Page 53 Fire the laser. (For Holmium wavelength) Test the output at all combinations of low, medium, and high pulse energies and repetition rates. The delivered power must be within ±10% of indicated (requested) power. (For Neodymium Wavelength) Test the output in continuous exposure mode and at low, medium and high average powers. The delivered power must be within ±10% of indicated (requested) power.
Page 54 Each individual laser must reach the 20% line by its second shot. If any of the laser cavities do not, the alignment of that particular cavity may need peaking. Also, check the mode burns at this point. Note that even if the burn may look good, the cavity may need peaking. NOTE: It is permitted for the first shot of each cavity to fall below 20% line on the graph.

Page 58 PERIODIC MAINTENANCE REQUIREMENT The systems require the following periodic maintenance: ANNUALLY (AS REQUIRED): Perform a general visual inspection of the electrical, mechanical, and optical components. Check/clean the air filter. The air filter is mounted on the bottom of the system, held in place by a removable bracket.
Page 59 5 to 50 Hz. The combination of pulse energy and pulse rate define an operating point. Not all combinations of pulse energy and pulse rate are valid, and the operating points available vary with the different VersaPulse PowerSuite models available. Consult the Operator Manual for detailed information on the operating points for a particular model.
Page 60 Each rod delivers every fourth pulse. This sequential firing allows the VersaPulse Powersuite to provide four times the pulse rate as could be provided by a single rod, increasing the maximum average power available by the same factor (four).
Page 61 The use of multiple heads results in a number of advantages over previous surgical solid state lasers: VersaPulse PowerSuite is smaller and lighter; it has a much simpler and more reliable cooling system; and it can operate at much higher pulse rates, resulting in higher average powers. Also, different rods and optics can be installed enabling a multiwavelength laser is one package.
Page 62 Low Energy (LE) Attenuator - The LE attenuator is inserted into the beam path to allow the VersaPulse PowerSuite to deliver a lower range of pulse energies. This function is currently used on the VersaPulse PowerSuite dual wavelength lasers (if Holmium energy is less than 0.5J or Neodymium power less than 25 W is selected).
Page 63 Service Attenuator - The service attenuator is inserted into the beam path to attenuate the beam before it enters the fiber focus assembly. This prevents damage to the attached fiber alignment detector as the system is fired to do the fiber focus alignment. It is operated by SW4 on the Controller PCB inside the unit accessible to the service engineer.
Page 64 Input Power The VersaPulse PowerSuite operates off of 200, 208 or 230 VAC ±10% @ 30A (32A for 100W Holmium) 50/60 Hz line voltage. The main circuit breaker is rated at 32 amps for 200, 208 or 230 VAC operation. The mains are wired into the circuit breaker.
Page 65 4.2.4 Turn On The following sections describe the sequence of events starting from the time the system circuit breaker is turned on to the completion of the self-test routine after the keyswitch is set to the run position. 4.2.4.1 Circuit Breaker On, Keyswitch Off The 24 VAC Interlock Transformer T2 is energized and supplies 24 VAC through F10, R13 and LED2, turning on LED2.
Page 66 4.2.5 Shutdown Under normal circumstances, the system remains on until one of the following events occur: • Keyswitch moved to OFF position • Emergency Off button pressed • Turn off or trip of main circuit breaker • Blown F6, F8, F9 or F10 fuses •...
Page 67 COOLING Refer to the Coolant System Simplified Diagram (Fig 4.1). As the lamps in the laser head are flashed, heat energy is produced in the flash lamps, rods, and housings. The cooling system transfers the heat energy from the flash lamp, rod and housings to the outside air. It utilizes a closed loop, forced air heat exchanger which contains approximately 2.5 gallons of distilled water.
Page 68 Refer to 8-12 in Section 8. Coolant resistivity and temperature are monitored by sensors that report an analog voltage to the microprocessor ADC circuit. The software checks the coolant resistivity and temperature at regular intervals in the following manner: • The coolant is nonconductive (deionized) to minimize galvanic corrosion and high voltage arcing in the cooling loop.
