Periodic Inspections

10-1 Periodic Inspections
SYSMAC LINK Units must be inspected on a regular basis to ensure correct
operation. SYSMAC LINK Units are built primarily of solid-state components
and contain almost no parts subject to wear. Nevertheless, the life span of
some solid-state components can be shortened as a result of adverse envi-
ronmental conditions.
We recommend that the following points be checked at least once every 6 to
12 months as part of a standard inspection program. Ambient conditions
should be checked more frequently. If any of these items deviate from the pre-
scribed standards, take appropriate action to correct the condition.
We recommend that users have backup Units available to make repairs and
minimize down-time if a problem occurs in a SYSMAC LINK Unit.
10-2 Handling Precautions
Please observe the following precautions in the event of a problem:
• Always turn OFF the power when replacing a SYSMAC LINK Unit.
• If a SYSMAC LINK Unit fails, replace it with a new one and immediately
verify that the new Unit is working properly.
• When returning a malfunctioning SYSMAC LINK Unit for repair, please
attach a detailed description of the problem to the Unit and return it to the
sales office nearest you (see listing at the end of this manual).
• If you suspect that a poor connection is the cause of a malfunction, clean
the connectors using a clean, soft cloth and industrial-grade alcohol.
Remove any lint or threads left from the cloth, and re-mount the SYSMAC
LINK Unit.
