M9108, M9116, M9124, and M9132 Series

Electric Non-Spring Return Actuators

Installation

IMPORTANT: Use this M9108, M9116, M9124,

or M9132 Series Electric Non-Spring Return Actuator

only to control equipment under normal operating

conditions. Where failure or malfunction of the

actuator could lead to personal injury or 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 actuator.

IMPORTANT: Utiliser ce M9108, M9116,

M9124, or M9132 Series Electric Non-Spring Return

Actuator uniquement pour commander des

équipements dans des conditions normales de

fonctionnement. Lorsqu'une défaillance ou un

dysfonctionnement du actuator risque de provoquer

des blessures ou d'endommager l'équipement

contrôlé ou un autre équipement, la conception du

système de contrôle doit intégrer des dispositifs de

protection supplémentaires. Veiller dans ce cas à

intégrer de façon permanente d'autres dispositifs,

tels que des systèmes de supervision ou d'alarme,

ou des dispositifs de sécurité ou de limitation, ayant

une fonction d'avertissement ou de protection en cas

de défaillance ou de dysfonctionnement du actuator.

Parts Included

All Models

M9124- and M9132-AGC Models

Includes three M9000-105 pluggable 3-terminal blocks.

Special Tools Needed

• torque wrench with 10 mm socket

• digital voltmeter

Mounting

IMPORTANT: The actuator is intended for

indoor mounting only, with no direct exposure to

water beyond NEMA 2 conditions. Use an

appropriate shield or enclosure where the

environment exceeds NEMA 2 specifications.

Mount M91xx Series actuators in any convenient

orientation. Install the actuators on a 3/8 to 3/4 in.

(9.5 to 19 mm) round shaft or a 3/8 to 5/8 in.

(9.5 to 16 mm) square shaft, 2 in. (51 mm) or longer.

If the shaft is less than 2 in. (51 mm) long, install an

extension recommended by the damper or valve

manufacturer. Use the M9000-154 1 in. Jackshaft

Coupler Kit for 1 in. (25.4 mm) outside diameter shafts.

To mount the actuator, proceed as follows:

1. Press and hold the gear release lever, and rotate

the coupler to the 0 or 90° position. Release the

gear release lever. (See Figure 1.)

Note: To change the rotation range on: • -xGC models with auxiliary switches, one or both of the switches may need adjustment. See the Auxiliary Switches (xGC Models) section. • -HGx models with zero and span potentiometers, adjust both potentiometers. See the Potentiometers (HGx Models) section. Feedback Signal For AGD and AGE models, resistance feedback is reduced corresponding to the reduced rotation range.

Terminal Block 1 1 2 ~ + 3 ~ + ^COM CW CCW 24 VAC 24 VDC 1 ^- 2 3 ~ + + ~ COM CW CCW Through the Conduit Openings Depending on the M91xx Series model selected, use one or both conduit openings. The threaded actuator conduit openings accept 1/2 in. trade size conduit fittings. Refer to Figure 6 and proceed as follows: 1. Loosen the cover screw with a Phillips No. 1 screwdriver, and remove the actuator cover.

Models with the same torque and control input may be mounted in tandem. For example: • Terminal 102 from the master actuator to Terminal 102 on the slave actuator. • M9116: two GGx, two HGx, or one GGx and one HGx • Terminal 103 from the master actuator to Terminal 103 on the slave actuator. • M9124: two AGx, two GGx, two HGx, or one GGx and one HGx • M9132: two AGx or two GGx Note: Do not use M9108 Series models in tandem. The Master/Slave Jumper is factory set in the master position.

3. Connect the input control signal: • For AGx models, connect the input control signal to the common, CW, and CCW terminals on both the master and the slave actuators. (See Figure 7.) • For GGx and HGx models, connect the control signal to the master actuator, and connect 24 VAC/VDC power to both the master and slave actuators. IMPORTANT: For proper tandem operation, do not connect the control input to the slave unit.
PAGE 7
Adjusting the Zero and Span To adjust the zero and span potentiometers on the HGx models: 1. Verify that Jumper W2 is in the 0 to 10 VDC position, and provide 24 VAC or 24 VDC power to Terminal 1 (Common) and Terminal 2. 2. Connect the Common from the controller to Terminal 1, and either a voltage signal to Terminal 5 or a current signal to Terminal 4. 3. Connect Terminal 1 and Terminal 3 to a voltmeter to monitor the calibration output. 4. Use a 1/8 in.
