What sort of repair
The 40 Norbit logic control PCB's were functionally tested at board level. Any faulty devices were repaired or replaced.
The Water Wash Control Unit, 4 Channel Flame Failure Unit, AC Power Supply Unit, Annunciator / Display Unit, and Temperature Monitor were all repaired at component level, any faulty devices were replaced, and then all were functionally tested.
What other issues did we face
The main challenge with this job was the obsolescence of many devices. The control was designed and built in the late 1970's & 1980's, using Norbit logic devices from the late 1960's. With our experience we are able to test, repair, and replace these devices. Very soon, we will be in a position to provide an alternative replacement.
What was the outcome
Using our long established test and repair methods our highly skilled team of engineers completed the work in well under the 3 week deadline. Each chassis was individually tested using custom made test rigs, designed to input the appropriate signals and record the consequent outputs.
Expected life of the reconditioned unit
All the work is covered by a 12 month warranty. But, because we replace all components that are subject to deterioration over time we would expect it to last very much longer.
