Status LED Flashing Patterns
Status LED Flashing Patterns
After the controller is powered on, the Power LED will tun 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.
