Installing RP-V on a Damper that Rotates Counter-Clockwise (CCW) to Open

You install the RP-V directly over the VAV damper shaft for damper positioning control and air flow sensing. When you install the RP-V on a damper that rotates counter-clockwise (CCW) to open, use WorkStation or the Commission mobile application to ensure that the configured direction of the actuator rotation matches the damper type.

VAV DAMPER NOT PROPERLY CONTROLLED

Ensure that the VAV controller damper actuator can rotate freely between the fully open and fully closed positions.

Failure to follow these instructions can result in the VAV damper not being properly controlled by the controller.

The RP-V incorporates an integral actuator and the device is designed for over-the-shaft damper installation.

RP-V models with built-in wireless chip must be professionally installed to comply with the following rules and regulations:

  • Part 15 of the Federal Communications Commission (FCC) rules

  • Innovation, Science and Economic Development Canada (ISED) licence-exempt Radio Standards Specifications (RSSs)

  • 2014/53/EU Radio Equipment Directive (RED) of the European Union (EU)

  • S.I. 2017/1206 - Radio Equipment Regulations 2017 of the United Kingdom (UK)

Pour plus d'informations, voir RP-V Regulatory Compliance and Approvals .

The RP-V and its antenna(s) must be installed to provide a separation distance of at least 20 cm (8 in.) from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Information on recommended RF exposure limits can be obtained from Health Canada's website, www.canada.ca/en/health-canada .

The supported installation orientations do not differ between the different RP-V models:

  • RP-V-4A

  • RP-V-5A

  • RP-V-5C-M

The RP-V is typically installed with the air flow sensor barbed fittings pointing down (orientation B in the figure below). The RP-V can also be installed with the barbed fittings pointing left (A), right (C), or up (D).

 
action_zoom_plus_stroke Supported installation orientations
Figure : Supported installation orientations

With a downward extension, the available area around the damper shaft must measure:

  • 160 mm (6 inches) down from the lower edge of the shaft,

  • 120 mm (4.5 inches) to the right,

  • 45 mm (1.75 inches) to the left, and

  • 45 mm (1.75 inches) above the shaft.

Ensure that the location allows enough clearance for servicing.

The RP-V actuator is designed to be installed over a 12.7 mm (0.5 inch) diameter round damper shaft with a minimum of 54 mm (2.125 inches) exposed damper shaft length.

When the damper shaft diameter is less than 12.7 mm (0.5 inch), an adapter is required. An adapter with part number AM-135 can be ordered from Schneider Electric to enable installation on a 9.5 mm (0.375 inches) diameter damper shaft.

Déclaration

The cutout section of the shaft adapter must be positioned such that the damper shaft mounting screws are tightened against the damper shaft and not the adapter cylinder.

When the exposed damper shaft length is less than 54 mm (2.125 inches) but greater than 22.2 mm (0.875 inch), you move the damper shaft mounting screws from the actuator threaded hub to the alternative screw holes on the RP-V actuator.

The RP-V onboard air flow sensor is connected to an air velocity probe in the VAV box using two tubes. A dip in the tubing helps prevent moisture from entering the RP-V and damaging the air flow sensor. The dip should extend below the elevation of the barbed fittings. This applies to all RP-V orientations.

Déclaration

AIR FLOW SENSOR DAMAGE

  • Do not expose the VAV controller's air flow sensor inputs to moisture during installation or operation.

  • Create a tubing dip that extends below the elevation of the barbed fittings to help prevent moisture from entering the VAV controller. This applies to all controller orientations.

Failure to follow these instructions can result in equipment damage.

When operating in an unusually dusty environment, it is recommended to connect an in-line air filter (Schneider Electric part number 01-2100-272 or equivalent filter) on the high side pressure tube from the VAV box. The filter should be positioned close to the VAV box. The low flow of the sensor helps prevent most of the dust migration. The filter adds protection to help prevent dust from entering the velocity measurement tube in a dusty environment.

When the RP-V is powered up for the first time, the RP-V software automatically performs an actuator travel and damper position calibration. The calibration operation drives the damper actuator in the close direction and registers the position when the actuator encounters the stop. The software then drives the actuator in the open direction and registers the position when the stop is encountered. The software uses that information to scale the 0 to 100% span. Mechanical obstructions hindering the damper actuator rotation during the calibration process can adversely affect the calibration results and thus the VAV damper operation. In that case, after removing the mechanical obstruction, you can manually run a recalibration. Pour plus d'informations, voir Configuring a Damper Command .

Déclaration

Initial calibration of actuator travel and damper position is performed automatically when the RP-V is powered up for the first time. If you subsequently press the manual override button, you must recalibrate the RP-V manually. Pour plus d'informations, voir Configuring a Damper Command .

VAV DAMPER NOT PROPERLY CONTROLLED

  • Ensure that the VAV controller is properly installed and secured prior to application of the 24 VAC power.

