M9220-Bxx-3 On/Off Electric Spring Return Actuators Installation Instructions 1

Refer to the QuickLIT Web site for the most up-to-date version of this document.

Applications

The M9220-Bxx-3 On/Off Actuators are direct-mount,

spring return electric actuators that operate on AC 24 V

power at 50/60 Hz, DC 24 V power, AC 120 V power at

60 Hz, or AC 230 V power at 50/60 Hz. These

bidirectional actuators do not require a damper linkage,

and are easily installed on dampers with 1/2 to 3/4 in.

or 12 to 19 mm round shafts, or 3/8 and 1/2 in. or 10,

12, and 14 mm square shafts using the standard shaft

clamp included with the actuator. An optional

M9220-600 Jackshaft Coupler Kit is available for 3/4 to

1-1/16 in. or 19 to 27 mm round shafts, or 5/8 and 3/4

in. or 16, 18, and 19 mm square shafts.

A single M9220-Bxx-3 On/Off Electric Spring Return

Actuator provides a running and spring return torque of

177 lb⋅in (20 N⋅m). Two like models mounted in tandem

using the M9000-158 Tandem Mounting Kit deliver

twice the torque or 354 lb⋅in (40 N⋅m). Integral line

voltage auxiliary switches are available on the BxC

models to indicate end-stop position, or to perform

switching functions within the selected rotation range.

Installation

The M9220-Bxx-3 On/Off Electric Spring Return

Actuators mount directly to the surface in any

convenient orientation using two M3 x 9.5 mm

self-drilling sheet metal screws and the anti-rotation

bracket (parts included with the actuator). No additional

linkages or couplers are required. Electrical

connections are color-coded and identified with

numbers permanently marked on the actuator cable.

A tag on the actuator cable identifies the electrical

connections, and wiring details are also included on the

actuator housing.

Parts Included

• on/off electric spring return actuator with coupler

• anti-rotation bracket

• manual override crank

• two M3 x 9.5 mm self-drilling sheet metal mounting

screws

• two No. 10-32 x 9/16 in. thread-forming conduit

screws

Special Tools Needed

• torque wrench with 3/8 in. (10 mm) socket

• digital voltmeter or M9000-200 Commissioning

Tool

IMPORTANT: Use this M9220-Bxx-3 On/Off

Electric Spring Return Actuator only to control

equipment under normal operating conditions.

Where failure or malfunction of the electric actuator

could lead to personal injury or property damage to

the controlled equipment or other property,

additional precautions must be designed into the

control system. Incorporate and maintain other

devices, such as supervisory or alarm systems or

safety or limit controls, intended to warn of or protect

against failure or malfunction of the electric actuator.

IMPORTANT: Do not install or use this

M9220-Bxx-3 On/Off Electric Spring Return Actuator

in or near environments where corrosive substances

or vapors could be present. Exposure of the electric

actuator to corrosive environments may damage the

internal components of the device, and will void the

warranty.

Counterclockwise (CCW) Spring Return Direction – Clockwise (CW) Powered Operation For CCW spring return direction, mount the actuator to the damper shaft so that the Side A of the actuator is away from the damper as illustrated in Figure 2. With power applied, the actuator drives CW from the 0° position, and spring returns CCW. Removable Coupler The coupler may be installed on either side of the output hub. If the damper shaft is less than 3-19/32 in.

Note: The actuator requires 27 rotations of the manual override crank from the fully spring return position to fully reposition the actuator hub. At the end of travel, the rotational resistance increases; do not force the actuator hub past this point. 2. Bend or cut the anti-rotation bracket to fit the damper frame or duct as illustrated in Figure 6. Note: The anti-rotation bracket can be bent to fit a round damper. Anti-rotation Bracket 4.

7. Evenly hand tighten each clamp nut onto the U-bolt, keeping the actuator flat. Secure the U-bolt to the damper shaft and tighten to a torque of 100 to 125 lb⋅in (11 to 14 N⋅m). 8. To release the spring, turn the manual override crank in the direction indicated on the label; the actuator spring returns to its starting position. If this step is omitted, the spring releases automatically when power is applied to the actuator.

The tandem configuration provides twice the running and spring return torque of a single actuator, or 354 lb⋅in (40 N⋅m). The two actuators mounted in tandem using the M9000-158 Tandem Mounting Kit operate in exact synchronization, causing the load to be split evenly between each actuator. Use two actuators from the same model type for tandem operation. BGx models used in the tandem configuration are wired in parallel.
