CONVENTIONS USED IN THIS MANUAL
Within the text, logic signals that are active low (“notted”) will appear inside of slash marks, as illustrated below.
/ATTENIN/
These signals are “active”, or true, when the logic level is low. When the logic signal /ATTENIN/ is low, the attenuator loop is “OK” (complete). When the logic signal /ATTENIN/ is high, the attenuator loop is not OK (open). In most of the schematic diagrams such signals are indicated by the usual solid line above the signal name, as illustrated below.
ATTENIN
The schematics in this manual do not include individual numbers for the logic elements or operational amplifiers within a single component. For example, U1 which is illustrated on the next page, contains two

INTRODUCTION
WARNING: Installation by untrained persons is a potential hazard to the persons doing the installations, others present, and to the equipment itself. In addition, improper installation is a potential hazard to the user, persons present during use, and patient.
These installation instructions are provided for use by Lumenis Service Engineers who have completed certification service training on the VersaPulse® PowerSuite™ laser. Installation by untrained persons is a potential hazard to the person or persons performing the installation, others present and to the equipment itself. In addition, improper installation is a potential hazard to the user, persons present during use and patient.
2.1.1 1.
Site Inspection
Check for proper site set up. This includes proper AC service and adequate space for the console.
AC power configuration: The VersaPulse PowerSuite requires 220 VAC±10%, 50/60 Hz, 30 Amps (32 Amps for 100W Holmium) single phase electrical service. The power cord is a 26 ft. cable with two conductors and a ground. An AC Control PCB behind the right side cover allows for tapping of the isolation transformer to the setting closest to the incoming electrical service. The system can be hard wired to the electrical service or installed to the electrical service with a plug and receptacle. Customers are responsible for supplying electrical connections (i.e., electrical receptacle and mating plug).
Console dimensions and weight: The console measures 36” L x 18” W x 39” H. It weighs approximately 350 lbs. A minimum of 18” of air space is required around the unit to provide adequate cooling air circulation.
The system requires approximately 2.5 gallons of distilled water for its closed loop cooling system. The coolant must be added as described in this procedure.
Complete specifications for the VersaPulse PowerSuite laser are included later in this section and in the VersaPulse PowerSuite laser Operator Manual. Contact Technical Support in Santa Clara, CA. if there are any questions concerning site preparation.

Unpack & Inspect Laser
Check the crate/carton for any shipping damage.
The shipper is responsible for any damage to the system in shipment. If the crate/carton appears to be damaged, report the damage to the customer and shipper.
2.
Remove the console and accessories from the crate (refer to Fig. 2.1).
a. Loosen the six butterfly clamps securing the side door and lower the side door (the side door is used as a ramp to remove the console from the crate). Remove the protective foam and accessories box. Install the ramps onto the base, then roll the unit down the ramps.
b. Return all packing material to the crate and save for future use.

3.
Move the system to its installation location.
The VersaPulse PowerSuite laser rolls best when pushed from the front handles. The front wheels swivel, the rear wheels do not.
4.
Open/remove covers and do a visual inspection of the interior.
Refer to Section 5 for information on removing the covers. Open the front cover, then remove the top and two side covers. Inspect the interior carefully for loose or broken electrical or optical connections, loose or broken plumbing connections, or any indication of shipping damage.
2.1.3
Configure AC Control PCB
Refer to Section 3.3.1 for additional details.
1.
AC voltage configuration preparation.
a. Measure the mains voltage and record.

b. Verify the VersaPulse PowerSuite is not connected to the AC mains.
2.
Locate the AC Control PCB (behind the right side panel) and identify TB5 & TB2 (top of the PCB). Refer to Fig. 2.2.

Locate the large brown wire in TB5-1 and position the other end in TB2 as follows:
a. For mains voltage in 190 - 210 VAC range, connect TB5-1 to TB2-2.
b. For mains voltage in 211 - 230 VAC range, connect TB5-1 to TB2-3.
c. For mains voltage in 231 - 264 VAC range, connect TB5-1 to TB2-4.
4.
Locate the two small blue jumper wires in TB7 (bottom right). Position the jumpers as follows:
a. For mains voltage in 190 - 210 VAC range, jumper TB7: 1-3, 4-6.
b. For mains voltage in 211 - 230 VAC range, jumper TB7: 1-3, 5-6.
,167$//$7,21
9HUVD3XOVH3RZHU6XLWH6HULHV6HUYLFH0DQXDO 5(9%
c. For mains voltage in 231-264 VAC range, jumper TB7: 2-3, 5-6.
5.
Record the voltage range on the Certification Report.
6.
Connect to AC service.
CAUTION: Once connected to the site electrical service, lethal voltages are present inside the unit. The AC power is present at the circuit breaker, main contactor and the AC Control PCB. Review and understand the safety subtopic in Section 5 before proceeding.
The system can be hard wired to electrical service, but is more typically connected by a plug to an electrical outlet.
If the system is to be hard wired, the customer must provide an electrician to wire the cord end into the electrical service outlet. A lockable electrical service disconnect switch must be installed if the system is hard wired.
If the system is to be plugged into an electrical receptacle, the appropriate receptacle should already be installed by the customer’s electrician. The installing engineer connects the plug to the end of the VersaPulse PowerSuite electrical cable.
2.1.4
Add Coolant
Add coolant (distilled water) to the fill reservoir. The coolant will drain out of the fill reservoir and into the main reservoir. The system uses approximately 2.5 gallons of coolant. Most coolant can be added at this time - until the fill reservoir level stays up. The system coolant level will be “topped off” after the system is turned on (in a later step).
NOTE: Use distilled water only! Do not use alcohol or glycol based additives.
2.1.5
Turn On
CAUTION:
• Once the circuit breaker is turned on and power is applied to the VersaPulse PowerSuite laser, wait a few minutes and observe for any indication of failure of the mains or turn-on components. Check for any coolant leaks.
9HUVD3XOVH3RZHU6XLWH6HULHV6HUYLFH0DQXDO 5(9%
,167$//$7,21
• The system will fire during the turn-on sequence regardless if SW3 (Autocal) on the CPU PCB is left or right and the BRH plug is installed. Only those persons required should be present during this portion of the installation - those present must wear appropriate laser safety eyewear and follow all laser safety precautions.
• The cooling fan blades are not covered. The fan is located on top of the heat exchanger. It operates whenever the system is turned on. Keep tools, system parts and body parts clear of the fan blades.
1.
Turn and hold the keyswitch to the START position, then after approximately two seconds, release it to the ON position. The system will go through its start up sequence. Observe for normal start up, and for any indication of leaks in the cooling system.
2.
Add additional coolant if necessary.
NOTE: Only add water if disconnected from AC mains.
Turn system off and disconnect from the AC mains. Top off the fill reservoir. Reconnect to AC mains and cycle the machine off and on several times, adding coolant as necessary until the fill reservoir level stays up to approximately half full as the system runs.
3.
Perform Fiber Alignment Test, Verify Calibration procedure and the Operational & Safety checks in Section 3.
4.
Replace all covers and prepare the system for demonstration to the customer.
2.1.6
Customer Demonstration
1.
Demonstrate the system operation to the customer.
2.
Fill out and mail the “self mailer” installation quality audit report (for U.S. Field Service).
3.
Fill out the System Certification report.
