ACI TS-3200-DD-xx-AA Series Installation and Operation Instructions
Please Read Instruction Carefully Before Installation!
Applications
There are a number of applications in which the TS-3200-DD-xx-AA Series may be used to monitor and control the building temperature. A few of the most common applications are listed below:
- Monitoring Outside Air Temperature
- Monitoring Cold Storage Facilities Air Temperature
- Monitoring Temperature in Applications where Wash downs may occur
Operating Specifications
The TS-3200-DD-xx-AA Series outdoor mounted temperature sensors have an output signal of 3K Ohms at 77°F (25°C) or 10K Ohms (Type II) at 77°F (25°C). The outdoor mounted temperature sensors have an overall accuracy of ± 0.36°F (0.2°C) for the regular sensor or ± 0.18°F (0.1°C) for the HI sensor over the range of 32 to 158°F (0 to 70°C). The outdoor mounted temperature sensors shall have two 22 AWG colored etched Teflon lead wires. The TS-3200-DD-xx-AA Series outdoor mounted temperature sensors can be used in environments where the operating temperature is between -40 to 302°F (-40 to 150°C).
All TS-3200-DD-xx-AA Series outdoor mounted temperature sensors are both non-polarity and non-position sensitive.
| Part Number | Sensor Type | Wire Colors |
|---|---|---|
| TS-3200-DD-03-AA | 3K Ohms | Blue / Blue |
| TS-3200-DD-10-AA | 10K Ohms | Yellow / Yellow |
| TS-3200-DD-10-AA-HI | 10K Ohms - HI | Orange / Orange |
Installation
The TS-3200-DD-xx-AA Series outdoor mounted temperature sensors are provided in a weatherproof enclosure. Be sure to mount the sensor so that the unit is under an Eave, Shield, or in an area that is out of elements or direct sunlight (example: North Side of a Building), with the sensor probe pointing downward (See Figure #1).
Installation (Continued)
- Attach the mounting lugs to the back of the Bell box, or mount the Bell box onto a threaded conduit connector.
- Position the outdoor mounted temperature sensor where it is to be mounted and mark the (2) mounting holes in the mounting lugs. Use two #8 self-tapping Sheet Metal or TEK screws to mount the sensor.
- Now install a watertight fitting or conduit connectors.
- Install the cable from the Building Automation System into the outdoor temperature sensor. ACI recommends the use of a multi-conductor shielded cable for all sensor installations. The foil shield should be connected to Ground at the Building Automation System (DDC Controller).
- Next connect the sensor wires to the cable from the Building Automation System using the supplied wire nuts.
- Now place secure the cover and rubber gasket onto the Bell box using the two screws provided with the cover.
- Now verify that you are getting a temperature reading on your Building Automation System.
Troubleshooting
Sensor reads 0 ohms or very low
Sensor or wires are shorted together
Sensor reads infinity or very high
Sensor or wires are cut or open
Erratic readings
Bad wire connections - Condensation or Moisture problem
Inaccurate Sensor
If you suspect that the sensor is not reading within the specified tolerance, disconnect the sensor wires from the Building Management System (DDC Controller) and attach a NIST traceable ohmmeter across the two wires. Compare the reading to the table listed below. If you feel that the sensor is different from the table below please contact ACI for further assistance.
WEEE Directive
At the end of their useful life the packaging and product should be disposed of via a suitable recycle centre. Do not dispose of with household waste. Do not burn.
