dx9100 problem

[wtfg]

I lost all 6 Ai on the 9100, it shows 250 on all AI. The AOs all show up
I have 3 xt and those Ai show up, Is the DX bad or does anyone know what could be the problem

[chrisc]

Is this a new install? If not it sounds as though the AI's on the DX are bad, can you read resistance thru the sensors with a meter?

[wtfg]

No its not a new install, and yes the sensors show the right resistance.

Check your jumpers on the back of the dx. Ai's can be set up passive or active.

In the last ten years I have seen this problem twice.
One was a DX9100 and the other was an older model LCT.
The capacitors on the AI's had dryed out causing all AI's to go unreliable.
How old is this installation.
