Failure performance, cause analysis, sum up elimination
Boot no output, no voltage indication, or no start
1, over voltage or under voltage protection (adjustable internal output voltage adjustable potentiometer)
2, the fault phase and the lack of protection (three-phase arbitrary exchange two phases)
3, the main control circuit board is broken (change)
4, the output of the exchange is bad (change)
Output voltage is not normal
1, is the regulator (replacement homology regulator)
2, more than the regulator's own voltage range (the replacement of a wide range of regulators)
3, travel limit switch is bad (change)
4, phase circuit board has been bad (replacement)
5, servo motor burned (replacement)
Unregulated
1, more than the regulator's own voltage range (the replacement of a wide range of regulators)
2, travel limit switch is bad (change)
3, the circuit board has been bad (replacement)
4, servo motor burned (replacement)
Trip without reason
1, total gate capacity selection is small (change the appropriate capacity air switch)
2, the air switch is bad (change)
3, surge voltage transient is too high (replacement of non contact high precision voltage regulator)
Voltage regulator inside humming sound great
1, overload with load (reduced after the equipment)
2, inside the debris (removal of debris)
The internal regulator squeaking sounds great
1, voltage instability (normal)
2, the surface of the carbon brush with gray scale (remove dirt after the power outage calls)
Regulators can not automatically run
1, automatic toggle switch is not open (open)
2, circuit board failure (replacement)
Lifting or lowering the pressure of the panel according to the panel
(non power regulator without this feature)
1, servo motor burned (replacement)
2, travel limit switch is bad (change)
3, circuit board burned (replacement)
4, automatic and manual knob to open the manual (open to manual)
Tips: if the regulator failure, can not be ruled out, but also can not stop the power supply to the back-end equipment; please contact the Professional Company.
