If an alarm is generated, such measures as turning off the heater power are not carried
out. The alarm is released when the cause for the alarm is eliminated. However, Alarm
10 and/or Alarm 11 may be generated at the same time as Error-2 (heater temperature
error). In such a case, the measure taken for this error has priority.
If the converter power is turned off after an alarm is generated and restarted before the
cause of the alarm has been eliminated, the alarm will be generated again. However,
Alarms 6, 7, and 8 (alarms related to calibration) are not generated unless calibration is
executed.
