Specific exclusion Fault Analysis
I. First, the external power supply and power switch box problem
Troubleshooting:
1. As shown Figure 2, please check if the power filter outlet loose? Is there AC220V power output from the flapper home?
Check and excluded.
2. Filter, is power switch itself good? I did plug the power cord plugged in correctly? Check and excluded.
II. Second, the fuse burned Troubleshooting:
1. As shown in Figure 2, a power switch with a 4A fuse or in Figure 4 the power board with 6A fuse if it fails to boot after being burned,
So burn this two fuses There are several possible:
⑴
shown in Figure 7, "471" varistors short-circuit breakdown, removal or replacement can be solved this problem.
⑵
power switching power supply circuit board DC5V short-circuit breakdown some components, such as "4007" diode, "4.7UF / 400V"
capacitor "274" integration, exclusion or replacement can be;
