[GreenKeys] Model 15 remedial question Inbox

[Tom Hunter]

Jason,

You need to measure the current flowing through your model 15, even with a
multimeter in series with your loop.
It should be 60 Milliamps. I have voltages from 80 to 180 in my various
loops, but in all cases the current is set to 60 mils by variable
resistors. I have so many places to measure loops, I buy 100 milliamp panel
meters three at a time.

By the way, 120 is the most common voltage.

But the current MUST be 60 mils for a model 15!

If you have your loop connected to the selector magnet, it should be pulled
in already.If you can still push the armature in, then there is something
very wrong with you loop supply. Harold is correct - everything in the loop
is in series. If you want two machines to talk to each other, both
keyboards and both selectors are all in series across the loop supply.

I have machines in three different locations here and everything is in
series.
