Fault Messages
Fault Messages
The AX2500/2850 uses the LED display to report fault conditions. When these messages
are displayed, the motors are normally stopped.
No Control
This message is displayed in the R/C mode to indicate that no valid radio signal has been
detected at its inputs, or that radio signal has been lost. When the controller is configured
in the mixed mode, signals on channel 1 and channel 2 must be present to enable the con-
troller. When the controller is configured in the separate mode, a signal received on either
channel will enable the controller. When enabled, the controller will display the normal
motor status described previously.
