Upon encountering alerts or alarms, sometimes the robot arm does not return to its home position.

If the consumables in the instrument are installed incorrectly or a foreign object is present in the instrument, the robot arm can collide with these objects and stop abruptly. The instrument interface displays, Collision occurred.

To fix these issues, you need to reset the robot arm.

To reset the robot arm, run the needle change workflow as described in the service tools (see Change the needle of the dilutor tool), without changing the needle.