Page 69 Coolant flow is monitored by a flowswitch as a part of the CPU hold circuit to the main contactor. If flow is not sufficient, the system will not latch on and if already started it will shut off. The coolant pump operates continuously and at a constant speed from turn on to turn off. It circulates the coolant through the closed loop.
Page 70 4.3.1 Components Motor and Pump Head: A 1/4 hp induction motor is used to drive the pump head. The motor is thermally protected as well as fused on the mains transformer, T1 secondary. Refer to the Interlock schematic for details. The pump head is a positive displacement, graphite vane pump.
Page 71 Cavity/Manifold: After passing through the water particle filter, the coolant make its way to the laser manifold where it enters the cavity. The cavity which mounts to the manifold contains a YAG rod and a flashlamp, both contained in a glass-like material surrounded by barium sulfate powder (highly reflective). The cooling water flows in direct contact with the YAG rod and flashlamp outer surfaces to remove the heat.
Page 72 Fiber and Blast Shield Position Sense Circuits - Monitors the position of the fiber and blast shield. Described in subtopic 4.4.9. Service Attenuator Circuits - Operates and monitors the position of the service attenuator. Monitors the condition of the service and diagnostic push-buttons located on the CPU PCB. Described in sub- topic 4.4.10.
Page 73 At power up, U56 outputs /RESET/ and /HALT/ signals to the microprocessor - the microprocessor does not execute the software instructions when both lines are low. Pressing the Reset Switch SW5 provides the same reset when the system is already on. After approximately 200ms, these lines goes high, the microprocessor begins to execute the software instructions stored in the EPROM U63.
Page 74 The EPLD inputs and outputs are programmable and in the VersaPulse PowerSuite is used to serve in multiple functions in the system due to the flexibility of this chip. The Digital Input/Output EPLD U49 serves as an 8- channel digital I/O for the microprocessor.
Page 75 4.4.2.2 D/A & A/D Conversion Circuits Refer to page 8-12 in Section 8. U30 and U31 are six channel multiplexer/A-to-D converters. Each multiplexer reads their prospective analog DC voltages and convert it to digital signals. This allows the microprocessor to read the digital values which represents an analog voltage after it has received the READ/ WRITE signal.
Page 76 The Multifunction Programmable Timer (U47) outputs a variable frequency SPKR signal when the various states have been satisfied to the System Audio Amp U2. The output of the circuit is connected to an external speaker which emits a tone. The speaker volume can be adjusted by adjusting R8. 4.4.3 Shutter/Footswitch/Remote Interlock Circuits Refer to pages 8-9 thru 8-10 and 8-14 thru 8-16 in Section 8.
Page 77 The interlock loop is part of the digital I/O loop and is sensed by the microprocessor. If the CDRH Interlock was to become disconnected the ground path for the /CDRHRAW/ signal opens and the signal goes high. This signal is asserted to the input of U41 pin 13 causing the CDRHBUF signal to go low. The low CDRHBUF signal is asserted to the input (pin 17) of the Digital Input/Output EPLD U49 which the microprocessor reads, then displays a fault on the LCD display.
Page 78 motor controller tracks position by monitoring the channel A and B lines from the position sensor to determine the sum of the movement away from this known index position. SERVO_INDEX_BIT = high when pointed at plano #1. 4.4.5 HVPS & Control Circuits The HVPS and Control Circuits oversee the control and turn-on of the flashlamps, monitor the voltage on the capacitor bank, and monitor several status signals from the high voltage power supply.
Page 79 Refer to the Energy Monitor Circuits Simplified Diagram (Figure 4.5) and to the associated schematics in Section 8. The VersaPulse PowerSuite measures the energy of each YAG pulse. Two separate channels measure the energy. These two channels are required to provide safety redundancy.
Page 80 The remainder of this subtopic describes the MAIN_ENERGY circuitry and optics. The SAFETY_ENERGY circuit operates in the same manner. A sample ( 0.2%) of each YAG pulse is deflected from the first surface of the first (synthetic) sapphire wedge optic to an imaging mirror.
