High power compensating power voltage maintenance
| Fault phenomena | General analysis of the causes | Processing method |
| Electricity, after startup, voltmeter no instructions | 1, input cord didn't answer the prison without output voltage; 2, switch (C45) didn't open or insurance tube has bad; 3, voltmeter is bad. |
1, check input connection are reliable power; 2, check the switch (C45) is open or insurance replacement pipe; 3, replacement |
| After electrify, voltmeter instructions is not accurate | 1, voltmeter is bad; 2, control circuit board, tuning potentiometer aging or not tuned and lead to deviate 220V voltage. |
1, using a multimeter to measurement output voltage, if reading is 220V, criterion the voltmeter bad replace then; 2, using a multimeter to measurement output voltage, if not normal usable small screwdriver readjusted control PCB 1RP1 controllable potentiometer, its (near 220V voltage output. |
| Fault phenomena | General analysis of the causes | Processing method |
| After startup, output voltage is too high (over-voltage indicator), or too low (undervoltage indicator) | Power input voltage is not stable range 150V 240V or below is higher | According to the specific circumstances, if the power supply voltage is not normal and cause output voltage high + 10% must stop using one 220V voltage normal rear can, to boot. If it is too low, should cut sentiment reduce load power. |
| Carbon brush single-phase operation cause output voltage is too high or too low |
1, budge switch bad; 2, budge switch and control PCB loop connection between a disconnection phenomenon; 3, PCB bad. |
1, check whether the power switch budge, if damaged, replace reliable; |
| When the carbon brush operation sparks phenomenon | 1, carbon brush pressure is too small; 2, coil plane have insulation objects; 3 and carbon brush head off or part of a broken cause contact undesirable. |
1, readjust carbon brush pressure make its pressure suitable; 2, with sandpaper cleared eyewinker; coil plane 3, replacement carbon brush head |
| Regulators higher surface temperature |
1, use time into long; |
1, can be appropriately control use time; 2, check electrical equipment, it is best to use power whether overload no more than 70% of the rated capacity; 3, check the indoor temperature and ventilation is smoothly; 4, have fine sand processing interface. |
