The incinerator is obstructed and cannot be broken down. It is necessary to inquire about the period of each incinerator. Here is a brief description. One. There are many obstacles and breaking skills in mastering device: first of all, with 530se, for example, from the layout and circuit description of mastering device, all the mastering devices of 530se liyalu are very simple, so as to produce small obstacles and easy shooting. Common hindrances prevent war.
1. How to deal with the fire? For the first time, open the master's shell, and investigate whether the investigator's master's equipment and circuit board are burnt. The scorched equipment is very common. The varistor is burnt out instead. Another plane resistance wire is burnt. Flat wire burns occur frequently. Occasionally, only wounds happen again. The master can revive the normal. Once the wounds have been destroyed, the power supply is short circuited and the replaced power tube can recover to the normal. Flat wire burned out, power tube damaged about 60% 530se master after sale.
2 if you are an internal component of the master and there is no trace of burning on the circuit board, you should check whether the master is available. Provide 530se to master the power of the motor in 3 feet (n) and 5 feet {l} for continuous 6 feet and 6 feet. When the electric motor of the motor, the 50 V switching voltage is 7 feet, and the flat wire pair masters the circuit. So, for the first time, the 250V document of the multimeter exchange measures whether there is 220V at 3 feet (n), 5 feet {l}. If there is no voltage, it indicates that there is a problem with the external power supply, and then measures whether there is 220V at 3 feet (n), 6 feet {l}. If there is no voltage, it indicates that there is a problem with the touch points inside. Some of the common obstacles are poor touch points, probably the touch points are open. The former is only lightly polished with fine leather polish, which can be plastic to contact reed and make contact to. 3. 6 feet high, if it doesn't burn, you should check the power supply to master the circuit power supply. Use the multimeter's DC 50 V DC voltage output to measure whether the bridge is facing the north and south poles. The bridge is often damaged, which can be replaced to restore the normal.
4. Zhang Ruo has doubts about the liquid level control circuit and combustion transformer. Because of the low rate of hindrance, is not to say.
Two. There are many obstacles and breaking skills in mastering the device, and the road condition of RIA repaired:
1. Small power supply voltage regulator;
2. 530se master base;
3. Internal wiring, RIA method G20, for after-sales reference;
4. MF 47multimeter;
5. 30W internal heating soldering iron;
6. It is used to replace the components that are still damaged in frequency, such as power transistor, transistor, diode, zener diode, qiaodui, flat steel wire resistor and varistor;
7. Common object set;
