TROUBLESHOOTING USINGTHEBALLAST’S STATUSLED
The multi-color status LED provides
information on the status of the ballast
with respect to its connection to a
controller and its general operating
condition, and also gives error and
warning signals. Consult the tables at
right to interpret the status LED.
• All operating codes are
represented by GREEN signals.
• All warning codes are
represented by RED signals.
• All history codes (except the ignition code) are represented by YELLOW signals.
• BLACK dots in the diagrams represent the unlit LED.
• Warning codes and history codes override operating mode display.
LED signals are represented by colored dots in the diagrams in the table. In the STATUS
INDICATIONS table, the green dots do not represent individual flashes; instead they
represent the duration that the LED is illuminated green. Each dot shown in both diagrams
represents one half second. For example, the “Ballast on” signal is shown as a black dot and
then four green dots. This indicates a dark (unlit) LED for one half second and then a long
green flash lasting two seconds.
In the ERROR ORWARNINGS INDICATIONS table, the individual colored dots do represent
individual flashes (black dots represent time that the LED is unlit between flashes). They also
represent the relative time duration of signals (each dot still represents one half second).
For example, the “Too high voltage”signal is shown as two red dots followed by two black
dots. This indicates two red flashes of one half second each followed by one second of
a dark (unlit) LED.
