Hi Muzzer,

Yeah, the Chinglish is whats confusing me, im obviously no expert in electrics anyway but coupled with the Chinglish it just makes it even harder to understand...

This is all brilliant, thank you for the detaild info, I will print this off and go through it as there's a lot to take in but thank you so much!

One point on the Control Woring, you mentioned using AI3 for the +/-10v but I don't think I have that terminal, I think that's part of the PG expansion terminal that is bought separately, if that's the case would I be able to use AI1 or AI2 terminals or not...?

Cheers again

Phil
