Application

The MPR-5600 series and MPR-5700 series actuators are

used for electronic proportional control of dampers and

valves which require a return to the normal position upon

power interruption. MPR-5600 series actuators are

compatible with controllers generating 4 to 20 mA input

signals, and MPR-5700 series actuators are compatible

with 135 Ω slidewire controllers (Series 90).

Mounting 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 the valve body mounting nut. Refer to Figure-4 . Housing Base Wrench Flats Figure-4 Housing and Base Location. Dampers The actuator is not position sensitive. It can be mounted in any position in an NEMA Type 1 location.

Refer to Table-4 for the maximum length of run for the power leads, for the given wire size(s). To determine the allowable maximum power lead run when wiring multiple actuators, divide the maximum run shown in Table-4 by the number of actuators on the run. Refer to Figure-5 for further details.

Wire Lead Connections (No Conduit) Make connections as required. Refer to Figure-1 through Figure-3 to determine your particular application. Refer to Table-5 to determine the damper position versus the input signal. Refer to Figure-6 for a view of the actuator. Note: The cover plate and screw supplied with the actuator are not required with this method. Figure-6 Connection of Wire Leads (No Conduit). Table-5 Damper Position Versus Input Signal.

Note: As shown in Figure-11 , the hole in the cover plate of the actuator conduit housing is sized to accept both British standard M20 (20 mm) conduit connectors and 20 mm-to-PG16 adaptors for use with DIN PG16 connectors. (Follow the steps for installing the conduit box to the actuator.) Linkage Assembly Damper Note: Each actuator in the MPR-5X3X series is provided with a factory-installed damper linkage.

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-16 ): 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.

6. Reconnect the actuator wires to the controller. 7. Remove power from the actuator. THEORY OF OPERATION Refer to Figure-17 . 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.
