Troubleshooting

Indication: No ORANGE Status LEDs on power up.
Problem: Input power issue or joystick trim tab off center.
Possible Solutions:
1. Disconnect CAN cable(s).
2. If Status LEDs remains off, check +V or GND connections for voltage and proper polarity.
3. If Status LEDs blink ORANGE, the speed controller is probably damaged. The final test to
determine if the Falcon 500 / Talon FX is damaged is to replace it with another Falcon 500 /
Talon FX that is known to function properly.
Indication: Flashing ORANGE Status LEDs on power up.
Problem: No CAN/PWM signal.
Possible Solutions:
1. Ensure the transmitter and receiver are powered ON.
2. The CAN/PWM cable may be improperly connected. Check wire color-coding at each end. Check
that the connector is not offset by a pin at the receiver end.
3. If using PWM, check for a good PWM signal by connecting a known good servo to the PWM
cable. If the servo does not move, this can indicate either:
a. A faulty microcontroller
b. An improperly connected cable
c. A bad PWM cable
NOTE: The servo requires that voltage be present on the center pin of the PWM cable. This
connection is not required for the TalonFX.
Indication: Flashing RED Status LEDs after calibration.
Problem: Calibration Failed.
Possible Solutions:
CAUTION: PRIOR TO REPLACING A POTENTIALLY DAMAGED FALCON
500 / TALON FX, ENSURE THAT THE WIRES CONNECTED TO THE
OUTPUT ARE NOT SHORTED AND THE INPUT IS NOT REVERSED. ALSO,
VERIFY THAT THE POWER LEADS OF THE TALON FX ARE NOT SHORTED
TO THE CHASSIS OF THE ROBOT.
