If machine serial tag referring to 3Ph, 208-240V then you cannot apply 3Ph, 380V. In order to use 3Ph, 380V supply you have, machine needs to be retrofitted to work with this voltage. If you apply 380V without voltage conversion, you will damage som

Thank you Bilal, i am aware that you can't run 3x240 machine at 3x380V, that is why i have delta-delta transformer. It was phase sequence after all, and machine is now running. Thank you all for your help.

1. Why isn't an electrician doing this? 2. Did you measure phase-to-phase voltage between each phase at the machine? 3. Phase rotation only affects the 3-phase motors. If it's out of sequence, the motors will spin backwards but everything else sho

Does anyone have used Heller 1700SX (2001) or Heller 1700EXL (1999) for lead free? I found some references in this forum for Heller 1500 but anything for last ovens, just wondering if they can be used though they may run slow.

Thanks for your information. What model year is your Heller 1700?. It seems that you can find same model (1700EXL) from 1999 to 2008 but there should be some differences between them which I don't know. Just want to make sure you are not running a ne

We are using a Heller 1707EXL for both lead and lead-free assemblies with no problems. The zones can reach the temperatures needed for lead free. The belt speed can be adjusted so I'm not sure about your "run slow" comment. Maybe the 1707 is diffe

I set up some lead-free profiles on a new Heller1700xxx (Compact series), do not know if this is same model you refer to. Can be done, yes speed is a little slower than longer Heller Versions due to zones being so narrow, but doable. Of course all de

Could I get some help please? I have a Heller 1700EXL, 7 zone oven and I'm trying to figure out a better way of off-loading my completed boards. What I have now is simply a small table at the exit of the oven with about an 8" drop from the top of

I have replaced few of those, on 1500, 1700, and 1809EXL. It should not take you more than couple of hours. Only problem I do see you running into is maybe rusted/welded screws for the elements from heat.
