9. Operation
9.3 Pylon
The motor and the electronic control system are located in the pylon. They generate the
propulsion. In addition, several protective functions are integrated:
1. T
emperature 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.
2.
Under
voltage protection: If the voltage falls below 16 V, the electronic controller
switches the drive off to prevent overdischarging the batteries. Even beforehand, the
output of the motor is regulated to avoid high currents of over 120 A.

.
Blocking protection: If the propeller is blocked or stuck, the motor would normally take
in 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 unblocking, the
motor can be re-started out of the stop position after about 2 seconds.
4.
Cable damage protection:
If the steering cable is damaged, i.e. if the connection to the
tiller is cut, the motor will not start, or it stops.
5. Acceleration control:
The alteration speed at which the speed of the propeller adjusts
to a changed tiller position is limited in order to protect mechanical drive parts and to
avoid short-term peak current.
•
If the motor malfunctions, first shift the tiller handle onto the stop
position for approx. 2 seconds. The stop position has a reset function
and can correct minor faults itself.
The
Fin supports steering movements and protects the propeller when it comes into
contact with the bottom.
The sacrificial anode protects the metallic components that are located under the
water from corrosion, especially in salt water.
