ESD5500E Diesel Generator Governor Speed Controller Engine Actuator Magnetic Speed Sensor DC Motor Control Board Genset Parts

[Speed Controller]

Application Scope: The ESD5500E series speed controller is suitable for all GAC-compatible control drives, except ACB2000 electronic control drives.

Features: Easy installation, high anti-interference capability and compatibility with other control devices, adjustable starting power, and slow acceleration function; minimal starting black smoke, actuator short-circuit protection, anti-battery reverse connection protection, instant voltage and speed loss signal safety protection, etc.

Parameters:

Operating Environment: Temperature -20℃ to +85℃, relative humidity 95%.

Input Voltage: 12VDC or 24VDC power supply

Speed Signal: 0.5–120V RMS magnetic speed sensor

Output Current: 0–10A DC square wave (continuous)

Fine Adjustment Range: ±200Hz, 5K potentiometer

Connections:

A-B: Actuator, 1.5 mm² shielded cable, shielding layer connected to the housing.

C-D: Speed Sensor, 1.0 mm² shielded cable, shielding layer connected to the housing.

E-F: Battery, 1.5 mm² cable, E connected to negative terminal and housing, F connected in series with a 10A fuse to positive terminal.

G-J: 1.0mm² trim potentiometer cable, 5K potentiometer, speed range ±200Hz (can also be used without shielding)

G-M: 1.0m² shielded cable with ground connection; closed for no-load operation, open for high-speed mode (not connected for high-speed operation)

G-H: short connection for setting speed range (generally not used)

K-L: adjustable rate via 1.0mm² cable, two-point short-circuit connection with adjustable percentage rate, separated rate adjustment at 0%

N: 3–10VDC input for speed control (negative terminal and E connected), commonly used for devices and automotive applications

P: 10VDC, 100mA power output

Adjustment:

I. Start the device at no-load speed

1. G-M is short-circuited for idle speed, set the 'IDLE' potentiometer to clockwise upward rotation, counterclockwise downward, adjust to approximately 650 rpm, and set the starting position at 45%.

2. G-M is clamped for operation; set to high speed, adjust the 'SPEED' potentiometer clockwise upward and counterclockwise downward.

3. Potentiometer 'SPEED RAMPING', adjusts the time from no-load to high speed; clockwise setting for longer ramp time, counterclockwise for shorter ramp time, default position at 50%.

4. "STABILITY" Stabilizer Potentiometer: Set the optimal stability. If the oil is unstable, it can be adjusted to a starting position of 30%.

5. The "GAIN" boost potentiometer, used to adjust the response time of the oil motor, can be properly set when touring at 30% output position.

6. "DROOP" Rate Potentiometer, K-L short for "K-L", adjust the drop speed to 2.5%, with the starting position set at 40%.

II. Start the device at high speed

1. Disconnect G-M, start the diesel engine, and then the device will immediately accelerate to high speed.

2. The "FUEL" starting fuel potentiometer, which adjusts the starting fuel supply, allows for even rotation of the main fuel supply to promote smooth starting; the reverse rotation of the minor fuel supply reduces black smoke during startup, with an initial position set at 50%.

3. Other settings as above

【Sensor】
