If errors occur, the following contents are displayed.
When errors No. 1 to No. 3 and No. 10 occur, analyzing block error contact output is closed.
When errors No. 4 to No. 9 occurs, calibration error contact output is closed.
<Troubleshooting at the occurrence of error>
When errors No. 1 to No. 3 and No. 10 occurs, the analyzer is faulty. Contact your dealer or our sales
office.
When errors No. 4 to No. 8 occurs, the calibration procedure may be incorrect.
Check the following items, and if error still occurs, contact us as shown above.
(1) Is the calibration gas supplied in the analyzer?
(2) Does the calibration operation match the supplied gas? (For example, zero calibration is per-
formed while flowing the span gas.)
(3) Does the supplied gas concentration match the gas concentration set at the calibration con-
centration setting?
Also, when errors No. 5 and No. 7 occurs, you can perform calibration forcibly, following the proce-
dure shown below. Use it as fault recovery when calibration fails and calibration contents are missed.
Light source/motor rotation is
faulty.
Error No.1
•
Infrared light source is faulty.
•
Sector motor is not properly run or is stopped.
•
Amplifier circuit is faulty.
Measured values fluctuate too much
during zero and span calibration.
Error No.8
• Calibration gas is not supplied.
• Time for flowing calibration gas is short.
Calibration is abnormal during auto
calibration.
Error No.9
• Error corresponding to No. 4 to No. 8
occurred during auto calibration.
Output cable connection is
improper.
Error No.10
•
DIO circuit is failure.
• Internal wiring to the DIO circuit is broken.
Span calibration is not within the
allowable range.
Error No.6
Amount of span calibration
(difference between indication value
and calibrated concentration) is over
50% of full scale.
Error No.7
• Span gas is not supplied.
• Calibrated concentration setting does not
match cylinder concentration.
• Zero calibration is not performed normally.
• Span is deflected much due to dirty cell.
• Detector sensitivity has deteriorated.
Zero calibration is not within.
Error No.4
Amount of zero calibration
(indication value) is over 50%
of full scale.
Error No.5
• Zero gas is not supplied.
• Zero is deflected much due to dirty cell.
• Detector is faulty.
