Connection Rules
1. Always install two (2) lamps. Operating with only one lamp may overdrive lamp current at maximum brightness settings.
2. Verify lamp wiring before connecting lamps to the inverter module. Connecting both lamps to one of the two inverter output circuits will result
in reduced brightness. The LXM1620-01 module connectors are wired per industry standard. The lamphot wires (high voltage wires) are always
on pin 1 or 2, and thecold wire (low voltage wire) is always on pin 3.
F A ILSAFE FEATURE FOR MUL TIPLE LAMP O PERA TIONS
Ourmulti-outputinvertersaredesignedtokeepyourapplicationoperat-
ing at near normal brightness in the event that a lamp fails. This allows
the display to remain "on-line" until lamp replacement is convenient.
Linfinity "pairs" the lamps so that if one lamp in the pair breaks, most
of its current is added to the good lamp. CCFLs will respond with more
brightness for a period of time. Operating time in this mode will be a
functionofthelampsagebutshouldbetypicallyintheorderofhundreds
of hours.
This operating characteristic can provide adequate display perfor-
manceforalimited,butusefulperiodoftime. Shorteningofthelamplife
in this mode is typically not a concern as it is recommended thatall lamps
in a display be replaced at the same time.
