9.1 Periodical inspection
The following inspections are required periodically.
(1) Cleaning the cover glass surface
Keep the cover glass surface of this detector unit clean all times. Wipe off dirt and flogging with
gauze or cloths like that.
It is more effective to impregnate the gauze with alcohol.
(2) Installation
Check this detector unit is correctly installed and fixed securely.
(3) Connections
Check the connections to all terminals of this detector unit, the operator interface/display unit, a
receiving instrument or other instruments are fixed securely.
(4) Purge air
Check flow, pressure and cleanness of air supplied for air-purging are adequate.
(5) Calibration
For maintaining the accuracy of this detector unit, the calibration of the unit once in 3 months is
recommended by using the output checker plate (Model IR-WEB or IR-WEB3: sold separately).
9.2 Self-diagnosis function
The self-diagnosis function is built in this detector unit. When an abnormal condition occurs, the
corresponding error number is displayed.
All error numbers are common to this detector unit and the operator interface/display unit.
Error
No.

condition*
-----
High limit over range Measured value is higher than
the displaying range.
Check the calibration curve data.
Check the output by the output
checker plate.
-----
Low limit over range Measured value is lower than the
displaying range.
Check the calibration curve data.
Check the output by the output
checker plate.
Er01 Nonvolatile
memory
abnormal
Writing to or reading from the
nonvolatile memory is disabled.
Return this
detector unit to
CHINO.
{
Er03 Motor
rotation
abnormal
The motor stops or rotates
abnormally.
Replace the motor.
{
Er06 Computation error
Overflow happed in computation Check the output by the output
checker plate.
{
Er07 Element temperature
abnormal
The element temperature is
abnormal.
Return this
detector unit to
CHINO.
{
Er12 Ambient
temperature
too high
The ambient temperature of the
detector unit is high
Lower the ambient temperature.
Er13 Ambient
temperature
too low
The ambient temperature of the
detector unit is low
Raise the ambient temperature.
Er14 Sample temperature
too high
The sample temperature is
higher than the correction range
Widen the correction range.
Er15 Sample temperature
too low
The sample temperature is lower
than the correction range
Widen the correction range.
Er16 Sample
low
reflection
The reflection rate of the sample
is low or the lamp is burned out.
Close the distance to the sample.
If the lamp is burned out, replace
it.
Er17 Sample
high
reflection
The reflection rate of the sample
is high.
Incline or extend the distance to the
sample.
Er20 Number of calibration
curves insufficient
for sample temperature
correction
The number of calibration
curves is insufficient for the
sample temperature correction..
Set two calibration curves setting
sample temperature or more.
9. Inspection and maintenance
(Note)
For the items filled with
{
in the self-diagnosed abnormal condition, a self-diagnosed abnormal
condition alarm is outputted from this detector unit and the operator interface/display unit.
