4.5 FC-LD (Oscillation Unit) Inspection and Replacement
If the initial laser output level cannot be restored despite adjusting the equipment and cleaning the
optics, set the LD current to 48 A (45 A for the ML-7112AH and 32 A for the ML-7064A). If this fails to
improve laser output, the LD has reached the end of its useful life and should be replaced.
Prepare to order a replacement FC-LD (Oscillation Unit) when you must increase the LD current to 45 A
(40 A for the ML-7112AH and 32 A for the ML-7064A).
■
FC-LD (Oscillation Unit) Warranty Period
When output of the FC-LD (Oscillation Unit) or diode laser declines and the specified laser output
cannot be obtained even after increasing the LD current to the maximum, the LD has reached the end
of its useful life.
The FC-LD is warranted for a period of two years from the date of acceptance inspection or shipment of
a new FC-LD. Refurbished FC-LDs are warranted for a period of one year from the date of shipment.
Replacement FC-LDs provided while under warranty are covered until the original warranty period
expires, at which point replacement of an FC-LD at the end of its useful life incurs a fee. A breakdown
of the customer cost for replacement is shown below.
Note that operating the equipment at output levels exceeding the maximum permissible level or
removing any of the adhesive seals on the FC-LD will void the warranty.
