We bought a use PV as a backup. Our PV's in use have Fw3.30 and the spare has 3.13. Thought we could upgrade the FW to 3.30 to have better compatibility.
While using the Upgrade utility we realized that it only version 4.xx was available. We gave it a try thinking that we could standardize on 4.xxn
The FW upgrade did not work - now our spare has a corrupt system. It was self checking then showing an error 74.
On subsequent trials it does no longer self check - just shows:
Verification/ Autotest
40
Error! Fehler! etc.
What options do I have to correct this? I think the PB 3.20 and 3.40 have the older FW. However I need to find out how to get into the configuration menu again.
We downloaded via RS232 - what options do we have using a CF card?
