Overview

 Here is what we are going to do, in summary:

1. De-energize the system and locate the laser power supply (LPSU)
2. Locate the green 6 pin connector/opto-board
3. Remove the green 6 pin connector/opto-board from the LPSU
4. Re-Energize the system
5. Press the red test button on the LPSU and note the value on the meter

This tool will walk you through each step, and the team is ready to assist should this diagnostic prove inconclusive. Just report back in the ticket with the issue.

We will need to gather some info to sucessfully complete this procedure.

Here is what we need to know: 

• Location and identification of the laser power supply and optoisolator board

Prep

Before attempting diagnostics or repairs on the machine, make sure you have all power switches off and have the machine power cable removed from its outlet, so the system is completely deenergized. And take before pics always.

If this test is a success, the laser beam power will be emitted. Precautions should be taken such as closing all the other machine doors and removing objects from the path of the laser beam prior to the test. Also make sure your chiller is on and pumping chilled water as this test can bypass the Water Protection as well.

LPSU Location

 All Nova series machines except Nova 24 have the LPSU mounted behind the doors on the BACK of the machine. The opto board is conected to the LPSU:

The Nova 24 LPSU is on the LEFT side. The opto board is conected to the LPSU:

Be sure to de-energize the system

Remove Optoisolator

With the system de-energized, carefully remove the green 6 pin connector and opto-isolator.

Now let's re-energize the system (the MAIN, LASER, and CHILLER switched must all be in the ON position) and press the red test button long enough to get a reading on the currennt meter.

Note that current value and report it back to the tech team in your ticket.

The diagnostic will now exit and direct you to our knowledge base. 

Please report the findings of this test in your support ticket. Thanks.
