Sorry, but I have to vent (again). I spent the better part of a whole day trying to figure out why my Draper Silhouette V screen would only roll up and not roll down.
I ordered the 'VIC-115' option, which is simply a DPDT switch which is activated by 115V AC. When AC is present on the sense line, the screen rolls down, when there's no AC, the screen rolls up. Simple.
Well, after a few hours of scratching my head, I looked closely at the text on the relay and discovered that the switch is activated by 240V AC! Draper installed the wrong d#!% switch! Ok, after a quick trip to Rat Shack for a step-up transformer, I was in business, sort of. The relay clicked nicely when 240V was applied, rather than the buzz I heard before. Still, the screen wasn't going down.
It was only after I pulled up the datasheet for the relay on-line that I discovered that Draper's hook-up schematic is wrong! Bad hook-ups with high voltage AC are NOT a good idea! Fortunately, following their directions as drawn results in innocuous mis-operation.
Now, after several hours of debugging I've got a great screen that does what it should. Tomorrow I'm calling Draper to ask for the proper 115V relay (and get them to fix their schematic!)
