• Turn on Machine (Machine may control Chiller or House water)
• Turn on the Chiller or House water if external to machine (Ensure Flow to both Laser and beam delivery optics)
• Turn on 24V Auxiliary Supply to Laser Control
• Turn on Diode Power Supply
• Starting the Operation
• Set ENABLE High
• Laser Ready O/P High
• Set POWER SET High (0.5 to 10V = 5% to 100% Power)
• Set MODULATE High
• EMITTING O/P High (Laser emission status indicator now amber)
• Laser now delivering Output Power as requested.
• Shutting Down the Operation
• Set Modulate to Low
• Set Power Set to 0V
• Set Enable to Low
• Turn off Diode PSU (allow PSU to discharge)
• For a Full Shut Down State
• Turn Off 24V Auxiliary supply for control
