Troubleshooting

Maintenance and Inspection

The V680 Series must be inspected on a daily or regular basis so that the functions of the V680 Series can be used
in good condition.
The V680 Series consists of semiconductors that last almost indefinitely. The following malfunctions may, however,
result due to the operating environment and conditions.
(1) Element deterioration due to overvoltage or overcurrent.
(2) Element deterioration due to continuous stress caused by high ambient temperature.
(3) Connector contact faults or insulation deterioration due to humidity and dust.
(4) Connector contact faults or element corrosion due to corrosive gas.

User's Manual
Detail
Check that the supply voltage fluctuation at
the power supply terminal block is within the
permissible range.
Check that there are no frequent instanta-
neous power failures or radical voltage fluc-
tuations.
Within the specified range
Influence of vibration or impact of machines
Check that the system is free of accumu-
lated dust and foreign particles.
Check that no metal part of the system is
discolored or corroded.
Check that the system is ventilated properly
with natural ventilation, forced ventilation, or
cooling air.
Check that the panel packing is properly
attached with no damage.
Check on the I/O terminal block that the volt-
age fluctuation and ripple are within the per-
missible ranges.
Check that each device is securely
mounted.
Check that each connector is fully inserted.
Check that no wire is broken or nearly bro-
ken.
Check that no screw of the terminal block is
loose.
Check that the distance between the Tag
and Antenna is within the specified range.
Check that the GR terminal is grounded.
