Hello forum.
I have a question regarding HFS-3
How can i get data log of 0 to 5 Volt?

FIA2 Aquamist has a purple wire with voltage signal 0-100%

Second question:
Can i get 30 pin scheme (each pin purpose)
Are there any useful pins for data logging and data graph (i marked these pins with green on the photo)?

Here are some useful pins for data logging:

#5 ........... System start-up: 12V = system on.
#6 ........... Flow sensor signal: 0.5 to 4.5V
#7 ........... Water level sensor: 0v= empty, 5v= not empty
#8 ........... Fuel injector (-). not direct injection.
#16 ......... IDC% signal: 0 to 5V
#17 ......... MPS signal: 0 to 5V (signal conditioned)
#18 ......... IDC% to the water injection valve
#23 ......... System power: 12V (switched/fused)

Thank you very much!
You could describe these pins in manual, so that would bring more customers

Those pins are not static-protected so I rather use them as intended for remote diagnostic usage. They exist for the benefit for us and customer without working knowledge of our system but equipped with a simple $10 digital voltmeter.

It has been extremely useful since it was introduced.

For more knowledgeable users, all they need to do is ask here.

Interesting 11s log. Are you able to log the water flow now?

Only HFS4 has AUXFS.

What is the blue wire and the green wire that there is a manual in your?
Where do I hook up my black wire?

This option is for HFS4 only.

1. You can connect the Black wire to the blue wire of the green harness.
2. Upon the EGT voltage exceeds the AUXFX trimmer setting, it can either turn on the Water tank level led (W) or trip the failsafe to drop boost (F). You can do both at the same time if you solder link them.

Can you post the Voltage vs EGT Temperature chart here?

Where exactly is it?
In your circuit in the picture does not have a blue wire.
Draw a diagram.

2. Upon the EGT voltage exceeds the AUXFX trimmer setting, it can either turn on the Water tank level led (W) or trip the failsafe to drop boost (F).

In any case, connect the jumper, I disable the boost controller.
I understand you correctly?

there are 6 wires in the green harness: Not shown on the drawing.

1. red ............. DI (+)
2. green .......... DI (-)
3. blue ............ Aux Failsafe
4. Yellow ......... Flow sensor signal (analogue)
5. White .......... Flow sensor raw pulses
6. Black .......... Signal ground

Here is a diagram:

EGT ........... 800C = ~2.6V (just above mid point on the AUXFS trimmer.

Just looked at the PLX-EGT sendor module , very set up. I will recommend this in the future. thanks for the link.

Do you mean they are reliable?

Do you have a HFS3 or HFS4?

The white wire of the green harness is not amongst the test points.

On the last page but one of the user manual, all pin out from the controller is described.

How many channles on new model AUX? If there are 3 ( IAT EGT A/F) of them, then how to control them? There is only one AUXFX trimmer. Should be 3 too?

Richard L
22-04-2014, 07:24 PM
These is only one but can be used for anyone of named sensors. IAT is inverted.

Here are some useful pins for data logging:

#6 ........... Flow sensor signal: 0.5 to 4.5V

Is this also true for the hfs4?

Would this be 0.5v = 0% flow and 4.5v = 100% flow?
And I think more importantly can units for flow be better calculated by a procedure similar to finding the max flow during set up. Something like:
-remove jet from intake.
-Set unit to test. Collect fluid for set time (10, 30, or 60 seconds).
-Measure amount of liquid and log voltage on pun 6.
-create new voltage vs flow map .becomes .5v = '0 units of measured liquid per duration of test' (ex. 0cc/minute) and the voltage measured during the test is now equal to 'amount of liquid'/'duration of test time' (ex. 500cc/minute)

Does that seem sane? Or is the max flow at 4.5v in an amount/time unit already known?

Thanks!

Wich pin should I use to log when WI is triggered??

#30 .......... system status (signal level). 0v =off 3V=standby 8V=triggered.

I can only log 0-5v source. Any alternative? I just want to log when WI starts.

Regards.

Richard L

When you can log 0-5V, 8V will be read as 5V (clipping by your logger)

Your log will look as:
0, 3V and 5V.

Richard L

I don't quite see the point of data logging the status of the aquamist, the data is pretty static, once triggered. It woild be more useful to log the water flow (via the yellow wire of the user port). It is a 0-5 signal.
