Status LED Flashing Patterns
After the controller is powered on, the Power LED will turn on, indicating that the controller is On. The Status LED
will be flashing at a 2 seconds interval. The flashing pattern provides operating or exception status information.
Additional status information may be obtained by monitoring the controller with the PC utility.
