Operation DCM4- and DCM4--Z pply a to Vdc control signal between wire 8 (Y) and wire (G) to operate the damper actuator. The angle of rotation is proportional to the control signal. to Vdc position feedback output signal is available between wire 9 (U) and wire (G) to monitor the position of the damper motor. In the event of a power failure, the actuator holds its position. In the event that only the control signal is lost, the actuator returns to the "" position. DC4--T, DC4--T floating control signal controls the damper actuator. The actuator s angle of rotation is proportional to the length of time the signal is applied. 4 Vac control signal to wire 6 (Y) causes the actuator coupling to rotate clockwise. 4 Vac control signal to wire 7 (Y) causes the actuator coupling to rotate counterclockwise. To reverse the direction of rotation, wires 6 (Y) and 7 (Y) can be interchanged. With no control voltage, the damper actuator holds its position. Overload Protection In the event of a blockage in the damper, the actuator is overload protected over the full rangeto prevent damage to the actuator. PGE

4 Damper Mounting and Installation Place the actuator on the damper shaft so that the front of the actuator is accessible. (The label and the manual override button are on the front side.) The minimum damper drive shaft is /4-inches (mm). The shaft length determines whether the shaft adapter will be mounted on the front or back of the actuator. Refer to Specifications for minimum and maximum damper shaft dimensions. Set auxiliary switches, DIP switches, and Offset/Span as required by your application. (See following sections for details.) The position indicator can be mounted to show either the clockwise or counterclockwise to scale. mounting bracket is included with the actuator. The shaft adapter and mounting parts are shipped in a separate container with the actuator. The actuator is shipped from the factory with a 5 pre-load to ensure tight damper close off. Detailed mounting instructions are included with each actuator. Manual Override To move the damper blades and lock the position with no power present:. Hold down the PUSH button.. Make adjustments to the damper position.. Release the PUSH button. Once power is restored, the actuator returns to automated control. L > in. 77mm PUSH L < -/8 in. 6mm PUSH Mechanical Range djustment The angular rotation is adjustable between and at 5-degree intervals. The range of shaft movement is limited by mounting the shaft adapter:. Loosen the shaft adapter from the damper shaft and remove the actuator from the damper shaft.. Remove the clip and shaft adapter from the actuator Figure. Figure. Figure 4. Figure 5.. Return the actuator gear train to the position using the steps that follow for the clockwise or counterclock wise damper shaft rotation. Clockwise to open: a. Insert the shaft adapter to the right as close as possible to the raised stop. See Figure. b. Hold down the PUSH button and rotate the shaft adapter to the left until it stops. See Figure 4. c. Release the PUSH button. d. If the shaft adapter is not resting against the left raised stop, remove the adapter and insert it against the left stop. e. Place the position indicator to the position on the outside scale. See Figure 5. Counterclockwise to open: a. Insert the shaft adapter to the left as close as possible to the raised stop. b. Hold down the PUSH button and rotate the shaft adapter to the right until it stops. c. Release the PUSH button. d. If the shaft adapter is not resting against the right raised stop, remove the adapter and insert it against the right stop. e. Place the position indicator to on the inside scale. 4. Determine the angle of rotation for the damper blade shaft. Subtract that amount from. 5. Remove the shaft adapter and insert it with the position indicator pointing to the mark on the scale calculated in the previous step. See Figure ttach the clip. 7. Rotate the damper blade shaft to its position. 8. Return the actuator to the damper shaft and tighten the shaft adapter to the damper shaft. PGE 4

Use earth ground isolating step-down Class transformers. Do not use autotransformers. The maximum rating for a Class step-down transformer is V. Determine the supply transformer rating by summing the V ratings of all actuators and all other components used. It is recommended that one transformer power no more than actuators (or 8% of its V).
