This Week in the News : US EPA Budget Hearings

Posted by Rachel Stansel on Fri, Jun 16, 2017 @ 09:14 AM

This week, the US House of Representative's Appropriations Subcommittee held hearings to discuss President Trump’s 2018 budget request for the EPA. Newly appointed EPA Administrator Scott Pruit testified before the subcommittee regarding the proposed 30% cut to the EPA budget and the impact this might have both in terms of funding for various projects as well as the workforce reduction. The hearing lasted about two hours, with Representatives from both parties asking Administrator Pruitt questions about the cut. The main focus was the impact such cuts would have on the local and regional air, water and land pollution protection/cleanup programs that exist within their districts.

Using with Flow Mode - Win 7/8/10 Software for the Model 4000

Posted by Rachel Stansel on Mon, Jun 12, 2017 @ 11:25 AM

While many customers are accustomed to our operating software for the Series 4000/4020/4040, most are now beginning to use to our newest software as they upgrade to new computers with Win 7/8/10. To help you get started, or as a refresher if it's been awhile, we will be posting some short how-to videos that will help you get set up and running your unit like a pro in no time.

The software can be downloaded here. We recommend making sure you have the most current version by bookmarking the download page. You can also sign up for automatic notices of new versions by submitting a request through our contact page.

We started with how to initially add your instrument to the software and then moving to step two, adding cylinders. With that behind you, you were ready for the next step, which was adding your profile to the software.

These basic steps are all you need to start using the unit in one of 3 modes: concentration, flow and divider mode. The last video focused on Concentration Mode, and today we take a look at using Flow Mode.

Troubleshooting the Series 6103 - Part 9 - Photometer Issues Continued

Posted by Rachel Stansel on Tue, Apr 25, 2017 @ 10:45 AM

series-6100.jpg

Today, is the final article in our series on some of the common questions on troubleshooting the Series 6100 and S6103. The full user and service manuals can be found here.

Part 1 looked at what to do if your display does not come up, while Part 2 and Part 3 focused on what to do if you are seeing issues with flow. Part 4 looked at what to do when you were not getting any ozone regardless of the command. Part 5 and Part 6 looked at a variety of ozone issues in the Series 6100 specifically, while Part 7 looked at ozone issues with the Series 6103. Last time, in Part 8, we began to look at photometer related issues in the 6103.

Today, we will wrap up with how to troubleshoot a noisy photometer in a Series 6103.

Let us know if you have a specific issue you'd like us to cover!

Note!!: Customers who work on their units accept the risks of working on machinery and are responsible for taking all proper safety precautions. If in doubt, contact our service departmentNEVER unplug the ozone or photometer lamps while the unit is powered on. This can damage the circuitry.

System built after 11/2002 use a chassis with hinged side panels. This allows the side panels to be dropped for troubleshooting purposes. The cable lengths will allow the system to be powered on while the panels are dropped. However, always power down before dropping the panels.

Noisy Photometer

  1. As always, begin by verifying that all of the calibration data is properly entered in the System setup. This includes the ozone calibration, photometer calibration and you ADCs/DACs.
  2. Make sure that external electrical noise is being controlled. If unsure, add a UPS/power conditioner. It is also important to make sure the system cover is on and the screws are secure to create better chassis ground and make the system less susceptible to electrical noise.
  3. Next, be sure that the REFERENCE port pressure is not too high or too low. The optimal pressure is between 20 and 30 PSIG.
  4. Insufficient gas for the photometer will also create noise. The photometer requries 2 LPM. Make sure this 2 LPM is considered when deliverying gas to external analyzers.
  5. Make sure that the photometer lamp (red arrow) is backed out slightly in the block and that the thermistor (blue arrow) is bottomed out. 6103 lamp and thermistor.jpg
  6. Once you have checked these items, make sure that your photometer tube is clean and the glass windows of the photometer assembly are not chipped.The tube can be removed by loosening the knurled knob (blue arrow), which is done by rotating counter clockwise. It is best to use compressed air to clean out the tube.6103 photometer tube.jpgMaking sure the unit is turned off first, you can then visually inspect the glass windows (red arrows) to check for cracks or chips around the edges. Once reassembled, you will want to run the built-in leak test as follows:
    1. Be sure there is a source of gas connected to Port 1 at 25 PSIG.
    2. Select the LEAK function from the Main Menu, and then press START. The software will acquire Atmospheric Pressure, and then prompt for the outputsto be capped.
    1. Cap the Output Manifold, Vent and Exhaust ports. Use the caps supplied with the system.
    1. Press OK. The Leak Test will fill the volume of the system plumbing with gas from Port 1 to 5 PSIA above atmospheric pressure, and use pressure decay to calculate the leak rate. Any leak in excess of the maximum leak specification for the system (3 SCCM) will be displayed.
    2. The final step to troubleshoot is that the pump intact or outlet valves are not sealing properly. This will also cause low photometer readings, as you will have reference gas mixing in with sample gas. To test, place a small amount of restriction on the EXHAUST port (such as a 6" piece of 1/8" tubing). With the photometer loop OFF, in either FLOW or CONC mode, you should see the ozone level significantly drop and become very noisy. This is an indication that the pump intake or outlet valves have become partially blocked. We recommend that the unit be returned to our service department for a tuneup.

