EMPERATURE PROTECTIVE DEVICES
For hazardous safety and lifetime optimization the RLX DxZ1.21 LED floodlight is equipped with several
temperature protective devices. Two individual temperature controls may have influence on the use of the
floodlight.
Automated Temperature Control
A set of temperature sensors are distributed on the LED circuit board to
protect the LED and material lifetime in high ambient temperatures. This
circuit will automatically adjust the LED current as the temperature rises. It
is important to note that this circuit will not have influence on the light
output before the temperature reaches material limits. See table.
Manual Resettable Temperature Protection
The floodlight is equipped with a manual resettable temperature protective device, which will trigger and
turn off the lamp if it is heated with an external heat source or if another fatal error occurs. For the
protective device to reset, the power input must be turned OFF and ON and the temperature must be
decreased.

AINTENANCE
The product is made to be maintenance free and only occasional cleaning without solvent is recommend to
ensure light output and cooling.
Do not paint. Material combination and surface treatment has been carefully selected to make the RLX
DxZ1.21 floodlight withstand corrosive environments even with damage to the surface treatment. The
assembled unit complies with ISO9223/12944 and has a rated c5m corrosion class.
Damages to seals, gasket, breather drain, cable glands, entries, front glass, housing or terminals may
invalidate the certificate. In uncertain cases, please contact Luminell for clarification.

ROUBLE SHOOTING
Problem
Possible reason
Possible solution
Does not turn on.
The floodlight may be exposed to
external heat, causing the
temperature protection to activate.
Remove external heat source and
disconnect and reconnect power.
See section 10 Temperature
protective devices.
Turns off
automatically.
A combination of high ambient
temperature and reduced airflow
may cause the floodlight to heat up
and turn off.
Disconnect and check for
sufficient air flow.
Seems to have
reduced light
output.
High ambient temperature see
section 10 or an unintended DIM
signal or connection on the DIM
connections.
Check ambient temperature and
dim control connection.
