Funny stuff everyone. But not the part about operators procedurally resetting drive faults. Drive faults can result from a complex set of circumstances and should always be diagnosed by someone with relevant experience ie. an industrial electrician or engineer really. Take a look at any drive manufacturer's manual and see what YOU think.

A commonly occurring nuisance fault with DCS500s at our hill is "No Field Ack". So what is that supposed to mean? It means you go to the manual and then combine that with all the circumstantial evidence to make a decision. Before deciding to push reset.

Anyway — unfortunately — most lifts have the drive reset tied to the green button which in combination resets the entire safety system. Not exactly desirable when there's anxious fingers around. It's most advisable to have the lift engineer/ industrial electrician place a seperate reset button beside the drive interface keypad so that they read it and record it as a matter of course.

Hey isn't "Code Grey" really a type of reflected binary numeral code? Oh no sorry that's "Gray Code" http://en.wikipedia.org/w/index.php?title=...amp;redirect=no. Nerd humor, but I digress.

Cheers gang.
