JETS MUNT S.L
Electronic Control Unit (ECU)
The ECU integrated inside the engine is custom designed for the VT80 engine and must not
be changed for any other, as this may result in improper control of the engine. Your engine
has been set up and run with this ECU at the factory and the settings should be left as
default. The ECU plugs into your receiver throttle channel and is powered from the receiver
rechargeable battery. The ECU is pre-programmed and only requires simply setting to your
radio.
Smart Data terminal
The Smart Data terminal plugs into the ECU via the
lead supplied. The display can be installed permanently
on board. This socket also doubles as digital connection
to a computer.
The Smart Data terminal includes dedicated screens for
radio checking, last shutdown cause and other special
turbine operations. The most innovative and useful
function is the internal recorder/playback function. The
terminal continuously stores all the data received from
the ecu, keeping in its permanent memory all the data of
last 66 minutes of engine run, without the need of the
memory card. After the flight, the terminal can be pulled
out of the plane and, without connecting to the ecu, just
using an 5-10V battery, the data stored can be played
back in real time, same presentation as if the engine was
running. Playback mode can be still, forward or reverse, speed x1, x 10 and x100 in both
directions, so that would be easy to investigate any issue at the field without the need of a
computer or any other type of reader.
Data, including all engine parameters, can be saved later to a memory card, where it can be
read using a text editor, or our viewer software. Also can be sent to engine manufacturer to
be studied, and changes uploaded back to the ecu.
Check the instructions on page 23. The function of the buttons is described later in the
“ECU setup”.
Engine installation: Electrical connections.
Connect the battery to the Multiplex socket “MPX”, connect the
throttle channel from your receiver to the socket “Throttle”, connect
the brushless pump to the socket “Pump” and the smart data terminal
to the socket “Terminal”.
PLEASE: DOUBLE CHECK THE BATTERY POLARITY BEFORE CONNECTING IT TO
THE ENGINE.
A reverse polarity connection will immediately damage the electronic components inside the
engine.
Recommended battery is a LiPo of 7,4V and at least 2000mAh /15C. Optionally is possible
to use an A123 battery of 9,9V, although the engine is happier with 7,4V. 3s Lipo is not
supported.
