NOTICE
Risk of damage due to freezing
If the laser is in a cold area or one at risk of freezing
temperatures, freezing water can damage the laser
and the water lines.
ð
If you do not intend to use the laser for a pro-
longed period of time, follow the steps listed in
the section on decommissioning and disposal.
ð
When switching off the laser briefly, leave the
main switch ON. Make certain that the cooling
water supply to the laser is ensured. The tem-
perature-controlled cooling water protects the
device from damage due to cold.
After completing the work (production operation), switch off the laser
according to the following procedure:
9.
Turn the key switch on the front side of the laser to OFF.
10.
Switch off the laser with the main switch.
11.
Switch off the external laser chiller.
Overheating of the laser power supply
Once the main switch of the laser is switched on, all
laser power supply models equipped with a yellow
front are supplied with voltage, even if the key
switch of the laser is in the OFF position. The con-
stant power consumption produces heat that must
be dissipated via an external cooling system.
ð
To prevent overheating of the laser power sup-
ply, do not switch off the external laser chiller
as long as the laser is switched on at the main
switch.
