Cummins-3400196 Speed ​​Control Board Chinese Instruction

Function description:
The 3044196 speed controller is a fully electronic closed loop control design. It controls the engine's speed quickly and responsively for instant load changes. When connected to the matching EFC series electronic actuator and magnetic speed sensor signal, it can control the CUMMINS engine.
In terms of design, it is simple to install and pre-adjustable, including speed regulation and working idle speed, to assist in multiple machines, as well as to prevent inverse battery voltage, instant pulse voltage, actuator short circuit failure and protection in the absence of speed sensor signal or power supply, etc.

Installation and use:

Step 1 - Installation of 3044196:

1. According to the data below, it is recommended to use anti-slip self-locking screws for installation. The center distance of the four mounting holes is: 135mm×102mm, and the diameter of the mounting holes is 5.5mm
. 2. Connect one-to-one according to the following wiring methods:
1. 2:1 is the positive electrode of the DC power supply, and 2 is the negative electrode of the DC power supply.
3.4: It is the ACT (actuator) output port.
5, 6: It is the MPU (speed sensor) input port.
7, 8, 9: Fine-tune the external speed.
10: It is the idle switch port.
11: Public end.

Step 2 - 3044196 debugging:

When the power is turned off and the generator set is not running, adjust each fine-tuning to the initial position:
adjust the IDLE SPEED (idle speed) to the midpoint (fine-tuning is 20 turns in total, first counterclockwise to the bottom, then rotate clockwise for 10 turns).

Adjust the RUN SPEED (running speed) to the midpoint (fine-tune for a total of 20 turns, first counterclockwise to the bottom, then rotate clockwise for 10 turns).

Adjust GAIN (gain) to 20% to 50% (fine adjustment in one circle). Adjust DROOP (speed sag) to 0.

DROOP operation: Adjust DROOP until the required value between no load and full load, adjusting DROOP in a clockwise direction will increase.

Start the engine:

Adjust the speed potentiometer of the controller until the engine is operated at a predetermined rotation speed. Rotating clockwise increases engine speed. If the speed regulation system is unstable, the GAIN setting value is slightly reduced.
When the engine is no load, the GAIN is adjusted as follows:
slowly adjust the GAIN clockwise until the engine speed begins to swing.
Then slowly rotate counterclockwise to reduce the adjustment value of GAIN until the rotation speed stabilizes.

Note when synchronous operation (ISOCHRONOUS):
To use synchronous operation, you must first turn the DROOP button counterclockwise to the bottom before starting the setting.
The operation of the speed sag rate is controlled by the DROOP button. Rotating it clockwise will increase the speed sag rate; to set the value of the speed sag rate, first refer to the frequency obtained by the MPU and the rotation angle of the throttle actuator axis at no load to full load. If the MPU obtains a frequency of 4260Hz and the rotation angle of the throttle actuator axis is about 30 degrees between no load and full load, setting the DROOP button at 10 o'clock can provide about 4% of the velocity sag from the idle speed pulse to full load; while a lower electromagnetic speed pulse frequency or a smaller axis rotation angle will make the system speed sag even lower.

Special Note:

This description is standard 3044196 Chinese description, and there are significant differences in the parameters of non-standard products.
