TROUBLESHOOTING GUIDE
Problem
Light doesn’t turn ON
Unit is flickering
Solution
Make sure the unit is connected to the power supply and the power
supply is connected to an outlet with the correct specifications.
Make sure you are using a power supply with the correct specifications.
Make sure the unit has not overheated by operating at a room
temperature exceeding 40°C.
Make sure electrical power is available to the AC outlet being used.
Make sure the power supply has the right specifications.
Make sure the device is operating within the specified operating
temperature range. If unit overheats, it will automatically shut down.
Make sure the fan is operating properly.
Controllability
Multiple A160WE lights can be controlled by either a single
external 0~10V controller or manually.
MAINTENANCE
1. Keep the air venting holes (E), and fan clear of dust. To clean the fan, unplug the unit
and insert the tip of a CO2 dust blower (or similar dust blower) in one of the venting
holes (E) on the unit's outer shell. Hold and spray. You can also gently vacuum the
light through the venting holes.
2. Keep the lens (G) clean. If the lens becomes contaminated with water, dust, or other
particles, unplug the unit and clean the lens with isopropyl alcohol. Wet a cotton swab
or a napkin in isopropyl alcohol, gently wipe the surface of the lens, and let it dry.
CABLES
Available cables:
• Control Cable (Please consult kessil.com
for list of available cables and compatible
controllers).
• Unit Link Cable (6' male/male with 3.5 mm
stereo jack).
• Control Extension Cable (6' male/female
with 3.5 mm stereo jack).
STARTING A CHAIN
Connect two or more lights with the Kessil
Link Cable, as shown to the above.
CONTROL METHODS
There are two ways to control a chain of lights:
• With an external controller;
• Without external controller (Tuning Controls
on first light control all other lights in chain).
Should a longer cable be needed, the Kessil
Extension Link Cable may be used.
Each light has its own independent power
supply. Any number of lights can be daisy
chained together without degradation of
signal. However, in longer chains a slight
delay in response may occur. Manual tuning
is disabled when device senses input cable.
