f. 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 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 1-6 shows a typical system wiring.
A typical system installation for an Oxymitter
4000 with integral electronics is shown in
Figure 1-7. A typical system installation for
an Oxymitter 4000 with remote electronics
is shown in Figure 1-8.
A source of instrument air is optional at the
Oxymitter 4000 for reference air use. Since
the unit is equipped with an in-place cali-
bration feature, provisions can be made to
permanently connect calibration gas bottles
to the 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 or the solenoid valves in
the IMPS 4000 or SPS 4000.
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 op-
eration at temperatures up to 185°F
(85°C). The infrared keypad function-
ality will degrade at temperatures
above 158°F (70°C).
Retain the packaging in which the
Oxymitter 4000 arrived from the fac-
tory in case any components are to be
shipped to another site. This packag-
ing has been designed to protect the
product.
