WARNING
The LED Matrix- 3R SeaLite has thermal protection
designed into the LED light engine and the electronic
driver. If the light is operated in air for an extended
period of time the useful life the LED’s may degrade
and the external temperature of the housing will reach
temperatures that may be painful to human touch. If
the light is operated briefly for testing purposes in air,
be sure to let it cool down for a couple of minutes before
immersing it in water to minimize thermal shock to the
components. It is also a good idea to turn the light off a
few seconds prior to removing it from the water as part
of normal recovery procedures, as this will minimize
buildup of scale on the LED window and housing
components.
The LED Matrix- 3R SeaLite is made from superior
strength aluminum alloy 7075 to make it as lightweight
as possible. It has been hard anodized and fitted with
strategically placed sacrificial zinc anodes to resist
corrosion of the body. Be sure to regularly inspect these
zincs for depletion and replace them before they are
fully corroded. These lights are not designed for long
term immersion of more than several weeks. Designers
and end users must employ a system-wide corrosion
prevention scheme that includes this strong, but less
noble metal.
Pre Dive Inspection:
Ensure the connectors are tight. Occasionally twisting
of the connector occurs when unscrewing the locking
sleeve which will cause it to loosen from the body.
Should this occur, tighten the connector until you feel
the connector body engage the housing, and then ap-
ply additional light torque to fully seat. A loose connec-
tor may cause the light to flood.
1. Engage the locking sleeve and tighten to finger
tight, never use a wrench.
2. Turn on light to check operation. Turn off and let
cool before deployment.
3. Check conditions of anodes. Clean and replace
as needed.
Post Dive Inspection:
1. Rinse your LED Matrix- 3R SeaLite in fresh water
after every dive.
2. Check conditions of anodes. Clean and replace
as needed.
3. Wipe sapphire port with a soft clean towel
4. Occasionally remove the crash guard and inspect
for signs of corrosion or biofouling.
5. Grease threads of 316SS screws with
AquaShield Lubricant for improved corrosion
resistance.
Troubleshooting and
Maintenance:
Problems and Causes
There are three main elements of your LED Matrix-3R
SeaLite to consider when a problem is detected.
1. Power connector and cable
2. Driver and interface board, including the fuse
3. Remote light heads and their respective cables
and connectors
If your LED Matrix-3R SeaLite is not operational, make
certain power is being delivered to the mating connector
on the appropriate pins. If power is being supplied
please follow the table below for troubleshooting
procedures.
