KONE KONE elevator inverter maintenance
Hong Jia Wei professional maintenance KONE km converter, KDM drive, KM997159, KDL16SV3F18, V3F25, V3F16L, KDL16L, KDL16R, V3F18, KDL32 series inverter fault, fault code 0130, 5000 - 96, 76, 213, 50, 51, 21, 53, 54, 61, 72, 73, 74, 75, and 0130-51000131, 0026, 0025, 0108, 0036, no display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display without damage, error etc.;
Common faults of Tongli transducer
KM997159 inverter directly drag load elevator traction motor, the actual current is big, therefore, as the elevator control equipment, the failure rate is relatively high.
Common failures are as follows:
1, the elevator running serious jitter.
2, KM997159 inverter internal short-circuit fault, leading to power supply trip.
3, the elevator in the maintenance state can only operate in one direction, if you want to move in another direction, move together immediately stop.
4, the elevator suddenly crashes phenomenon, if the power to send electric and can operate normally, and the crash phenomenon will occur but running after a while.
5, whether in the repair state or in the normal state, the elevator can not operate normally.
It should be noted that when the panel in the KM indicator light, does not mean that KM997159 is normal. Many times KM indicator light, but the last reason to find out the problem is caused by KM997159 inverter failure.
Jia Hong Wei maintenance process
The first step: ask the user fault KONE km converter.
The second step: according to the user‘s fault description, analysis of the causes of such failures.
The third step: open the KONE km frequency converter is maintenance, confirm the device is damaged, the feasibility analysis of maintenance recovery.
The fourth step: according to the working position of the damaged device, read and analyze the circuit principle, find out the reason of the damaged device.
The fifth step: contact with customers, reported maintenance prices, seek user maintenance advice.
The sixth step: looking for the relevant device for distribution.
The seventh step: determine the KONE km inverter fault and reasons are excluded, electricity experiment.
The eighth step: in the KONE km inverter under normal working conditions, enter with normal load test after the customer use
