Instruction manual JetCat-PRO engines, 1.7 - V12.01V
For the system to work correctly, the input needs to be “teached in” one time prior to be used . For “teach in” please
follow the instructions given in chapter “
Teach the ECU to the R/C System
” (page 34 step 2).
Control via Servo-PWM Signals
Single or two channel Operation?
The engine may be operated with either one or two channels from your RC receiver (throttle only or throttle and an
auxiliary channel). If single channel is selected, starting, stopping, and controlling the power is all accomplished with
just the throttle channel. If two channel operation is selected, an auxiliary channel can be used to start, stop, or
optionally control other special features of the ECU like the smoke pump and airspeed control explained later in the
manual. Most commonly, one channel is used.
How to set your ECU for single channel operation
Single channel operation can be selected automatically by not connecting the auxiliary channel cable to the receiver.
When you are in the
learn R/C
mode, it will detect the auxiliary channel is not plugged in and will automatically change
to single channel operation (auxiliary channel =
Not Used
).
To manually select one or two channel operation, follow the instructions below. This is required for changing from
single to two channel operation.
Plug in the GSU and power up the system.
Press the
Limits
key.
Using the
►
+ key, scroll through the selections until
AUX-channel func
is displayed.
There are three selections in the
AUX-channel func menu
. While pressing the
Change Value
key, use the
◄
-
or
►
+ key to scroll through these selections.
ON Turb Ctrl ON Aux channel enabled for engine control enabled.
ON Turb Ctrl OFF Aux channel enabled for speed limiter functions and/or Smoker.
Turbine control disabled. You still need to use the AUX channel for speed limiter and/or smoker
functions but the engine control will be in Single Channel Mode.
Not Used
Single Channel Mode.
Totally disable the AUX channel input for engine control, speed sensor and smoker functions. AUX
channel wire does not need to be connected to the receiver in this mode. If Not Used is selected
and you have a speed sensor, the Maximum Limit Speed is still active, limiting the maximum speed
your plane will fly. You cannot disable this safety function.
Setup failsafe mode
The ECU has the unique ability to shut-off your engine if you have a radio failure. This is accomplished by detecting
that the signal from the receiver’s throttle output is either missing or outside the values that were learned during
setup.
YOU ARE REQUIRED TO USE THE FAILSAFE!
This will not instantly shut off the engine. A timer is started when the failsafe condition occurs and the engine will
immediately go to idle. After 2 seconds (AMA requirements as of March 1, 2004) the engine will then shut off. This 2
second timer is reset back to zero anytime a non-failsafe condition is met. Your R/C signal must be broken for at least 2
continuous seconds before the engine is shut off.
The following failsafe instructions are for PCM or Spread Spectrum receivers only. (PPM Receivers
are not allowed under AMA rules.)
