Wiring
For 1k ohm nickel temperature sensors, wire
resistance can cause approximately 1F° (0.56C°) of
error for every 250 ft (76 m) run of 18 AWG wire, or
every 100 ft (31 m) run of 22 AWG wire. For 1k ohm
platinum temperature sensors, wire resistance can
cause approximately 1F° (0.56C°) of error for every
150 ft (46 m) run of 18 AWG wire, or every 50 ft (15 m)
run of 22 AWG wire. To minimize error due to field
wiring, limit the total resistance of all nickel temperature
sensor wiring to 3 ohms, and all 1k ohm platinum
temperature sensor wiring to 2 ohms.
To minimize wiring error in applications using 100 ohm
platinum equivalent sensors, use the TQ-6000-1, 4
to 20 mA transmitter. Using a 4 wire (Kelvin)
connection can also eliminate wiring error.
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 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. See Table 2 for an
explanation of the lead wiring color convention.
Series-Parallel Wiring
To wire a duct averaging sensor, or another model in
series-parallel configuration, see Figure 11.
Note: Always use sensors of the same value and type
throughout the network.
Repair Information
If the TE-6300P Series Temperature Sensor fails to
operate within its specifications, refer to the
TE-6300 Series Temperature Sensor Product Bulletin
(LIT-216320) for a list of repair parts available.

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.
IMPORTANT: Use copper conductors only. Make
all wiring connections in accordance with local,
national, and regional regulations. Do not exceed
the TE-6300P Series Temperature Sensor’s
electrical ratings.