  • Ensure that the VAV controller damper actuator can rotate freely between the fully open and fully closed positions.

Failure to follow these instructions can result in the VAV damper not being properly controlled by the VAV controller.

The RP-V models have fixed screw terminals.

To install RP-V on a damper that rotates counter-clockwise (CCW) to open

  1. Refer to the dimensional drawing before installing the RP-V.

     
    action_zoom_plus_stroke

  2. Ensure that the damper is of the type that opens by turning the damper shaft counter-clockwise (CCW).

     
    action_zoom_plus_stroke

  3. Determine the damper shaft length (L) and diameter (D).

     
    action_zoom_plus_stroke

  4. When the exposed damper shaft length (L) is less than 54 mm (2.125 inches) but greater than 22.2 mm (0.875 inch), move the two damper shaft mounting screws to the alternative screw holes for shorter damper shaft lengths.

    Pour plus d'informations, voir Moving the Damper Shaft Mounting Screws to the Alternative Positions for Short Shafts Only on RP-V .

  5. When the damper shaft diameter (D) is equal to 9.5 mm (0.375 inch), install an AM-135 shaft adapter on the damper shaft.

    Pour plus d'informations, voir Installing an AM-135 Shaft Adapter on a 9.5 mm (0.375 inch) Diameter Damper Shaft .

  6. Rotate the damper shaft to fully closed (CW) position.

     
    action_zoom_plus_stroke

  7. Press and hold the manual override button and rotate the actuator hub to fully closed (CW) position.

     
    action_zoom_plus_stroke

  8. Release the manual override button. If necessary, rotate the actuator hub slightly to make the button return to the fully extended position.

  9. Loosen the two damper shaft mounting screws using a 1/8-inch hex key and slide the controller over the damper shaft until the anti-rotation clip comes in close contact with the mounting area on the VAV box.

    Déclaration

    When necessary due to mounting area restrictions or obstacles, the anti-rotation clip can be moved from the mounting bracket at the bottom of the controller (factory delivered location) to the mounting bracket on the side of the controller (alternative location).

     
    action_zoom_plus_stroke

  10. To preload the damper for closed position, rotate the controller counter-clockwise (CCW) about three degrees or 10 mm (0.4 inch) off centerline of the damper.

     
    action_zoom_plus_stroke

  11. Tighten the two damper shaft mounting screws to the recommended torque using a torque wrench. For steel damper shafts, 6.8 to 7.9 Nm (60 to 70 lbf.in) is recommended. For aluminum damper shafts, 4.0 to 5.1 Nm (35 to 45 lbf.in) is recommended.

    Déclaration

    When using the alternative positions for shorter damper shaft lengths, tighten the mounting screw that can be accessed, rotate the hub 90 degrees counter-clockwise (CCW) and tighten the other screw, then rotate the hub back 90 degrees clockwise (CW). Recommended screw tightening torque:

    • Steel damper shafts: 6.8 to 7.9 Nm (60 to 70 lbf.in)

    • Aluminum damper shafts: 4.0 to 5.1 Nm (35 to 45 lbf.in)

    Déclaration

    When using an AM-135 shaft adapter, position the cutout section of the adapter cylinder to match the damper shaft mounting screw positions, before you tighten the screws against the damper shaft through the cutout section. Do not tighten the screws against the adapter cylinder.

     
    action_zoom_plus_stroke

  12. Rotate the controller clockwise (CW) back into alignment with the centerline of the damper. The damper should now be tightly closed.

     
    action_zoom_plus_stroke

  13. Using the controller's anti-rotation clip as a template, mark and drill a pilot hole in the VAV box.

  14. Ensure the mounting hole position does not affect the performance of the VAV terminal unit. If the damper movement is affected, install the anti-rotation clip in the mounting bracket on the side of the controller (alternative location).

  15. Secure the anti-rotation clip to the VAV box using a #10 self-tapping sheet metal screw.

     
    action_zoom_plus_stroke

  16. Press and hold the manual override button and rotate the damper counter-clockwise (CCW) to fully open position by rotating the damper shaft.

     
    action_zoom_plus_stroke

  17. Release the manual override button. If necessary, rotate the actuator hub slightly to make the button return to the fully extended position.

  18. Loosen the CCW travel adjustment screw using a 1/4-inch hex key, slide the screw to the damper position indicator, and tighten the screw to 1.4 to 2.0 Nm (12 to 18 lbf.in) using a torque wrench.

    Déclaration

    Loosen the screw only a quarter of a turn.

     
    action_zoom_plus_stroke

  19. Verify that damper can rotate freely between the fully open and fully closed positions. There must be no binding between the actuator and damper, or obstructions hindering the damper operation.

     
    action_zoom_plus_stroke

  20. In WorkStation, ensure that Counterclockwise to open is the chosen direction of the actuator rotation to open the damper.
