3. control the flaps simply use the U D switch press and hold in a position UP or DOWN and release when the motor have reached the desired position 2 3 Troubleshooting and error code of the EFC P All the four LEDs flashing no positions programming have been made see paragraph 2 2 LED1 and LED2 flashing it means that the EFC P try to move the motor but there is no feedback from the transducer can be a wrong connections on the motor s wiring or on the transducer s wiring To exit from this condition you must turn off the device and remove the cause of failure LED1 and LED3 flashing it means that the connection motor transducer are not correct maybe the motor s wire reversal or a wrong tranducer wiring To exit from this condition you must turn off the device and remove the cause of failure LED2 and LED4 flashing it means that the EFC P has detected an over current condition Check that wirings of the actuator motor have no short circuits or check that the actuator is working correctly 3 Technical specifications Frontpanel dimensions 61 8 x 71 8 mm rectangular panel version 60 0 x 60 0 mm 2 1 4 round panel version Depth 46 mm rectangular panel version 52 mm 2 1 4 round panel version Weight 125 g Power requirements 12 20 V 80 mA Maximum current supplied to the motor 7 Ampere Operating temperature range 20 70 C Relative humidity 10 90 This product is warranted to be free fr
4. that the flaps go up If directions are reversed swap the two actuators wire pin 1 and 6 on the EFC P connector 2 The wiring between the transducer and the EFC P connector pins 3 5 depends on the actuator transducer mechanical coupling i e flaps down gt transducer s shaft extracted or flaps down gt transducer s shaft retracted To check if the wirings are ok measure the voltage between ground pin 7 and pin 4 of the EFC P connector with the flaps completely down the voltage must be to its maximum value with the flaps completely up the voltage must be to its minimum If this doesn t occur or if the EFC P does not work correctly swap the two wires on pins 3 and 5 of the EFC P connector Operation instructions 2 1 Panel indicators and commands A M switch Auto Manual U D switch Up Down The Auto Manual switch has a safety lock to avoid accidental operation it must first pulled on the outside and then moved to the desired position 2 2 Operation instructions The EFC P can work in two modes Automatic or Manual For normal operations use the Automatic mode the Manual mode must be used only in case of emergency or failure of the EFC P Before using the device for the first time you must program the four position that the EFC P store in memory and use in Automatic mode With the device powered off turn the A M switch in the Automatic position then press
5. the four LED will simultaneously flash 2 2 1 Use in AUTOMATIC mode In AUTOMATIC mode you can move the flaps choosing one of the four stored position the maximum travel of the motor is defined by the two limit switches UP and DOWN The LEDs show the status of the flaps LED on indicate the current position of the flaps LED flashing indicate the position that the flaps are reaching EXAMPLE OF USE The flaps are in the first position LED1 on all other LEDs off to move the flaps in the third position press two times the U D switch in the DOWN position the flaps start moving and the third LED is flashing indicating the position that the flaps are reaching When the flaps reaches the second position the first LED turn off while the second turn on when they reaches the third position the second LED turn off and the third turn on The flaps have reached the selected position and the EFC P return to steady state waiting for another command Pressing the U D switch in the UP position for more than 1 second move automatically the flaps to the first position regardless of the current position 2 2 2 Use in MANUAL mode In this mode the flaps position are not fixed between the four programmed positions but the movement are continuous however it s recommended to use the MANUAL mode only in case of device s electronic failure because this mode bypass the internal electronic circuits and connect directly the motor to the U D switch To
6. CONN NO CO Installation 1 1 Important notices and warnings Although the EFC P has been heavily tested to ensure the maximum safety in every condition the correct operation depends also by installation and wiring that must be accurately made and verified reading completely this manual Use aeronautic cable for the wiring and shielded cable for the position s transducer wiring The cable shielding is more effective if both termination are connected to GND The EFC P cables especially the position s transducer cables must not run near cables and power devices that could generate noise for example transponder transceiver strobo light inductive load such as electric motors electric pumps and solenoids When the cabling is finished you must do a test prior to flight turning on all the possible source of electric noise and verifying the properly operating of the EFC P The pilot must understand the operation of this device prior to flight and must not allow anyone to use it without knowing the operation Keep this manual in the aircraft WARNING The EFC P is attached directly to the flaps actuator the non respect of the notices above or a damage to the EFC P may result in unexpected movements of the flaps In this situation you must immediately disable the EFC P by turning the switch in the MANUAL position see par 2 2 2 Use in MANUAL mode THE EFC P MUST BE TURNED OFF IN CA
7. D TRANSDUCER The electrical resistance of the transducer must be from 1 to 10 Kohm Choose a model that use the maximum electrical resistance range For example if you choose an actuator with 10 Kohm transducer verify that the stroke that you are going to use provide at least a variation of half the transducer s resistance i e 5 Kohm 1 5 Electrical installation In the backpanel there is a 10 poles plug connector model MOLEX Mini Fit JR the corresponding socket connector is delivered with your EFC P The connections are ooo a sjale Socket view from wire insertion side Backpanel plug 1 Motor out 2 Power input 12V 3 Positive voltage 5V for the position s transducer 4 Position s transducer signal 5 Ground for the position s transducer 6 Motor out 7 Power input GND 8 DOWN limit switch 9 Limit switches common connection 10 UP limit switch 1 5 1 Wiring diagram for actuator with no internal limit switches If the actuator used has no internal limit switches you must install them externally and follow the wiring diagram below The UP and DOWN switches must be normally closed diodes max current must be at least 3 Ampere Pay attention to the UP and DOWN limit switches mechanical and electrical installation because a wrong connection can prevent the EFC P from turn off the actuator before the mechanical stop with possible damage to the actuator itself ONLY
