Welding joint problem handling: no trigger signal

表现：

  扣动扳机按钮时，检测页【激光器扳机信号】显示为灰色

Performance:

When the trigger button is pulled, the detection page [Laser Trigger Signal] is displayed in gray.

原因分析：

  扣动扳机时，信号接口一的7/8脚应导通状态，当出现断路或主板内部问题，则显示为灰色，结构如下图

Cause analysis:

When the trigger is pulled, the 7/8 pin of signal interface 1 should be in a conducting state, and when there is an open circuit or an internal problem of the motherboard, it will be displayed in gray. The structure is shown in the following figure.

故障处理：

①同时测试安全地锁信号是否正常，个别情况为航空插口松动，会导致两个信号都没有，航插位于焊接枪的线往后80cm处

②直接短接信号接口一的7/8脚，如导通则主板没问题，继续下一步的检查

③拆开按钮，测量按钮到端子的通断，个别情况为线断了

④当以上都没有问题时，多数为按钮本身的问题，如接触不良等，需更换按钮

Troubleshooting:

① At the same time, test whether the safety lock signal is normal. In some cases, the aviation socket is loose, which will lead to no two signals. The aviation socket is located 80cm behind the welding gun line.

② Directly short the 7/8 pin of signal interface 1. If it is connected, the motherboard will be fine, and continue the next inspection.

③ Disassemble the button and measure the on-off from the button to the terminal. In some cases, the wire is broken.

④ When there are no problems above, most of them are the problems of the button itself, such as poor contact, and the button needs to be replaced.
