1. Safety Information
Thank you for choosing Raycus Fiber Delivered Direct Diode laser. This
User Guide providesimportant safety, operation, warranty and other
information. Please read it carefully beforeyou use this product. In order
to ensure safe operation and optimal performance of the product,please
follow the warnings, cautions, operating procedures and other instructions
accordingly.
1.1 Symbols Used in this User Guide
WARNING: Describes a hazard that lead to a personal injury or death.
CAUTION: Describes a hazard that lead to a minor personal injury
orproduct damage.
1.2 Laser Classification
This series of lasers are classified as a high power Class 4 laser
instrument according to theEuropean Community standards EN 60825-1, clause
9. This product emits invisible laserradiation at or around a wavelength
of 915 nm, and the total light power radiated from theoptical output is
greater than 100W. Direct or indirect exposureof this level of light
intensity may cause damage to the eye or skin. Despite the radiation
beinginvisible, the beam may cause irreversible damage to the retina and/or
cornea. Appropriate andapproved laser safety eyewear must be worn all the
time while the laser is operational.

be performed byRaycus personnel or person authorized by Raycus. Make
sure the environment is clean, orthe output head may be contaminated.
It is prohibited to use fan during installation, whichwill cause dust
in the air;
e） Prevent the delivery cable from treading, pinching or excessive
bending during installation.
CAUTION: All the cables can only be connected when power supply is
off.Hot plug may damage the laser.
CAUTION:Ensure that there are no fiber bends with radius less than 20cm
when theproduct is installed. Avoid excessive twisting and tight bends
during therobotic arm movements. Tight bends will damage the laser
deliverysystem.
When the product is in storage, the bending radius of the delivery
cableshould be more than 20cm.
CAUTION: Avoid vibration and impact to output head, or it may bedamaged.
CAUTION:Make sure the aperture and the cavity of the processing head
is clean;
Keep the protective cap properly, prevent it from contamination; Or
theaperture will be contaminated when capped.

3.4 Control Modes
There are two different modes of operation:external AD mode and RS232
mode.
The following diagram shows the process of entering a certain control
mode.

Figure 6: The Process of Entering Different Control Modes
3.4.1 AD Mode
AD mode is a remote control mode.There are two working modes in AD Mode:CW
mode and pulse mode.
The output power is set by analog signal,and pulse mode is available
in this control mode.
3.4.1.1 CW mode
In this mode, the laser emissionis continuous, so just one parameter
needs to be set-AD signalaccording tooutput power.
Wiring in AD Mode

3.4.1.2 Pulse mode
In this mode, the laser emissionis under modulation, sosetparameters
including Ext_MOD, EXT_Laser_ENand EXT_AD to switch onlaser emission.When
the parameters are set, laser emission is enabled, and the remote modulation
signal inputs from EXT_MOD, the laser emits.
Pulse mode wave diagram
Figure 9: Pulse mode wave
3.4.2 RS232 Mode
RS-232 mode is a remote control mode. In this mode, we have a protocol
for communicationbetween the laser and the upper computer, and you can set
emission parameters and getinformation from the laser.

Wiring in RS-232 Mode
Figure 10: Wiring Diagram in RS-232 Mode
There are three working modes in RS-232Mode:CW mode,modulation mode and
preset mode.
Six groups of laser power can be set in CW mode.
Six groups of parameters including laser power,frequency and duty cycle
can be set in modulation mode.
Six groups of parameters devided into 16 segments including laser power
and time can be set in preset mode.
