5.2 CLEANING PROCEDURE

5.2.1 CRITERIA FOR CLEANING THE FIBER OPTIC END-FACE _________________________________

Regularly check the fiber connector for dust, dirt, or damage before you connect to any external optic. 

The use of a dirty, orimproperly cleaned, fiber connector can lead to serious damage to the laser .

5.2.2 RECOMMENDED CLEANING SUPPLIES __________________________________________________

The following materials are recommended for fiber connector cleaning:• Powder free rubber gloves or finger cots

  • Lint free optical cleaning wipes and/or swabs• Acetone (optical grade, water free)
  • Compressedair (oil free, water free)• Microscope (IPG model or equivalent)• Light Source

5.2.3 CLEANING INSTRUCTIONS______________________________________________________________

Perform the following procedure to clean the fiber connector:

  1. Beforecleaning the fiber connector, all electrical power must be removed.
  2. Leave protective cap on and cleanthe fiber connector exterior with optical cleaner, wipe it with a clean optical wipe and dry with compressed air.
  3. Place fiber connectorin the holder of the microscope.
  4. Place pressureon the center of the securing arm before tightening the locking screw, as shown in .
  5. Place the cap face down on a clean surface.
  1. Focus the microscope onto the connector surface.
  2. Use light source to illuminate the face of the connector so that the light is reflected from the surface of the microscope. This is achieved if you see a bright golden shine from the IPG (yellow cable) connector end-face or ablue surface for the connector.
  1. Inspect the surfacecarefully. Any contamination might lead to dark spots on the surface and eventual fiber failure. If contamination is visible on the quartz block, continue to the next step. Proceed to Step 14 if there is no contamination visible.
  2. Try to blow away the dust withcompressed air from the side.
  1. While wearing powder free gloves, fold the lint free optical wipe into halves until it is roughly 1×1½” rectangle).Put a few drops of optical cleaner onto the lint free optical cleaning wipe on the folded edge of the wipe as indicated.
  1. Re-inspect the lens.
  2. Repeatstep 10 with Acetone if lens is still contaminated.
  3. Ifnecessary, put a drop of Acetone onto a cleaning swab and gently wipe away contamination in a circular motion being careful not to scratch the lens. Then repeat from Step 10.
  1. Repeat above cleaning steps until all contamination is removed. This cleaning procedure can be stopped at any time if a good result has already been achieved. After fiber connector is clean, use compressed air to clean the protective sleeve and install onto the connector.
  1. If the fiber is not to be connected immediately with a suitable optical component, use compressed air to clean the protection cap and install it over the fiber end.

TROUBLESHOOTING

6.1 | Introduction
6.2 | Error Conditions

6.1 INTRODUCTION

The device consist of two sub-systems, the laser module and the chassis.

  • Thelaser module includes the communication interface and controller which provides all the monitors and status bits reported through the computer interface and webpage.
  • Thechassis consists of the housekeeping and laser power supplies and the interlock controls. The status of the chassis can only be determined through  the front panel LED status indicators (power on/off, emissions on/off, error) and rear panel remote control options via computer interface (25pin male  connector), RS232 (9-pin male connector) or Ethernet connection.

 There is no direct communication between the laser module and the chassis. While the laser module receives powerfrom the chassis, troubleshooting requires  interrupting the status reported from the laser module through the computer interface (25-pin connector) and the chassis front panel indicators.

The chassis front panel LED status indicators provide the first level of operational information.

  • POWER and EMISSION: When these indicators are on (lit), the chassis has provided power to the laser module and the laser module is signaling that emission is on.
  • ERROR:When this indicator is on (lit), there is an error either from the laser module or the chassis. The error can be determined by using the computer  interface to read the status through the serial commands or webpage, IPG IG337 Web User Utility.
