TE-6300M Series Well Insertion Temperature Sensors Installation Instructions
2
Note:
The Johnson Controls® TE-6300W-101
thermowell contains thermal compound. The
TE-6300W-102 and TE6300W-110 do not contain
thermal compound. Add thermal compound
(F-1000-182, or equivalent) before inserting the probe
if the well does not include thermal compound. For
proper sensor function, mount the well so that any
condensation that forms drains out of the probe.
1.
If the thermowell is:
•
Direct Mount
(TE-63xAM-2), loosen the set
screw
•
Threaded
(TE-63x2M), screw the well adaptor
into the thermowell and loosen the well adaptor
set screw
2.
Insert the sensor probe into the thermowell until it
touches the bottom.
3.
Pull back the probe approximately 1/8 in. (3 mm)
and then tighten the set screw.
4.
Wire the sensor to the controller.
5.
Reposition the cover and tighten the cover screws.
Wiring
For 1k ohm nickel temperature sensors, wire resistance can
cause about 1F° (0.56C°) of error for every 250 ft (76 m) run
of 18 AWG (1.0 mm diameter) wire, or every 100 ft (31 m) run
of 22 AWG (0.6 mm diameter) wire.
For 1k ohm platinum temperature sensors, wire resistance
can cause about 1F
(0.56C
) of error for every 150 ft (46 m)
run of 18 AWG (1.0 mm diameter) wire, or every 50 ft (15 m)
run of 22 AWG (0.6 mm diameter) wire. To minimize error
due to field wiring, limit total resistance of all nickel
temperature sensor wiring to 3 ohms, and all platinum
temperature sensor wiring to 2 ohms.The 2.2k and 10k ohm
thermistor applications permit wiring to be relatively long
before wire resistance adds significantly to total resistance
measured at the controller. As a general rule, a 150 ft (46 m)
two-wire 18 AWG (1.0 mm diameter) run contributes 2 ohms
of error, or less than 1F
(0.56C
) error over the sensor
operating temperature range.
Refer to the appropriate controller documentation for
recommended sensor wiring. Secure the wiring bushing or
conduit only to the temperature sensor base. See Table 1 for
an explanation of the lead wiring color convention

CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte
risquent d'endommager
irrémédiablement l'équipement.
IMPORTANT:
Use copper conductors only. Make
all wiring connections in accordance with local,
national, and regional regulations. Do not exceed
the TE-6300M Series Well Insertion Temperature
Sensor’s electrical ratings.
