I have two Multiplus II-2x120 wired in a parallel configuration in my class A coach. The coach Transfer Relay provides a warm up period when I use my generator. I am trying to implement a generator cool down cycle. I am using Guimods and my Cerbo GX for the generator control and it has been working great but it does not provide a cool down cycle when it turns off the generator.
I have worked out the necessary timer relays to get the necessary signals. I intend to use the General Flag to Ignore the AC Input to shed the load off of the generator during the cool down time period.
Question #1 - Can I program the General Flag on only one of the inverters, or must I program it on both inverters?
Question #2 - If I can program it on one inverter only, does it matter which inverter?
*) Use General Flag
*) Set Relay On
*) When Auxiliary input 1 is closed for 1 seconds
*) Use General Flag
*) Set Relay Off
*) When Auxiliary input 1 is open for 1 seconds
*) Use general flag to ignore AC input 1
