Section 6 SERVICE PROCEDURES—PANEL REMOVAL
Removing the Dress Panels
This section of the technical guide details how to remove the dress panels for accessing and
servicing internal components.
For most common service procedures, such as accessing the control electronics or laser
resonator, it is only necessary to remove the side rails and raise the top cover. The resonator is
located under the top plate that is secured to the laser chassis.
Exercise care when removing any of the dress panels. Handle all painted items carefully to avoid
scratching or damaging them. Always store panels away from work area until service is
complete.
WARNING: Even when the laser is off and the AC line cord is disconnected, DC
voltages on various laser components, such as capacitors may exist. This can present a
potentially fatal electrical hazard during service procedures. Proceed with caution!
Take the following precautions to avoid an electrical shock during servicing:
♦
Always turn the laser off and disconnect the AC line cord from the receptacle before
removing the protective housing of the laser system.
♦
With the laser off, allow the dump resistors to dissipate the energy in the pulse forming
network’s capacitors to a safe level (approximately 45 seconds). Monitor the voltage on
the capacitors with a DVM probe to ensure it is at a safe level.
♦
If it is necessary to test or adjust any electrical component while the system power is on,
be careful not to touch any electrical components. Use only appropriate probes or
insulated tools.
♦
Become familiar with the electrical schematics and layout of the system before
attempting to service the laser.
If the AC must be connected during service routines, exercise caution around mains connected
components, such as power supply feeds, circuit breakers, key switches, etc. A remote interlock
fault condition will reduce high voltage electrical hazards. This fault condition disables the high
voltage power supply control and simmer circuits, as well as ensuring that the dump relay is
closed (grounding the potential of the pulse forming network). When possible, remove the
remote interlock plug during “live” service routines.
Removing the Top Cover
1. Disconnect the AC line cord from the receptacle.
2. Remove the four screws that attach the top cover to the top of the laser chassis.
NOTE: Two screws are located behind the front door and two screws are located on the
rear panel of the laser.
3. Carefully lift the cover off the top of the laser.
