NS2

Good morning
We have just installed our new NS2.
When it was connected the green light was 3on/3off and the red light was 6on/3off.
When I ran the engine the red light went away, the green showed 3on/3off, and the orange light was on [ we do not have it wired for battery Combiner option].
Now with engine off we have the orange on and the green 3on/3off. Is this normal?
Your prompt reply to this would be appreciated as we have to leave here and will not have internet.
Thanks SA
PS the voltage with ending on was correct for absorption as I set it.
