6.1.7 Pylon
The motor and
electronic control system
are located in the pylon. They generate the
propulsion. In addition, several protective functions are integrated:
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.
Under-voltage protection:
If the voltage falls below 16 V (Cruise 2.0 R) / 36 V
(Cruise 4.0 R), the electronic controller switches the drive off to prevent over-
discharging the batteries. The display shows error code E06.
3.
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 removing the blockage you can switch the motor on again. If there is a
blockage the display shows error code E05.
4.
Cable break protection:
If the connection cable is damaged, i.e. if the
connection to the remote throttle is broken the motor will not start, respectively it
will stop. An error code is shown on the display.
5.
Throttle control:
The speed at which the propeller adjusts to a changed tiller
position is limited in order to protect mechanical drive parts and to avoid short-term
peak current.
6.1.8 Changing the propeller
1. Set the main battery switch to the “off” position.
2. Loosen and unscrew the self-locking hexagon nut on the propeller.
3. Pull the propeller with the external disk from the motor shaft.
4. Pull the cylinder pin from the motor shaft and remove the internal disk from the
motor shaft.
5. Set the main battery switch to the “on” position. Allow the motor to run slowly and
check whether the shaft is turning unevenly at the shaft sealant ring. Contact
Torqeedo Service if the shaft is damaged or uneven.
6. Set the main battery switch to the “off” position. Insert the new cylinder pin
centrally to the motor shaft and insert the internal disk onto the motor shaft.
7. Place the propeller onto the motor shaft and turn the propeller until the cylinder pin
fits into the groove of the propeller.
8. Place the external disk over the motor shaft and screw the self-locking hexagon nut
onto the shaft.
