(50 or 60 Hz). The output signal is provide to the Control Board. The Relay Board provides the +5v standby power supply to the entire Giraffe system. A +5V regulator generates the +5V standby from the diode OR combination of the system +12V power supply or the backup battery.
Page 32: Display Driver Board / El Display
The elevating base motor control circuits consist of a series of three relays. For the Giraffe Incubator, the speed relay and the E/H select relay are always switched to the same position. The speed relay connects the 15 volt secondaries of the toroidal transformer in a series (drive at 30 volts) for raising or lowering the elevating base.

Chapter 1: Functional Description pulse for the whole display frame (YD). The controller handshakes with the 80C188 using the READY line to eliminate any lost data during display refreshes. 1.4 LED Board The LED Board contains five display banks and two display drivers. One of the display drivers controls the patient temperature and air temperature display banks.
Page 34: Datalink Option
Chapter 1: Functional Description The toroidal transformer is used to buck the mains voltage down to the range required for the elevating base motor. The primaries mains input comes from the relay board and is switched by safety relay 2. The dual primaries are connected in parallel for 115 volt operation and in series for 230 volt operation.
