Reverse polarity protection     b. Over current protection     c. Voltage spike suppression     d. over current drain protection against mechanical failure of the actuator system *
	** The unit has an inbuilt time limit for the on time of the actuator fixed at approximately 2.5 minutes. This is to ensure that if the actuator fails to move the panel to the required target angle for more than 2.5 minutes, the unit turns off the actuator load to preserve battery life and indicates “mech failure” for 3 seconds on the LCD display before skipping to the next target angle.
