Function Description
09.99 Page 27 of 49
In the event of suppressed audio alarm, the corresponding alarm LED and the central alarm
LED (not available on Incubator 8000 SC / NC with software version 10.n) light up
continuously; the horn is off. The yellow LED above the switch-off button indicates that the
alarm has been acknowledged.
Should a further alarm situation occur during the course of alarm suppression, the audio alarm
is immediately re-activated and the alarm suppression time reset. Depending on the type of
fault, this alarm can also be suppressed again. The reactivation time for the first alarm tone is
then extended by the difference in time between the two alarms.
2.3.1.2 Sensor alarms, fan failure alarm
Faults in the sensors for air temperature, skin temperature, oxygen concentration (Inc. 8000 IC
only) and humidity (Inc. 8000 SC / IC only) as well as fan faults result in the following alarm
messages:
- Three dashes (air and skin temperature) or two dashes (02, humidity) flash in the
respective actual value display.
- In the event of a fan fault the air temperature actual value flashes.
- The corresponding alarm LED flashes.
- Continuous horn tone (cannot be deactivated).
With respect to the sensor alarms for oxygen concentration (Inc. 8000 IC only) and humidity
(Inc. 8000 IC only), the alarm is reset following switch-off of the module concerned and further
operation can be continued with the other functions. The same applies to the skin temperature
module, however, the defective sensor must first be removed in this case.
2.3.1.3 Module fault
Hardware faults affecting a single module result in the following alarm messages for the skin
temperature, oxygen concentration and humidity modules:
- The letters "Err" flash up on the corresponding actual or desired value display if the module
is switched on or appear in steady form if the module is switched off.
- INOP-LED lights up if module is switched on.
- Continuous horn tone (cannot be deactivated) if module is switched on.
The functions of the other modules which are working properly are retained.
