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 n reduced brightness. The LXM1621-xx module connectors are wired per ndustry standard. The amp
hot
wires (high voltage wires)
are always on pin 1 or 2, and the
cold
wire (low voltage wire) is always on pin 3 or 4.
FAILSAFE FEATURE FOR MULTIPLE LAMP OPERATIONS
Our multi-output inverters are designed to keep your application
operating 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 function of the lamps age but should be typically
in the order of hundreds of hours.
This operating characteristic can provide adequate display
performance for a limited, but useful period of time. Shortening
of the lamp life in this mode is typically not a concern as it is
recommended that all lamps in a display be replaced at the same
time.
