Operation MS41-6153 Series Apply a 0 to 10 Vdc control signal between wire 8 (Y) and wire 2 (G0) to operate the damper actuator. The angle of rotation is proportional to the control signal. A 0 to 10 Vdc position feedback output signal is available between wire 9 (U) and wire 2 (G0) 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 "0" position.

Mounting and Installation Manual Override • 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 3/4-inches (20mm). The shaft length determines whether the shaft adapter will be mounted on the front or back of the actuator. • See Specifications for minimum and maximum damper shaft dimensions.

3. Return the actuator gear train to the "0" position using the steps that follow for the clockwise or counterclockwise damper shaft rotation. Mechanical Range Adjustment, Continued Clockwise to open: a. Insert the shaft adapter to the right as close as possible to the raised stop. See Figure 4. b. Hold down the PUSH button and rotate the shaft adapter to the left until it stops. See Figure 5. c. Release the PUSH button. d.

All wiring must conform to NEC and local codes and regulations. Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers. Wiring The maximum rating for a Class 2 step-down transformer is 100 VA. Determine the supply transformer rating by summing the VA ratings of all actuators and all other components used. It is recommended that one transformer power no more than 10 actuators (or 80% of its VA).

Start-Up/ Commissioning 1. Check Operation: Non-spring Return Modulating Control (0 to 10 Vdc) 24 Vac 2. 3. a. Connect wires 1 (red) and 2 (black) to the 24 Vac power supply. b. Set the Digital Multimeter (DMM) dial to Vdc for the actuator input signal. c. Connect wires 2 (black) and 8 (gray) to a Digital Multimeter (DMM). d. Apply a full-scale input signal (10 Vdc) to wire 8 (gray). e. Allow the actuator shaft coupling to rotate from 0 to 90°. f. Stop the signal to wire 8 (gray).

Start-Up/ Commissioning, Continued 5. Check Operation: a. Apply a control signal (24 Vac) to wires 1 (red) and 6 (violet). Non-spring Return Three-position 24 Vac b. Allow the actuator shaft coupling to rotate from 0 to 90°. c. Stop applying a control signal to wires 1 (red) and 6 (violet). d. Apply a control signal (24 Vac) to wires 1 (red) and 7 (orange). e. Allow the actuator shaft coupling to rotate from 90° to 0°. Service WARNING: Do not open the actuator.
