12.2 Displays and Remedies When Alarms are
Generated
12.2.1 Alarm Types
When an alarm is generated, the alarm indication blinks in the display to notify of the alarm
(Figure 12.3). Pressing the alarm indication displays a description of the alarm.
Alarms include those shown in Table 12.2.

Alarm
Code
Alarm Type Occurrence Conditions
Alarm 1 Oxygen concentration alarm Measured oxygen concentration value exceeds or falls below
the preset alarm limits. (refer to Section 8.3, Setting Oxygen
Concentration Alarms).
Alarm 6 Zero-point calibration coefcient
alarm
In automatic or semi-automatic calibration, zero correction
ratio is outside the range of 100 ±30%. (refer to Section 9.1.3,
Compensation).
Alarm 7 Span-point calibration coefcient
alarm
Span correction ratio is outside the range of 0±18% (refer to
Section 9.1.3, Compensation).
Alarm 8 EMF stabilization time-up alarm In automatic or semi-automatic calibration, cell voltage does not
stabilize after calibration time is up.
Alarm 10 Cold junction temperature alarm Temperature of the cold junction placed in the detector terminal
box falls below -25 ºC or exceeds 155 ºC.
Alarm 11 Thermocouple voltage alarm Generated when thermocouple voltage exceeds 42.1 mV (about
1020 ºC) or falls below -5 mV (about -170 ºC).
Alarm 13 Battery low alarm Internal battery needs replacement.
If an alarm is generated, actions such as turning off the heater power are not carried out. The
alarm is cancelled when the cause of the alarm is removed. However, Alarm 10 and/or Alarm 11
may be generated concurrently with Error2 (heater temperature error). In this case, the operation
when the error occurs has priority.
If the power to the converter is turned off after an alarm is generated and the converter is restarted
before the cause of the alarm has been removed, the alarm will be generated again. However,
Alarms 6, 7, and 8 (alarms related to calibration) are not generated unless calibration is executed.
