The model name, unique 4- or 5- digit serial number and certification markings of the light engine are carried
on a label affixed to the rear panel. Performance specifications for individual light engines are listed on the
certificate of conformance included with the shipping documents e-mailed to the customer (Figure 1).
3.2 Installation
When setting the SPECTRA III (L) light engine up for use, place the unit on a hard surface and avoid blocking
or restricting airflow at the air inlets (front panel; Figure 3) or exhaust ports (rear panel) on the enclosure.
Restricting the airflow will cause the unit to operate at elevated temperatures and will result in decreased
product life and/or premature failure. The SPECTRA III (L) light engine must be operated in a non-
condensing environment (dew point <10ºC with controlled ambient temperature <30º C). Thermal overload
protection is provided by the onboard microprocessor in conjunction with an onboard temperature sensor. If
the internal temperature registered by the sensor exceeds 50°C
OR
the fan rotor is stopped, all light output
channels automatically turn OFF and are locked in this state until the internal temperature is below 50°C and/
or the fan restarts. The current reading of the onboard temperature sensor is displayed on the front panel
status display (Figure 3) and in the Control GUI
(Section 3.3.3).
3.3 Operation
3.3.1 Controls and Interlocks
The
Master Power Switch
button on the front
panel (Figure 3) turns the electrical power to the
unit on or off. A green power indicator
embedded in the button is lit when the power
supply is connected to the light engine and the
power button is in the on position. Initialization
of the onboard computer takes about 30
seconds after the master power switch is turned
on. When initialization is complete, the status
indicator display (Figure 3) will activate.
The
Key Control
(Figure 3) must be in the on
position before light output can be turned on.
The key must be removed and stored in a
secure location when the product is not in use.
ONLY
trained individuals should use and have
access to the key. The
Master Power Switch
button,
Key control
and
Remote interlock
can be used to shut off light output.
