6 INSPECTION AND MAINTENANCE
6.3 Periodic Inspection
The items that must be inspected one or two times every 6 months to 1 year are listed
below. When the equipment is moved or modified, or layout of the wiring is changed,
also implement this inspection.
Table 6.2 Periodic Inspection
Item Inspection item Inspection method Criterion Action
Ambient
temperature
0 to 55 °C (32 to 131 °F)
Ambient humidity 5 to 95 % RH
1
Ambient environment
Atmosphere
Measure with a thermometer
and a hygrometer.
Measure corrosive gas.
No corrosive gases
If the controller is used in the
control panel, temperature
within the control panel is
equivalent to ambient
temperature.
85 to 132VAC
170 to 264VAC
2 Power voltage
Measure a voltage across the
terminals of 100/200VAC and
24VDC.
15.6 to 31.2VDC
Change the power supply.
Looseness, rattling
Move the module to check for
looseness and rattling.
The module must be installed
fixedly.
Retighten the screws.
If the CPU, I/O, or power
supply module is loose, fix it
with screws.
3
Installation
Adhesion of dirt and
foreign matter
Check visually.
Dirt and foreign matter must
not be present.
Remove and clean.
Looseness of
terminal screws
Try to further tighten screws
with a screwdriver.
Screws must not be loose. Further tighten.
Distance between of
crimping terminals
Check visually.
Crimping terminals must be
positioned at proper intervals.
Correct.
4
Connection
Looseness of
connectors
Check visually. Connectors must not be loose.
Retighten the connector
fixing screws.
5 Battery Preventive maintenance
Even if the lowering of a
battery capacity is not
shown, replace the battery
with a new one if a service
life time of the battery is
exceeded.
6
Cooling fan unit
(Q173CPU/Q172CPU
only)
Check visually.
No vibration, howl and noise.
(The service life time of the
cooling fan unit: when the
number of the revolution
lower than the 20% of the
initial time. )
Replace it with a new one. If
a service life time of the
cooling fan unit is exceeded,
