5.Field replaceable cell, heater, thermo- couple, diffuser, and PC boards.

6.The Hazardous Area Oxymitter 4000 is constructed of rugged 316L stainless steel for all wetted parts.

7.The electronics is adaptable for line voltages from 90-250 VAC; therefore, no configuration is necessary.

8.The Hazardous Area Oxymitter 4000 membrane keypad is available in five languages: English, French, German, Italian, and Spanish.

9.An operator can calibrate and com- municate with the Hazardous Area Oxymitter 4000 in one of three ways:

Accessing the probe keypad requires opening the electronics housing. Opening the electronic housing will cause the loss of ALL hazardous per- mits. Opening the electronics housing in hazardous areas may cause an ex- plosion resulting in loss of property, severe personal injury, or death. It may be required to get a hot work permit from your company safety offi- cer before opening the electronic housing.

(a)Membrane Keypad. The mem- brane keypad, housed within the right side of the electronics hous- ing, provides fault indication by way of flashing LEDs. Calibration can be performed from the mem- brane keypad.

(b)LOI. The optional LOI takes the place of the membrane keypad and allows local communication with the electronics. Refer to Sec- tion 4 for more information.

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.

(c)Optional HART Interface. The Hazardous Area Oxymitter 4000’s 4-20 mA output line transmits an analog signal proportional to the oxygen level. The HART output is superimposed on the 4-20 mA out- put signal. This information can be accessed through the following:

1Rosemount Model 275/375 Handheld Communicator - The handheld communicator requires Device Description (DD) software specific to the Hazardous Area Oxymitter 4000. The DD software will be supplied with many Model 275/375 units but can also be programmed into existing units at most Fisher- Rosemount service offices. See Section 7, HART/AMS, for additional information.

2Personal Computer (PC) - The use of a personal com- puter requires AMS software available from Fisher Rosemount.

3Selected Distributed Control Systems - The use of distrib- uted control systems requires input/output (I/O) hardware and AMS software which permit HART communica- tions.
