A flashing Error LED during initial setup may be related to a locked output, the maximum current not yet being configured, or an active pause on the device. Check that the OUT-OFF switch is in the unlocked/on position, set the appropriate maximum current for the motor, and remove any active pause from the device.

Before changing parameters in the app, you must press the configuration edit button. This prevents unintended changes by keeping the settings read-only until edit mode is enabled. After making the required changes, press the Submit button to save the new configuration.
