Configuration of ICW Technologies IFC-10 flap controller

The transmotec actuator extends if +ve voltage applied to its red wire -ve voltage to its black wire, and retracts if reversed.

The Sling KAI shows the right hand wing is shown, inverted:

Rotating the flap torque tube clockwise (facing the wing as seen in this picture) raises the flaps.

Such rotation occurs when the actuator extends, i.e. then the positive actuator wire is connected to +ve

From the IFC-10 manual, page 3:

Also, page 4

Contrary to the above images, a blue wire (which was verified to perform the flap-up function) was attached to pin13, while a brown (not purple) wire was attached to pin 10 (which was verified to perform the flaps down function).

So pins 10 and 13 are transposed in the diagram above

The manual does not associate the pins to the cable colours, but inspection of my cable assembly yields the following:

• pin 7,15 black: - aircraft ground
• pin 1,9 white: + aircraft power
• pin 13 blue: pilot flap up
• pin 10 brown: pilot flap down
• pin 8 white/black: airspeed
• pin 11 red: to actuator positive
• pin 12 green: to actuator negative

I have removed the following wires:

• co-pilot flap control on pins 5 and 14
• doubled actuator wires on pins 3 and 4
• doubled aircraft power wire on pin 9

From the above

Flap Actuator motor: Red #20 to Flap Motor + Green #20 to Flap Motor - NOTE: This polarity must be used to drive the flap actuator in the UP direction.   

The problem with this sentence is the only connection between red and green and particular pins is what is provided in the supplied connector, for nothing is mentioned in the manual. The above table shows what I found by inspection.

So the red (pin 11) wire of the IFC-10 should be connected to the red actuator wire, and the green (pin 12) of the IFC should be connected to the black actuator wire.

The blue wire was verified to perform the flaps up function (motor ran only when the blue wire was grounded).

The brown (not purple) wire was verified to peform the flaps down-function (motor ran for an interval after momentary grounding of the brown wire).

And the flaps up function was associated with extension of the actuator, confirming correct wiring of the latter.

The pilot flap-down-time trimpot was adjusted slightly so that three bursts on the flap down switch will provide roughly 10, 20, 30 degree flaps (assumed to be full travel of the actuator)
