  • Page 4: Features

    FEATURES The TC5-ITA is an electronic device used for air inlet control in livestock buildings. In combination with an environment controller, the TC5-ITA coordinates the movement of the air inlets with the operation of the fans using the real-time clock. Additional units can be connected to the TC5-ITA for an independent control of additional air inlets.

  • Page 7: Installation Procedure

    Integrating an air inlet control system into your ventilation system requires the following equipment: • A Comlink-2 communication module added to your controller • A TC5-ITA controller for each air inlet panel (up to 100 in all) • An alarm system (optional) • A DC power supply (optional) •...

  • Page 9 AND EQUIPMENT DAMAGE. TEMPERATURE PROBES: If your TC5-ITA unit is supplied with a temperature probe, connect it to the PROBE terminal and set internal switch #5 to ON. Note that the TC5-ITA can run without a temperature sensor; in this case, the ROOM TEMPERATURE menu will not be a available.

  • Page 10: Identification Numbers & End Of Line Jumpers

    JUMPERS The TC5-ITA network operates on two communication lines. One line links the TC5-ITA units together to the main controller and the other line links temperature controllers to a computer (this second line is optional). Two jumpers on the Comlink-2 card are used to identify the end of line for each communication line.

    (see illustration beside). For com- munication, always use a 1 twisted pair shielded cable. The maximum length of the cable is 3000m and the recom- mended wire diameter is 1.0 mm. Use a lightning protection module when running the cable between buildings. TC5-ITA rev.02...

  • Page 13: Identifying Primary And Slave Units

    Identifying Primary and Slave Units If your installation requires more than one TC5-ITA unit for independent control of different air inlets, one of the TC5-ITA will be configured as the primary unit and the others will be configured as slaves. Up to 99 slave units can be connected in this way.

    SET POINT Inlet & Tunnel Modes: When the last reference point is reached, the TC5-ITA can either open the air inlet according to a user-defined value (internal switch #12 to OFF), or it can fully open the air inlet up until the inlet reaches its limit switch (internal switch #12 to ON).

  • Page 18: Calibration

    TC5-ITA Calibration The TC5-ITA adjusts the opening of air inlets according to the ventilation stages provided by the environment controller. The calibration allows TC5-ITA units to detect how many On/Off and variable stages the environ- ment controller uses. When the calibration is launched on the PRIMARY TC5-ITA unit, the envi- ronment controller enters in test mode and starts simulating the room tem- perature.
  • Page 19 TC5-ITA unit to start the calibration. 3. Once the calibration is launched, press and hold the right-arrow key for 2 seconds on all TC5-ITA slave units within the next 30 sec- onds. 4. After 30 seconds, the environment controller enters in test mode and starts simulating the room temperature.

    Use the adjustment buttons to set the hours to the desired value. Identification Number This function displays the identification number of the TC5-ITA along with its primary/slave status. The identification number is set using jumpers on the COMLINK-2 communication card (see INSTALLATION PROCEDURE chapter).

  • Page 21: Total Opening Time

    • Proceed in similar fashion to set the total opening time on all TC5-ITA units. Opening Display The user must assign an inlet position to each ventilation stage. This posi- tion can either be specified as a moving time of the actuator or as a per- centage of the total run time.

  • Page 22: Programming Inlet Openings

    • Enter the total opening time of the inlet of each TC5-ITA unit. PROGRAMMING INLET OPENINGS: • Select "PROGRAMMING" using the function selection buttons (note that this menu is not available during the calibration) The opening time or the inlet position (in %) associated with step 0 is displayed.

  • Page 23: Remaining Run Time / Opening Menu

    The letters "STOP" are dis- played if the inlet is not moving. If the inlet opening is displayed as a percentage, the REMAINING RUN TIME / OPENING menu shows the current opening (in %) of the air inlet. TC5-ITA rev.02...
