After-sales

Committed to providing you with better support!
We make the following commitments to after-sales service:
1. Warranty period: During the warranty period, the supplier will repair and replace the parts damaged due to quality reasons for free. If the parts are damaged outside the warranty period, only the cost will be charged for the accessories, and the equipment caused by human factors of the buyer Damaged, the supplier repairs or brings the accessories at cost price. During the quality assurance period, we are obliged to provide technical services and support for all equipment failures caused by non-human factors (except war, disaster, and human force majeure).
2. Service commitment outside the warranty period: After the quality guarantee period, we will also provide free voice and video services, remote debugging services, free software upgrade services, and promise to bring product on-site maintenance services.
3. Response time and response method: During the warranty period, if the equipment fails, we need to go to the site for support after receiving the repair report from the user. Arrive at the customer's maintenance site within 8 hours locally, and arrive at the customer's maintenance site within 24 hours from other provinces and cities and overhaul in place. During the warranty period, if the equipment cannot be used normally due to repeated inspections of equipment performance failures, we will replace the new equipment free of charge. After the warranty period is exceeded, if the product fails, we can send a technical support engineer to provide free on-site service. If you need to replace the accessories, the accessories will be provided at the best price in the market. We have resident technical support engineers in many places in China, who can respond to the relevant needs of the tenderer in a timely manner.
4. Service working hours: For all products supplied, we insist on 24 working hours a day, 7 days a week, 24 hours a day.
5. Regular return visits: We insist on regular return visits every year for all the products we supply, patrol inspection and maintenance to prolong the life of the equipment.

Q&A

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.
