SW4024 switching issue [RE-wrenches]

[Kirk Herander, VT Solar]

Kurt:

I did find a vague reference to the 40 sec. delay in the original piss-poorly
written 4.01
manual(page 25), implying that the delay exists. But I wonder. I don't ever
recall,
when moving the cursor to off on the front panel, having the generator wait 40
seconds to shut down after the transfer to inverter mode takes place. Transfer &
genny shutoff occur simulateously on every inverter I've installed w/ 4.01.
Conclusion: vaporware. Maybe it's in 4.1. - but I'm probably dreaming.
