LED Status Light - using it as a diagnostic tool:
The LED is provided as standard to give users a continuous visual feedback of the functional status of the actuator.
• If the LED is not lit the actuator is not receiving, or seeing external power at the grey DIN (power) plug.
• If the LED is solidly lit, the actuator has power applied and is/ should be ready to respond to remote commands.
• If a problem exists and the actuator does not respond to remote commands, the sequence and colour of the blinking gives an indication of the possible cause.
