Figure 4-20 48 VDC fan connection - internal speed control. 

 

External fan speed control (ti80 only)  

On ti80SA lasers only, the side-mounted DB-9 connector also provides an external PWM output, PWM 

Control Output, on Pin 1. This output provides a 5 V PWM signal for controlling the speed of PWM-

enabled cooling fans based on the laser’s output power and chassis temperature as shown in the figure 

below. At tickle, or very low PWM duty cycles, cooling fans run at reduced speed to minimize noise; at 

higher PWM duty cycles, fan speed increases to match the cooling rate to laser power output.
