2. 안전상의 주의

2.1 전기 안전

2.1.1 Power Connection Specifications

Based on the nameplate, connect the equipment to the correct power source, typically 380V 50Hz (60Hz available upon request), and ensure the voltage and frequency are correct. Wire the equipment separately to avoid sharing a circuit with other high-power devices. Verify that all connections are secure and free of looseness.

2.1.2 접지 요구 사항

The equipment must be reliably grounded, with a grounding resistance of ≤4 Ω. Do not use gas lines, non-metallic water pipes, or neutral wires as substitutes for the grounding wire. After grounding is complete, use a Grounding Resistance Tester to measure the grounding resistance. Power may only be applied after confirming that it meets the requirements, to prevent electric shock, equipment malfunctions, or measurement errors caused by poor grounding.

2.1.3 Electrical Operation Precautions

Before wiring, inspecting, or maintaining equipment, the main power supply must be disconnected, and operations should not begin until it has been confirmed that there is no residual voltage;

Do not place any foreign objects (such as tools or paper) inside the electrical control cabinet to prevent short circuits or component damage caused by dust or foreign objects;

Do not plug in or unplug power cords or signal cables while the equipment is running to prevent short circuits that could damage the controller or electrical components.

2.2 작동 안전

Before testing, securely fasten the sample to the center of the turntable to prevent the impact of the water spray from dislodging or displacing the sample; when conducting powered tests on the sample, ensure that the sample’s wiring is secure and that there is no risk of short circuits or electrical leakage;

The IPX6 test involves high water flow and strong water pressure. Before testing, ensure the water tank is full and that the spray gun is secured to the mount; do not conduct the test by holding the spray gun in your hand;

Do not place any objects within the equipment’s operating area. Do not enter the spray zone while the equipment is in operation to avoid being struck by a strong jet of water;

In the event of a malfunction, non-professionals are prohibited from disassembling or repairing the equipment; please contact us or follow the instructions of a technician;

If the touchscreen displays an alarm, immediately stop the test and troubleshoot the problem. Do not force the device to restart (to prevent further damage).

2.3 환경 안전

The distance between the equipment and walls, as well as surrounding structures (such as other test equipment and shelving), must be at least 1500 mm to facilitate operation and maintenance;

The water tank, nozzle bracket, and turntable must be placed on a solid, level surface. Use a level to ensure they are level, making sure the bubble in the level is centered. Note: The equipment’s feet are adjustable to achieve a level position.

5. 시험 전 준비 사항

5.1 샘플 설치

5.1.1 Preliminary Inspection of Samples

Inspect the sample to ensure it is in good condition and free of damage or deformation; confirm the test requirements for the sample (whether power-on testing is required and the waterproof rating). If power-on testing is required, refer to Section 3.1.2 to connect the sample’s power cord to an appropriate power source.

5.1.2 Sample Mounting and Positioning

Place the sample exactly in the center of the turntable and secure it firmly with a tie-down strap to prevent it from shifting or falling off while the turntable is rotating;

For electrical testing, follow the instructions in Section 3.3 to connect the sample using a waterproof plug, socket, and power cord. Check that the connections are secure, with no looseness or short circuits, and verify that all connections are properly waterproofed.

5.2 Pre-commissioning of Equipment

5.2.1 Equipment Functionality Check

If the equipment has not been used for an extended period, or if you need to verify in advance that all its functions are still operating normally, refer to Section 4.1.3 to check and confirm that the equipment’s pump, solenoid valve, turntable, sample power supply, and other functions are working properly.

5.2.2 Water Flow Pre-regulation

Still referring to Section 4.1.3, turn on the water pump and the IPX5/IPX6 solenoid valves. Adjust the IPX5/IPX6 flowmeter knobs so that the IPX5 water flow rate is 12.5 ± 0.625 L/min and the IPX6 water flow rate is 100 ± 5 L/min.

Once commissioning is complete, you can turn off the pump and solenoid valve.

6. 물 분무 시험

6.1 Start-up Test

On the touchscreen program interface, select the IPX5 or IPX6 waterproof rating you wish to test. If the sample is powered on, click “Sample Power.” Then click “Clear and Reset.”

Open the valve at the IPX5/IPX6 nozzle, then click “Start Test” to begin the water spray test. Please hold the nozzle and its bracket with one hand to ensure the water jet is aimed at the test area of the sample.

6.2 Real-Time Monitoring of Tests

6.2.1 Water Flow Rate

If the flow rate fluctuates during testing, you can fine-tune the flowmeter knob to keep the water flow rate stable at the standard flow rate.

6.2.2 Rotating Stage and Sample

The turntable rotates at a constant speed as set, with the sample holder unobstructed by water, ensuring that the sample is sprayed from all directions. If any abnormalities are detected, the test may be stopped, adjusted, and then restarted.

6.2.3 Electrical Conditions of the Sample

Power to the sample is automatically turned on and off according to the set schedule. If an abnormality occurs during the test—such as a short circuit—the test can be stopped immediately; after inspecting the sample, the test can be resumed.

7. 테스트 후 절차

7.1 Immediate Actions Upon Test Completion

7.1.1 Remove the sample

Press the “Stop Test” button, or wait for the test to end automatically; the turntable will stop rotating, and power will be cut off to the sample (for samples undergoing powered testing). Remove the sample from the turntable.

7.1.2 터치스크린

Check whether the test time display on the work interface is functioning properly, then click “Clear and Reset” to prepare for the next test.

8. 장비의 일상 유지보수 및 관리

8.1 일일 청소

Wipe water spots and dust from the surface of the equipment, paying special attention to the turntable and test area to prevent water spots from leaving behind limescale;

Wipe the touchscreen and control panel with a dry cloth to prevent water and dust from entering the internal circuitry.

8.2 정기점검

Connections: Check all connections on the swing pipe, water lines, and electrical circuits to ensure there are no leaks or loose fittings.

Thoroughly clean the water tank at least once a week: Drain any standing water, then wipe it dry with a clean cloth. After cleaning, check the inner walls of the tank for rust or scale buildup. If there is minor rust, gently wipe it with a rust remover, then rinse thoroughly with clean water.

8.3 Maintenance of Idle Equipment

8.3.1 Short-term Idle Period (Within 1 Month)

Drain all standing water from the tank and water lines to prevent scale buildup in the nozzles and pipes;

Cover the entire piece of equipment with a dust-proof cover to prevent dust from entering;

Keep the equipment in a dry, well-ventilated area.

8.3.2 Long-term inactivity (more than 1 month)

Complete all maintenance procedures for short-term non-use; disconnect all electrical and water connections from the equipment; remove the water hoses, let them air dry, and store them properly;

Apply a layer of rust-preventative oil to the inner walls of the water tank and the surfaces of metal parts to prevent rust; store the equipment in a cool, dry place away from direct sunlight;

Apply a small amount of industrial lubricant to moving parts, such as the turntable bearings, to prevent rust and jamming;

The equipment should be powered on once a month. Enter the manual screen to test all functions, then shut it down after 5 to 10 minutes of operation to prevent circuit deterioration.
