My next step will be to contact Pace. I guess I'll have to send the handpiece and faulty tips back, which will be a pain, but we'll see.

Hello, did PACE help you? How did this story end?
Apologies, I've had a busy few months and have barely had time to even browse the forum. Didn't see this post till now.
So, quick recap, I made an order of an ADS200 and a few tips, and had two tips giving me the CHP error. I had my suspicions that it was a case of them not seating properly in the handle, as the other two tips did seem to seat further in. Given they're all different geometries, I didn't take that as conclusive.
I contacted Pace and sent photos of the tips, and they were able to identify them as being from an early batch. Apparently there's long since been changes to the production process and I should have gotten ones more recently produced. No indication of what was wrong, but it sounded like the black alignment collar might have been the culprit. Possibly it was preventing the tips from seating properly.
Support from Pace was first class. They sent over replacement tips for the two faulty ones I had. All good, right?
Well, remember I mentioned I've been busy? I received the tips, but didn't have any time to even look them over, much less test them out. I eventually did and they both worked fine. Except quite some weeks later I got to work on a project, and while tidying up after I noticed that one of the tips they'd sent me was a different tip from what I had. I'd purchased an ultra-performance chisel for a particular high load job, and they'd sent me the standard version of the tip instead. At that point it'd been weeks if not months since they'd sent the tips, so the fault was mine for not having noticed it sooner. Besides which they'd already been nice enough to send me replacements on short notice.
And on top of this I'd already used the tip and not noticed! That specific job I'd bought it for was to solder a SMT power inductor in an area with large heat sinking capacity. My Metcal didn't have enough power to do the job, but the
*standard* Pace tip managed it. Might have been even easier with the ultra-performance version, but getting that performance out of the standard tip was impressive.
As for what was wrong with the two faulty tips I have? Well looking at all the tips in my possession, it looks like if you're looking end on at the connector end of the tip, and were to draw a line between the contacts on the blue connector, then the black collar should protrude perpendicularly to that line. I can't be 100% certain because I wasn't able to do much more than eyeball it, but it appears that isn't the case with the two faulty tips I have. If that is indeed the problem, I'd guess it means the blue terminal ends up rotated relative to the connector in the handle and won't seat.
