E-Lite 12KN -C Installation & Adjustment Instructions - page 4
To determine how many chokes
are on a given power supply,
count the number of large bolts on
the bottom of the power supply.
TO ATTACH LAMP:
Lamp is connected to the Power Supply using
the twist lock connector provided. To attach
connector, align guide rib in plastic cap with
the slot on the base, slide out sleeve toward
Power Supply and twist clockwise. To
remove, push outer sleeve toward Power
Supply and twist counter clockwise
Sunlight (UV) and ambient temperature affect the
electrical characteristics of FLATLITE. Output voltage will
vary depending on these factors. Thus setting your output
voltage during the day will cause the lamp to have a different
voltage at night. Since most outdoor FLATLITE applications
are meant for a nighttime operation, it is strongly
recommended that the power supply be adjusted at
night.
(Please note: the safety of the system is not
compromised due to the compensating features of the power
supplies.)
If night time adjustment is not possible, we have
provided a chart of equivalents. This chart shows what
output voltage to set the power supply to under a variety of
conditions. For example, if 260VAC is the desired night time setting, if it is
being adjusted during a sunny, clear day at an ambient temperature of 60
o
F
(16
o
C), it must be adjusted to 75VAC. Because the voltages in the chart are
only approximate settings, it is strongly recommended that the final tuning of the
system be performed during normal system operation times.
A lamp voltage of 280VAC is the maximum allowable nighttime
setting, which in turn yields the optimum balance between maximum
brightness and lamp life. However many nighttime applications require less
brightness to achieve the desired effect as FLATLITE Lamp is a field source of
light, rather than a point source of light. There are many variables which effect
the perceived brightness of the FLATLITE Lamp in outdoor installations,
including the ambient lighting from other buildings, streetlights, etc. Further,
when lowering the lamp brightness, the life of the lamp is extended. For best
results adjust the lamp after full darkness, taking care not to exceed 280Vac.
