W7751H3007 VAV ACTUATORS

HONEYWELL EXCEL 5000 OPEN SYSTEM

BEFORE INSTALLATION

The W7751H Smart VAV Actuator consists of a factorycombined variable air volume (VAV) box controller and a direct-coupled damper actuator with de-clutch mechanism. The actuator/controller assembly is field-mounted to the VAV box damper shaft similar to the mounting of a standard actuator, and the controller wiring is terminated to the screw terminals accessible inside the detachable wiring box. See Fig. 2.

The W7751H's built-in actuator with de-clutch mechanism allows the installer to manually open or close its built-in VAV box damper without power or software tool.

The W7751H contains a Free Topology Transceiver (FTT) LonMark® compliant controller containing a Microbridge flowthrough pressure sensor and communicates via the 78 kbaud L

ONWORKS

The W7751H actuator mounts directly onto the VAV box damper shaft and has up to 6 Nm torque, 95 degree stroke, and 110 sec. timing at 50 Hz and 90 sec at 60 Hz.

If desired, the SSW2 Auxiliary Switch Kit (see "SSW2 Auxiliary Switch Kit for N05xx, N10xx Non-Spring Return Direct-Coupled Damper Actuators – Installation Instructions", Product Literature No.: MU1B-0284GE51) can be attached to the W7751H. See also section "Optional Accessories" on page 9.

Mount the W7751H on the damper shaft and allow clearance for wiring, servicing, and module removal. Avoid mounting the W7751H in areas where acid fumes or other corrosive vapors can attack the actuator's metal parts, or in areas where escaping gas or other explosive vapors are present. See Fig. 23 for mounting dimensions.

The W7751H is field-mounted to the VAV box damper shaft. The W7751H actuator opens or closes a damper by driving the damper shaft in either the counterclockwise (CCW) or clockwise (CW) direction. If the W7751H is to be mounted directly onto a damper shaft, use the mounting bracket and screw included in the delivery.

The wiring of the W7751H controller is terminated to a screw terminal block accessible inside the detachable wiring box. See section "Wiring".

The W7751H actuator is shipped in the fully counterclockwise (CCW) position (95 degrees). Mount the W7751H so that the actuator is parallel with the VAV box damper housing.

CAUTION

Equipment damage hazard. Mounting actuator unevenly with damper housing can damage actuator.

Mount the actuator flush with the damper housing or add a spacer between the anti-rotation bracket and the VAV damper box housing (see Fig. 6).

Before mounting the W7751H onto the VAV box damper shaft, do the following:

1. Ensure that the diameter of the damper shaft is within the allowed limits (round: 8…16 mm, square: 6…13 mm).

EN1B-0279GE51 R0707B

Page 3

2. Ensure that the damper shaft has a length of at least 40 mm.

3. Determine the direction (CW or CCW) in which the damper shaft rotates to open the damper (see Fig. 7).

4. Determine the angle of the damper opening (can be adjusted in increments of 5.5°).

Fig. 7. Determining direction of rotation

The W7751H actuator is shipped in the fully counterclockwise (CCW) position (95 degrees). The installation procedure varies depending on the damper direction.

NOTE: Be aware that, until the W7751H is powered and the

damper is driven open, starting the fan system with all the VAV box dampers closed can cause duct over-pressurization and damage.

If Damper Rotates CW to Open

If the damper rotates clockwise (CW) to open, mount the W7751H as follows:

1. Manually open the damper.

2. Push down the declutch button of the W7751H, and while

holding it down, manually rotate its shaft adapter fully to the clockwise position.

3. Mount the W7751H to the VAV damper box and shaft.

4. Set the mechanical end limits of the W7751H (see Fig. 8).

When the W7751H closes, the damper will thus rotate CCW until the mechanical end limits are reached.

If Damper Rotates CCW to Open

If the damper rotates counterclockwise (CCW) to open, mount the W7751H as follows:

1. Manually open the damper.

2. Push the declutch button of the W7751H, and while

holding it down, manually rotate its shaft adapter fully to the counterclockwise position.

3. Mount the W7751H to the VAV damper box and shaft.

4. Set the mechanical end limits of the W7751H (see Fig. 8).

When the W7751H closes, the damper will thus rotate CW until the mechanical end limits are reached.

