Hazardous Area Oxymitter 4000
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.

Instruction Manual
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:
1 Rosemount 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.
2 Personal Computer (PC) -
The use of a personal com-
puter requires AMS software
available from Fisher
Rosemount.
3 Selected Distributed Control
Systems - The use of distrib-
uted control systems requires
input/output (I/O) hardware
and AMS software which
permit HART communica-
tions.
