10 TEMPERATURE PROTECTIVE DEVICES
For hazardous safety and lifetime optimization the RLX CxZ1.21 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.
11 MAINTENANCE
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
CxZ1.21 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.
12 TROUBLE 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 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 Ch. 10) or
an unintended DIM signal or connection
on the DIM connections.
Check ambient temperature
and dim control connection.
