Hardware installation

Thus the Headspeed Governor of AR7210BX can be used, the system must be able to detect the motor speed. This is done with the help of a speed sensor that is plugged to the port AX2/RPM on the AR7210BX (the AUX2 output becomes an input when enabling the Governor!). 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. For electric motors the motor speed can be determined electronically. For this purpose a phase sensor (e.g. BXA76013) is connected to one or two of the motor phases. Some electric speed controllers also offer a direct signal output for the rpm signal, so that no additional sensor is required.

To see how the sensor is mounted in detail please refer to the instruction manual from the sensor or from the helicopter. The speed sensor plugged to the port AX2/RPM on the AR7210BX which also powers the sensor with the supply voltage, if necessary. Note that the height of the supply voltage corresponds to your receiver power supply voltage!

Here are some installation and connection examples. As described virtually all kinds of rpm sensors may be used. Unfortunately it is impossible to try and enumerate all types. If in doubt about whether a particular sensor can be used in conjunction with AR7210BX ask your dealer to find out.
