4. Using a second battery, insert the battery plug into any un-used channel in
the receiver while pressing and holding the bind button on the side of the
telemetry module. This will place the telemetry module in bind mode.
5. Make sure that the LED's are flashing on all receivers and on the telemetry
module. Place the all channels (sticks and switches) on the transmitter in
the desired failsafe position. Now bind the transmitter to the system.
6. Remove the second battery from the receiver, remove the bind plug and
move the telemetry module connector to the bind port to allow flight log
data to be displayed.
Note: Do not leave the secondary battery plugged in for more than a few
minutes as damage to the battery can occur.
Failsafe Functions
The AR9110 PowerSafe features two types of failsafe: SmartSafe
and Preset Failsafe.
SmartSafe Failsafe
This type of failsafe is recommended for most types of giant-scale aircraft.
Here's how SmartSafe works.
Receiver Power Only
When the receiver only is turned on (no transmitter signal is present), all
servos except for the throttle are driven to their preset failsafe positions,
normally all control surfaces at neutral and the landing gear down. These
failsafe positions are stored in the receiver during binding. At this time the
throttle channel has no output, to avoid operating or arming an electronic
speed control (if used). In glow-powered models, the throttle servo
receives no input so it remains in its current position.
Note: Some analog servos will coast (move when powered up)
slightly even though there is no signal present. This is normal.
The receiver remains in standby mode with the blue battery LEDs lit. When
the transmitter is turned on, the receiver locates the signal (GUID), connects
and normal control resumes. When connected, the amber LEDs on all
attached remote receivers will be on.
After Connection
When the transmitter and receiver are turned on and after the receiver
connects to the transmitter and normal control of all channels occurs, if loss
of signal occurs, SmartSafe drives the throttle servo to its preset failsafe
position (low throttle) that was set during binding. All other channels hold
their last position. When the signal is regained, the system immediately
(less than 4 ms) regains control.
SmartSafe:
• Prevents unintentional electric motor response on start-up.
• Establishes low-throttle failsafe and maintains last-commanded control
surface position if the RF signal is lost. Note: Failsafe positions are stored
via the stick and switch positions on the transmitter during binding.
