I recently got a 411 duplex, 4 stop, 350fpm, 4500lbs. And annual test have to be done. first of all never worked for the big "O", so know 0 about them. Borrowed the tool (check), got prints (check), got 2nd guy (check). Two problems,1)Testing of Normal and terminal stopping devices. Sure I can put my hand on the final, but can't run car there. No mechanical normals. Got to turned some stuff off with the tool but I don't know what (can't do buffer then). 2)Need a written check out procedure and demonstrate that all E/E/PS electrical devices work as intended. Even if I knew this I don't think I could trouble shoot my a_s out of one of these just looking at LED's without a tool. Talked to the local O office sure they'll sell us one gave a ball park figure, said but those are hard to get.???? So get us the part# and a hard $ we'll order it. That was last year, now you know why I borrowed a tool. Got 4) Gen2 globals also, I'll get traing on these, but we can't let you in the hatch, this is going to be fun. Sorry about the rant but any help would be a great help. Inspector coming in a month and those are the only ones that have to be done yet.
