5.20 Flap System Wiring
The VP-X controls the aps and provides circuitry for the ap position sensor.
The aps can be congured to run either:
1. Momentary – aps only run when the ap switch is pressed. A
position sensor is optional.
2. Position – aps run down to the next position when the ap switch
is pressed. Flaps run all the way up when the ap switch is pressed.
A ap position sensor (Ray Allen POS-12) is required for this option.
You can set 4 positions – a top, two middle (optional), and a bottom.
When you press the ap up switch, the aps go all the way up unless
you press the ap down switch to stop them mid-stream. On some
aircraft, you can set the reex position to the top position, the 0 deg
position to the rst stop, approach aps to the second stop, and
landing aps to the bottom stop.
If you are setting the ap circuit breaker value to greater than
5 amps, you must have a VP-X with serial number 1350
or higher – Contact Vertical Power Support if you need an
upgrade.
As of rmware version 1.5 the VP-X also supports RV-10 reex settings. In
order to use the reex settings you must have the aps in Position mode as
described above. No special wiring is required to use the reex features. See
“10.5 Trim and ap operation” on page 68 for details on reex operation.

You can wire a ap switch for the pilot and, optionally, one for the co-pilot.
The ap switch must be an SPDT momentary action switch (ON)-OFF-
(ON), with a middle OFF position. Many ap switches also come as DPDT
switches. If you have a DPDT switch, you can wire it as shown in the diagram
below:

Only three terminals on one side of the switch need to be used.

Do not install a ap switch that stays in the UP position.
The ap switch has three pins: a common, one to command aps up and one
to command aps down.

Both ap motor pins on the VP-X (J12, pins 5 & 6) are wired directly to the
ap motor. The polarity of the wires does not matter, as it can be reversed in
the setup menus.
RV ap system: Do not install the Van’s Flap Positioning System (FPS).
If you want intermediate stops or ap position feedback on the EFIS, install a
Ray Allen POS-12 position sensor.

You can purchase a clevis/pushrod kit from your local hobby shop, as the
Ray Allen kit is not for use with the POS-12.
