| 3 | == Instructions |
| 4 | 1. Open a browser an enter the IP address of the LIDAR you wish to monitor. |
| 5 | You'll also need the username and password for accessing the [wiki:LidarHttpServer LIDAR's web interface]. |
| 6 | 2. '''Do not change any values which are not present in this manual. This can affect LIDAR work or damage the instrument.''' |
| 7 | 3. '''Please follow this instruction first without doing actual gas refill! |
| 8 | Find specific menus, controls and boxes which are described in this manual and make familiar with them.''' |
| 9 | |
| 10 | === 4. Check for Laser pulses from last gas refill |
| 11 | 1. From //System Menu// select //Monitor & Control// |
| 12 | 2. At the bottom of page select monitorlog.txt from Internal storage box [#fig-14 (Fig. 14)] |
| 13 | 3. You will see text with Time from last gas refill //(TimeFLG)// in seconds |
| 14 | and pulses from last gas refill //(LSRPulseFLG)// [#fig-15 (Fig. 15)] |
| 15 | 4. Refill must be taken after 1E6 laser pulses, each month (2.6E6 seconds) |
| 16 | or if laser energy drops below 1500uJ (can be read from [#fig-4 Laser box] in //Monitor & Control//) |
| 17 | 5. Counters will reset after each successful gas refill procedure (manual |
| 18 | reset is possible using the RESET button near the Reset counters in |
| 19 | Lidar work mode box in //System Setting// [#fig-1 (Fig 1.)] |
| 20 | |
| 21 | === 5. Preparation for gas refill |
| 22 | 1. From //System Menu// select //System Settings// [#fig-1 (Fig. 1)] |
| 23 | 2. In Lidar work mode box [#fig-4 (Fig 4)] you will see 4 modes of operation |
| 24 | //(Standby, Continuous, Distance, Mixed)// with additional gas refill procedures |
| 25 | 3. In Lidar work mode box select //Standby//, press //Change//. |
| 26 | In pop-up box press //OK// (leave “Prevent this page from creating additional dialog” unchecked) |
| 27 | 4. From //System Menu// select //Monitor & Control// |
| 28 | 5. Check the status of Laser and Gas refill system [#fig-2 (Fig. 2)] or [#fig-4 (Fig. 4)]. |
| 29 | The normal //Laser Pressure// is from 600 to 700 kPa, //Laser Temperature// |
| 30 | must be below 45(50)^([#note-1 1])^. Status messages: all are Ready and Cyl. Closed. |
| 31 | |
| 32 | === 6. Starting gas refill |
| 33 | 1. From //System Menu// select //System Settings// |
| 34 | 2. In Lidar work mode box select //Refill laser*//, press //Change//. |
| 35 | In pop-up box press //OK// (leave “Prevent this page from creating additional dialog” unchecked) [#fig-3 (Fig. 3)] |
| 36 | 3. From //System Menu// select //Monitor & Control// |
| 37 | |
| 38 | ==== Following gas refill |
| 39 | Now follow the information from Laser and Gas refill system boxes [#fig-4 (Fig. 4)] to [#fig-13 (Fig. 13)] |
| 40 | 1. __Message: On start__ shows 30 seconds countdown timer |
| 41 | 2. __Message: Vacuum.__ The Valves checkbox-es will start to toggle. |
| 42 | '''Do not check Enable checkbox! Do not check manually any of valve |
| 43 | checkbox-es (this includes Main, Fill, Air, Vac, Hel, Purge, Cyl). |
| 44 | This can permanently damage the laser! ''' |
| 45 | 3. __Message: Prepump.__ Old gas is sucked out of laser. You can follow for laser gas pressure in Laser box |
| 46 | 4. __Message: Pump.__ When the laser pressure decreases below 120kPa gas |
| 47 | refill system will continue to pump uninterrupted the remaining gas |
| 48 | out for another 180 seconds. |
| 49 | 5. __Message: Cyl. working.__ Gas cylinder motor will start to open the |
| 50 | internal gas cylinder valve. |
| 51 | 6. __Message: Cyl. open or Fill.__ When cylinder in completely open, the |
| 52 | Cylinder pressure (in Gas refill box) will indicate high pressure |
| 53 | before the pressure regulator (above 10000kPa). |
| 54 | 7. __Message: Fill.__ Will indicate that gas refill system started to fill |
| 55 | laser with fresh gas from cylinder. The laser pressure will increase |
| 56 | 8. __Message: Cyl. Close.__ The cylinder valve starts closing when laser pressure reaches 600kPa |
| 57 | 9. __Message: Reductor.__ The gas refill system will stabilize pressure in pressure regulator and laser |
| 58 | 10. __Message: Stopped.__ The gas refill is finished successfully. |
| 59 | The pressure values in laser and cylinder will be around 650kPa and 500kPa. |
| 60 | |
| 61 | === 7. Finishing the gas refill |
| 62 | 1. Check the pressure values of Laser and Cylinder^([#note-2 2])^ Normal rages are around 650kPa and 500kPa. |
| 63 | 2. From //System Menu// select //System Settings// |
| 64 | 3. In Lidar work mode box select //Mixed//, press //Change//. |
| 65 | In pop-up box press //OK// (leave “Prevent this page from creating additional dialog” unchecked) |
| 66 | 4. The lidar will begin to operate |
| 67 | 5. From //System Menu// select //Data view// |
| 68 | 6. Wait for 5 to 10 seconds for the plot with signal to update. |
| 69 | An example of water spectrum with Raman scattering line is shown in [#fig-16 (Fig. 16)]. |
| 70 | |
| 71 | === 8. Troubleshooting |
| 72 | In any case of emergency STOP lidar operation and contact with our service team |
| 73 | using is[at]ldi-innovation[dot]eu email. Try to provide as many information as |
| 74 | possible with screenshots of web user interface. |
