5.1 OVERVIEW
5.1.1 Service Philosophy
The VersaPulse® PowerSuite™ laser is designed to require little adjustment or calibration, and to detect and
report hardware malfunctions by fault code or error message, displayed on the LCD color display. In most
cases field failures are repaired by changing out a Field Replaceable Unit (FRU). FRU's are built specifically to
support field repair, and consist of a part or group of parts determined to be suitable for field replacement.
When a part fails that is a part of a FRU, normally the FRU is replaced, not the individual part.
Corrective and preventive maintenance must only be accomplished by a Service Engineer who has completed
Lumenis certification service training on the VersaPulse PowerSuite laser.
Field calibration and adjustment is covered in detail in Section 3. Special purpose tools are required to
maintain the VersaPulse PowerSuite laser. These tools are listed in Section 6.
The entire optical path is enclosed inside the laser head. Removing the dust cover exposes the interior to
foreign matter (i.e. dust, contaminants and etc.). Minimize this exposure by removing the cover only when
necessary, using a clear plastic cover over the head while the dust cover is off, and getting the dust cover back
on as soon as maintenance inside the head is complete.
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. These fault codes provide an indication of what malfunction was detected, which
should point to a specific area of the system for further investigation. Explanations of the fault codes are
included in this section. Most hardware malfunctions will be detected at this time.
During normal operation the software continues to monitor for system malfunctions, and to report any
detected malfunctions by fault code or error message at the LCD color touchscreen display.
Some fault codes are "logged" in a special service screen.
