Aquatronica dosing pump and "Bus Error"

[AlanM]

So far I've only been using one of the three pumps but I wanted to sort out Mg levels over the next few days (50ppm a day to bring from 1150 to 1350)

I've tried to use the second pump but whenever I get it to do something it runs for about half a second and then AQ comes up "bus error". I've moved it to pump three which works just fine.

This sounds like pump two is faulty, is there anybody else with one of these that can just confirm that all three work exactly the same way. Sounds like a silly question but don't want to go off and go through the grief of a replacement if I've forgotton to do something simple.

I've sent a PM to wavey as well but still unread from a few days ago - is he around at the moment or just very busy? Last I knew he was going to be doing a lot of shop mail outs and visits so may just be bad timing for me.

Thanks

Alan.

ps: other than this behaviour the AQ dosing pump is a very nice unit, runs a bit on the noisy side when pumping but it's sitting in the garage so isn't a major problem. Could have done with a mounting kit as I can see that being an issue for a lot of people. Over £200 and no easy way to secure it.

I have tried all three pumps for short tests and they all worked fine, no bus error. It may be that the sensor that counts the revolutions in Pump #2 is not working.

For mounting I just used a rubber strap like the kind on a pair of Snorkeling Fins Then mounted it under the end of shelf using two screws and washers.

Following another post regarding this I though I had better close of this thread in case other people search and find it.

The unit was returned directly to ITC who turned it around very quickly. Problem sorted and has been running well ever since.

I don't know what the problem was, don't actually care, but whatever it was was sorted nice and quick.

Was the unit repaired or replaced out of curio?
