Causes of failure of Altiverb 58 series
That is more than a year ago had a chat with one power on output (common failure) altiverb 58 series. We will focus on the large hotel complex in which three buildings. Each 4 Elevator shafts. Elevator usual brand "lift 1000", everything else in Italy. On the phone spoke with this client from Moscow for a long time. Every time clarifying new surprises.
After the first communication, I did not understand the reasons of the output of the inverter in such a mess, I mean, there, there for no apparent reason. The first advice was to Check all the grounding altiverb. Reliability crimp lugs leading to the ground.
After a week break energetics of called and said that in one of the buildings on those lifts where most burned Altiware was a bad ground but not directly at altiware, but directly in the closet on the ground bus. In one mine crimp was bad and the other side had come loose connection. Eliminating data errors maintenance and installation, we decided to continue monitoring the stability of all Elevator shafts.
after more than six months and again sounded "the long-awaited call" on the Central body flew Altivar 58. Still others worked in normal mode. Apparently lifts the Central buildings of the hotel are slightly saturated and power reserve of Altivar 58 22kW inverter and the Motor 15 kW lacked. Because of this protection trips current at chastotnik, an error appeared SCF. Again walked in the phone mode on the basic settings altiverb and all was normal. Then I was advised to put in trial mode on the main shaft of Altivar 71.
it took probably more than a half year, and I called again with words of gratitude and said that the mine where stood Altivar 71 never gave a crash per year, and the rest of the mine periodically went into error, but not burn burned no Altivar. Guide hotel complex has decided to change all Altivar 58 on Altivar 71 and as a result already for quite a long time to me with questions why do I have your altar burned No one with this object does not ring. Hence the conclusion.
the Correct installation and correct configured equipment is the key to its long and trouble-free operation cycle.
