DESIGNATOR NAME FUNCTION RANGE<br />
T1 FIO2 ADC input of O2 Sensor 0.25-0.51V (In AIR)<br />
T2 Pgas Pressure switch of gas supply,<br />
low active<br />
T3 FL_INSP Inspire Flow signal 0.20-0.30V (0 flow)<br />
T4 Pair Absolute Pressure of air way 1.7-2.1V (atmospheric<br />
pressure)<br />
T5 FL_EXP Expire flow signal 0.20-0.30V (0 flow)<br />
T6 Fm_fl Flow of flowmeter 0.25-0.51V (flowmeter off)<br />
T7 AD-Exhale PEEP valve, current feedback Level depends on PEEP<br />
setting and vent mode. No<br />
activity may indicate open<br />
connection from driver to<br />
valve (ie. bad cable)<br />
T8 Volt Internal power inspect<br />
T9 MUTE Not used<br />
T10 M-EN Manual/Auto mode select<br />
T11 V-EN Valves enable Input Global valve enable signal.<br />
Must be active for valves to<br />
operate.<br />
T12 EX-DA Exhale DA output<br />
T13 In-DA Inhale DA output<br />
T14 GS_ST gas supply status, high active<br />
T15 XVI unamplified version of T7<br />
T16 IVI unamplified version of T28<br />
T17 MVI Manual-Valve current feedback<br />
T18 IVG Proportional valve drive signal, Level depends on machine<br />
drives T16 and T28<br />
settings.<br />
T19 XVG PEEP valve drive signal - drives Level depends on PEEP<br />
T15 and T7<br />
setting and vend mode.<br />
T20 PADJ Power 4.8V 4.8V<br />
T21 P24V Power 24V 24V<br />
T22 P12V Power 12V 12V<br />
