possibility of mists, aerosols, oil, water, dust, or other
contaminates being drawn into the instrument. A line-
end filter
(P/N 275-0315)
should be attached to the
end of each sample intake line. General placement
guidelines are shown below, but air-flow dynamics
should also be considered (e.g., consider the effects of
exhaust fans which tend to draw target gas from the
space).
IMPORTANT:
DO NOT
block any of the zones.
Unused zones may be disabled by setting their length
parameter to zero feet in the
Zone Setup screen
Section 7.2., The Zone Setup Screen
).
Depending on type of use and location of lines, the
end-of-line water stop filter assembly can be used to
prohibit moisture from entering the intake lines.
Three (3) end-of-line water stop filters are supplied
with a standard unit. Place the end of the intake line
into the blue receiver of the end of line water stop and
tighten sufficiently.
Note that only filter assembly, either the line-end
filter or end-of-line water stop, should be used for
each line.
Please refer to the earlier section (
Suggested Location of Sampling Points
) to learn
more about where to locate the monitoring points.
3.2.6. Considerations
For maximum protection, the RLDS may be shut
down when a System Fault occurs. This might be
desired, for example, when the RLDS is used in wet
locations such as meat preparation rooms. When
water is pulled into the system, a System Fault will
occur, closing the fault relay located at the bottom of
the main control board. To turn power off to the
RLDS when this occurs, wire the fault relay into a
spare 16AI input. Route the power supply to the
RLDS through an 8RO output using the normally
closed contacts. Program the E2/Einstein to alarm the
fault input on a contact closure and turn on the 8RO
output when this occurs. This can be done using a
Digital Sensor Control application in the E2/Einstein.
Refer to the E2 Installation and Operation manual
(
P/N 026-1614
) for details on setting up a Digital
Sensor Control application.
