does everyone who gets ranked as technician lose their brains?

[gnuuser]

while instructing an apprentice at running conduit for a machine change today some contractors were installing a varimot drive motor with the assistance of the manufacturers tech.
they frogged around with the motor for nearly 3 hours trying to get it to run.
including changing out the motor and inverter head!

i remembered the varimot drives will show a fault and shut down the motor to prevent the motor from single phasing should it lose a leg.
when i mentioned this bit of info i had my guys meter the legs and what do you know they found leg one dead (new fuse but faulty)

i mean really this is a rookie mistake to not check the fuses and supply legs to a motor
what kinda crap do they teach these techs?

Perhaps these manufacturing tech didn't have enough field experience, possibly so used to their in house own proved test jigs?

But yeah they should have check if all phases are in.

Not a lot if that is anything to go by!!
Which just shows the importance of testing and the all important ability of fault finding....

they sound like idiots.

i know on danfoss inverters etc you need to put a couple links in to get them to run.

its all in black and white in a book that comes with every inverter.

why they techs didn't check for V first no one will ever know

You have had an interaction with a certified idiot so does that make all Technicians the same? ... The world is full of numpties with titles well above their station for whatever reason but you shouldn't paint everyone with the same brush just because you meet one or two... he's probably a paper pusher lacking practical experience and yes! probably getting paid more than his worth but just ask him how a person holding a technician level of recognision does not do something so basic as testing and checking all voltage is present - a fundamental test, now yes complacency may play a part but when the drive didn't work it would be the first thing to check IMHO ... so ask him and revel in humour at his attempt to save face.

Makes you wonder how many days or weeks training the manufacturers techs get before they are let loose

 

[andyelectric]

Always a chuckle if someone doesn't check fuses as a starter for ten. I've even seen experienced guys do it when a fault looks like a common one thats nothing to do with supplies but turns out otherwise.

So you’ve never overlooked anything basic then? If you say you haven’t I’ll call you a liar to your face.

only one time when i was a rookie and i still remember the painful jolt from a capacitor bank quite well!
i must admit it did wonders to improve my ability to pay attention to details and procedures

i cant label all techs like those guys many ive met were top notch
but it made me wonder why they missed that ( i think these guys were in a bit of a hurry to finish up and it kind of bit them in the rear)
