Turbo Power: Why is the Turbo turning off and restarting after 30 seconds?
The Turbo is protecting itself from low battery voltage. If the bus voltage drops below 12V, the Turbo will turn itself off and try again every 30 seconds. If this is happening on the ground, you need to charge the battery. If this is happening in the air, it is due to a weak battery or low charging by the alternator/generator. Warning, do not use a weak trickle battery charger to run the Turbo unless the trickle charger can provide more than 10Amps of current; running the Turbo on a weak trickle charger will break the Turbo pump.
Turbo Faults: What is the cause of the button light extinguishing or the fault on my AHV avionics?
The button light will extinguish and a fault will trigger on the AHV avionics for one of the following events:
Fault Codes
1 - over temperature: temperature over 65C and the Turbo will turn off until the temperature is less than 40C.
2 - low concentrator flow under 0.5 LPM: the Turbo is not making concentrated oxygen or the flow of concentrated oxygen is too low
3 - temperature warning: temperatures is above 40C, but the Turbo will continue to operate until reaching 65C.
4 - injection flow: oxygen injection from the bottle is not working and the bottle may be empty or disconnected.
5. N/A
6 - voltage out of range: the voltage is either under 12V or over 15V and the Turbo will turn off for 30 seconds before restarting.
For fault code 6 regarding injection, one common cause of fault is when the injection mode is set to come on automatically above an altitude threshold. The default may be 10k feet MSL, for example. If there is no oxygen in the bottle or the bottle is not hooked up properly, the injection mode will come on automatically above the altitude threshold and fault with no oxygen bottle. This threshold can be adjusted in the AHV configuration mode under TUR TRIGGER.
Note that Version 53 of the AHV software adds more support for fault code basis in the user interface.
Turbo Placement Orientation: Can the portable unit be mounted in any orientation or only in the vertical orientation?
Since the unit is designed to be portable, it should be positioned within easy reach so you can turn it on and off, connect your cannulas, and adjust the flow rate as needed. The flow rate can be monitored through the Aithre Connect app.
Once you have set and verified the correct flow rate, and can confirm or adjust it as needed during flight, the unit may be placed in an orientation other than upright. Just ensure that the ventilation openings remain unobstructed and that adequate airflow is maintained around the unit.
AHV Avionics Version and HealthView III: Why isn't the AHV or ATD recognizing my HealthView III?
The HealthView III has a new protocol that is not recognized by older AHV software versions. The AHV requires software version 53 or newer to recognize the HealthView III. Verify your software version in the configuration settings of the AHV by pushing the inner knob for 3 seconds. Navigate to System -> About. Download the new software from our website onto a microSD card and insert the card into the AHV slot. Recycle power and the update will happen automatically.
Additionally, after verifying the version 53 or better, the AHV must be configured for whichever port is used for the HealthView III. There are two ports on the back of the AHV avionics and you must designate which one is being used for the HealthView III: top or bottom.
Aithre Boom Cannula: How far does the boom cannula arm need to be pushed into the blue adaptor? My sheething is bunching.
The adaptor is designed and tapered on the interior to prevent the arm from being pushed in too far and blocking the internal channel. Just a gentle insertion with a little twist is needed to get it in and it will hold. If the sheathing bunches you have pushed too hard and too far, smooth out the sheathing and try again. Max insertion is 5mm.
Aithre Boom Cannula: How far does the nose piece insert into my nose?
Adjust the boom cannula arm and the nose piece so that it comfortably rests in your nose and delivers oxygen. You may be used to two sides of dual cannulas pulling the nose piece tightly into your nose but with the boom arm you will not feel that pressure and it may feel loose, but as long as the oxygen is delivered into your nose you have a good fit.
Aithre Shield: Is the read-out to the Aithre Connect App and/or Avionics instantaneous or is there a lag time?
Initial output to the Avionics and to the app takes between 30-60 seconds or sooner to output. Then the refresh is every 12 seconds or so. There is sometimes a slight discrepancy between the avionics and app output due to slightly different refresh timing. Occasionally because of rounding differences the output number can be different by 1 on the avionics and the app.
Aithre Shield eDot: What is the hole size for the panel light?
Use a 7/8" unibit type drill bit. There is a provided light plate provided to cover any imperfections in the panel hole cut.
Aithre Shield eDot: How large a space does the panel light and plate take up?
The plate is 37mm wide, 40mm tall. The hole opening is 23mm.
Illyrian III vs Illyrian II: What is the difference between the Illyrian III and the Ilyrian II?
The Illyrian III is the 3rd generation Illyrian and has a wired data output to the avionics via the HealthView III. The HealthView III supports wired connections for up to two Illyrian III, to receive and forward data to the avionics every 12 seconds for continuous output. The HealthView III can output SPO2 to Garmin, Dynon, and Advanced using analog voltage output. The HealthView III provides more data fields to the AHV avionics, including SPO2, HR and signal quality. Note that the Illyrian III dropped the head movement sensor as this sensor created production problems and was unreliable.
Part 23 Aircraft: Which systems can be installed in Part 23 Aircraft?
Most of the Aithre products can be installed in Part 23 Aircraft under the FAA NORSEE approval letters. These includes the Shield, Turbo, AVI, Metis product lines. These can be installed in any make, model, and vintage Part 23 aircraft as a logbook entry minor alteration. No 337 form is required. Reference the FAA NORSEE approval letters for additional details.
Leaking Regulator or Bottle: I have isolated my regulator and it is leaking, what should I do?
Oxygen leaking is frustrating. We test each regulator at 2000 PSI for 48 hours and use a combination of oxygen thread tape and paste to seal joints. The regulations can leak over time due to failed or stiff seals or from movement of the fittings. The best way to test for leaks is using the SHERLOCK brand gas detector fluid. It will bubble with a leak. Do not use water as water will corrode the regulator and make the problem worse. If a leak is found, it is possible to empty the tank and then remove the affected fitting. Use 2 layers of GASOILA brand oxygen thread tape, wrapped tightly opposite the direction of threads so that the tape does not bunch when screwed back into place. A small amount of LOX8 oxygen thread paste on the tape will further seal the interface. Aithre can repair and retest any unresolved leaks under warranty or for shop time of approximately 1 hr plus shipping.
Shield eDOT 5.0: Can the eDOT 5.0 also connect to the AHV?
The HealthView III includes a Shield carbon monoxide detector inside and supports the eDOT light output, RS-232 output, and analog voltage outputs to Garmin, Dynon, Advanced, and the AHV. Essentially, the HealthView III is the new eDOT and does the light interface plus the avionics integration, and still supports the Aithre Connect iOS app. There are pins on the HealthView III dedicated to connecting the eDOT light indicator. There is an additional cost of about $40 for the eDOT light indicator when adding this to the HealthView III.
Glider Systems: Which oxygen systems are best for a glider?
The AVI-G installed and AVI portable 1-place systems are the best for gliders. Due to limited power availability in gliders, the Turbo oxygen generators are not ideal due to the 80W power draw.
Formatting SD Card for AHV software update: Is there a particular format for the SD card when updating the software of the AHV?
The Micro SD card should be an 8GB-32GB formatted with FAT16 or FAT32. There should not be any other file on the Micro SD card except for the software being updated. For example, when updating the AHV-57, only put the software file for the AHV-57 on to the Micro SD card. Otherwise, the AHV-57 may not recognize the file and initiate the automatic update on its power cycle.
