Switches and Indicators
2.5. Switches and Indicators
The SLXXXX-P16 is easily controlled using the three switches located on the front panel. The Power switch applies
AC power to the entire unit when set to the | position. The “POWER ON” indicator will illuminate when power is
applied.
The “Tune Enable” keypad enables the resonant scanner housed in the swept source laser. The “Tune On”
indicator will illuminate when the scanner is enabled. The scanner must always be enabled for the unit to function
as a swept source laser; otherwise the output will be a fixed wavelength – typically 1050nm or 1325nm. Pressing
the “Tune Enable” keypad when the scanner is already enabled will turn the scanner and indicator off.
The “Laser Enable” keypad enables the laser output. The “Laser On” indicator will illuminate whenever the laser is
enabled. Pressing the “Laser Enable” keypad when the laser is already enabled will turn the laser and indicator off.
The “SYS OK” indicator will turn on when all necessary conditions are met for proper operation of the unit. The
laser cannot be enabled until the “SYS OK” indicator turns on.
The “TEMP” indicator will turn on under the following conditions: The internal temperature of the enclosure exceeds
approximately 60 degrees C, the heatsink temperature of the laser driver exceeds a maximum temperature, or the
TEC system has not attained its set operating temperature – as would be the case when first turning on a cold unit.
If the laser is enabled and a temperature alarm causes the “TEMP” indicator to turn on, the laser will automatically
shutdown, as will the scanner and internal TEC system. Once the unit returns to a normal operating temperature
the TEC system will automatically restart. The scanner and laser must be manually re-enabled.
