Failsafe
The AR9140T, AR12310T and AR20310T PowerSafe receivers features two
types of failsafe: SmartSafe™ and Preset Failsafe.
Failsafe position is set during binding. In the unlikely event that the radio link
is lost during use, the receiver will drive all channels to its pre-programmed
failsafe position.
Pre-Connect Failsafe - Receiver Power Only
If the receiver is powered on, but there is no transmitter signal present
(transmitter powered off), there will be no output pulses to the servos. 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 Preset Failsafe drives all servos to their preset failsafe positions. For
SmartSafe + Hold Last
If loss of signal occurs, SmartSafe™ technology moves the throttle channel to its
preset failsafe position (low throttle) that was set during binding. All other channels
hold their last position. When the receiver detects a signal from the transmitter, normal
aircraft operation resumes.
Tip: Use either the built in BIND button OR a bind blug in the BIND/BATT port.