Page 81 The contacts 3 to 2 and 14 to 15 of U17 closes. Closing these contacts resets the main zero correction and the integrator. Closing the contacts 14 to 15 discharges C25 and C149 to reset the integrator circuit. • U9 in the safety energy detection channel. The contacts 3 to 2 and 14 to 15 of U9 closes.
Page 82 Aiming beam intensity is controlled by variable (digi-pot) resistance U3 on the Controller PCB connected to the aiming beam module through J13-3 and J13-4. The microprocessor sets the aiming beam intensity to high, low, or medium by changing the variable resistance (U3) using the /LASER_DIODE_STEP/ and / LASER_DIODE_DIR/ digital I/O EPLD output lines.
Page 83 I/O EPLD on the Controller PCB. 4.4.11 Low Energy Attenuator Circuit The Low Energy Attenuator Circuit inserts attenuation into the beam path to allow the VersaPulse PowerSuite to provide treatment pulse energies lower than the minimum pulse energy available out of the cavity.
Page 84 FLASHLAMP POWER CIRCUITS Refer to the IGBT Driver PCB schematic page 8-19 in Section 8, and the HVPS & Control Circuits Simplified Block Diagram in topic 4.4.5. Flashlamps are used as the exciter (pump) mechanism for the lasers. The flashlamps are a gas discharge device designed to produce intense pulsed radiation (visible, IR and UV) flashes.
Page 85 The Simmer/start board operates off of B+ supplied by the HVPS. Charging the Capacitor bank - For the VersaPulse PowerSuite laser, the capacitor bank charges to 800 VDC. The circuit is monitored by the Frequency to Voltage converter (U13) and is read by the main Analog to digital converter U31 as V-F_FEEDBACK signal.

Page 113 After power up, and before the VersaPulse PowerSuite laser moves to its standby condition, the software performs a series of self tests. Self test failures result in fault codes or error messages displayed on the LCD color touchscreen display.
Page 114 The VersaPulse PowerSuite laser has a series of service software routines available to the service engineer. The routines are contained in the software EPROM, and are activated by moving a switch on the Controller PCB (not accessible to the user). These routines facilitate calibration and troubleshooting. The routines are described in detail later in this section.
Page 115 The YAG laser light and its reflections are potential hazards to the eye. Use extreme caution when operating the system with the covers opened or removed. The covers contain the beam and reflections safely within the console. Only those persons required should be present during servicing and eye protection that safely attenuates the YAG wavelength should be worn by all those present.

Page 150 REMOVE/REPLACE PROCEDURE This section provide procedures in the removing and replacement of major components in the VersaPulse PowerSuite laser. Prior to removing/replacing any components in the system, the covers must be opened or removed (i.e., side covers). Refer to Section 5.2 for the removal of any of the covers. Be sure all ESD protocols are observed when removing/replacing any electronic component.
Page 151 This step MUST BE PERFORMED to prevent contamination from being dragged and depos- ited inside the cavity flow tube. d. Carefully slide the flashlamp out of the cavity assembly in the direction of the black wire. Take caution to locate the O-rings. Note the position of the O-ring on the black end of the old flashlamp.
Page 152 Remove the five nuts securing the Controller PCB to the standoffs and remove the Controller PCB. Install the new Controller PCB and secure it in place using the five nuts that was just removed. CAUTION: Be sure ESD protocols are observed when handling the new Controller PCB, otherwise severe damage to the Controller PCB may occur.

Page 157 f. Check lamp calibration values. (Higher lamp energies or cal points means more energy must be dumped into the lamps creating more heat.) If all of the above items are checked and found to be normal yet, the laser still overheats, it may be pos- sible that the water pump head is worn and not moving the water quickly enough or there may be some flow restriction.
Page 158 If the blastshield glass was known to be new or clean at the time, the optical alignment checks out to be normal, the fiber was new and was being properly used, yet the system continues to consume blastshields at a high rate, check for contamination on the fiber focus lens. To check the fiber focus lens, remove the fiber focus assembly from the laser, then remove the lens cell by first removing the beam combiner.
