7-5 Maintenance Inspections
In order for your SYSMAC system to operate in optimum condition, be sure to
carry out daily or periodical inspections.
The main system components of a SYSMAC system are semiconductors, and it
contains few components with limited lifetimes. Poor environmental conditions,
however, can lead to deterioration of the electrical components, making regular
maintenance necessary.
