Fault Messages

The AX2550 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.

The “no control” message is displayed using the following sequence of digits.
