5.13 ALARMS
All the settings and readings taken from the sensors are shown on the graphic monochrome display in the centre of the Control Panel. Different settings and visualizations
are accessible by using the different displays available on the monitor.
The high part of the liquid crystal display is dedicated to visually displaying descriptions of
the alarms:
• HIGH TEMPERATURE, is seen when the air temperature inside the hood exceeds
the set temperature by 1°C or when the skin temperature exceeds the set temperature by 1°C.
Otherwise, there is an alarm controlled by the micro-processor which is activated
when the air temperature inside the incubator exceeds 39.5°C. This last type of
alarm cannot be Muted.
• LOW TEMPERATURE, when the air temperature in hood is inferior of 3°C
respecting to setting temperature, or when the setting temperature is inferior of 1
°C respecting to sertting temperature.
• MAX TEMP, is controlled by a protective analogue circuit independent from the
micro-processor and is activated at 40°C.
• HIGH HUMIDITY, (when requested) indicates the state of the alarm for high percentages of humidity, and is activated when the level of humidity reading is 10%
higher than the pre-selected value.
• LOW HUMIDITY, (when requested) indicates the state of the alarm for high percentages of humidity, and is activated when the level of humidity reading is 10%
lower than the pre-selected value.
• HIGH OXYGEN, (when requested) indicates the state of the alarm for high oxygen
concentration, and is activated when the oxygen concentration reading is higher
than the pre-selected maximum value.
• LOW OXYGEN, (when requested) indicates the state of the alarm for high oxygen
concentration, and is activated when the oxygen concentration reading is lower
than the pre-selected minimum value.
• FAN FAILURE, Blocked fan alarm is activated if the air circulation fan is blocked
or slows down. In this case both the visual and auditory alarms are activated, (not
mutable) and heating is suspended.
• AIR PROBE FAILURE, this alarm is activated for a broken air probe when the
temperature difference between the air sensor probe and the test sensor located
at the same place is greater than 1°C.
• SKIN PROBE DISCONNECTED, this alarm is activated when the Skin1 sensor
probe becomes disconnected and the incubator is in Skin thermo-regulation Mode,
in this case the thermo-regulation passes to Air Mode with the temperature set
at 33°C.
• PROBE CABLE DISCONNECTED, disconnected probe cable alarm is activated
when the probe group wire is disconnected. When this occurs heating and all of
the machine’s other functions are suspended.
• OXY PROBE DISCONNECTED, (when requested) the Disconnected Oxygen
Sensor Probe Alarm is activated when the oxygen sensor probe is disconnected.
The alarm can be silenced by pressing the Mute button.
• WRONG OXY PROBE POSITION, (when requested) Alarm for the incorrect positioning of the oxygen sensor probe. If it is activated, not having done the calibration, the sensor probe is positioned in the probe door in the hood or in the small
