Setup

1. Unpacking: Carefully remove all components from the packaging. Verify that all items listed in the "What's in the Box" section are present.
2. Placement: Place the machine on a stable, level surface in a well-ventilated area, away from direct sunlight or heat sources.
3. Power Connection: Connect the power cable to the machine's power socket and then to a compatible 110V/220V AC power outlet.
4. Fluid Filling:
   • Open the filling inlet and carefully pour the recommended test liquid into the fuel tank. Ensure the liquid level is within the specified range on the level gauge.
   • For ultrasonic cleaning, add appropriate cleaning liquid to the ultrasonic bath.
5. Injector Installation: Select the correct adapters for your injectors. Install the injectors into the test bench, ensuring a secure fit to prevent leaks.
6. Signal Cable Connection: Connect the pulse signal cables from the machine to each injector.

Operating Instructions

Ultrasonic Injector Cleaning

The ultrasonic cleaning function effectively removes carbon deposits and blockages from injectors.

1. Place the injectors into the ultrasonic cleaning bath.
2. Ensure the cleaning liquid covers the injector nozzles.
3. Select the "Ultrasonic Cleaning" function from the control panel.
4. Set the desired cleaning time (adjustable from 0-10 minutes).
5. Press "START" to begin the cleaning process.
6. For reverse flushing, install the injectors in the opposite direction after initial cleaning and repeat the process.
7. Note: Only 12V injectors are supported for ultrasonic cleaning. 70V and 120V injectors are not supported for this specific function.

Injector Testing Modes

The CT400 offers 10 testing modes to simulate various driving conditions and diagnose injector performance, including uniformity, atomization, sealing, and injection angle.

Available test modes:

1. Idle Test (0-20 ms): Simulates engine idling conditions.
2. Medium-Speed Test (0-7.5 ms): Simulates moderate engine speeds.
3. High-Speed Test (0-4 ms): Simulates high engine speeds.
4. Accelerating Test: Simulates rapid acceleration.
5. Shifting Speed Test: Simulates gear changes.
6. Leak Checking Test: Checks for fuel leaks from the injectors.
7. Idling Spray Value Test: Evaluates spray pattern and volume at idle.
8. Medium Speed Spray Value Test: Evaluates spray pattern and volume at medium speed.
9. High Speed Spray Value Test: Evaluates spray pattern and volume at high speed.
10. No-Disassembly Cleaning: Requires connection to C100 special parts for cleaning the combustion chamber or throttle (external accessory).

To perform a test:

• Select the desired test mode from the "FUNCTIONS MENU" on the control panel.
• Adjust "FUNCTIONS/PULSE WIDTH ADJUSTMENT" and "WORKING TIME / INJECTING TIMES" as needed using the up/down buttons.
• Press "START" to begin the test.
• Observe the spray pattern, atomization, and volume in the test tubes.
• Press "STOP" to end the test.

GDI, EFI, FSI & Multi-voltage Options

The CT400 is compatible with various injector types and offers multiple voltage outputs to drive different injectors.

• The machine supports standard injectors, GDI (Gasoline Direct Injection), EFI (Electronic Fuel Injection), and FSI (Fuel Stratified Injection) systems.
• Use the voltage selection buttons (12V, 70V, 120V) to match the voltage requirements of the injectors being tested.
• This compatibility extends to vehicles from Mercedes-Benz, BMW, Audi, Porsche, Ford, and other direct injection engines.

Maintenance

• Fluid Management: Regularly check the level and condition of the test and cleaning liquids. Replace or recycle test liquid as per local environmental regulations.
• Cleaning: After each use, clean the test tubes and ultrasonic bath to prevent residue buildup. Use a soft cloth and appropriate cleaning agents.
• Component Inspection: Periodically inspect all hoses, adapters, and electrical connections for wear, cracks, or damage. Replace consumable parts such as O-rings and seals as needed.
• Storage: Store the machine in a clean, dry environment when not in use. Utilize the portable drawer for organized storage of accessories to prevent loss or damage.

Troubleshooting

Machine Does Not Power On

• Check the power cable connection to both the machine and the power outlet.
• Verify the power switch is in the "ON" position.
• Inspect the fuse. If blown, replace it with a fuse of the same rating.

Injectors Not Firing During Test

• Ensure pulse signal cables are securely connected to both the machine and the injectors.
• Verify the correct injector voltage (12V, 70V, 120V) is selected on the control panel for the specific injector type.
• Check if the selected test mode is appropriate for the injector type and condition.

Leaks During Testing

• Confirm that injectors are properly seated and secured with the correct adapters.
• Inspect O-rings and seals for damage and replace if necessary.
• Ensure all connections are tightened appropriately.

Inconsistent Spray Pattern or Volume

• Perform ultrasonic cleaning to remove any blockages within the injectors.
• Ensure the test liquid is clean and free of contaminants.
• Verify the pressure setting is correct for the test being performed.
