  • Page 228 Datex-Ohmeda ADU Figure 2 Electrical connections of the A-FGC1 Pneumatic Connections The module is supplied with pressurized Air, N O and Oxygen. All gases have the same supply pressure as the wall connector (flow losses taken into account). The gases are filtered in the wall gas unit. There are not any non-return valves between the inside of the wall connector and the module pressure measuring point.

  • Page 231: Description Of The Flow Control Section

    Technical description A-FGC1 Description of the flow control section Pressure regulators The fresh gas flow range is set with three regulators for each gas. The regulators control the secondary pressure to a fixed level that is independent on the pipeline pressure. The O O and Air lines (1) are supplied to the A-FGC1 at normal pipeline pressure and separate gas regulators (3) for each gas reduce the pressure to the gas controls of the unit.

  • Page 232: N 2 O Limiting Control

    Datex-Ohmeda ADU (no voltage), the sensor ports are connected to opposite sides of the restriction. The valve compensates pressure sensor zero drift and is connected to two lines. One line is upstream the flow restrictor, the other line is downstream. The valve can pneumatically short-circuit the pressure sensor ports, thus giving the zero pressure (= zero flow) signal.

  • Page 233: N 2 O Pressure Sensor

    Technical description A-FGC1 O pressure sensor The N O pressure sensor (2) supervise the N O pipeline pressure to the A-FGC1. If the pressure falls below 2.5 bar will the alarm ´N O supply pressure lost´ be initiated. In the same time will the N gas delivery be cut-off and Air will automatically be selected by the N O/Air valve (8).

  • Page 234: Vaporizer Section

    Datex-Ohmeda ADU Vaporizer section Theory of the vaporizer The electronically controlled vaporizer is integrated with the gas flow controls in the A-FGC1 module. When the vaporizer is used, the gas flow from the flow controls is split into a bypass flow and a liquid chamber flow i.e.

  • Page 235: Definitions Of Components In The Vaporizer Section

    Technical description A-FGC1 The gas composition of the bypass flow and the gas entering the vaporizer is known and it is used to compensate the flow transducer output, which means that the gas composition has no effect on the anaesthetic output or accuracy as it has in conventional vaporizers. The Bypass flow and the Cassette outflow (= Fresh Gas Flow) are then passing a mixing chamber before reaching the Fresh gas outlet.

  • Page 236: Agent Control

    Datex-Ohmeda ADU Agent control The fresh gas from the flow controls is divided into: • The bypass flow measured by the Bypass flow measurement unit (1) • The cassette outflow measured by the Cassette flow measurement unit (2) The cassette and bypass flow measurements are used to control the vaporizer output and for safety purposes to check the validity of the mixer flow measurements.

  • Page 237: Agent Concentration Control

    Technical description A-FGC1 The liquid prevention valve (14) prevents liquid from the cassette to enter the fresh gas line in a failure situation. The valve is a polypropylene ball located in the vaporizer valve block beside the outflow channel. The liquid will lift the ball up and seal it to the valve seat. The cassette pressure relief valve (8) opens the channel to the scavenging line, if a high pressure is detected in the cassette or the liquid level measurement device detects overfilling.

  • Page 238: Liquid Chamber, Aladin Cassette

    Datex-Ohmeda ADU If the cassette is empty or overfilled, a user alarm is displayed: If the cassette is overfilled to a 160% according to maximum limit (100% = 250 ml), the alarm message ‘Draining Cassette´ is displayed. The alarm message will disappear when the cassette is 120% over the maximum limit.

  • Page 435: Functional Description Of The Circuitboards

    Technical description A-ELEC Functional description of the circuitboards Mains Connection Board The function of the mains connection board is to supply mains voltage to the mains transformer and to the external power outlet. The mains voltage is connected to the board through the EMI filter. The same kind of filter is connected to the board’s mains voltage external outlet.

  • Page 436: Mother Board

    Datex-Ohmeda ADU Mother board The mother board includes data, address, control and power buses which are needed for the communication between the main CPU board and the other boards. The ADU is powered by VRAW voltage from the rectifier board. The mother board contains two FET switches which couple VRAW to the power bus (VBUS) when in mains use.

  • Page 437: Rectifier Board

    Technical description A-ELEC Rectifier board The function of the rectifier board is to rectify and filter the mains transformer output. There are also comparators and switches that will turn off the output if the voltage is below 18 V or above 36 V.
  • Page 438 Datex-Ohmeda ADU The main CPU measures battery voltages, currents and temperature. There is an A/D-converter and a CPU bus interface logic for that purpose. These circuits are supplied from a separate +5V supply powered from the VBUS. Signals from the battery voltage and current measurement, are amplified and scaled to the A/D- converter input range of 0 to 10V.

    Technical description A-ELEC Mains / Battery switching logic The batteries are disconnected if: • Mains power is available and the ADU is switched on. • The ADU is in standby mode. • The ADU was running on battery has turned itself off after the batteries are discharged. In all other cases the ADU gets its power from the batteries.
