MAINTENANCE AND TROUBLESHOOTING

PAGE

Maintenance and Troubleshooting

Use the information in this section to perform maintenance or troubleshoot your

p100/150 laser.

•

Maintenance – describes typical p100/150 maintenance procedures.

•

Troubleshooting – explains how to troubleshoot common p100/150 problems.

Important Note: This section of the Operation Manual explains how to conduct regular main-

tenance and/or basic troubleshooting to p100/150 lasers. If you cannot attend to the unit using

the information described in this manual, contact NOVANTA®, (+.425.349.3500) or an authorized

NOVANTA Distributor.

Maintenance

The Maintenance section includes subsections:

•

Disabling the p100/150 laser

•

Daily Inspections

•

Storage/shipping

•

Cleaning optical components

Disabling the p100/p150 laser

Before performing any maintenance on your

p100/150 laser, be sure to completely disable the laser by

disconnecting the DC Power Cables from the DC power supply.

Caution: Possible Equipment Damage

Inlet cooling water temperature must always be maintained above the dew point to prevent

condensation and water damage to your laser.
-Or-
Use purge gas to prevent condensation damage if the dew point is over 22°C

Do not exceed a gas purge pressure of 34.5 kPa (5 PSIDo not use argon as a purge gas.

Use only nitrogen or clean, dry air as described in the in this chapter.

Caution: Possible Equipment Damage

If you operate the laser in dirty or dusty environments, contact NOVANTA® about the risks of doing so
and precautions you can take to increase the longevity for the laser system and associated optical

components.
