Undervoltage recognition
The battery voltage is permanently monitored. If a certain battery voltage is exceeded (threshold approx. 9.4 V), the
red LED starts to flash quickly. The green LED is permanently lit. This indicator can only be reset by disconnecting the
flight battery. If the red LED flashes, you should carry out a landing as quickly as possible and adjust the flight operation.
If the QuadroCopter is connected to a non-fully charged battery, this can also lead to undervoltage detection
and the motors do not start. In this case, fully charge the flight battery first of all and then try the take-off
once again.
If the charging end voltage of the battery is reached, the red LED „LED2" will flash at a quick rhythm. At the same time,
the signal encoder will start emitting sounds at a slow rhythm. Land at once when you notice these signals. If you
ignore these signals, the battery will be discharged further and the signal encoder will start emitting warning sounds at
a quick rhythm. If the alarm signals are still ignored the flight control will switch off the motors when the battery drops
below a specified voltage. The QuadroCopter will crash. Loss of guarantee/warranty!
Motor error
The electronic system finds an error in one or several motors. Check the connection cables of the motors for cable
breaks and good soldering to the motor driver PCBs. Ensure that the rotors are running smoothly. For this, observe the
notes in the chapters „Assembly of the Rotors" and „Maintenance, Care and Repair".
The interferences shown are usually not permanent but have been caused by temporary causes.
Disconnection of the battery generates a reset that usually eliminates the error. The cause for permanent
interferences must be found. For visual indications of the LEDs, also observe all notes described in chapter
13.
