In case of FMEA, the existing process control will affect both detection and occurance ratings. Example is that in case of a VFD, dusting out of modules periodically is one of the process controls. This is predominantly done to detect any conductive dust deposition on cards which will result in the failure of the VFD system. In the due course of dusting out the module, as the modules are completely opened, and again repacked any open space which may lead to future dust accumulation inside module are taken care of there by resulting in reduced occuance of dust accumulation.
