Inspection
Section 12-1
12-1 Inspection
In order to use the functionality of the Position Control Unit (PCU) to its
utmost, daily or routine inspection is recommended.
12-2 Routine Inspections
In order for your PCU to continue operating at optimum condition, periodic
inspections are necessary. The main components of the PCU are semicon-
ductors and have a long service life, but depending on the operating environ-
ment, there may be more or less deterioration of these and other parts. A
standard inspection schedule is once every six months to one year. More fre-
quent inspections may be advisable depending on the operating environment.
Maintain the inspection schedule once it has been set.

Criteria
Remarks
1
I/O Power Sup-
ply
Measure the voltage variations at the I/
O power supply terminal block. Do they
meet the standards?
24 VDC: 20.4 to
26.4 VDC
5 VDC: 4.75 to 5.25 VDC
With a voltage tester,
check between the termi-
nals and make sure that
the power supply falls
within the acceptable
range.

Environment
conditions
Is the ambient temperature within the
acceptable range? (When used in a
panel, the ambient temperature inside
the panel must be checked.)
0 to 55
°
C
With a thermometer,
check the ambient tem-
perature inside the panel
and make sure that it falls
within the acceptable
range.
Is the ambient humidity within the
acceptable range? (When used in a
panel, the ambient humidity inside the
panel must be checked.)
10% to 90% RH (with no
condensation)
With a hydroscope,
check the ambient
humidity inside the panel
and make sure that it falls
within the acceptable
range. In particular,
check that there is no
condensation due to sud-
den changes in tempera-
ture.
Is the PCU exposed to direct sunlight?
It must not be exposed to
direct sunlight.
Shield the PCU from
direct sunlight.
Is there any accumulation of dust (espe-
cially iron dust) or salts?
There must be none of
these present.
Remove any accumula-
tion of dust (especially
iron dust) or salts and
protect against them.
Is the PCU exposed to any spray of
water, oil, or chemicals?
It must not be exposed to
any of these.
Protect the PCU from
water, oil, and chemicals.
Is the location subject to corrosive or
flammable gases?
The PCU must not be
exposed to these.
Check for smells or use a
gas sensor.
Is the location subject to shock or vibra-
tion?
The amount of shock or
vibration must be within
the acceptable ranges
given in the specifica-
tions.
Install a cushion or other
device to reduce shock
and vibration.
Is the location near any source of
noise?
There must be no noise.
Remove the PCU from
the noise source or apply
countermeasures.
