Rotary overshaft SmartX Actuators provide an economical and reliable solution for many overshaft damper and Schneider Electric VB2000 ball valve requirements. All products accommodate shaft sizes up to 1/2” (13 mm) in diameter.

Spring return models provide 30 in-lb (3.4 N-m) of torque in either two position, ﬂoating or proportional control. Non-spring return models provide either 35 in-lb (4 N-m) or 70 in-lb (8 N-m) in either ﬂoating or proportional control.

Features

• Two position models controlled by SPST controller

• Floating models controlled by SPDT ﬂoating controllers

• Proportional models controlled by 0 to 3 Vdc, 6 to 9 Vdc, 0 to 10 Vdc, 2 to 10 Vdc or 4 to 20 mAdc with the addition of a 500 ohm resistor. Control function direct/reverse action is jumper selectable

• Spring return models provide 30 in-lb (3.4 N-m) of torque

• Non-spring return models supply 35 in-lb (4 N-m) or 70 in-lb (8 N-m) of torque

Move the damper to its normal position. Verify the controller action is set to match the damper application.

Installation Instructions

Manual Override Operation

When necessary, the actuator’s output shaft can be repositioned using the manual override mechanism (Figure-10) as follows:

1. Disconnect power from the actuator. Spring return models will fully return to their normal position. Non-spring return

models will remain in position.

2. Insert the crank in the product. Without pushing in on the crank, rotate the manual override crank in the direction shown

by the arrow on the product label until the actuator rotates to the desired position. Push in until the mechanism locks in position. Non-spring return models do not have the locking feature.

3. If you desire to reposition a spring return actuator manually from a locked position, turn crank 1/8 turn counterclockwise

and pull out to release. Adjust position as desired.

4. If you desire to reposition a non-spring return actuator manually, turn the crank in either direction as needed until you

reach the desired position.

Caution:

• Only use manual override when the actuator drive motor is not powered.

• Engaging the manual override when the actuator is powered will cause damage to the gears.

• Using power tools to adjust the override will cause damage to the gears.

• Avoid manually repositioning the actuator beyond its adjustable travel limit setting.

Damper Mounting

Mx4D-xxxx-xxx SmartX Actuator Rotary Damper

Installation

Caution: Do not drill additional holes in the actuator body. Pre-drilled holes are located on gear plate side to accept #8-32 thread-forming screws for mounting accessories.

Note: The Mx4D-xxxx-xxx rotary actuators mount on shafts up to 1/2” diameter. Two set screws secure the actuator to the shaft.

Spring return models can be mounted from top or bottom. When mounting from the top, use AM-772 bracket. See Figure-12.

Normally closed damper: when damper is closed, actuator position indicator should be at 0°. When damper is open, actuator position indicator should be at 90°.

Normally opened damper: when damper is open, actuator position indicator should be at 0°. When damper is closed, actuator position indicator should be at 90°.

This step determines shaft rotation. Linkage may change damper direction.

Installation Instructions

Ball Valve Mounting

Installation of Mx4D-xxxx-xxx Actuators on 1/2” to 3” Schneider Electric VB2000 Ball Valves

Install the actuator onto the ball valve according to Figure-16.

Note: If space constraints do not allow the actuator to be installed in the standard position, reposition the mounting plate before mounting the actuator.

The valve should be mounted in a weather-protected area, in a location that is within the ambient temperature limits of the actuator. The installation of the actuator assembly should provide clearance on all sides to allow for any maintenance that may be needed (see Figure-13 thru Figure-15).

1. Follow the general piping practices.

2. Apply pipe sealant sparingly to all but the last two threads of a properly threaded, reamed, and cleaned pipe. Make sure

the pipe chips, scale, etc. do not get into the pipe since this material may lodge in the valve seat and prevent proper operation of the valve. The valve must be piped with an inlet and an outlet.

3. Start the joint hand-threading the pipe into the valve. If the thread alignment feels normal, continue to turn the pipe by

hand as far as it will go.

4. Use a pipe wrench to fully tighten the pipe to the valve.

5. Caution: Do not over-tighten the pipe, which may cause stripped threads. Avoid twisting or crushing the valve while tight-

ening the pipe.

6. Insulate only the valve body and associated piping. Do not insulate the actuator.

7. In chilled or cold water systems where the environment is humid, use a drip pan under the valve to catch condensate.

Caution: The Schneider Electric SmartX Actuator is designed to effectively support its own weight. No load or weight should be resting on the actuator. Long term damage may occur to the actuator, mounting connection, or valve.

• Do not insulate the actuator/linkage. Doing so will result in excess heat buildup within the actuator.

• For non-steam applications the ball valve assembly must be mounted so the actuator is at least 5° above horizontal (Figure-13) to ensure that any condensate that forms will not travel into the mounting bracket or actuator.

• On steam applications, the ball valve assembly must be mounted approximately 45° from horizontal (Figure-14).

• Temperature Restrictions: To maintain the maximum ambient temperature 140 °F (60 °C) of the actuator/valve, the maximum allowable ﬂuid temperature should not exceed the 250 °F(121 °C) ball valve maximum rating.

Checkout

With the correct control signals applied, power the actuator. Observe movement of the output shaft to check for proper operation. If a spring return model, removing power should cause the actuator to spring return to its rest position. If problems are encountered, check the suggestions below.

Note: Check that the transformer(s) are sized properly.

• If a common transformer is used with multiple actuators, make sure that polarity is observed on the secondary. This means connecting all black wires to one leg of the transformer and all red wires to the other leg of the transformer.

• If multiple transformers are used with one control signal, make sure all black wires are tied together and tied to control signal negative (-).

• If the controller uses a full-wave power supply and does not provide isolated outputs, a separate transformer is required to power the actuator.

Installation Instructions

Theory Of Operation

The MA series SmartX Actuators provide two position spring return operation. They are equipped with a mechanical spring return mechanism. When power is applied, the actuator moves to its powered position, at the same time tensing the spring return safety mechanism. When power is removed, the spring returns the actuator to its normal position (retracted). The spring return system provides consistent close-off for sensitive damper or valve applications.

MA series two position actuators use a brush DC motor controlled by on-board electronics. When the actuator encounters a stall or end of travel position, the motor current is automatically reduced, preventing damage to the actuator or motor.

MF or MS series ﬂoating or proportional SmartX Actuators use a brush DC motor which is controlled by a microprocessor. The microprocessor supplies the intelligence to provide a constant speed and to know the actuators exact position. The microprocessor monitors and controls the DC motors rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition.

All actuators may be stalled anywhere in their normal rotation without the need of mechanical end switches.

Maintenance

Regular maintenance of the total system is recommended to assure sustained optimum performance. The Linear series actuators are maintenance free.

Field Repair

None. Replace with functional actuator.
