In order that your SYSMAC system operates 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. Environmental conditions, how-
ever, can lead to electrical element deterioration, making regular maintenance
necessary.
The standard period for maintenance checks is 6 months to 1 year, but depend-
ing on the environment checks may need to be more regular.
If the criteria are not met, adjust to within the specified ranges.
Details

voltage fluctuation is within
the standard at the power
supply terminal.
Is the ambient temperature
inside the panel
appropriate?
Is the ambient humidity
inside the panel
appropriate?
Has dirt or dust collected?
Is the voltage fluctuation
measured at the I/O
terminal within the standard
range?
Are all units securely
installed?
Are all connection cables
and connectors inserted
completely and locked?
Are any of the external
wiring screws loose?
Are any of the external
