12V Electronic Actuator ADC225-12V For Diesel Generator Parts
Description
The 12V electronic actuator is made of metal, which is strong and durable. The 225 Series actuator is a rotary output, linear torque proportional electric servo designed for mechanical actuation of fuel system control levers. It is energized by appropriate speed control unit signals and is capable of 25 degrees of rotation.
Key Features
Adjustable Function: The linkage can be optimized by adjusting for an actuator current difference from no engine load to full engine load of approximately 2 amps for 12-volt systems. The no-load current is altered by varying the length of the linkage and the range is adjusted by changing the hole used by the rod end bearing on the actuator lever.
Lever Design: It allows you to easily push the engine to the maximum full fuel position before starting it, and can smoothly return to the minimum fuel position, so as to achieve safe and stable operation.
Strong and Durable: Made of metal with high strength and good rigidity, it can resist wear, corrosion, heat, shock, and deformation, allowing it to be used for a long time.
Complete Installation Tools: The package includes a lot of necessary tools, which can facilitate the installation.
Quick Response: Smaller angles of actuator travel may improve transient performance, but will reduce the force available at the fuel control lever. Adjusting the actuator to operate through at least one-half of its stroke (12 degrees) will provide near optimum response.
Compact: It is compact (5.2*4.3*4.8inch), so you can easily move it.
Protective Packaging: This product comes in a custom foam that resists compression and falls to prevent product damage in transit.
Guaranteed Customer Service: We aim to provide quality products and services. If you have problems, please feel free to contact us. We will reply and solve the problem for you as soon as possible.
Details
Round Corners: The round corners can prevent scratching your hands.
Smooth Surface: It has a smooth surface, so you can wipe it with a wet cloth.
Application
It applies to diesel generator sets.

Working Principle
The electromagnetic speed sensor generates an electrical signal that is proportional to the engine speed setting. If the signal is not proportional to the engine speed, the current change from the speed control unit to the actuator will change the magnetic force in the actuator. Then, the rotation of the actuator shaft will adjust the fuel of the engine and make the engine speed equal to the preset engine setting. The shaft rotation is proportional to the actuator current and is balanced by an internal spring.
Troubleshooting
Red to White (12V) 1.25ohms
Red to Housing Infinity
White to Housing Infinity
Energize the actuator to full fuel (follow the steps in the control unit publication) and manually move the actuator through its range. No binding or sticking should occur. If the actuator passes these tests, the problem is elsewhere in the system.
Installation
The actuator must be rigidly mounted as close as possible to the engine throttle lever. When selecting the mounting location, consideration must be given to possible linkage obstructions.
The linkage should be direct, short, and as light as possible. Low-friction rod end bearings should be used throughout the linkage system.
The linkage should be adjusted so that the fuel control minimum fuel and maximum fuel stops are used rather than the internal actuator stops.
A. Drill the actuator mounting holes in a pre-fabricated mounting bracket. The position of the actuator on the mounting bracket should insure minimal misalignment between each end of the governor system linkage. The linkage ball-bearing rod ends can tolerate a maximum misalignment of 10 degrees.
B. Affx the actuator bracket to the selected location on the engine.
C. Attach the actuator securely to the mounting bracket.
D. Adjust and secure the linkage rod and rod end bearings.
For proportional actuators to operate with linear control systems, it is important to obtain a linear relationship between actuator stroke and fuel delivery.

Notes
- For diesel fuel systems, the linkage configuration is typically linear. The actuator lever should be nearly parallel to the fuel control lever and perpendicular to the linkage rod at the mid-fuel position.
- The wiring must be capable of handling typical current levels of 8 amps for 12-volt systems without experiencing a significant voltage drop. Larger gauge wire will be necessary for cable lengths greater than 10ft.
- The actuators with 2-pin connectors are prewired for 12. Use the included harness to connect the actuator to the speed control unit.
- Upon release, recheck the linkage to insure both the linkage and the levers are securely fastened and that no binding is present.
- Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before ordering.
- We maintain high standards of excellence and strive for hundred percent customer satisfaction. Feedback is very important to us. We hope that you contact us immediately before you give neutral or negative feedback, so that we can address your concerns. It is impossible to address issues if we do not know about them!
