1. Defective fans in combination with an internal leakage may lead to elevated O
Risk of fire!
2. The priority of the alarm message depends on the severity of the fresh gas shortage.
3. If the alarms "VT NOT ACHIEVED" or "PINSP NOT ACHIEVED" occur additionally, a fresh gas deficiency in the system is remedied by
entraining ambient air. Monitor concentrations carefully as the breathing gas will be diluted.
4. Displayed in Standby mode only.
5. At high ventilation frequencies, the measured value cannot keep up completely with the gas concentration for reasons due to the system.
* Alarm can be downgraded to specified lower priority or canceled.
