Note: Hand tighten only - do not overtighten.
1. Determine the sensor mounting location on the duct (predetermine the kn ockout hole
location for routing of conduit). The sensing element is located within 1 inch of the end of
the sensing probe, and it should be in the air stream at a location that is typical of the
temperature requiring sensing. Approximately 3" of length adjustment is available.
2. Use the mounting flange supplied as a template (or refer to Figure-1 for duct mounting dimensions) for mounting hole location.
3. Mount the sensor to the duct using the two #10 x 3/4" sheet metal screws provided.

Note: The AT-215 bulb well should be filled with a temperature conductive grease prior to
element insertion, for optimum medium temperature sensing.

1. Thread the sensor into AT-215 bulb well that has been installed in a liquid li ne or ta nk (Figure-2).
1. Determine the sensor mounting location on the duct. The sensing element is located

TS-672x-851 requires AT-225 bulb well to be purchased separately (Figure-4). Thread the
sensor into AT 225 bulb well that has been installed in a liquid line or tank.
Note: The AT-225 bulb well should be filled with a temperature conductive grease prior to
element insertion, for optimum medium temperature sensing.
Figure-4 TS-672x-851 and TS-672x-853 Immersion Mounting.
Foam insulation tape should be taped over the sensor (Figure-5). Extend insulation beyond
the ends of the sensor.
Secure sensor and foam insulation tape to pipe with wire tie (factory supplied) or metal hose
clamp (not included).
Do not tighten clamp or wire tie to the point of distorting the sensor. Overtightening
fasteners will cause a shift in sensed temperature.

When a duct sensor is being replaced at a location where an existing mounting hole size
exceeds the coverage of the adaptor flange, use the existing mounting plate as follows:
1. Remove the existing unit from the duct. Note location of the unit’s conduit h ole.
2. Remove (and set aside for later use) the conduit nut securing the mounting plate to the sensor.
3. Remove the mounting plate from the old sensor.
4. Place the mounting plate on the new sensor and secure with the conduit nut removed from the old sensor. Do not include the plastic adaptor flange.
5. When mounting the sensor to the duct, be sure the conduit hole is located appropriately .

WIRING
C A U T I O N
Two conductor twisted wires (six turns per foot). Class II, low voltage, are suitable for the
sensor leads except as stated below.
Shielded cable must be used when it is necessary to install the sensor lead in the same
conduit with power wiring, or when it is known that high RFI/EMI generating devices are
near. System Ground the shield per Schneider Electric NETWORK 8000 specifications. Do
not use a sensor enclosure as a junction box for other control circuits.
It is generally advisable to use flexible conduit to connect enclosure to rigid conduit.
Restrict element lead to shortest length practical (see Table-5).

Regular maintenance of the total system is needed to assure sustained optimum
performance. Sensors should be periodically inspected for dirt or blockage of air over the
elements.
These sensors are not field repairable. Replace the sensor with a functional unit.
