System Status Indicators 

A multi-color System Status indicator ring LED is located on the front panel soft power switch. The System 
Status Indicator LED has 3 possible states in normal operation: 

 

Yellow, solid:  Indicates the system is in Warm-Up mode 

 

Green, solid: 

Indicates the system is in Idle or Run mode, ready to be operated and produce 
laser emission 

 

Red, solid: 

Indicates the system is has a fault 

Other indications are utilized for factory service modes. If the Status Indicator LED displays a color or blink 
rate other than described above, contact 89 North.

Laser Ready Indicators 

As shown in  Figure 4, the front  panel of the LDI  includes  two Laser Ready Indicators. These indicators 
illuminate  blue  when  laser  emission through  the  corresponding  aperture  can occur.  Both  Laser  Ready 
Indicators will remain extinguished while the system is in Warm Up mode since laser emission is prevented 
in this mode. Once the system has completed warm up, the Laser Ready Indicator will illuminate blue for 
any aperture which is capable of producing laser emission and has a fiber installed. 

       WARNING:

 

Laser Ready Indicators will illuminate blue whenever the corresponding aperture is 
capable of producing laser emission.
