Installation Instructions M91xx

Issue Date October 6, 2003

M9108, M9116, M9124, and M9132 Series

Electric Non-Spring Return Actuators

Installation

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.

IMPORTANT: The M91xx Series actuators are

intended to control equipment under normal

operating conditions. Where failure or malfunction of

an M91xx Series actuator could lead to an abnormal

operating condition that could cause personal injury

or damage to the equipment or other property, other

devices (limit or safety controls) or systems (alarm

or supervisory) intended to warn of, or protect

against, failure or malfunction of the M91xx Series

actuator must be incorporated into and maintained

as part of the control system.

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.)

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.

Rotate the coupler fully closed to fully open to verify that the damper and actuator rotate freely throughout the range. Rotation Range The actuator is factory set for 0 to 90° rotation. To change the rotation range to less than 90°, use the top scale on the actuator cover, refer to Figure 3, and proceed as follows: 1.

Feedback Signal For AGD and AGE models, resistance feedback is reduced corresponding to the reduced rotation range. Refer to Figure 5 for the applicable M91xx actuator. Terminal Block 1 For the GGx, HGx, and JGx models, changing the rotation range changes the feedback signal and the operating range proportionally.

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: Models with the same torque and control input may be mounted in tandem. For example: • 1. Loosen the cover screw with a Phillips No. 1 screwdriver, and remove the actuator cover.

AGx Models To set one of these models for RA operation, reverse the control wiring connections at Terminal 2 and Terminal 3. (See Terminal Block 1 in Figure 5.) GGx, HGx, and JGx Models To set one of these models for RA operation, proceed as follows: 1. Press and hold the gear release, rotate the actuator coupler until it is in the full CW position, and release the gear release. 2. Move Jumper W1 from the factory-set DA position to the RA position. (See Figure 8.) 3.
