Handling the OCX 8800
System Considerations
Prior to installing your OCX 8800, 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 components, select mounting locations
and determine how each component will be placed in terms of available line
voltage, ambient temperatures, environmental considerations, convenience,
and serviceability. Figure 1-3 shows a typical system wiring for a system with
integral electronics. Figure 1-4 shows a typical system wiring for a system
with remote electronics. Simplified installations for the OCX 8800 are shown
in Figure 1-5 and Figure 1-6. Figure 1-7 shows the dimensions for the
optional sample tube support. Figure 1-8 shows the dimensions for the
optional in-situ filters. Figure 1-9 shows the optional panel mounted blowback.
A source of instrument air is required at the OCX 8800 for reference air,
dilution air, and eductor air. Since the OCX 8800 is equipped with an in-place
calibration feature, provision should be made for connecting test gas tanks to
the OCX 8800 when it is to be calibrated.
NOTE
The electronics module is designed to meet Type 4X and IP66 (when
reference air vents are routed to a dry area) and the electronic components
are rated to temperatures up to 185°F (85°C).
Retain packaging in which the unit arrived from the factory in case any
components are to be shipped to another site. This packaging has been
designed to protect the product.
It is important that printed circuit boards and integrated circuits are handled only when
adequate antistatic precautions have been taken to prevent possible equipment damage.
The OCX 8800 is designed for industrial application. Treat each component of the system
with care to avoid physical damage. The probe may contain components made from
ceramics, which are susceptible to shock when mishandled.
