INTRODUCTION

The high accuracy single point ying lead temperature transmitter utilizes a precision

sensor that is encapsulated in a 50 mm (2”) long x 6 mm (0.236”) diameter OD, 304

series stainless steel probe and is provided with 3.05 m (10’) of plenum rated FT-6 cable.

All probes provide excellent heat transfer, fast response and resistance to moisture

penetration. A compact Polycarbonate enclosure with a hinged and gasketed cover is

provided for ease of installation.

BEFORE INSTALLATION

Readtheseinstructionscarefullybeforeinstallingandcommissioningthetemperature

sensor. Failure to follow these instructions may result in product damage. Do not use

in an explosive or hazardous environment, with combustible or ammable gases, as

a safety or emergency stop device or in any other application where failure of the

product could result in personal injury. Do not exceed the device ratings.

MOUNTING

The ying lead transmitter can be used in several dierent types of applications where single point temperature monitoring is required.

Listed below are some typical applications

The ying lead sensor can be installed directly into any air duct. Select a suitable installation area in the middle of the duct. To achieve the best reading, do

not place in an area where air stratication may be present. Avoid areas where the sensor is exposed to vibrations or rapid temperature changes.

Once a suitable spot is selected, drill a 3/8”hole in the top of the duct and slide the probe through, mount

a length of exible duct hanger from top to bottom of the duct. Mount the probe to the duct hanger

using a tube clamp or wire tie. See Figure 1.

The ying lead could also be used to measure pipe temperature. Select a suitable spot along the pipe,

remove a small section of insulation if present and set aside. It is recommended that thermal compound

be used to improve heat transfer. Spread a liberal amount on the pipe. Lay probe in thermal compound

and secure sensor to pipe using a worm gear clamp (not included).

For added protection it is recommended to wrap the probe cable around the pipe 1 to 2 times. Re-install

insulation if present, allowing sensor cable to protrude. See Figure 2.

The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the latch on the right

side of the enclosure, at the same time pulling on the cover, as shown in Figure 3.

A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure. Screw the EMT connector

or cable gland connector in until tight. See Figure 4. It is recommended that weatherproof conduit or

cable gland ttings be used. The F style enclosure includes a 1/2" NPT to M16 thread adapter and cable

gland tting.

Make wiring connections as per the “Wiring”illustrations on Page 2.

Swing door closed until securely latched. For added security, 2 screws are provided that may be installed

in the integrated screw tabs. See Figure 5.

WIRING

• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent equipment damage.

• Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply

inductive loads such as motors. Make all connections in accordance with national and local codes.

• The temperature transmitter comes with the temperature sensor pre-wired to the transmitter board. If removal is required for installation

then it may be re-wired as shown in Figure 6.

• Pull at least six inches of control wire into the enclosure, then complete the wiring connection according to the wire diagram for the

applicable power supply and output signal type as shown in Figure 7.

• Connect the DC positive or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply Common is connected

to the COM terminal. The device is reverse voltage protected and will not operate if connected backwards. It has a half-wave power supply

so the supply Common is the same as the signal Common. See Figure 7.

• The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper connection before applying

power as shown in Figure 7.

• Once all connections are made and checked, power can be applied.
