I have a an issue with a micrologix 1400 control system with a 1762 if4 analog card.
I have 3 devices connected to the analog card one 0 to 10 vdc. and 2, 4-20ma transducers
For some reason the 0-10 volt signal which is a strain gauge amplifier is showing saturation on my HMI and shuts down the system but not the other two signals are fine.
If I power down and back up this clears the fault and all is fine for a day or so then I get the same fault the analog card shows 32768 as the counts which would be saturation.
Is there a reason the micrologix would retain the saturated condition?
Thanks
Jay
