Detail
Check that the supply voltage fluctuation
at the power supply terminal block is
within the permissible range.
Check that there are no frequent instan-
taneous power failures or radical voltage
drops.
Check that the ambient temperature and
humidity are within specified range.
Check that no vibration or shock is trans-
mitted from any machines.
Check that the system is free of dust
accumulation.
Check that no metal part of the system is
discolored or corroded.
Check on the I/O terminal block that the
voltage fluctuation and ripple are within
the permissible ranges.
Check that each device is securely
mounted.
Check that each connector is securely
connected.
Check that no wire is broken or nearly
broken.
Check if grounding to 100 Ω or less has
been done.
Criteria
