UAX Group Selector
Hi all, I have acquired a UAX Group Selector which I am trying to get working. I have connected 48DC +ve to U11 and -ve to U12. Earth is in TJ11, tele into TJ3&4. These details were from searching the net, you tube etc.
When I pick up the phone relays A & B operate and A pulses the dialled number. If I hold in relay CD the selector steps with the dialled number and when I release CD it returns home. What am I missing to get the selector to step automatically? Thanks in advance. |

Re: UAX Group Selector
What is the number of the diagram which is usually on a small paper label underneath the selector if you turn it upside - should be AT/ATW.... I've got virtually all the UAX diagrams for UAX5, UAX12/13 and 14.

I'll PM them all to you as they run to quite a few. Luckily I got my new printer/scanner that will do up to A3 going today. Covers 'foolscap' which earlier GPO diagrams/diagram nots were but the old 'imperial' equivalent is larger than A3 regards Ian J CNet 0352 2345 MR ETD 053-6278 |
