Mounting and Wiring the Sensors
6.1. The Dewpoint Sensor
6.1.1. Placement
In order for the Control Link ACC to function
properly, the dewpoint sensor
must
be placed where
it can measure the dewpoint of the air
outside
the
case. Mount the sensor underneath the top side of the
case in the area just above the top of the doors
(
Figure 6-1
).
A 0.25” x 0.25” (6.35 mm x 6.35 mm) notch in the
edge of the metal frame behind the sensor may be re-
quired for the wires connecting the dewpoint sensor to
the Control Link ACC. DO NOT let any RTV sealants
touch the sensor element and keep the sensor element
as far as possible from RTV-sealed areas.
Do NOT mount the dewpoint sensor near the
bottom of the case or any place where cold air from
the case can affect the sensor reading. Avoid
mounting the sensor in an area with excessive water
spray or moisture, extremely dirty environments, near
heat sources, or in the direct path of HVAC returns.
Secure the sensor to the mounting location with the
two included screws (
P/N 031-6005
) as shown in
Figure 6-2
. Emerson recommends using pilot holes
for the screws. Tighten the screws just enough to
secure the sensor without warping the sensor housing.
