Applications

The M9208-GGx-x Series Proportional Electric Spring

Return Actuators are direct-mount actuators that

operate on AC/DC 24 V power. These bidirectional

actuators do not require a damper linkage, and are

easily installed on round shafts from

5/16 to 5/8 in. (8 to 16 mm) or square shafts from

1/4 to 1/2 in. (6 to 12 mm) using the standard shaft

clamp included with the actuator. An optional

M9208-600 Large Coupler Kit is available for round

shafts from 1/2 to 3/4 in. (12 to 19 mm) or square

shafts from 3/8to9/16in.(10to14mm).

A single M9208-GGx-x Series Proportional Electric

Spring Return Actuator provides 70 lb·in. (8 N·m)

running and spring return torque. Integral line voltage

auxiliary switches, available only on the M9208-xxC-3

models, indicate end-stop position, or perform

switching functions within the selected rotation range.

M9208-GGA-2 actuators include plenum-rated cables

and are specially configured for installation in spaces

used for environmental air-handling purposes other

than ducts and plenums as specified in National Fire

Protection Association (NFPA) 70: National Electrical

Code section 300.22(C), Other Space Used for

Environmental Air. The space over a hung ceiling used

for environmental air handling purposes is an example

of the type of space for which these actuators are

configured.

Installation

The M9208-GGx-x Series Proportional Electric Spring

Return Actuators mount directly to the surface in any

convenient orientation using two No. M3.5 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 included on the

actuator housing.

Parts Included

• M9208-GGx-x actuator

• M9208-603 adjustable stop kit

• M9000-604 anti-rotation bracket with two

No. M3.5 x 9.5 mm, pan-head, cross-recessed

(Phillips), self-drilling and self-tapping screws

• Manual override crank with 3M® Dual Lock®

adhesive-backed strip

• Two No. 10-32 x 9/16 in. conduit connector screws

Special Tools Needed

• 10 mm wrench/socket

• drill with Phillips bit, driver size 1

IMPORTANT: Use this M9208-GGx-x Series

Proportional 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: Before specifying M9208-GGx-x

Series Proportional Electric Spring Return Actuators

for plenum applications, verify acceptance of

exposed plastic materials in plenum areas with the

local building authority. Building codes for plenum

requirements vary by location. Some local building

authorities accept compliance to UL 1995, Heating

and Cooling Equipment, while others use different

acceptance criteria.

IMPORTANT: Do not install or use this

M9208-GGx-x Series Proportional Electric Spring

Return Actuators 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.

Mounting The M9208-GGx-x Series Proportional Electric Spring Return Actuators can be easily installed on dampers with round shafts from 5/16 to 5/8 in. (8 to 16 mm) or square shafts from 1/4 to 1/2 in. (6 to 12 mm) using the standard shaft coupler included with the actuator. An optional M9208-600 Large Shaft Coupler Kit adapts to larger shaft sizes; see Table 1 for more details. If the damper shaft extends less than 3.31 in. (84 mm), see the Removable Coupler section for further instructions.

! ! CAUTION: Risk of Property Damage. Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment. CAUTION: Risk of Property Damage. Insulate and secure each unused wire lead before applying power to the actuator. Failure to insulate and secure each unused wire lead may result in property damage.

Control Response The installation side of the actuator and the position of the mode selection switch combine to determine control response from the actuator. See Figure 14. Note: During normal operation, if the actuator stroke increases due to seal or seat wear, input signals are automatically reconfigured to the increased rotation range in approximately 0.5° increments. Installation Side 3.
