General Instructions

Application

The MA-5200 series and MA-5300 series actuators are

used for two-position control of valves and dampers

which require a return to the normal position upon

power interruption.

• An actuator with the part number suffix "-500" has a

built-in, adjustable, SPDT auxiliary switch

• Available in damper models or base models that

require damper or valve linkage

• Die cast lower housing with 1/2" conduit opening

and painted steel upper housing

Mounting 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" (41 mm) open-ended wrench (TOOL-37) on the flats provided on the actuator base or the valve body mounting nut. Refer to Figure-2. Housing Base Wrench Flats Figure-2 Housing and Base Location. Dampers The actuator is not position sensitive. It can be mounted in any position in a NEMA Type 1 location.

Figure-4 Connection of Wire Leads (No Conduit). Installing 3/8" Flexible Conduit Onto One or Both Sides of Actuator Flexible conduit may be installed onto one or both sides of the actuator (refer to Figure-6 and Figure-7). Install each conduit as follows: 1. Determine the side of the actuator to which the flexible conduit is to be attached. 2. Remove the knockout (e.g., with channel lock pliers) on the selected side of the actuator. Refer to Figure-5. 3. Make the required connections.

Linkage Assembly Damper Note: Each actuator in the MA-5x3x 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" (41 mm) open-ended wrench (TOOL37) on the flats provided on the actuator base, or on the valve body mounting nut. (Refer to Figure-2.) 1.

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-21 for external dimensions of the valve actuator. Adjustments Auxiliary Switch (MA-5xxx-500) The switching point is adjustable over the entire actuator stroke and is pre-set at the factory to close the N.C. contacts at the retracted end of stroke.

THEORY OF OPERATION Refer to Figure-16. The permanently sealed, oil-filled case contains a movable hydraulic piston assembly and an electric pump for the hydraulic system. The pump generates a fluid pressure which is transmitted to the top of the piston, creating a hydraulic force which drives the piston downward. Opposing the hydraulic force is the spring of the valve or damper linkage.
