5. Connect stainless steel tubing from manifold to orifice tap valves. For
best measurement, use large bore, short, equal length gage lines
with a downward slope to taps (at least 1" per 3 feet). With the
manifold equalized to avoid damaging the device's transducer, apply
pressure to the manifold and check for leaks.
6. Assemble and install the RTD using the instructions included with the
RTD kit. Wire RTD to unit per local codes. See page 7 for additional
information. See also Figures 6 & 9 for wiring terminations.
Installing the 6270 Optional Equipment Unit
The 6270 OEU (Optional Equipment Unit) contains the power supply,
battery and any optional communication's equipment. If the user is
providing their own power and/or communications and not using the
Optional Equipment Unit go to Step 10.
The OEU can only be installed in a Division 2 or General Purpose
area. All wiring between the 6200EX which can be in a Div 1 area
and the OEU must be done per local codes. See pages 12 & 13 for
wiring terminations.
7. Mount the OEU on a 2" pipe or flat surface using the supplied
installation kit. If a solar panel is used and is to be pipe mounted, use
a pipe long enough or be able to add a coupling and pipe joint on top
of the existing pipe
