Important notices & warnings
WARNING: Alterations, additions, or repairs not performed
by the instrument manufacturer or by a person or organization
authorized by the manufacturer shall negate any warranty.
WARNING: It is the responsibility of the installer to properly
install the device on the aircraft. In case of calibration, or any
technical or functional customization of the device, the
responsibility lies with the individual who carried out such
operation.
FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY
OR DEATH.
WARNING: If this product is not used correctly, or it is
subjected to additions or alterations, the effectiveness
of this device may be considerably reduced.
WARNING: The unit isn’t waterproof. Serious damage could
occur if the unit is exposed to water or spray jets.
WARNING: The EFCX is attached directly to the flaps
actuator: the non-respect of the instructions or a damage to
the EFCX may result in unexpected movements of the flaps.
In this situation you must immediately disable the EFCX by
turning the switch in the “MANUAL” position (see chap.4.4
“Use in MANUAL mode”).

CAUTION: the EFCX must be turned off in case of start with
booster. open the corresponding breaker before starting.
warranty shall not apply for damage to the EFCX for this
reason.
NOTE: Although the EFCX 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.
CAUTION: The pilot must understand the operation of this
instrument prior to flight, and must not allow anyone to use
it without knowing the operation. Don't use this instrument
in flight until you are sure of the correct operating of the same.
CAUTION: When the installation is finished you must do a
test, prior to flight, switching on all the possible source of
electric noise and checking the properly operation of this
instrument.
CAUTION: Using this instrument over the maximum
allowable ranges can cause malfunction or wrong indications.

Transducer installation
SECTION 2
2.1 TRANSDUCER INSTALLATION
(only if using an actuator without
integrated transducer)
The installation consists in the mechanical coupling
between the flaps actuator (motor) and the transducer
(potentiometer) which allows the EFCX to know the
actual flaps position.
Example of mechanical installations actuator-transducer

Transducer installation
NOTE:
- The transducer's travel must be at least 10mm more
then the actuator's travel.
- The electrical resistance of the transducer must be
from 1 to 10 Kohm.
- The transducer must be centered over the actuator's
travel so that it isn't possible to exit from the limits, with
consequently damage to the position's transducer.

Actuator installation
2.2 ACTUATOR INSTALLATION
If the actuator doesn't have any internal limit switches
it's necessary to install them externally.
To avoid the possibility of mechanical and electrical
damage, the actuator travel must match exactly with
the flaps travel: with the actuator completely retracted
(limit switch reached) the flaps must be completely
retracted (or completely extracted for inverse
mechanical coupling); with the actuator completely
extracted the flaps must be completely extracted (or
completely retracted for inverse mechanical coupling).
Adjust your actuator travel if it does not coincide with
the flaps travel, for example using an arm/lever with an
appropriate length.
If the condition above indicated is not satisfied the
actuator is not protected against possible overtravel
during flap extension and retraction, therefore a pilot
that drive the flaps manually (for example using
“Manual” mode of the EFCX) can cause mechanical
damage if he don't stop exactly when the flaps have
reached the up and down positions.

Actuator installation
Correct installation: actuator travel exactly match flaps
travel.
IMPORTANT NOTES WHEN USING ACTUATORS
WITH INTEGRATED 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.

CAUTION: Voltage peaks higher than 15 Volt on the
supply line can damage the device.
Connector pinout:
NOTE: It’s recommendend to use shielded cable (2
poles+shield) for the motor output (pin#1 & 6),
connecting the shield of the cable to ground on the
EFCX side and leaves disconnected the shield on the
actuator side.
CAUTION: The EFCX must be turned off in case of start
with booster. Open the corresponding breaker before
starting.
NOTE: Use aeronautical standard wire and cable.

3.2 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 (for example 1N5402, which can be
purchased from us or from RS components with cod.774-3338).
Pay attention to the UP and DOWN limit switches mechanical and
electrical installation, because a wrong connection can prevent the EFCX
from turn off the actuator before the mechanical stop, with possible
damage to the actuator itself.

3.3 WIRING DIAGRAM FOR ACTUATOR WITH
INTERNAL LIMIT SWITCHES
If the actuator used has integrated limit switches and wiring
(no external wires) use the wiring diagram above, connecting
pin #1 and #6 of the EFCX connector directly to the actuator.

3.4 WIRING DIAGRAM FOR ACTUATOR WITH
INTERNAL LIMIT SWITCHES AND
EXTERNAL WIRES
If the actuator used has 3 wires for the limit switches
connection, probably one wire is the common contact for the
limit switches, so the wiring diagram to the EFCX is the following:
Wiring diagram for actuator with internal limit switches and
external wires.
Note that the common contact of the limit switches is connected
to pin #9.
