state when check up the alarm about temperature
TEMPERATURE UNIFORMITY: The amount by which the average temperature at each of four points
10cm above the mattress surface differs from the Average incubator Temperature at steady
Temperature Condition. The four points are the centers of four quadrants formed by lines that divide the
width and length of the mattress surface.

water cup with the temperature as 30ºC±5ºC. Make the probe of the skin temperature sensor and the
mercury ball as closely as possible and stir enough, then read the value of mercury thermograph.
Compare the value of the skin temperature sensor and the mercury thermograph, and the deviation must
be within 0.5ºC.
NOTE: Please check again if the accuracy of the skin temperature sensor exceeds the
permissibility deviation. Please let the authorized and qualified service personnel service
machine if the accuracy the skin temperature sensor exceeds the permissibility of
deviation again.
SERVICE MANUAL FOR INFANT INCUBATOR EDITION/REVISION B/0 H. CHECK FAN MOTOR ALARM

3.2 WORKING PRINCIPLE
3.2.1 General
This section contains a functional description and detailed theory of operation of the equipment. A
system block diagram of the Controller is shown in Figure 3.2 and 3.3. The control of temperature is achieved by means of air circulation system as shown in Figure 3.1.
A controlled amount of room air is drawn through the air intake filter by means of the motor-driven
impeller on the Controller and then drawn back to motor though air return filter. Circulated air flows
through temperature sensing sensor. Temperature Controller automatically modulates the temperature
inside Hood according to the temperature sensed by the air temperature sensing sensor.
Heat output control under air mode: control the output of heater according to the air temperature
automatically;
Heat output control under baby mode: control the output of heater according to the skin
temperature automatically.

3.2.2 Temperature Control
In baby Mode, the controller will control the incubator temperature automaticlly to keep the air
temperature close to the set value. Comparing the air temperature and the air set temperature, the
controller will adjust the heat output proportion to keep the heat balance inside hood. The other probe
inside of air sensor is regarded as the isolated temperature sensor, when set temperature is < 37ºC
incubator temperature must be ≤38.0ºC (while when set temperature is > 37ºC incubator temperature
must be ≤40.0ºC ), the heater is cut off automatically.
In Air Mode, the controller will control the incubator temperature automaticlly to keep the skin
temperature close to the set value. Skin sensor is attached to the skin of patient. Comparing the skin
temperature and the skin set temperature, the controller will adjust the heat output proportion to keep
the heat balance inside hood. In the whole baby mode, the isolated temperature sensor of air sensor is
always monitor the inside temperature, when the incubator temperature is ≤40ºC, the heater is cut off
automatically.
When the baby mode is working, if the skin temperature sensor drops from the socket, the skin
temperature indicator displays “--.-”, the sensor alarm actives and the heater is cut off automatically.
3.2.3 Alarm
Alarm is used for monitoring the temperature control system state. The system will check the state
by the alarm checkout procedure. When the checked data is abnormal, it will alarm. Table 3.2 listed
alarm condition.

5.4.4 TROUBLESHOOTING FLOW CHART
Before troubleshooting, forst, please switch off, and disconnect the power cable, and then open the
top cover of warmer module and the back cover of column. And then connect the power cable and turn
onthe switch, at the same time, make sure that power +5V, +12V of controller, element, and all cables
are in good condition.In working state, press Up Key and Air mode Key , you can find the isolated
temperature and air flow temperarture in the air and set temperature indicator respectively. So it is easy
for service man to find the cause of trouble.
