Several reasons for no output from the laser source

Laser source model: ALPHALAS PLDD-50M

Possible reasons for no laser output:

1. Leakage current:




The laser source is a German product, so the original three-hole plug cannot be used normally in some areas. It may be that in order to be used normally, someone may remove the ground terminal of the three-hole plug corresponding to the three-hole power cord, resulting in leakage. Maybe it is because of leakage protection, or maybe other reasons, the laser cannot work correctly.

Performance: There has been a leakage situation, that is, there is a tingling sensation when touching the laser source housing; neither continuous mode nor pulse mode can emit laser.

Solution: Replace the power cord with a standard 220V three-hole power cord in your region.

2. Trigger mode is selected as external trigger but no external trigger source

Normally, the internal trigger should be used. If the external trigger is selected by accident, the laser cannot be emitted in pulse mode.

Performance: It works normally in continuous mode and does not work in pulse mode.

Solution: Change the trigger mode to internal trigger.


3. Other conventional reasons


Such as not being self-locked internally, just refer to the manual.
