MSXX04 & MSXX09 Series Actuators

INSTALLATION INSTRUCTIONS

These instructions apply to the external field installation of the Honeywell actuators on Greenheck models VCD Control Dampers when they are duct mounted or sleeved.

These models are direct drive actuators that rotate to their energized position when power is applied, and spring return to their fail position when power is disconnected.

Tools Required:

Wrenches: (1) 7⁄16 in., (1) 3⁄8 in.

(1) Ratchet with 3⁄8 in. deepwell socket

⁄8 in. Allen wrench

(1)

Part No. Quantitiy Description

1 1 External Mounting Bracket

2 1 #10-24 x .375 Shoulder Bolt

3 1 #10-24 Nut

4 8 1/4 - 20 x 1/2 Spinlock Bolt

5 8 1/4-20 Spinlock Nut

6 1 Actuator

7 1 Standoff Bracket

8 1 Extension Pin - 5 3/4 in. long

9 1 Retaining Clip - 1/2 in. dia.

Figure 1: Honeywell MSXX04 & MSXX09 Series external mount (exploded view).

Actuator can be ﬂipped aroung to reverse rotation.

Note: Bracket (7) is not used when damper model is VCDR or VCDRM series. On VCDR and VCDRM models, the bracket (1) is bolted directly to the damper shaft upport bracket.

With Jackshaft

Without Jackshaft

Note: Actuator shaft collar accepts 1/2 in. (13mm) diameter shaft.

WARNING

Equipment Damage or Electrical Power Hazard. Line voltage can cause death or serious injury and short equipment circuitry. Disconnect power supply before installation.

CAUTION

Device Malfunction Hazard. Improper set screw tightening causes device malfunction. Tighten set screws with proper torque to prevent damper shaft slippage.

FATPA DIRECT DRIVE SERIESINSTRUCTIONS

These installation instructions assume the damper is already mounted in a duct or sleeve with the damper shaft extending beyond the duct or sleeve 6 inches (152mm).

1. Install the stand-off bracket

Dampers with a jackshaft

1a. Remove the 1/2 in. (13mm) ball bearing from the

standoff bracket. Mount the stand-off bracket (item #7) with [4] ¼-20 x ½ in. (M6 x 12mm) spinlock bolts and nuts (item #4 and 5). Orient the stand-off bracket (item #7) so the hole is centered on the jackshaft (see Figure 1, With Jackshaft).

Dampers without a jackshaft (Shaft Extension) 1b. Mount the stand-off bracket (item #7) spanning

across the damper frame flanges. Fasten to the damper frame with [4] ¼-20 x ½ in. (M6 x 12mm) spinlock bolts and nuts (item #4 and 5). Be sure not to run the screws into the damper linkage, which is between the flanges.

2. Mount actuator bracket Fasten the actuator bracket (item #1) (See Figure

1) to the standoff bracket (item #7) using [4] ¼-20 x

½ in. (M6 X 20mm) spinlock bolts and nuts (item #4 and 5). Use outer four holes of the actuator bracket (item #2).

3. Fail Position If fail position is closed, make sure damper

blades are fully close and ensure blade seals are compressed prior to tightening the actuator clamp to the damper extension pin or jackshaft.

4. Install the actuator

Install the actuator (item #6) over the damper drive

shaft and tight against the actuator bracket (item #1). Install [1] #10-24 x .375 shoulder bolts (item #2) through lugs on actuator and through the holes in back of the actuator bracket (item #1). Secure with [2] #10-24 nuts (Item #5) (See Figure 1).

5. Secure actuator (Item #6) to drive shaft by tightening the set screws on actuator collar.

6. The wiring illustration identifies actuator electrical requirements and connections (See Figure 2). Wiring must comply with all applicable electrical codes.

7. Apply power to the actuator. The damper blades should fully open or close and return to the fail position when power is disconnected.
