Preventive Maintenance
Preventive maintenance consists of periodically cleaning the front panel, the
terminal module, and performing the Operator’s Check. Clean the module
and terminal module yearly, or more often if the module is used in very
dusty or humid areas. Disassembly of the module is not recommended for
cleaning. However, if the module is disassembled for repair or
reconfiguration, the printed circuit board assemblies (PCAs) can be blown
off with a properly grounded airgun. Remove the terminal module cover to
blow dust off the terminal printed circuit board and case. Table 3-1 shows
the recommended cleaning equipment and supplies.
