Description
Edley transducer maintenance
Model: AS-107
Fault: boot without display
Fault analysis: This is the most common fault of many inverter, usually caused by load switching power supply short circuit caused by the output inverter aideli by using UC3842 to adjust the switching power supply at the same time, the intelligent module also with the current detection, when there is no display control terminal voltage, DC12V, 24V fan is not running phenomenon we should first consider whether the switching power supply is damaged. The DC bus voltage of the inverter is normal, and the switching power supply is not up. Switching power supply IC-UC3842 power supply voltage 15V not to. Preliminary judgment for power start-up circuit fault. Measurement of switching power supply starting resistance 200K infinite.
Fault repair: replace the switch power supply to start all the normal electrical resistance.
