4.3. Switching on the Light Source
After setting up the light source on a working surface, follow the steps below:
Figure 8 Switching on SLS201L/SLS202L
1. Connect the power supply to the 4-pin "Power In" plug on the back panel
of the light source;
2. Rotate the threaded cap on the connector to lock it;
3. Flip the toggle switch to "I" to turn on the light source.
During normal operation, the green LED on the back panel will be lit. Please allow
45 minutes warm-up time for the light source to reach a stable state. Please notice
that the cooling fan on the back panel works will only rotate after the interior of the
light source reaches 65 °C. It is completely normal for the fan not to rotate during
operations.
CAUTION: HOT SURFACE
The housing of the light source can get very hot during operation. The
temperature may reach ~60 °C. Avoid extensive contact with skin.
WARNING
The light source generates high power IR output. Do NOT look directly at the
light source beam during operation. Do NOT place hand or body part in the light
beam as this may cause burning.
