IP Waterproof Test Equipments JL-34

Q1: After starting, I can hear the sound of the water pump, but no water comes out
A1: Please make sure that the voltage and frequency of the power supply connected to the equipment are consistent with those marked on the nameplate. If not, it will affect the water pump and even damage the equipment.
Air in the water pump will also affect the water pumping effect. Fill the water tank with water and start the water pump after the water enters the water pump.

Q2: The touch screen prompts “Water tank overfilled” as follows

JL-34 Water tank is overfilled

A2: The position of ① float ball of the water tank may be changed during the transportation or handling of the equipment. The float ball is too high, causing the water level upper limit sensor ② to float up and alarm. Please rotate the rod of the float ball ①, or slightly bend it to lower the final position of the float ball. When the water level of the water tank is at the highest point refer to the float ball, and do not float the sensor ②, then there will be no error.

Q3: Click “Test Start”, but the equipment cannot start the test, and the following errors on the touch screen:

JL-34 Oscillating tube is not at 0

JL-34 Test time is not reset

A3: Please click “return”, and click “Tube reset” to rotate the osillating tube to 0 degree position, and click “Time reset” to clear the time of the last test, and then click “Test start” again.

Q4: During testing, the sample power cord is tangled?
A4: The turntable we designed will only rotate in one direction when the sample does not need power supply. When the sample needs power supply (click “Sample Power Supply” on the touch screen), the turntable will automatically change the direction of rotation every minute without causing the power cord to get tangled.

Q5: The needle get blocked
A5: For the first use, please clean the oscillating tube and the inside of the water hose before installing the needle. Use clean water as much as possible. If the filter element changes color after long-term use, please replace the filter element in time to ensure that no debris enters the oscillating tube. If the needle is found to be blocked, use the tool provided by LISUN to clear the needle and then reinstall the needle.

Q6: How to use counterweight?
A6: In order to ensure the stability of swing tube rotation, only large-size swing tubes (radius 1.4m and above) will be equipped with counterweights. Small size swing tube does not need to use counterweight. The counterweight is shown in the following figure:

Q7: Turntable size and height
A7: In order to match the swing tubes of different sizes, we have a variety of turntable sizes, and the height can also be adjusted. Select the turntable of the corresponding size and adjust it to the appropriate height.

Q8: How to confirm test results?
A8: If the sample short-circuits and shuts down during the test, it is definitely not in compliance with the standard. If the sample can still start and run normally, you need to take out the sample, wipe off the moisture on the surface, and then open the sample to check whether there is water inside. If there is water, it is also not in compliance with the standard.
For specific details, different industries have different rules, and you can refer to the corresponding industry standards.
