The P/N 2071 Electronic Flap Actuator is an electronic module designed to automatically control an electrical flap actuator and provide visual readout of 4 flap positions. The device can be used with any electrical actuator providing the operating current is less than 8 amps at 12 volts. A 5K or 10K resistive sensor is required to provide a voltage readout of the actuator position. The control unit incorporates four pushbutton switches with built in LED lights. The system can be easily calibrated to your flap system. This involves first placing the actuator in the manual mode then manually moving the flaps to a desired position by pushing one of the switches. Once the flaps are positioned correctly, a combination of switch actions will record that flap position in the onboard memory in the actuator. This process is repeated until the values for all four positions have been stored in the memory.
Once calibrated, pushing any of the switches will activate the actuator and drive the flaps to the correct pre-defined position. When the flaps are at the correct position, the actuator will stop, and the LED in the correct switch will illuminate indicating that the flaps are in the correct position.
The LED lights in the display can be dimmed by hooking the dimmer output to an external dimming voltage. The Flap actuator also incorporates an electrical flap position interface for use with the Aircraft Components P/N 2070 Gear Position Warning System eliminating the need to install the external flap switch.
The P/N 2071 "E" Flap Actuator weighs 3 oz. and is 4 inch long by 1.25 wide by 1.5 inch deep.
