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.
The standard period for maintenance checks is 6 months to 1 year, but more fre-
quent checks are required if the PC is operated in more demanding conditions.
If the criteria are not met, adjust to within the specified ranges.
