The time for the development and use of the detection light curtain is not long, so how to guarantee the detection light curtain? First of all, we warmly remind you that under the guidance of the manual, the user correctly conducts the wiring, installation and maintenance of the safety grating, and this product is guaranteed for 2-3 years free of charge, with lifelong maintenance. Of course, it does not mean that when the product has a problem, we will come to us. Under the influence of non artificial factors, just imagine that the detection light curtain will be sent to you, and you will throw it around and break it. In this way, we must not be able to repair it. Here are some specific examples of what is not covered by the warranty.

The following conditions are not covered by the warranty:

1. Dismantle and test the light curtain circuit board and all parts by yourself;

2. Lightning strike or strong current entering the detection light curtain, burning the circuit;

3. Detect that the power supply voltage of the light curtain exceeds the specified voltage, and the circuit board is burnt;

4. The cable head at the terminal is not tightly sealed, causing water or steam to enter the electrical box;

5. The model is not selected correctly, which exceeds the scope of use of the detection light curtain. For example, the ordinary detection light curtain has no waterproof and dust-proof function; If our detection grating is applied in a dusty and oily working environment, it may easily break down. Of course, for the light curtains such as spraying light curtains and vehicle separators, we will consider the operating environment ourselves.

6. Check whether the light curtain wire or a part of the whole machine is bruised or damaged.

As a manufacturer of testing light curtains, xaori's testing light curtains have two and three years of after-sale quality. The ones with controllers have three years of warranty, and those without controllers have two years of warranty. Specific remarks will be made in the purchase contract with you. The black paper, white words and seals have legal effects. We consumers need not worry too much about this.
