Page 29: Chapter 1: Functional Description
Chapter 1: Functional Description This chapter provides a functional description for the Giraffe OmniBed, including sections representing each of the four boards. Refer to “Figure 1-1 Block Diagram” and section “6.5 Wiring Diagrams” when studying this chapter. 1.1 Control Board The Intel 80C188EC microcontroller is an enhanced X86 processor with many on-board peripheral features, such as a interrupt controller, DMA controller, peripheral chip select driver, programmable timers, etc.

Page 31: Relay Board
Chapter 1: Functional Description The overtemperature circuit compares the air temperature to a reference level, generates an interrupt, and turns off the heat if the air temperature is higher than the reference level. The overtemperature circuit requires varying its voltage levels to accommodate various thermistor measurements. This is because the calibration is digital (no potentiometer).
Page 32: Display Driver Board / El Display
Chapter 1: Functional Description is present, the battery is biased out of the circuit with the diode and is merely being trickle charged though a resistor. The battery charges only when the unit is powered on. The motor driver circuit turns the DC motor coils in the incubator airflow fan motor on and off based on feedback from the hall effect position sensors.
Page 33: Led Board
Chapter 1: Functional Description The RS-485 integrated circuit converts the RS-232 TTL signals from the microcontroller to RS-485 signals for the bus. The timekeeping RAM has a battery integrated into the chip so that the time and date run are kept current even with the power off.
Page 34: Rail And Heater Door Switches
Chapter 1: Functional Description The humidifier isolation transformer isolates the humidifier heater from the mains voltage. The primaries mains input comes from the relay board and is switched by safety relay 2. The dual primaries and secondaries are connected in parallel for 115 volt operation and in series for 230 volt operation. The isolated secondaries output voltage is equal to the mains input voltage..

Chapter 1: Functional Description to provide a 2500 VRMS isolated serial interface to meet the logic levels specified by EIA RS-232D and CCITTV.28. The MAX250 and MAX251 (U1 and U2), together with two 6N136 optocouplers and transformer TR1, form an isolated RS-232 transmitter and receiver. The MAX250 connects to the non-isolated or “logic” side of the interface, translating logic signals to and from the optocouplers, while the MAX251 resides on the isolated or “cable”...
Page 36 Chapter 1: Functional Description to the concentration of oxygen. Humidity and temperature sensors located in the sensor plug are used for voltage compensation. A fan mounted to the sensor-housing door is activated when the temperature reaches 50 degrees C. This fan circulates air to keep the sensors below the maximum allowable operating temperature, about 55 degrees C.
Page 37: Humidifier
Chapter 1: Functional Description 1.9 Humidifier Refer to the following diagram. Water enters the insulating cylinder (1) through a small hole in bottom. Steam rises along the heater cartridge protective insert (2) and is channeled between the heater mount (3) and the ramp block (4) and out the steam port (5).
