Failures - ION ARA H2S-H Instrument User Manual

Failures

Where the self-test fails, the detector emits an audible alarm and the LEDs will flash 10 times. The
detector will also continuously display the self-test icons on the screen.
Where the self-test fails three consecutive times, the detector will display "EOL" on the screen and
SHUT-DOWN alarm will appear. If this warning occurs, please contact ION Science.
During the detector's lifetime, the battery will be continuously monitored. If the battery voltage is too
low or below a certain level when 3 hours passed, the detector will display EO4 and SHUT-DOWN
alarm will appear. If this warning occurs, please contact ION Science.
If the detector displays EOL, it has reached the end of its operating life. Please discontinue use.
When the detector restarts shortly after downloading firmware, the detector may display "E01" or
"E02". If the warning occurs, please remove the warning by pressing the button. If this warning
occurs, please contact ION Science.
When the detector restarts shortly after downloading Firmware, the detector may display "E03". If
this occurs, please re-attempt to download the Firmware. If the "E03" error continuously occurs,
please contact ION Science.
E01 – This is when ARA is experiencing a CRC error (firmware problem or power problem) . By
pressing the button, the alarm will stop.
To solve this E01, the unit should be reset to the factory setting. Therefore, the unit should be
returned to the factory.
E02 - This is also because of firmware problem or power problem. By pressing the button, the alarm
will stop.
To solve this E02, the unit should be reset to the factory setting and calibrated. Therefore, the unit
should be returned to the factory.
