Peter - Jimmy and I discussed this matter earlier today here in the USA. The Serial Number you refer to on the attached document 4658100003 is from original sales order 3670940 (qty 3 unit sold).
Shortly after the unit shipped, it was found that the Power Module in the original control boxes were built incorrectly. Call 190 476 was created along with Parts Order 3700140 for qty 3 new Power Module boards to replace the original one sent in the control boxes.
Was this accomplished? Did your company replace the Power Modules as instructed? Part 148493
Answers: No - Please find the boards we shipped you and install these into the control boxes.
Or are we talking about the order for 6 units form sales order # 3686730 and you have given us an incorrect serial number on the attached document?
