The Altitude Motor Switch (AMS) is a versatile device suitable for several competition categories where the
altitude or motor run time shall be limited. It can be used also as a standalone telemetric variometer. The
sensor is usually connected between the receiver throttle channel and the appropriate signal input of the
electronic speed controller.
The AMS contains a sensitive barometric altimeter/variometer which uses the latest MEMS technology to
achieve a high level of accuracy, while preserving miniature dimensions. The sensor is able to detect tiny
changes in atmospheric pressure to indicate the change of altitude with resolution 0.1m. Using the integrated
high power cables you can directly power the receiver and servos through the AMS from a BEC circuit of the
speed controller.

NSTALLATION
Connect the AMS between the receiver and the electronic speed controller. To control the motor, select the
appropriate channel on the receiver. Note that the sensor is very sensitive to changes in atmospheric pressure
and also to mechanical stress. Try to avoid any mechanical stress on the sensor. To achieve the most accurate
altitude measurement, pay attention to the placement of the sensor. The device should not be exposed to direct
airflow and any close contact with heat-emitting objects (e.g. motors or speed controllers) should be avoided.
As an additional function, the telemetry output can be used for setting or wireless data reading. Connect an
extension cable with JR connectors between the telemetry port of the receiver and the "Data" port on the
sensor.
