in Figure 1-7.

The HART option is not protected by energy limiting barriers. It must not be interfaced from within the hazardous area. The 4-20 mA cables should be routed and the connections made out- side the hazardous area. Note that this is the case even when using the in- trinsically safe version of the handheld communicator.
