York YVVA

[Scottish Iceman]

Hi there guys.

I was wondering if anyone come over a fault on a York YVVA Chiller of 'vsd run relay' also had previous faults on 'HPCO' initially though may be related to the 2nd hp switch but have checked this out and okay. Also Hp switch number 1 is fine.

If anyone can help would be great

Cheers

Hi Iceman the same problem appears on the ICIV chillers, just make sure that the connectors on the HP switches are tighten up because the 110V is passing from the HP switches to energise the pre-charge to the VSD, and is YVAA and not YVVA

Cheers
