    It means it did not complete transition from wye to delta during startup. Check your auxiliary switches in the starter.
    Your poor planning does not constitute an emergency on my part!!!!

    Well you would think so but the more I read some of the posts on here and see the questions people are asking it makes me think "what the #?!& are you thinking" .Does cool tech understand the idea behind wye delta or even know what wye delta is .Also you have to think about the customer here ,they are paying supposedly for a trained competent sevice tech and what are they getting for there money----- I'll reserve judgement on that.
    If you dont know what you doing then maybe you should have someone who does go with you that you can learn from before some one gets hurt or worse .To many people are getting hurt and killed because of lack of training and making mistakes . Cool tech dont become another statistic .

    This is a major problem through out our industry in all areas of it, from residential, refrigeration, commercial and industrial. This includes manufacturers as well as independents to joe blow working out of the station wagon.

    30 years ago everyone knew all the commercial players and which ones sucked. I'd venture to say it was less than 10% of the contractors that did crappy work. You knew everyone in the supply housses and who they worked for. The technicians actualy took pride in their work, that's gone out the window.

    I've watched it go downhill over the past 20 years. The introduction of the internet and cell phones has made the techs mentaly lazy. Very few spend more than their time on the clock learning. The majority of the owners/branch managers have no morals. They will bill out every hour and or more the tech was there even if it took them 100 hours to figure out a 5 ton condensing unit had a locked up condensor fan motor.

    Our industry is in an extremely sorry state. With the advanced controls, complicated systems, poor engineering and lack of information, I'ts all downhill from here. I'm glad I'll be out of it in 10 yrs or less if I can swing it. JMHO

    All I can say is we all started somewheres, not everyone was given factory training on every piece of equipment, at least hes trying and posting here trying to learn, I would take that anyday over someone who just hits the reset and walks away.

    Yes I do work for Trane and I have had SOME factory training but the point is ,cooltech had to reset the chiller as trasition failure is a manual reset diagnstic. He obviously is not farmiliar with wye delta starters . What would have happened if the starter had blown up at restart.
    Also you say its better than hitting reset and walking away . Think about it thats exactly what he did because of his lack of experience. yes hes trying to learn but at who"s expense . Not just the customers ,playing with wye delta is not for the inexperienced it is dangerous S#%& and when it goes wrong things go bang in a big way ?????????????

    The problem is guys out here will get killed "tinkering" with a 500 amp starter panel. Lets say someone leaves the starter door open and we reset it with not so good results. Anyone reading this just know the started panel can exploded and kill you. Does not happen often but it can. I'm Done ranting.