EXCEL 10 W7751H SMART VAV ACTUATOR

Fig. 8. Setting the mechanical end limits

Reconfiguring to Match Rotation Direction

Using the LNS plug-in, the W7751H can be reconfigured to match the direction the damper shaft rotates to open the damper. Reconfigure the damper's direction of rotation to "open" or "closed," according to your needs.

To change the damper direction from CW to CCW using the LNS plug-in, proceed as follows.

1. Open the configuration part of the plug-in and select the "Wiring" tab (see Fig. 9).

Fig. 9. Wiring tab (default configuration)

2. Then deselect the output configuration (see Fig. 10).

fan startup. Use the de-clutch button to open the W7751H's box damper only after the W7751H has been powered down (this is to prevent overpressurization in the ductwork on fan startup). To use the de-clutch button, press and hold down the button (this disengages the motor). Turn the damper shaft until the damper is open and then release the button. When power is restored to the W7751H, it synchronizes the damper actuator so that the damper is in the correct position on startup.

Air Flow Pick-up

Connect the air flow pick-up to the two connectors on the W7751H. See Fig. 12.

NOTES:

• Use 6-mm outside diameter with 1-mm wall thickness plenum-rated 1219 FR (94V-2) pneumatic tubing.

• Always use a fresh cut on the end of the tubing that connects to the air flow pick-ups and the connectors on the W7751H.

Connect the high pressure or upstream tube to the plastic restrictor labeled (+ HI) or P1 and the low-pressure or downstream tube to the restrictor labeled (- LO) or P2. See labeling in Fig. 12.

NOTE: If controllers are mounted in unusually dusty or dirty

environments, a 5-micron disposable air filter is recommended for the high-pressure line (marked as +) connected to the air flow pick-up.

When twin tubing is used from the pick-up, split the pick-up tubing a short length to accommodate the connections.

NOTES:

• The tubing from the air flow pick-up to the W7751H should not exceed 0.914 m in length. Lengths much longer than this can degrade the flow sensing accuracy.

EN1B-0279GE51 R0707B

Page 5

• To avoid damaging the air flow connectors, use caution when removing tubing from them. Always pull straight away from the connector; never remove by pulling at an angle.

Wiring

All wiring must comply with applicable electrical codes and ordinances, or as specified on installation wiring diagrams.

NOTES:

• 24 Vac power connections. Verify that multiple controllers powered by the same transformer are wired with the transformer secondary connected to the same input terminal numbers on each W7751. See Fig. 13. Controller configurations are not necessarily limited to three devices, but the total power draw including accessories cannot exceed 100 VA when powered by the same transformer. For power wiring recommendations, refer to Excel 10 W7751B,D,F,H,J Variable Air Volume Controller – Application Guide (Product Literature No.: 74-2949).

• In the case of multiple W7751H units operating from a single transformer, the same side of the transformer secondary must be connected to the same input terminal in each W7751H and the ground terminals (terminal 3 of the W7751H) must be connected to a verified earth ground for each controller in the group. See Fig. 14. Controller configurations are not necessarily limited to three devices, but the total power draw including accessories cannot exceed 100 VA when powered by the same transformer. For power wiring recommendations, refer to Excel 10 W7751B,D,F,H,J Variable Air Volume Controller – Application Guide (Product Literature No.: 74-

2949).

• All loads on a W7751H must be powered by the same transformer that powers the W7751H.

• Keep the earth ground connection (terminal 3) wire run as short as possible. See Fig. 14.

• Do not connect the analog ground (terminal 5) to the earth ground. See Fig. 15.

Wiring Details

Wire to the terminal blocks as follows:

1. Strip 5 mm insulation from the conductor

2. Insert the wire into the required terminal location and

tighten the screw to complete the termination.

NOTE: Earth ground wire length should be held to a

minimum. Use the heaviest gauge wire available, up to 14 AWG (2.0 mm2), with a minimum of 18 AWG (1.0 mm

NOTE: With the exception of 2.0 mm2, if inserting two or

more wires into one terminal location, use end sleeves. Deviation from this rule can result in improper electrical connection.

