Another Hair Brained Idea
by on 04/13/13 09:00 PM
Hi Group, I would like to run this by you. I built 5 of these things six years ago. They now test KU, K10, IBM, KH, R10 and KR Series relays. Voltages available are 12v, 24v, 48v and 110v AC/DC Its 11” x 10” x 6” and weighs 7 Lbs. I still have one and the other four are still out there and working. The guys that have them are very satisfied with their performance. The auto feature continuously cycles the relay so numerous relays can be tested. Single relays can also be tested over any period of time. Tested relays drive LEDs. So, very little current passes across the contacts which are more likely to indicate a flakey contact. I would like to start building them again with some minor changes. Mainly drop the KR (round base) series because we don’t see many of these in our business. A couple of questions: Are there any other types of relay sockets that need to be added? The cost of production is a little heavy; material alone is around $150.00. Construction is quite labor intensive. With labor and material cost out the door could be around $700 to $800. Maybe less with some volume. Any comments or suggestions would be greatly appreciated. Regards, Jim

While not having used the model in the picture, I have used several home made and commercial models through the years. Where I've seen them come in handy is on intermittant problems on controllers with LOT's of relays. (Dover Composite, Old Montgomery, etc. ) Can be a real time saver. There are however several commercial units available. Here's one from ECI. http://www.eciamerica.com/Elevator-Diagonistic-tools.php

Is a "KH" relay like a Schindler "H" relay? You know, the ones they put on the mid-80s' GEM, GMG, etc? Tiny little wafer-thin pins, get bent easily.
Those relays are like $50 a piece. I'd hate to have to put in 10 new ones for maintenance and troubleshooting, if I could test 'em first. Could actually save money.
Yep Vic...And then you've got to be super careful when you put them back in the controller because bending a pin is real easy. They called them "Form C" relays down in my neck of the woods.

“Swappers, Testers and Aces”
For The Swappers “Hey we've all done it with exception of the “Ace Trouble Shooters” which I’ll cover later.
Had a boss (Owner as well) that took calls. We had a lot of Montgomery junk that had a zillion of those 4 pole ice cube relays. Come 11 PM, 20 butts on the floor, lobby full of pissed off Hotel Guests and a taste in my mouth that resembled that of a Vultures Crotch. Still in the machine room staring at a broken elevator with 2 used relays in the parts cabinet, condition unknown. Boy, this guy Knew how to make a profit.
Start swapping and for some reason things went from bad to worse. “Wonder Why?” In order to keep his cost down, The Bosses approach was to locate the problem relay with a bad contact or broken shunt and insert it in another socket that didn't use that pole. He’d been doing it for years. Hey! I just got in town.
Another swapping mine field would be “Armor” you know the ones with all those 3 pole relays that fit an odd ball socket only made by GE and over time an oil mist has accumulates inside the case so you can’t even see what’s inside much less determine the voltage. Start swapping, power on, and bingo the controller looks like the bridge of “The Star-ship Enterprise” while under attack by the Klingon battle fleet. “Wonder why?” there are three different voltages on those things starting at 24 Volts and ending up at 240 Volts and maybe even some in between only used in a distant Galaxy far,far away. That OHM never got to.
Last but not least are the relays with the tiny wire pins, we won’t even go there.
Now let’s talk about “The Ace Trouble Shooters” approach to relay problems. You know the ones (unless your one yourself) Yeah, the guys that always have a clean shirt only carry a meter, little tiny screwdriver and a laptop and that have no respect whatsoever for the guys with less than “Top Notch” trouble shooting skills and must resort to using a relay tester. You know these guys too, the guys that just want to fix the elevator, give the customer and his boss a fair shake and get home. Maybe even during the testing process another problem might show up that becomes an "Ass Bitter" down the road. On the other hand the "Aces" are lucky enough to have a Boss that will let him probe, measure, study diagrams(if available)and draw out complicated circuits on the machine room wall for an hour or three on a little full maintenance 2 stop hydro that bills out at ninety bucks a month.
Nothing Personal
Whichever you are, work safe………………

But on an intermittant call, and you've used the tester for speed, you finally have to sit down, and find it.
