Wiring
Caution:
•
Do not use unshielded sensor cable in the same conduit with 120/240 Vac power
wiring, or in areas with high RFI/EMI generating devices.
•
Shielded cable must be used when it is necessary to install the sensor leads in the same
conduit with power wiring, or when it is known that devices generating high RFI/EMI are
near. Ground the shield according to the controller or controlled device manufacturer's
specification.
•
For TAC NETWORK 8000 applications, follow the recommended shielding and wiring
practices in the
TAC NETWORK 8000 Hardware Installation Practices Manual, F-
23061
.
•
Do not use the inside of the sensor cover or electrical box as a termination location for
other control circuits.
Wiring connections to the temperature sensor are made during the mounting process. Be
sure to observe the following wiring guidelines:
•
Two-conductor twisted pair wires (six turns per foot), Class II, low voltage, are suitable
for the sensor leads.
Use copper conductors only.
•
Restrict wiring leads to the shortest practical length. For recommended wiring lengths,
refer to Table-3, below.
Table-3 Typical Sensor Wiring Lengths.
CHECKOUT
Use a Digital Volt-ohm Meter (DVM) to measure the resistance between the two field
connection terminals on the temperature sensor (see Figure-1 for terminal identification).
MAINTENANCE
The temperature sensor requires no maintenance. However, the sensor should be
periodically inspected for dirt and for any blockage of the airflow over the elements.
Regular maintenance of the total system is recommended to assure sustained, optimum
performance.
FIELD REPAIR
None.
