Control systems mechanical problem diagnostics

The procedural controls applicable for the preventive maintenance and repair of the hardware provide a mechanism for anticipating problems and, as a consequence, possible loss of data. Modem hardware usually requires minimum maintenance because electronic circuit boards, for example, are usually easily replaced and cleaning may be limited to dust removal. Diagnostic software is usually available from the supplier to check the performance of the computer system and to isolate defective integrated circuits. Maintenance procedures should be included in the organization s standard operating procedures. The availability of spare parts and access to qualified service personnel are important for the smooth operation of the maintenance program.
