Attenuation Of Output; Power Fault Inspection While The Laser Is In Use - JUKI PS900SB13090CKZ Instruction Manual

7-4. Attenuation of output

1) Extremely high water temperature
2) If the water quality is poor, mucous membrane will adhere to the water cooling tube wall after the
equipment has been used for an extended period of time to cause a reduction in the cooling effect.
3) If the laser equipment has been operated for a long time under the condition that the maximum op-
erating current value of the laser tube is exceeded, the laser tube will be bleached.
4) Stains on the output lens
Recommended measure : ① Refer to

7-5. Power fault inspection while the laser is in use

Carry out the following inspection procedure after you have confirmed that the laser tube has no defect
in appearance.
1) In the case the laser power supply is provided with the testing function, the lamp will light up and the
laser tube will irradiate laser beam when the test switch is pressed when the laser power supply is in
the standby state. If the lamp fails to light up, the laser power supply is damaged. If the laser fails to
irradiate the laser beam even if the lamp lights up, the laser equipment is damaged.
2) In the case the laser power supply is not provided with the testing function, connect two lead wires
of the laser power supply signal ports 5V and IN. Connect three ports L, P and G and turn ON the
power to the laser equipment. If the laser equipment fails to output energy or the energy output is
inadequate, the laser equipment has been damaged. If the current is 10 mA or less, the laser power
supply has been damaged.
If any of the following troubles has occurred, contact our After-Sale Service department for appropriate
handling.
