 When an error occurs, observe the blinking sequence: the number of fast blinks will indicate the actuator number. \\
-Bear in mind that, in case more than one actuator has an Error Condition, the blinking sequence will include the error numbers for all affected actuators. A longer OFF period separates the blinking sequences of affected Actuators.

-This diagnostic is performed by analyzing a number fo parameters during the operation of the actuator which are then normalized into a **"Health Index"** value.
-You can check the Health Index of the actuator by issuing the ''did'' command on any console.
-A healthy actuator has a Health Index of 100. The lower the number, the closer the actuator is to its EOL. When it goes below 10, the actuator is triggers the nest error (Purple).
-Bear in mind that this number is calculated dynamically after every power on. External factors such as high temperatures or longer run times may lower the Health Index momentarily but after a reboot the Health Index may become higher. This normal and is a result of this dynamic analysis. The worst observed value over time, should the one to use as reference.
 This error condition is merely INFORMATIONAL and will not affect the operation of the actuator: the actuator will continue to respond to torque, position, etc. commands normally.

 When an actuator is in this condition, it is likely still functional but has degraded to a point where it is operating outside the set and acceptable parameters for the system.
-In this case, the actuator needs to be replaced. If encounter this condition, we recommend contacting our Technical Services (support@seedrobotics.com) and we'll gladly assist you with the procedure to get your unit in top working condition once again.
