Protech PT80 Turbine Starting/Set-up problems – Projet ECU
Hi there,
I am very new to Jet turbines so just learning the ropes.Just recently I purchased a band new Protech PT80 Turbine and am having problems activating the auto start or indeed getting the turbine to start.The Protech uses a Projet Eagle ECU and Projet GSU.
Should the Turbine start with all of the default ECU parameters? (voltages/temperature settings etc?)
The instructions manual is very unclear but I have adjusted the RC timing for throttle and throttle trim to maximum/minimum and also set the fuel pump voltage to 2 volts.
I have noticed however that the default value for the maximum starter voltage is 2 volts however the GSU indicates 9 volts and when I try and change it to the default setting the starter motor becomes hot and a warning buzzer sounds.
When I switch the ECU on, the LED on the IO board become green, then when I advance the throttle and trim to maximum the LED becomes orange (ready) but then I can’t seem to engage the auto start .
Any help would be very much appreciated as I seem to be nearly there but just struggling at the last hurdle. A mentioned the Turbine and ancillaries are brand new with zero run time.
Kind Regards

Also, in function #71 "R/C Timing"... make sure the pulse increases with throttle advancement and not decrease. If it decreases, you will have to reverse the throttle channel.
The manual states that the starter voltage should be 2 volts, so not really sure why your GSU is showing 9 volts unless you accidentally missed the decimal and it's reading .9 volts

RE: Protech PT80 Turbine Starting/Set-up problems – Projet ECU
Hi there,
Many thanks for getting back to me. I have'nt had time to look into the problems any further today bit will try tomorrwo. I have tried the throttle & trim to the low position and then simultaneously moved the throttle and trim back to the high /full position but it does'nt seem to initiate the auto start.
I have checked the R/C timing and the pulse does increase with throttle advancement. I will however re-check the starter voltage.
The battery I am using is 9.6v 4600Mah 8 cell and I have adjusted the ECU to show8 cells.
Any further help in the interim would be once again very appricated.
Just one further question - Should the Turbine start using all of the defaut ECU settings?
Kind Regards

Hi there,
I am going to have another look into my problems over the weekend but I just wondered if anyone knew the following;
Should the Turbine start using all of the defaut ECU settings?

RE: Protech PT80 Turbine Starting/Set-up problems – Projet ECU
Should start with default settings. Can you check the voltage across the starting motor when auto start is engage?. Most starting motor max voltage is between 3 to 5v so 2v looks right. Can you run a motor test from your start box?
.
Ok after reading this part i'm pretty sure either your Starting motor bad(witch you can easily check by using a AA battery to test the motor it self) Or your FET driver in the ECU is blown. So you might have to send it back for repairs.
P.S My opinion

RE: Protech PT80 Turbine Starting/Set-up problems – Projet ECU
Hi there,
Thanks again for your feedback, it is very much appreciated.
I have had another go this weekend and have managed to engage the auto start from the transmitter but still no joy in starting the turbine.
When I advance the throttle and trim to max, the LED illuminates orange on the IO board indicating “ready”, then when the throttle and trim are returned to min, then back to max (within the 2 second window) the LED on the board illuminates red indicating auto start.I can hear the solenoids working but the starter motor does not spool up.The GSU reads the following over a period of around 10 seconds before returning to the “ready” state
PROP-IG STARTUP AUTO SLOW DOWN COOLDOWN
The error I then received was “No Ignition”, then the second time I tried the error was “Flame out”
The only parameters I have changed on the ECU are the battery configuration to represent 8 cells, the R/C timing and the fuel pump voltage to 2 volts.
I am still concerned with regards to the default value for the maximum starter voltage as the instruction manual states 2 volts however the GSU indicates 9 volts and when I try and change it to the default setting the starter motor becomes hot and a warning buzzer sounds.
As mentioned before the Turbine and ancillaries are brand new and unused.
basimpsn – thanks for your help, I will check the starter motor this week but if this is ok, do you know where I can send my ECU to be checked/repaired?
Any further help or advice would very much help as this problem is a little frustrating as with the complete package being new I would have expected this to be quite simple to run?
Kind Regards
Jerome

Hi there,
Following on from my previouspost I have now checked the starter motor with a direct battery connection - The starter motor works fine but I still have the problems with regards to the ECU indicating 9 volts and the auto start not initiating.
Your thoughts would be very much appreciated as I am very keen to get the turbine up and running. Please help! :0)
Kind Regards
Jerome
