Dear all, we would appreciate some assistance, ideas and solutions.
Problem:
After changing my batteries, the "Bulk + Mains on" LED lights (code 24 ) appeared fixed on my Quattro master (2 in parallel) and this alarm is permanent.
In the Quattro manual it means: Switch-over system protection initiated.
I can't get out of this state.
Increasing the AC input voltage to 210V and multiple resarts do not change anything.
The fault remains after having spent the Quattros in StandAlone and the same thing after inverting the master and the slave.
I also upgraded the Quattro version from 26.41.474 to 476, with no success, the transfer switch always stays on AC-In-1 to AC-out-1 and most importantly the Quattros don't see the batteries.
How to cancel this state and return to normal ?
Thanks for your help.
Best regards
