Smart-Fly PowerExpander Eq10 Technical Reference

While you are adjusting the servos the unit will automatically save your latest
change if you do not change the function or channel and do not enter a new
change for 15 seconds. The current values will be saved so you do not lose
them if you accidentally turn the unit off without changing the function or channel
selectors. Each time you move to a new function or channel the settings
for that function and channel will be saved also.

Running

This is the default position the unit should always be in when
not adjusting the servo parameters.
1 Adjust This function adjusts the centering and endpoints of servo A.
Servo A When the LED is blinking slowly, the adjustment is the sub-
trim (offset) of the servo. When the LED is blinking fast the
adjustment is one of the endpoints. Pushing the "INCR"
button will increase the travel arc and pushing the "DECR"
button will decrease the travel arc when adjusting endpoints.
If the LED stays on constantly while you are calibrating an
endpoint you have exceeded 130% of the nominal electrical
endpoint. When this happens, caution should be exercised
since some digital servos can start misbehaving at values
greater than this.
The unit works in continuous or endpoint-hold modes when
adjusting servo travel. If the endpoint-hold option is off the
unit will follow the transmitter stick travel at all times. You
need to be aware of the LED flash rate to see if you are
adjusting the sub-trim (centering) or the endpoint travel. If
the endpoint-hold option is on then the unit will have some
movement in center so it can follow the center the transmitter
is outputting. When you go to adjust an endpoint the unit will
hold the servo at the endpoint it gets from the transmitter.
When the transmitter stick is moved to one of its endpoints
and held, the unit will recognize this and move to that
endpoint. When at an endpoint and the stick is moved to the
opposite endpoint then the unit will return to center. The
rotary dial may be moved to adjust servos A, B, and C while
at an endpoint. Also, if the output priority mode is set then
when servo A is adjusted servos B, C and D will freewheel.
When servo B is being adjusted servo A is also driven and
servos C and D will freewheel. When servo C is being
adjusted servos A and B will also be driven and servo D will
freewheel. When servo D is adjusted all servos are driven.
2 Adjust Adjust the centering and endpoints of B. See description of
Servo B

"Adjust Servo A."

3 Adjust Adjust the centering and endpoints of C. See description of
Servo C "Adjust Servo A."
4 Adjust Adjust the centering and endpoints of D. See description of
# Name Description
Servo D "Adjust Servo A."
5 Reverse Reverse direction of servo A. When the servo is normal, the
Servo A LED pulse rate is slow. When the servo is reversed, the
pulse rate is fast. Pushing "INCR" reverses the servos while
pushing "DECR" returns the servo to normal. The buttons
must be pushed for approximately 1 second to make the
change. This is to prevent accidental reversal of servos.
6 Reverse Reverse direction of servo B. See description of "Reversing
Servo B Servo A".
7 Reverse Reverse direction of servo C. See description of "Reversing
Servo C Servo A".
8 Reverse Reverse direction of servo D. See description of "Reversing
Servo C Servo A".
9 No No function in this position in run mode. Used to access the
Function Option Menu with special power up sequence.

Receiver Failure or Interference Behavior

The PowerExpander Eq10 checks the validity of the servo signal coming from
the receiver. The channel LED is on continuously when a valid servo signal
comes from the receiver (transmitter must be on). If the PowerExpander Eq10
does not see a valid signal or any signal for one-half second, it turns the LED off
and either continuously sends the last good position to the servo or stops
sending a signal to the servo (see Option Menu item 3).
PowerExpander Eq10 recognizes a good signal from the receiver, the unit turns
on the LED and begins updating the servo position again. PCM receivers will
output the last good position or a programmed failsafe position when they lose
the transmitter signal. FM receivers will stop sending a signal to the servos. If
you have an FM receiver you can program the PowerExpander Eq10 to either
continuously update the servo with the last good position received or discontinue
updating altogether.