Fig. 16 through Fig. 21 provide detailed wiring diagrams for the W7751H. See the installation diagrams for specific wiring.

NOTE: Ensure that the wall module's Configuration DIP

Switch is set as shown in Fig. 19. Switches 1 through 3 set the timing of the valve actuator to match the W7751H outputs (minimum of 0.1 s, with a max. time of 25.6 s). Switch 4 determines the action of the actuator (OFF = Direct Acting, ON = Reverse Acting).

CHECKOUT

Step 1. Wiring Connections

Inspect all wiring connections at the W7751H and the T7460 terminals, and verify compliance with installation diagrams. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to:

• Controller wiring: Be sure that each W7751H is wired (terminal 3 on the W7751H) to a verified earth ground using a wire run as short as possible with the heaviest

gauge wire available, up to 2.0 mm

1.0 mm2 for each controller in the group. See Fig. 15.

• Verify that triac wiring to external devices uses the proper load power/24 Vac Hot terminal (terminal 1 on the W7751H).

NOTE: All wiring must comply with applicable electrical

codes and ordinances. See the installation diagrams for specific wiring.

Step 2. Startup

Broadcasting the Service Message

The Service Message allows a device on the LONW network to be positively identified. The Service Message contains the device's ID number and, therefore, can be used to confirm the physical location of a particular W7751H in a building. There are two methods for broadcasting the Service Message from the W7751H:

1. Operating the service pin on the W7751H: Insert a thin rod (e.g. paper clip) into the service pin hole (see Fig. 2) and push briefly; the Service Message will then be broadcast on the network.

with a minimum of

ORKS

2. Using the wall module bypass button: By pressing the wall module's bypass/override button for more than four seconds, the W7751H will send the Service Message (this functionality is supported in firmware version 1.2.15 and higher). When employing this method, the occupancy override state of the W7751H changes depending upon how long the bypass/override button is pressed. For example, if the button is pressed for six seconds, the W7751H will send the Service Message and also enter into the "continuous unoccupied" mode. To clear the "continuous unoccupied" mode, the button must be pressed briefly.

Service LED on the front of the W7751H (see Fig. 2) provides a visual indication of the status of the device. When the W7751H receives power, the LED appears in one of the following allowable states:

1. OFF = no power to the processor.

2. Continuous ON = processor is in initialized state.

3. Slow blink = controlling, normal state.

4. Fast blink = the W7751H has an alarm condition.

When the W7751H has an alarm condition, it reports it to the central node on the L

T7460 Wall Module Override LED

The remote override LED, located on either the T7460 Wall Module, will display the "manual override" mode of the W7751H. Possible modes are:

1. LED = OFF. No override active.

2. LED = Continuously ON. Bypass mode (timed occupied

override).

3. LED = One flash per second. Continuous unoccupied override.

4. LED = Two flashes per second. Remote only, continuous occupied override.

Step 3. I/O Tests

The W7751H controller must be configured using the LNS plug-in. Once this is done, the W7751H can be commanded to the "manual" mode, and each output and input can be exercised/viewed to verify proper wiring connections and equipment operation.

W7751H Actuator Checkout

To check out the W7751H actuator, determine the direction the damper shaft moves to open the damper (CW or CCW). See Fig. 7.

Connect the W7751H with the laptop PC. To do this, the W7751H must be wired, powered, and connected to the portable PC via the LonTalk adapter. The LonTalk® Adapter connects to the W7751H either directly via the L network or via the T7460-LONJACK (accessory available with the T7460 and T7560 Wall Modules). Using the L

ONWORKS

EN1B-0279GE51 R0707B

Page 9

EXCEL 10 W7751H SMART VAV ACTUATOR

tool, you should then drive the W7751H actuator fully open and then closed. Observe the actuator's operation; if the damper is closed, it should begin to open. If the damper is open, it should begin to close.

If no movement is observed, check to see if 24 Vac is present at the W7751H. With proper wiring, with 24 Vac present, and with proper commands from the LNS plug-in, the actuator should operate properly.

Step 4. Verify Sequences of Operation

For the detailed descriptions of the sequences of operation, see Excel 10 W7751B,D,F,H,J Variable Air Volume Controller – Application Guide (Product Literature No.: 74-2949).
