Manufacturer Narrative
|
A philips service engineer checked the system and found that the coils of the anode drive unit (adu) located in the certeray generation overheated.The adu was replaced by an improved version.Analysis of the adu showed that the adu was overheated but it did not trigger the safety chain that is located near the sides of the coils.This means that an ambient temperature of 105 degrees celsius was not reached.Philips had initiated a correction on the field due to an increase in the failure rate of the adu of certeray x-ray generators in regions with mains voltage of 480v.Philips will reclassify the field correction initiated and report it through the appropriate channels for actions.This current voltage may lead to saturation and overheating of the coils that protect the igbts (insulated gate bipolar transistor) of the adu.Overheating will make the coils lose their protective function and voltage peaks can damage the igbts leading to a loss of function of the adu.The overheating will also generate a peculiar smell that may be noticed and in some instances before the igbts actually break down.The noted smell is caused by tin plated wires contain polyurethane as lacquer insulation.This wire is according to (b)(4) and has been tested by the manufacturer in accordance with (b)(4).
