TAC 1354 Clifford Avenue P. O. Box 2940 Loves Park, IL 61132-2940 www.tac.com MP-3xx Series, MP-4xx Series, MP-2xxx Series, and MP-4xxx Series Reversible and Proportional Electric Actuators General Instructions Application The MP series actuators are used for two-position, floating, and proportional control of dampers, valves, and program switches in heating, ventilating, air conditioning, and similar applications. Hazardous location models offer a sturdy cast aluminum case with bolted cover.
SPECIFICATIONS Actuator Inputs Input Control Signals: Refer to the actuator selection tables beginning on page 3 for input control signal capability versus specific actuator models. Floating, Requires one Single Pole Double Throw (SPDT) switch with floating (center off) position rated at 0.9 amps @ 24 Vac or two Single Pole Single Throw (SPST) switches rated at 0.9 amps @ 24 Vac. Two-Position, SPDT Requires snap acting switch rated at 0.9 amps @ 24 Vac. SPST Can be used with certain spring return actuators.
Actuators in the actuator selection tables below with “-600” suffix have the CP-8301-120 factory installed. All CP-8301s have a fixed span of 3 Vdc to drive the actuator full stroke and a start point adjustable from 2 to 12 Vdc (factory set 6 Vdc). F-15479-8 The CP-8391-91x series have a fixed range of 4 to 20 mAdc to drive the actuator full stroke. Refer to CP-8391-910 Series 4 to 20 mA Electronic Actuator Drive General Instructions F-22453.

European Standard EN 55022 Refer to Table-2 and Table-3 to identify applicable models. Warning: This is a Class A (European Classification) product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures. MOUNTING Preferred mounting is with the actuator in an upright position in a weather protected area. Note: The MP-21xx series requires upright mounting.

WIRING The wiring connectors are made to coded screw terminals. Actuators with “-600” suffixes also have 6" (152 mm) color coded leads for control circuit. Hazardous Location Models Hazardous Location Models Make all electrical connections to the assembly in accordance with the job wiring diagram, the National Electric Code Article 500, and in compliance with the local electrical codes. Two 3/4" pipe tapped openings are provided in the housing for rigid conduit connections.
Power Wiring Table-9 All actuators include a barrier that separates the power wiring compartment from the low voltage wiring compartment. Refer to Table-9 for allowable circuit class for the two wiring compartments. Actuator Circuit Class. Power Wiring Compartment Typical Part Numbers Actuator Description Low Voltage Wiring Compartment Terminals (Function) Circuit Class for Power Wiring Compartment Terminals (Function) Circuit Class for Low Voltage Wiring Compartment 1.
Control Wiring Refer to Figure-3 through Figure-23 for typical wiring of the actuators. Refer to the actuator selection tables beginning on page 3, for an index of External Wiring Figures versus actuator models and control signals. The requirements for the field control wiring are shown below. SPST Control Signal Refer to Figure-3 and Figure-4. Since the SPST switch is controlling the power to the actuator, the control wiring is limited to the power wiring shown above.
ADJUSTMENTS Limit Switch Adjustment The counterclockwise limit switch on certain actuators provides adjustable travel of 45° to 320° rotation. The actuator selection tables beginning on page 3 identify the models that have adjustable travel limits. To adjust travel refer to Figure-37 and Figure-38 while following the steps shown below. Note: The feedback potentiometers in the actuator have a fixed rotation (typically either 90° or 180°).
4. Insert a screwdriver through the access hole and engage the notched cam nearest the front of the actuator. Access Hole Figure-38 Limit Switch Adjustment. 5. Turning the cam CW (as seen from the front of the actuator) increases the length of the actuator rotation. Each click of the cam represents about a 3° change in actuator rotation. 6. After adjusting the cam, check the rotation of the actuator by shorting actuator terminal x to terminal 3 to drive the actuator to its new CCW limit setting. 7.
4. Insert a screwdriver through the plastic funnel shield, if present, and through the access hole, engaging the screwdriver with the gear-like plastic disc. Figure-39 Auxiliary Switch Adjustment (Rear View with Top and Back Covers of Actuator Removed). 5. Turning the disc CW (as viewed from the front of the actuator) causes the switch to operate nearer to the CCW end of actuator rotation. Each click of the cam represents about a 3° change in the switch point. 6.
CHECKOUT After the entire system has been installed and the actuator has been powered up, the following checks can be made for proper system operation. GO, NO GO Test Slidewire Controller with 24 Vac Actuators Refer to Figure-14. 1. Disconnect field wiring from Brown lead of AE-504 and terminals 7 and 8 of the actuator. 2. Apply 24 Vac power to terminals H and G of the actuator. 3. Short the Brown lead of AE-504 to terminal 7 of actuator and the actuator should rotate CW to its limit. 4.
8. Short actuator terminal X to 3 and the actuator should rotate CCW to its limit. If the unit passes steps 7 and 8, the actuator is good and CP-8301-xxx is defective. If the unit does not pass steps 7 and 8, the actuator is defective and the CP-8301-xxx may be good. CP-8301-024, Vdc Interface (TAC System 8000) with 24 Vac Actuators Refer to Figure-17. 1. Disconnect field wiring from Red, Yellow, and Blue leads of CP-8301-xxx. 2. Apply 24 Vac power to terminals H and G of the actuator. 3.
Positioning the Actuator with the 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 proper operation of the actuator (valve or damper) while the actuator is being stroked. Manually Positioning with Calibration Kit TOOL-201, Calibration Kit for TAC System 8000, Vdc Input Refer to Figure-16 through Figure-18. 1. Disconnect the field wiring from the Red, Yellow, and Blue leads of CP-8301-xxx. 2.
