Spektrum BEAST X AR7210BX Mode D'emploi page 19

N RPM Governor — Operation modes
At Menu Point N you can choose from three options:
• Deactivated — the RPM Governor is not used. All control commands on the
throttle channel will be passed to [THRO] output directly.
• Electric — select this option if your helicopter is powered by an electric motor
and an electric speed controller is plugged into [THRO] output of the Spektrum
AR7210BX. Spektrum AR7210BX reads the RPM signal from the speed controller or
a phase sensor and controls the rotor speed accordingly.
NOTICE: The ESC must not be operated in a (heli specific) Governor Mode. The
ESC must process the incomming throttle signals and control the motor as direct and
unfiltered as possible.
• Nitro — with this option, the Spektrum AR7210BX can govern the rotor RPM of a
helicopter with nitro or gas engine. For this, the Spektrum AR7210BX controls the
throttle servo which is connected to [THRO] output and that controls the carburetor
of the engine. The motor RPM will be read from a magnetic or optical sensor that
captures the RPM from the crankshaft of the motor, the clutch bell or the main gear.
Choose by moving the rudder stick in one direction until the LED indicates the desired color and state:
If the RPM Governor is
AR7210BX will exit the Setup Menu if you quickly
press the button. If you have chosen to activate
the governor, pressing the button will lead to
Governor Menu Point A.
Governor Menu
If the RPM Governor is activated at Setup Menu Point N (setting "electric" or "nitro") then you
can access the Governor Menu immediately. Here, various helicopter-specific information must be
provided, necessary for RPM Governor functionality. The transmitter will be prepared for use with the
RPM Governor function. At Menu Point A, a function test for the RPM sensor is performed.
CAUTION: Always keep a safe distance in all directions around your model to
avoid collision or injury. Pay attention to your own safety and the safety of other
people and property in your vicinity when using our product. When using helicopters with
nitro/gas engines make sure that the motor will not start when making adjustments to the
system. When using a gas engine always keep the ignition system deactivated. For electric
helicopters remove the motor pinion from the main gear during initial setup. Never touch the
motor when it's running. Always keep a save distance to all rotating parts of the helicopter.
A Function Test for RPM Sensor
In order to use the Spektrum AR7210BX Governor, the system must be able to detect the motor
speed with the help of a RPM sensor that must be attached to the sensor input of Spektrum
AR7210BX. For models with nitro/gas engines, usually sensors are used that determine the
speed signal magnetically or optically. These sensors are mounted next to the crankshaft or
clutch bell and register the number of engine revolutions here.
