Mounting
The following ambient operating conditions apply:
•
Temperature: -10 to 60°C (14 to 140°F)
•
Humidity: 10 to 90% Relative Humidity (RH),
noncondensing; 29°C (85°F) maximum dew point
Note:
The discharge air sensor is shock and vibration
resistant; however, be careful not to drop the unit or
mount it where it could be exposed to excessive
vibration.
To mount the discharge air sensor:
1.
Drill a 10 mm (3/8 in.) diameter hole in the duct at
the desired mounting location.
2.
Insert the temperature probe into the drilled hole.
3.
Secure the discharge air sensor to the duct using
two No. 6 self-drilling sheet metal screws included
with the unit.
Wiring
If the NS Series Network Discharge Air Sensor is used
in an application requiring multiple discharge air
sensors, each with a unique DIP switch address, set
the DIP switches before wiring the unit. Otherwise,
proceed directly to Step 5.
1.
Loosen (but do not remove) the two cover-holding
screws using a 6 mm (1/4 in.) blade screwdriver or
a 6 mm (1/4 in.) nut driver.
2.
Remove the cover from the discharge air sensor.
3.
See Figure 1 and set the DIP switch block on the
discharge air sensor circuit board to the desired
DIP switch address.
Note:
Table 1 lists the available DIP switch addresses
and the DIP switch settings required to obtain them.
4.
Reinstall the cover on the discharge air sensor and
tighten the two cover-holding screws to secure it in
place.
5.
Wire the discharge air sensor to the SA Bus screw
terminal block as illustrated in Figure 2.
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when this equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference, in which case
the user will be required to correct the interference
at his/her own expense.
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte
toutes les exigences du Règlement sur le matériel
brouilleur du Canada.
