7-2-9 Internal shutter
The internal shutter is opened and closed by the rotary solenoid to shut off the path of laser beam.
„ Effect from deterioration
When the rotation torque of the rotary solenoid declines, the opening/closing speed of the internal shutter is decreased
or the shutter may not work. In this case, an error "Internal shutter failure" occurs in the laser welding machine and lasing
operation cannot be performed.
„ Replacement interval
• Total number of opening/closing operations has exceeded two million.
• Alarm for internal shutter error occurred.
„ How to confirm the number of opening/closing operations
Click "Environ." on the right menu and click "System info".
The total number of the shutter operation is displayed on the screen.

7-2-10 Battery inside the controller
A lithium primary battery is contained inside the controller as battery for clock or calendar of the laser welding machine.
Based on this internal clock, the date and time information for the saving data and error log is updated.
„ Effect from deterioration
When the battery inside the controller runs out due to aging, the date and time of the internal clock may be out of
synchronization when the laser welding machine is turned OFF. If you start the laser welding machine in such a condition,
the warning for internal clock (E251) may occur and the date and time setting is required. The warning is temporarily
released by resetting the date and time, however, once the power supply of the laser welding machine is turned to off, the
warning will reoccur or the internal clock will show the wrong time.
„ Replacement interval
• Warning for internal clock (E251) occurred.
• Almost five years have passed since delivery.
