External Peripheral
power (10VA) circuitry
2-20
This circuitry sends 10VA limited 12.5 VDC power to the following subsystems:
Note:These subsystems do not receive power directly from the PCB. Only the
Anesthesia Controller Board and Display Unit receive power directly form the PCB.
• Ventilator Interface Board (VIB)
• Electronic Gas Mixer (Mixer)
• Agent Delivery Board (ADB)
• M-Gas Power Board
• External Peripheral #1
• External Peripheral #2
• Accessories (Task Light)
Hardware Reset will happen if:
• Watchdog is not reset
• During Anesthesia Controller Board Power-up (Normal)
• If the voltages produced on the board become out-of-range (3.3, 2.5, or 1.8VDC).
If the system evokes a Hardware Reset, all the peripheral devices, which is controlled
by the Anesthesia Controller Board, loose power. All communication with these
peripherals devices will cease to continue.
