10 2 Theory of operation AC distribution components The AC distribution components include a power cord AC panel power switch interfacing cables, wires, and components Mains (AC) power (or facility power) is applied through the power cord to the AC receptacle and main and auxiliary circuit breakers. From the main circuit breaker, power is applied through the AC filter directly to the power supply. Power to the power supply bypasses the power switch, enabling the power supply to continually charge the BPS. When the power switch is set to off, the secondaries that power the ventilator electronics are not active. From the auxiliary circuit breaker, power is applied via the power relay to the compressor compartment AC receptacle and the humidifier receptacle. The compressor compartment power cord plugs into receptacle J4, supplying AC power to the compressor unit, while the humidifier receptacle is intended to power an optional humidifier Power cord The 840 Ventilator System includes a detachable power cord. The power cord has an IECstandard, three-prong connector. The plug end varies, corresponding to different country requirements AC panel The AC panel ( Figure 2-45 and Figure 2-46), a single field-replaceable unit (FRU), includes components that apply AC to the ventilator head, compressor unit, and optional humidifier. The AC panel includes AC receptacle, circuit breakers CB1 and CB2, AC filter, power relay K1, compressor receptacle J4, and potential equalization connector. A humidifier receptacle (), which is connected to but is not a part of the AC panel, is on the front of the ventilator. The AC receptacle () receives facility AC power via the power cord. Warning Ensure that the power cord retainer bracket is properly installed and secures the power cord to the AC receptacle (). The AC panel houses two push-to-reset type circuit breakers. The 5 A main circuit breaker (CB1) limits current to the power supply. The 10 A ( V) or 5 A ( V) auxiliary circuit breaker (CB2) limits current to the compressor and humidifier circuits. The AC filter reduces AC line noise to and from the ventilator. The power relay (K1) switches power to humidifier receptacle and compressor receptacle J4 when the power switch (S1) is on. The relay is powered from a dedicated +12 V power supply output, which is active when the power switch is on. The compressor receptacle (J4) receives AC power via K1 and provides the AC power outlet for the compressor power cord. The humidifier receptacle () receives AC power via K1 and provides an AC power outlet for the humidifier power cord. The potential equalization connector () interfaces the equipment and the potential equalization bus bar Puritan Bennett 800Series Ventilator System Service Manual

12 2 Theory of operation Compressor unit operation The 806 compressor operates in two modes: run and standby. A special start-up sequence ensures that the motor starts with an unloaded compressor head Run mode When AC mains power is > 80% of nominal, the compressor is available for use if wall air is unavailable or the pressure is < 26 psig. In run mode, the compressor acts as the air source for the ventilator, continuously supplying air to meet the ventilator s full flow requirements (200 L/min peak flow, 2.5 L breath volume). When accumulator pressure reaches 27 psig, SOL3 is energized, venting excess flow to assist transporting water vapor out of the air dryer. The solenoid becomes de-energized when the pressure drops below 22.5 psig (see Figure 2-85). This cycle repeats as pressure rises and falls in the accumulator Standby mode The compressor enters stand-by mode when there is sufficient wall air pressure to supply the ventilator. When the ventilator is powered up, it runs through POST and detects the presence of the compressor. The compressor turns on and pressurizes the accumulator. During this cycle, the green compressor ready indicator on the GUI illuminates when the accumulator pressure reaches at least 13 psig. When the accumulator pressure reaches 27 psig, the compressor turns off. If pressure in the accumulator drops below 22.5 psig (due to small leaks in the system or cooling of compressed air), the compressor starts and recharges the accumulator to 27 psig (see Figure 2-85) Puritan Bennett 800Series Ventilator System Service Manual
