Step 1: Check the oil pressure sensor function

1. Safe operation: First shut down the generator set and disconnect the power

2. Locate the sensor: Find the oil pressure sensor inside the unit

3. Function test:

-Remove the sensor

-Touch one end of the sensor to the metal door hook (as a ground)

-Slowly swing the float rod from the lowest point to the highest point

-Observe the change in the controller display value

Result analysis:

-Change: The basic function of the sensor is normal, proceed to the second step of inspection

-No change: The sensor may be faulty and needs to be replaced

Step 2: Calibrate the controller display value

If the sensor test is normal but the display is inaccurate (such as only showing 53% at the highest):

1 .Enter the controller settings menu:

-General Chinese brand controller: Select setting 78

-SMARTGEN brand controller: Select setting 94

2. Adjust the parameters to the correct values according to the video tutorial

3. Save the settings and restart the controller to verify

Professional advice

1. Regular calibration: It is recommended to calibrate the sensor and controller every 6 months

2. Environmental factors: Extreme temperatures may affect sensor accuracy

3. Accessory quality: Use original sensors to ensure compatibility
