If there is conductive material nearby
, blow air through the CPU
Unit.
Noise If the error did not result from the above causes, cycle the power
to the Controller and see if that resets the error. If the error oc-
curs frequently
, check the FG and power supply lines to see if
noise is entering on them. Implement noise countermeasures as
required.
CPU Unit failure If the error persists even after you make the above corrections,
replace the CPU Unit.
