GENERAL
The MP909 Pneumatic Damper Actuators are rollingdiaphragm, piston-type pneumatic damper actuators.MP909A, B, and C Actuators were manufactured with steelhousings and in many stroke length and spring rangecombinations. They were packaged with many differentmounting brackets and associated hardware. The MP909Dand E are manufactured with aluminum alloy housings and inonly two stroke lengths and four spring ranges. The MP909His an MP909E with a positive positioner providing adjustablestart point and 3, 5, or 10 psi (20, 35, or 70 kPa) span(operating range). An MP909E with a 5 to 10 psi (34 to 69kPa) spring range can be converted to an equivalentMP909H by adding the MP909E Positive Positioner RetrofitKit (see PARTS AND ACCESSORIES).
MP909D models replace most MP909A models and MP909Emodels replace most MP909B models. The MP918B replacesMP909C models.
APPLICATION
These actuators are used for proportional control of variable-volume terminal units, mixing boxes, and small- to medium-sized dampers. Figure 1 shows a typical damper controlapplication.

OPERATION
In a standard damper application, air from the branch line ofthe controller enters the chamber (2) of the MP909 (Fig. 3)through (1). On an increase in air pressure, the diaphragm (3)strokes the piston (4) against the opposing force of the spring(6) and damper. The stroke stops when the spring and piston/diaphragm forces are equal. On a decrease in air pressure,the spring returns the shaft, piston, diaphragm, and damperto their rest positions.

MAINTENANCE
General
Routine inspection of MP909 Actuators is recommended.
Operational Check
To assure smooth consistent system operation, make thefollowing checks:
1. Visually check that air tubing and bracket connectionsare tight and solid.
2. Check that damper blades, linkage, and actuator arefree from damage and not binding.
3. Check that dampers open and close fully whencontroller is adjusted to provide changes in air pressurethrough the full operating range of the actuator.
4. Check that linkage and other moving parts arelubricated.
Stroke Adjustment
The adjustable stroke option, available on some MP909Emodels for terminal unit applications, may be added to anMP909E by ordering two stops (see ACCESSORIES). To setstops for desired stroke see Figure 4. Tighten the band firmly(25 lb-in. minimum torque).

MP909A-EAND H PNEUMATIC DAMPER ACTUATORS
MP909H Positive PositionerStart Point Adjustment
Calibrated scale on the positioner setpoint knob allows 1.5 to13 psi (10 to 90 kPa) start point adjustment. The start point
setting is held by means of the pointer on the positioner coveragainst detents on the setpoint knob. Each detent changesthe start point approximately 1/4 psi (1.72 kPa).

TROUBLESHOOTING
Equipment Required
Pressure Bulb #852 or PRV with restriction.0 to 30 psi pressure gage.
Procedure
Disconnect controller from the actuator.Use a pressure bulb, Memphis Service Center #852, orinstall a PRV and a 0.005 or 0.007 in. restrictor in theline (Fig. 5).Install a pressure gage in the line as shown.Refer to Troubleshooting Flowchart (Fig. 6) for operationalproblem diagnosis

/!j CAUTIONGeneral
Diaphragm replacement for the MP909A, B, and C is the onlyfield repair recommended. MP909D, E, and H arepermanently sealed units and must be replaced with anotherunit if defective. A positive positioner retrofit kit is available forthe MP909E, 5 to 10 psi (34 to 69 kPa) spring range models(see ACCESSORIES). With the addition of the retrofit kit, theMP909E functions as an MP909H.
Diaphragm Assembly Replacement-MP909A-C
The diaphragm (Fig. 7) may be replaced without removing thefittings from the actuator or the actuator from the mountingbracket.
If the actuator is removed from the mounting bracket toreplace the diaphragm, leave the nut on the shaft. Thisprevents the spring from pushing the shaft back through thebearing and damaging the bearing.
