LightLas 532 – Operator's Manual Rev. No 01 Page 28 of 115
When setting up the laser unit for the operation, the correct type of Laser Delivery
Unit must be connected along with the Delivery Key that accompanies it. If no
Delivery Key is inserted then the warning message “Delivery Key Not Found” on the
LCD screen panel and system will wait for correction or reinserted before normal
console operation resume.
The Delivery Key is also an additional safety feature that prevents unauthorized use
of the laser unit. It is attached to the fiber for each of the LDU’s to eliminate any risk
of inserting the wrong Delivery Key. It is an essential requirement in order to ensure
that the correct calibrated power level is delivered to the patient.
The following paragraphs describe the actual operation of the system
The system consists of two major parts: the console and the LCD touch control panel
integrated with computer platform
Inside the Laser Console there are several operating components that put together
to provide the output Laser beam such as:
Laser Diode (808nm)
Laser Cavity and optics system
Thermal Electric Coolers and Driver units
Electronic Microprocessor control system
Power supply
First of all, main source power must be connected to the laser console system before
the system is enabled to function accordingly. Secondly, a blue LED backlight power
switch, located at the bottom of the screen (refer to fig. 4.3), on the LCD control
panel display needed to be enabled and wait for system software to boot up before
proceed to the next procedure (refer to fig. 4.1 - 4.2). Once the software is properly
boot up, then the key-switch is inserted and turned to the ON position (with the
Emergency switch in the out or OFF position). And then the console system
microprocessor controller will perform some internal checks to verify that the
machine is functioning as it should be. Few warning messages such as, "BBF
Temperature Not Ready", "LBO Temperature Not Ready" ...etc. will display on the
LCD when the console power is ‘ON’. This process usually takes less than few
seconds. If the temperature setting up process time is out of specification (> 5mins),
there will be an error code shown on the LCD display (for more detailed refer to
troubleshooting section of this manual).
