Service

Committed to providing you with better support!
We make the following commitments to after-sales service:
1. Warranty period: During the warranty period, we will repair or replace any parts damaged due to quality issue, without any additional charges. If the parts are damaged beyond the warranty period, only the cost of the accessories will be charged. In the event that the equipment is damaged due to human factors by the buyer, we will undertake repairs or replace the accessories at cost price. Furthermore, during the quality assurance period, we are obligated to provide technical services and support for all equipment failures attributed to non-human factors, excluding scenarios such as war, disasters, and human-induced force majeure events.
2. Service commitment beyond warranty period: After the quality assurance period ends, we will also provide free voice and video services, remote debugging services, free software upgrade services, and commitment to bring product on-site maintenance services.

3. Response time and response method: During the warranty period, if the equipment malfunctions, we will arrive at the customer's repair site within 8 hours locally and within 24 hours for other provinces after receiving the user's repair request. If the equipment cannot be used normally after multiple repairs due to performance issues during the warranty period, we will replace it with a new device free of charge. After the warranty period, if the product malfunctions, we can send a technical support engineer for free on-site service. If parts need to be replaced, they will be supplied at the most favorable market prices. We have resident technical support engineers in many locations across the country to respond to related needs promptly.

4. Service working hours: For all products supplied, we adhere to 24/7 service, every day of the work.
5. Regular Follow-up: We conduct annual follow-ups on all supplied products, performing regular inspections and maintenance to extend the equipment's lifespan.

Q&A

Product category

Retrieval

？Q During the aging process, the software occasionally reports an error of 300 / 200 / 301 / 201

A

Cause analysis
1. The network signal communication may be unstable during the aging process;
Solution
1. Replace the shielded network cable, and update the software to the latest. The latest software can be connected repeatedly, and no error will be reported once it is interrupted. Only the background record will be made, and the error will be reported if the communication is not available for a long time;
？Q Click "start aging" on the software, and a black screen occasionally appears during the contactor startup process.

A

Cause analysis
1. Electromagnetic interference caused by contactor startup causes black screen of all-in-one machine;
Solution
1. Replace all network cables with shielded network cables, and add aluminum foil capacitors on the contactors;
？Q The oven cannot reach the reasonable set temperature

A

Cause analysis
1. It may be that the power of the heating wire is insufficient or has been blown;
2. It may be that the strong discharge setting is incorrect;
Solution
1. Measure the current flowing through the heating wire. The to aging current is about 13A. If the current is too small, ask the oven supplier to replace the heating wire;
2. Check the setting of forced exhaust. The reported parameter - 2 is to start the forced exhaust 2 ℃ in advance of reaching the specified temperature. At this time, the temperature rises slowly, and even never reaches the specified temperature.
？Q The whole board of multiple aging boards displays red error, and the current value in the data is 0

A

Cause analysis
1. It may be that the connecting wire behind the drive board is loose;
Solution
1. Check the connecting wires on the back. If it is a single connection, replace it with a multi connection. In addition, if multiple drive boards are powered off, it is likely that the wires connected to the power brick are loose or not in good contact;
？Q The over temperature condition as shown in the figure appears on several aging boards

A

Cause analysis
1. The setting value of product temperature protection value in parameter setting is too low;
2. The temperature sensor on the aging daughter board is abnormal;
3. Abnormal temperature control of temperature box;
Solution
1. Set the product temperature protection value in the parameter setting to the normal value range.
2. Check the temperature consistency of other temperature sensors on the aging daughter board and check the abnormality of the temperature sensor.
3. Check the causes of abnormal temperature control of the temperature box, such as whether the electronic sealing valve is opened, whether the solid-state relay is melted and the output end is in a long-term on state.
？Q 12V voltage abnormality occurs in several aging boards

A

Cause analysis
1. The power switch is not fully turned on;
2. 12V switching power supply output is abnormal;
3. The power connection line on the drive board is loose;
4. Abnormal driving board;
Solution
1. Check whether the power switches are all turned on, such as the knob switch at the front of the machine, the flat button and the air switch at the rear;
2. Use a multimeter to measure whether the output terminal voltage of the corresponding 12V switching power supply is abnormal;
3. Check and plug the power connection line on the drive board;
4. Replace or repair the drive plate.
？Q The number of plug-in times of the aging board is insufficient (only for the aging board with EEPROM and can record the number of plug-in times)

A

Cause analysis
1. The number of pluggings has exceeded the maximum number of pluggings set in the system settings;
Solution
1. Replace the aging daughter board or increase the maximum number of pluggings in the system settings.
