2.3 OPERATION CHECKOUT PROCEDURE WARNING 1. Please stop using this model once some function lost or the spare parts for front access panel is loose. 2. set tempera temperature ture must must be high 3
than ambient ambient temperatu temperature. re. And And then you can can
proceed this checkout procedure. Please proceed the following checkout procedure each time before operation. A. Check caster Check whether the caster can drop when lifting the radiant warmer 2cm above the ground. The drop of the caster will cause danger during transporting. IMPORTANT: At least two persons are required, one lifts the warmers, and the other has to check the casters. It needs Min. 140Kg to light the whole unit. Please support the stand with w ith block to avoid the warmer inclining if the casters cas ters drop. B. START-UP THE CONTROLLER Turn on the switch of the main power supply and controller, the controller gives sound “Ding”, at the same time, the Set Temperature indicator does not indicate, while the Air Temperature indicator and Skin Temperature indicator indicates“--.-”, indicates“--.-”,
it means the controller is doing self-test automatically for 5s.
After then, the Air Temperature indicator will displays air temperature, the Skin Temperature indicator displays the baby temperature, and Set Temperature indicator displays the former set value, and the controller can enter into the control mode automatically before turning off, and the relevant mode light will be on. C. CHECK POWER FAILURE ALARM Pull off the power cord of whole unit, the Power failure alarm should active, and the “Power” light will flash with continuous audible sound. This operation is used for checking if the power failure is normal or not. Insert the power cord again after finishing checking. IMPORTANT: Make sure that the rechargeable battery is full before usage. If not full, it may cause the power failure without the alarming indication. If full, and there is no any indication after disconnecting the main power supply, please refer to the authorized and qualified service personnel. D. CHECK HEATER Control the environment temperature at 21℃ ~ 26℃, and choose the Air Mode, Mode, and set the temperature at 33.0
℃,
and all heat power indicator are on, and heater will output heat completely.
NOTE: When the incubator works under the set state, and continue the following operation procedure.

E. CHECK THE ACCURACY OF TEMPERATURE CONTROL Select the Air Mode, Mode, and set the air temperature at 36℃, after the air temperature enters into the STEADY TEMPERATURE CONDITION, put the calibrated temperature measuring device on the position above 10cm from the center of mattress to measure the air temperature, compared with the indicated air temperature to check whether the deviation between them is within 0.8℃. F. CHECK BABY MODE Opening
Arrow
Sensor socket
The arrow sign on the plug should aim to the opening on the sensor socket so that the sensor is inserted correctly. 1. Insert or pull out the skin sensor, you must hold the plug of skin sensor, pulling the leads is forbidden. 2. Please do not bend the connection of sensor. When the Air Mode works stably, change it into the Baby Mode, Mode, set temperature at 37℃. Put the skin sensor on the center position, and the incubator will give alarm after a while. The “Sensor” alarm light will flash with continuous audible sound, and the Set Temperature indicator will show alarm code E0.8. Pull off the skin temperature sensor, the sensor failure alarm should active. The “Sensor” alarm light will flash with continuous audible sound, and the Set Temperature indicator will show alarm code E0.5. G. CHECK PRECISION OF SKIN TEMPERATURE SENSOR Put the skin temperature sensor with the mercury thermograph for the accuracy with ±0.1ºC into the 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. 2-7 I2

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 incubator temperature must be ≤38.0ºC (while when set temperature is
>
<
37ºC
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.
