Operation of the Electronic Ballast
3.1 Luminaire Operation
•
Lamp Starting
When the is unit powered, the lamp should strike
within 1-2 minutes.
3.2 Dimming
The Enduratron luminaires can be dimmed to
50% power with the application of a 0-10Vdc
dimming signal applied to the dimming terminals
on the top of the luminaire. If no dimming signal
is connected to the dimming terminals, the
luminaires will operate continuously at 100%
power.
The dimming operation of electronic ballast is
suspended for the first 20 minutes of operation of
the luminaire. The lamp will operate at 100%
power during this period. This delay is required to
stabilize the lamp thermally to permit good color
control and lamp stability thru life as prescribed
by the lamp manufactures.
