SPARK Flex will indicate important status information on its multi-colored Status LED visible through the frosted plastic near the USB port. The following tables shows each state and the corresponding LED color pattern.

Fault Conditions

Condition

12V Missing

The motor will not drive if powered only by USB. This blink code warns the user of this condition.

Orange/Blue Slow Blink

Sensor Fault

This can occur if the sensor type is misconfigured, the sensor cable is not plugged in or damaged, or if a sensor other than the motor sensor is plugged in.

Orange/Magenta Slow Blink

Gate Driver Fault

A fault reported by the core internal electronic circuitry. If this code persists after power cycling the controller, contact REV.

Orange/Cyan Slow Blink

CAN Fault

The CAN fault will be shown after the first time the device is plugged into the CAN port and a fault later occurs. Check your CAN wiring if you see this fault.

Orange/Yellow Slow Blink

Temperature Cutoff Fault

The motor or motor controller has gotten too hot to continue running. This fault will clear automatically after the system cools down enough to run again.

Orange/Green Slow Blink

Corrupt Firmware (recover using Recovery Mode)

Firmware failed to load.
