Linkage Assembly

Damper

Note: Each actuator in the MP-553X series is provided with a factory-installed damper linkage. No separately-ordered linkage is required.

Caution: Do not twist or exert any force on the actuator housing during installation. Either turn the base by hand or, if necessary, use a 1-5/8" open-ended wrench (TOOL-37) on the

flats provided on the actuator base, or on the valve body mounting nut. (Refer to Figure-2)

1. Determine the best mounting position for the actuator as follows: a. Determine, from the system requirements, if the damper should spring-return to the

open position (Figure-12) or closed position (Figure-13) whenever power is lost to

the actuator. For example, an outside air damper actuator is typically linked so as to retract (spring-return) to the damper’s fully closed position (safe position).

b. Be sure to allow adequate working space around the actuator mounting location to mount the actuator, link it to the damper, and wire it into the system (refer to

Figure-16).

c. If possible, select a mounting position such that, at mid-stroke, the actuator crank arm and the damper crank arm on the drive shaft are each at a 90

°

angle to the

damper rod (refer to Figure-14). This is the recommended mounting position. It may

be necessary to swivel the actuator linkage to arrive at this mounting location.

d. Consider the damper rod length when positioning the actuator in relation to the damper. A damper rod that is too long is not rigid enough to provide good control, while a damper rod that is too short makes adjustment difficult.

2. Position the actuator on the duct and mark the location of the mounting holes, using the

actuator mounting bracket as a template (refer to Figure-16).

3. Drill or punch the mounting holes in the duct for the appropriate 1/4" (6 mm) diameter screws or bolts. The actuator must be mounted firmly enough to prevent excessive actuator movement under normal damper loading. If there is excessive actuator movement, the damper may not fully open or close.

4. Mount a ball joint connector in the slot on the damper crank arm. To achieve 90° of damper rotation, position the connector 1-1/2" (38 mm) from the centerline of the shaft hole on the crank arm. For 60

° of damper rotation, position the connector 2" (50 mm) from the shaft hole centerline. Typically, 60° to 70

°

of rotation (maximum is 90

°

) is

sufficient to permit almost maximum air flow through the dampers. Refer to Figure-14.

5. Rotate the damper to its open position. Install and secure the damper crank arm (with ball joint connector) to the damper shaft, positioning the crank arm as follows (refer to

Figure-14):

a. To achieve 60

°

of damper rotation, position the crank arm so that it is pointed towards the actuator at 30° from its mid-stroke position.

b. To achieve 90° of damper rotation, position the crank arm so that it is pointed towards the actuator at 45° from its mid-stroke position.

6. Install the damper rod by sliding one end through the ball joint connector mounted on the damper crank arm, and the other end through the straight connector on the actuator crank arm. Tighten the nut on the actuator crank arm’s straight connector. Cut off any excess length of damper rod.

7. For normally open dampers, tighten the nut on the ball joint connector on the damper crank arm. To ensure that the damper closes completely, make adjustments so that the actuator is 1/16" (1.6 mm) from the extended end of stroke when the damper closes.

Verify and, if necessary, make final adjustments during system checkout.

8. For normally closed dampers, rotate the damper crank arm until the damper is closed.

While holding the damper closed, tighten the nut on the ball joint connector on the damper crank arm. To ensure that the damper closes completely, make adjustments so that the actuator is 1/16" (1.6 mm) from the retracted end of stroke when the damper closes.

Final adjustment of the actuator and damper must be performed when the system is powered and functioning. Refer to the CHECKOUT section to ensure that the damper is linked correctly.

Valve

For valve assembly details refer to AV-600, Valve Linkage Kit General Instructions,

F-26279 or AV-601, Linkage Extension Kit General Instructions, F-26280 . Refer to

Figure-17 for external dimensions of the valve actuator.

F-25856-5

CHECKOUT

After the entire system has been installed and the actuator has been powered up, perform the following checks for proper system operation.

Caution: Never power the actuator without a spring return linkage attached.

Positioning with

Controller

If the sensed media is within the controller’s setpoint range, the actuator can be positioned by adjusting the controller setpoint up and down. Check for correct operation of the actuator

(valve or damper) while the actuator is being stroked.

Go, No-Go Test

1. Apply power to the actuator. The actuator motor should run and the actuator shaft should extend.

2. Remove power from the actuator. The actuator motor should stop running and the actuator shaft should spring-return to the retracted position.

THEORY OF OPERATION

Refer to Figure-15. The permanently sealed, oil-filled case contains a movable hydraulic

piston assembly and an electric pump/motor for the hydraulic system. The electric pump/motor is powered by the input supply voltage and runs continuously, generating a fluid pressure which is transmitted to the top of the piston. This fluid pressure creates a hydraulic force which drives the piston downward. Opposing the hydraulic force is the spring of the valve or damper linkage. When the hydraulic force becomes great enough to overcome the opposing spring force, the piston translates downward, extending the output shaft.

The pump/motor contains a transformer winding which provides power to the Vdc power supply. The power supply, in turn, provides power to the transducer assembly. To proportionally position the shaft, first the control signal (2 to 15 Vdc) input is compared to the shaft position feedback signal, through the actuator controller circuit. Then, the actuator controller circuit emits an output signal which positions the flapper in the transducer. The flapper opens or closes further to decrease or increase the hydraulic pressure above the piston, resulting in an upward or downward movement at the shaft.

MAINTENANCE

TROUBLESHOOTING

The actuator is sealed in oil and requires no maintenance.

Regular maintenance of the total system is recommended to assure sustained, optimum performance.

FIELD REPAIR

Caution: Never power the actuator without a spring return linkage attached.

Use the following steps to locate malfunctions:

1. Check the actuator by applying the proper supply voltage.

2. The motor should run when power is applied. If it does not run, the actuator is inoperative and should be replaced.

3. While the motor is running, apply 10 Vdc to the Yellow and Blue wires and the actuator should extend. If it does not extend, check the mechanical linkage for any damage or misadjustment which could prevent the actuator from extending. If the mechanical linkage is inoperative, adjust the linkage or replace the damaged components, as applicable. If the mechanical linkage moves correctly and freely, the problem lies in the actuator and it must be replaced.

4. Disconnect the 10 Vdc from the Yellow and Blue leads. The actuator should return to the fully retracted position.

5. If applying power directly to the actuator results in correct operation of the actuator, the actuator and linkage are functional, and the problem lies in the wiring or thermostat.

Repair or replace the wiring or thermostat, as applicable.

None. Replace an inoperative actuator with a functional unit.
