PP836 System Error- A_I # 3.0
For a High Power Rectifier Control I have a AC800M together with a PP836 communicating via Ethernet. The system was running without any problems for more than a year.
Now the custemer reports the following alarm on the Panel:
System Error- A_I # 3.0
(see also picture)
I never saw this error message before and I can not find any document which describes this error.
I advised the custumer to restart the PP836 by disconnecting the power and conect it agin.
After the restart the folowing message appeard:
"The application was not loaded correctly the last time. Do you want to remove the application?"
So they entered "No" and they ended up on the same page as before with the System Error- A_I # 3.0
Has anybody an advise how to fix this problem and what could have caused this problem?
