Information on operation
Important!
The speed controller included in the kit is designed for operation with a 3 - 4-cell LiPo recharge-
able battery (rated voltage 11.1 - 14.8 V) or an 8 - 12-cell NiMH rechargeable battery (rated
voltage 9.6 - 14.4 V).
Connecting a battery with more cells to the speed controller will damage the speed controller
and/or motor. This will void the warranty/guarantee.
If connecting a motor to the speed controller that is suitable for more cells, always observe the
threshold values of the speed controller, see chapter "Technical Data”.
• When the speed controller is switched on, the green LED flashes according to the number of cells in
the connected LiPo battery (e.g. 3-cell LiPo-battery = flash 3x). An audible signal sounds with the same
number of signals as LED flashes. When all LEDs have gone out, the speed controller is ready to use.
• If the speed controller recognises an abnormal voltage value, the speed controller emits a corresponding
warning signal (2 tones, 1 second pause, 2 tones, 1 second pause, etc.).
In this case, check the battery (voltage, charge status) and the connections between the battery and the
speed controller.
If the speed controller recognises a faulty control signal from the receiver after being switched on, the red
LED on the speed controller flashes quickly.
• Check the trimming for the throttle lever or release the throttle lever into the centre position (neutral posi-
tion) when the speed controller is switched on.
• The red LED lights up in forwards and reverse or with the corresponding control signal from the transmitter.
When driving forwards at 100% full throttle, the green LED also lights up.
If a braking effect of 100% is set under menu item 5, the green LED lights up briefly when using the brake
or when reversing.
• When changing between forwards and reverse (in travel mode 2), the throttle lever must be placed briefly
into the neutral position (approx. 2 seconds). If the throttle lever is shifted directly from forwards to reverse,
the speed controller's brake is activated (the vehicle will NOT go backwards!)
• If the drive function or brake function respond opposite to the movement of the throttle lever on the trans-
mitter, activate the reverse function on the transmitter or swap any two of the three motor cables.
• The functionality of the fan must be checked before and after each trip. This is especially true if the vehicle
has come into contact with water. In the event of doubt, the fan must be dismantled and cleaned.
• For safety reasons, the speed controller switches the motor off in the event of an excess temperature
on the speed controller (i.e. over +105 °C). In this case, the green LED on the speed controller flashes.
Discontinue operation immediately and check the transmission of the drive and the functionality of the fan
on the speed controller.
• If the speed controller recognises that there is no signal for speed control for more than 0.2 seconds in
operation, the motor is switched off. In this case, check the position of the receiving antenna, the connec-
tion between the speed controller and the receiver and the batteries in the transmitter.
Ending operation
First, switch the speed controller off (move the switch into the "OFF" position). Then, disconnect the drive
battery (or both drive batteries) from the speed controller. Only now do you switch the transmitter off.
Disposal
Electronic devices are recyclable waste and must not be placed in household waste. Always
dispose of the product according to the relevant statutory regulations.
