The control damper mechanism on the VAV terminal unit is maintenance-free. To ensure perfect functioning of the entire system, function tests should be carried out as part of the regular system maintenance. The following criteria should be used: 1. Does the room temperature controller function? 2. Does the volume flow controller function? 3. Does the actuator turn in both directions? 4. Does the transducer output signal vary according to the actuator movements? 5. Do the override controls such as shut off function? 6. Are the tubing connections airtight? Further details on fault diagnosis are given in the information on each controller type. Replacement of Control Components If faulty control components have to be replaced, the following principles must be observed: • Spare parts must comply with the technical requirements of the manufacturer. Only use original spare parts. • Disconnect supply voltage 24 volts or operating pressure. • Mark wiring/tubing connections before releasing. • Carefully remove pneumatic tubing without pulling. • Replace component and all connections. When replacing controllers and transducers, they must be adjusted to suit the unit size. Therefore electronic and pneumatic components are preset in the Trox works. Digital controllers can be set up by the customer. When changing actuators, note the following: • Mechanical rotation angle limiters on the new actuator should be set as the existing unit. A slot in the control damper shaft shows the position of the blade. • Direction of rotation should be set as before (switch or plug setting).
