Detail
Check that the supply voltage
fluctuation at the power supply
terminal block is within the
permissible range.
Check that there is no frequent
instantaneous power failures or
radical voltage drops.
(1) and (2) Check that the
ambient temperature
and humidity are
within the specified
ranges.
(3) Check that no vibration or
shock is transmitted from any
machines.
(4) Check that the system is free
of dust accumulation.
(5) Check that no metal part of
the system is discolored or
corroded.
(1) Check that the system is
ventilated properly with natural
ventilation, forced ventilation,
or cooling air.
(2) Check that the packing is
properly attached with no
damage.
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 screw of the
terminal block is loosened.
Check that no wire is broken or
nearly broken.
Check that the distance between
the ID Tag and Antenna is within
the specified range.
Check that the GR terminal is
grounded.
Check the details of error logs.
