TROUBLESHOOTING

Important Note: To prevent streaking during the final alcohol cleaning, drag the lens wipe slowly
across the surface so that the cleaning liquid evaporates right behind the wipe.
If acetone is used as a cleaning solvent, a second follow-up cleaning of the optical surface using
alcohol is required.

Introduction
The Troubleshooting section is designed to help isolate problems to the module level only. Problems on
circuit boards or the laser tube are outside the scope of this guide because they are not user-serviceable
assemblies; do not attempt to repair them. Contact NOVANTA or a NOVANTA Authorized Distributor
for repair information.
To troubleshoot vi30/40 lasers, it is necessary to understand the sequence of events that must happen
before the laser can operate. Before attempting any service, we advise you to read the entire
troubleshooting guide and review both the operational flowchart and the functional block diagram.
Attempting repair of a NOVANTA laser without the express authorization of NOVANTA, will void the
product warranty.
If troubleshooting or service assistance is required, please contact NOVANTA Customer Service.
Status LEDs
Three status LEDs on the rear of the OEM vi30 laser provide a visual indication of operating status. A
green PWR LED illuminates when DC power is applied to the laser. The yellow RDY LED indicates that a
Laser Enable signal has been applied and that, after a five-second delay, lasing will begin once a PWM
Command signal is received. The LASE LED illuminates red to indicate that the PWM signal is sufficient
to induce laser output. See the following pages.
