2. Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

2.1.1 Spesifikasi Koneksi Daya

Based on the nameplate, connect the test chamber to the correct power source, typically 220 V, 50 Hz (60 Hz available upon request), and ensure the voltage and frequency are correct. Please use a dedicated circuit to avoid sharing the circuit with other high-power equipment. Verify that all connections are secure and free of looseness.

2.1.2 Persyaratan Pembumian

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

2.1.3 Electrical Operation Contraindications

Before wiring, servicing, or maintaining the test chamber, you must disconnect the main power supply and confirm that there is no residual voltage before proceeding;

Jangan mengoperasikan sakelar daya ruang uji, layar sentuh, atau tombol instrumen dengan tangan basah untuk menghindari risiko sengatan listrik;

Jangan meletakkan benda asing apa pun (seperti perkakas atau kertas) di dalam kabinet kontrol listrik untuk mencegah debu atau benda asing menyebabkan korsleting atau merusak komponen;

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

2.2 Keselamatan Operasional

When the drip tray is being raised or lowered, do not touch the drip tray, the lifting motor, the steel cables, or any other parts to avoid danger;

During testing, entry into the test area is prohibited, and touching the turntable or samples is prohibited. If maintenance is required, testing must be stopped, and the power and water supply must be shut off before proceeding;

If the test chamber malfunctions, non-professionals are prohibited from disassembling or repairing it; contact LISUN Customer Service or operate the equipment under the guidance of a technician.

2.3 Keselamatan Lingkungan

The distance between the drip tray and the wall, as well as surrounding equipment (such as other test equipment and shelves), shall be at least 1500 mm to facilitate operation and maintenance;

The drip rack must be placed on a sturdy, level surface. Use a level to ensure it is level, making sure the bubble in the level is centered. If the unit is tilted, it may cause the drip tray to jam when raising or lowering it, result in uneven dripping, or even damage the equipment. Note: The legs of the drip rack are adjustable to ensure the unit is level.

3.2 Cable Connections

Gambar 4

3.3 Air Compressor Connection (if applicable)

Air line connections at the bottom of the control cabinet. If your company has an air compressor, you can connect this hose to the air compressor (supply pressure: 0.3–0.8 MPa). After testing is complete, you can use the air compressor to remove any residual water from the drip tray.

Gambar 5

Note: Not connecting the air compressor does not affect the equipment’s foundation drip test function.

3.4 Sambungan Pipa Air

3.4.1 Inlet Pipe Connection

Simply connect the filter’s inlet to a faucet. The IPX1 and IPX2 water resistance tests do not require a water pump; normal faucet water pressure is sufficient.

Gambar 6

Note 1: The water inlet faucet may remain open. Once the equipment is started, the program uses a solenoid valve to control whether water is fed into the drip tray. At the end of the day’s testing, simply close the water inlet faucet.

Note 2: We recommend using deionized water or purified water (a water purifier may be used); if tap water containing high levels of minerals and impurities is used, it may cause scale buildup, which can affect the test water flow rate and may require frequent filter replacement and needle cleaning.

3.4.2 Outlet Pipe Connection

Connect the control cabinet’s outlet pipe to the connection point above the drip tray.

5.1 Siap

5.1.1 Test Parameter Requirements

Note 1: How to tilt the turntable 15°.

Gambar 22

Note 2: Formula for converting water flow rate to rainfall: Water flow rate (L/min) = Rainfall (mm/min) × 0.001 × Rainfall area (m²) × 1000 (1 millimeter = 0.001 meter; 1 cubic meter = 1000 liters)

5.1.2 Menghubungkan Kabel Daya Sampel

If the sample requires testing under power, use the standard waterproof plug and socket to make the connection, and check that the connection is secure and free of looseness.

5.2 Uji Coba Saat Memulai

5.2.1 Selection of Levels and Parameters

On the main touchscreen interface, tap the IPX1 or IPX2 water resistance rating selection button, and the program will automatically apply the standard parameters; tap the “Test Parameters” button to confirm that all test parameters meet the standard requirements, and then tap “Back” once the settings are complete.

5.2.2 Adjusting the Drip Tray Position

Click the “Lower Drip Tray” button on the work interface; the drip tray will lower automatically until it hits the limit switch and stops. At this point, the distance between the drip tray and the top of the sample is 200 mm (as required by the standard), and no manual adjustment is necessary.

5.2.3 Water Flow Regulation

Make sure the tap at the water inlet is turned on, then click “Start Test” to open the inlet solenoid valve. Tap water will slowly flow into the water circuit until water begins to drip from the needle on the drip tray;

Observe the standard flow rate display area on the touchscreen interface. Assuming a standard drip tray size of 800 × 800 mm, the standard water flow rate for IPX1 should be 0.64 L to 0.96 L/min, and the standard water flow rate for IPX2 should be 1.92 L to 2.24 L/min;

Turn the black knob on the flow meter in the control cabinet (turn counterclockwise to increase flow, clockwise to decrease flow). Observe the top surface of the float inside the flow meter; the water flow should remain stable within the standard range. Once adjustment is complete, keep the knob in that position.
