Maintenance and Inspection
To maintain the CF Reader/Writer in optimum condition, daily or periodic inspections are required.
The CF Reader/Writer mainly consists of semiconductor components, which have a long life. The following
malfunctions, however, may occur depending on the environment and operating conditions.
(1) Deterioration of elements due to overvoltage or overcurrent
(2) Deterioration of elements due to long-term stress caused by operation in locations with high ambient
temperatures
(3) Deterioration of insulation or imperfect connector contact due to humidity or dust
(4) Imperfect connector contact or corrosion of elements due to corrosive gas.
