2.4.12 7-Segment Display
The 7 segment LED display on the front panel shows the status of the controller in real-time. The following
table lists the front panel LED display codes and their meaning. If multiple errors are present, the display
will cycle through all the error codes, displaying each for ½ second. Most errors can be reset by either
pressing the front panel pushbutton switch or cycling power to the unit, although some errors cannot be
fixed in the field. Please contact the factor for assistance with any errors that do not clear after a reset.
