7-2-4 Air-cooling fan
The air-cooling fan cools the laser oscillator and internal power circuit. This product has two fans (intake) on the head
and two fans (exhaust) on the controller. The fans in the head rotate at the time of laser pumping and during guide laser
radiation (except during guide pointer radiation), the controller fans rotate all the time during power on.
„
Effect from deterioration
Depending on the usage environment, any dust or contamination adhered onto the fan may impair air flow rate of the fan
or even stop the rotation of the fan. When the cool performance decreases, the temperature in the electric circuit or laser
oscillator will go up, which may cause an error or stoppage of laser radiation. Also, a temperature rise in the housing will
foster deterioration in the internal parts, which may cause the marking performance to degrade, or failure of the equipment.
„
Replacement interval
• The fan does not rotate, or the rotating speed is low.
• There is contamination on the fan that cannot be removed by cleaning.
• Abnormal noise is generated from the fan.
• Warning for stopping operation occurred.
