General Operating Information
• The speed controller is ready for operation immediately after switching it on. If the accelerator/brake lever
is not in idle when switching on, the model will start driving immediately.
• If the speed controller detects an unusual voltage after switching on, it will emit a corresponding warning
sound (2 beeps, 1 second pause, 2 beeps, 1 second pause, etc.).
In this case, check the battery (voltage, charge) and the plug connection between the battery and speed
controller.
• If the speed controller detects an erroneous control signal from the receiver after switching on, it will emit a
corresponding warning sound (1 beep, 2 second pause, 1 beep, 2 second pause, etc.).
Check the trim of the throttle lever or leave the throttle lever in the middle position (idle position) when
switching on the speed controller.
• The red LED flashes during forwards and reverse movements or for the corresponding control signal of the
transmitter. The green LED is also on when driving forwards at 100% throttle.
If 100% brake effect is set in menu item 5, the green LED also flashes briefly.
• In drive mode 2, the accelerator lever must be in idle briefly (approx. 2 seconds) when toggling between
forward and reverse. If the throttle is shifted directly from forwards to reverse, the speed controller’s brake
will be activated (the vehicle will NOT go backwards!).
• If the drive or brake function is opposite to the movement of the throttle lever at the transmitter, activate the
reverse function at the transmitter or swap any two of the three motor cables.
Attention, important!
If the motor and speed controller are operated with the sensor cable connected (recommended
for crawler vehicles), the motor connection cables must not be interchanged. In this case, use
the reverse function of your transmitter to reverse the direction of rotation.
• The function of the fan must be checked before and after each drive. This applies in particular when the
vehicle came in contact with water. If in doubt, the fan must be dismounted and cleaned.
• The speed controller switches off the motor for safety reasons, if it gets too hot. In this case, stop driving
and check, e.g., the gear transmission and the function of the fan on the speed controller.
• If the speed controller does not detect a rotation speed signal for longer than 0.2 seconds during driving,
the motor is switched off. In this case, check the position of the receiver antenna, the connection between
speed controller and transmitter and the transmitter batteries.
Ending the operation
First switch off the control unit (bring switch into the “OFF” position). Then, disconnect the battery from the
speed controller. Only now do you turn off the transmitter.
