PYLON
The pylon is the lower motor unit that contains
the motor and the electronic control system
which generate the propulsion. Several
protective functions are programmed into the
pylon.
Protective Functions
1. Temperature protection: If the motor
overheats, the motor control system reduces
the output of the drive until a temperature
equilibrium is established between generated
and disposed heat. Above a critical temperature
the motor stops and the display shows error
code E02 or E08.
2. Blocking protection: If the propeller is blocked
or stuck, the motor would normally consume
too much power. In this case, the motor is
switched off within a few hundredths of a second
to protect the electronics, motor winding, and
propeller. After removing the blockage you can
switch the motor on again. If there is a blockage
the display shows error code E05.
3. Cable break protection: If the connection
cable is damaged, i.e., if the connection to the
remote throttle, battery or motor is broken, the
motor will stop or not start. An error code starting
with E3 and containing another number is shown
on the display.
4. Location sensor: The Ultralight has an
integrated protective device that switches the
motor off when it is beyond a particular slope
(90°). This prevents the propeller from turning if
the boat capsizes or tilts further.
5. Throttle control: The propeller rev change
responds slowly to protect mechanical drive
components and avoid short-term power peaks.
6. Fin: The fin supports steering movements
and protects the propeller from hitting obstacles
underwater.