Troubleshooting the Series 6103 - Part 8 - Photometer Issues

Posted by Rachel Stansel on Thu, Apr 20, 2017 @ 10:45 AM

Let us know if you have a specific issue you'd like us to cover!

Note!!: Customers who work on their units accept the risks of working on machinery and are responsible for taking all proper safety precautions. If in doubt, contact our service departmentNEVER unplug the ozone or photometer lamps while the unit is powered on. This can damage the circuitry.

System built after 11/2002 use a chassis with hinged side panels. This allows the side panels to be dropped for troubleshooting purposes. The cable lengths will allow the system to be powered on while the panels are dropped. However, always power down before dropping the panels.

No Ozone Detected by the Photometer

  1. First, check that all of the photometer calibration data is properly entered in the System setup.
  2. Make sure that whatever ozone source you are using, whether internal or external, is producing ozone properly and that you have set the unit to read ozone in the external or internal respectively. This can be set by pressing the Menu bottom while in PHOTO/CONC/FLOW modes and using F2 to toggle.6013 Photometer 2.jpg
  3. Next check that the photometer lamp is illuminated. When in photometer mode, if the intensity of the lamp (displayed on the top line) are at or neat zero, your lamp is not on. This could be due to the lamp itself, or an issue with the PC414 or PC415. If a spare lamp is available, you can eliminate the lamp as the source of the problem by swapping them. BE SURE to never power on the unit without a lamp plugged into the PC415. When replacing the lamp, be sure it is backed out slightly to allow for expansion. If the issue is a board, contact us for assistance in repairing or replacing the board.
  4. If your lamp is properly illuminated, check to make sure the pump is enabled and running (for a detailed how to, check out Part 7 of our series here)
  5. If you are in photometer mode and are trying to read external source of ozone,make sure the vented source of ozone is connected to the SAMPLE IN port and zero air is connected to REFERENCE port at 25 PSIG.
  6. Verify that the pump is enabled and running (for a how to, check out Part 7 here).
  7. Check all steady state test points on PC415 are as below (ground = black arrow). PC415 Steady State TPsIn addition, the following TPs should be as follows:
    1. TP5 and 6: gas pressure and temp - approximately 2.45V (for 14.7 PSIA)
    2. TP8: block heater - between 4-5 volts (for temp between 25-50oC)
    3. TP12: block temperature - after warm up, between 4.9-5.1V (49-51oC)PC415 Photometer TP.jpg
  8. The final step to troubleshoot is that the photometer valve V1 or V2 is functioning.With the system power off, disconnect solenoid valve connector between PC401 and V2. Measure the DC resistance of V2. The resistance should be approximately 80 ohms. If resistance is good, PC401 high current driver circuit may be bad or solenoid valve plunger is stuck. We suggest you return the unit for evaluation and tuneup.

Troubleshooting the Series 6103 - Part 7 - Ozone Issues

Posted by Rachel Stansel on Mon, Apr 17, 2017 @ 10:45 AM

series-6100.jpg

Today, is Part 7 in our series on some of the common questions on troubleshooting the Series 6100 and S6103. The full user and service manuals can be found here.

Part 1 looked at what to do if your display does not come up, while Part 2 and Part 3 focused on what to do if you are seeing issues with flow. Part 4 looked at what to do when you were not getting any ozone regardless of the command. Part 5 and Part 6 looked at a variety of ozone issues in the Series 6100 specifically.

Today, we will look at how to troubleshoot ozone issues in a Series 6103.

Let us know if you have a specific issue you'd like us to cover!

Note: Customers who work on their units accept the risks of working on machinery and are responsible for taking all proper safety precautions. If in doubt, contact our service department!

 

Ozone is Drifting

  1. Begin by following the same initial steps as you would in a 6100 through step 5 below.
  2. NEVER unplug the lamp while the unit is powered on. This can damage the circuitry. Remove the ozone generator cover to access the ozone generator PC410 board.
  3. Make sure all ozone calibration data and ADCs (found in the SYSTEM mode) are valid and consistent with the last calibration.
  4. Verify that the system has warmed up long enough with ozone commanded. Especially when a system is new, the generator may drift up to 30 minutes before stabilizing. If the system is not used on a daily basis, drift will also be more common. We recommends that during the power up period, the system be run with ozone for 30 minutes to 1 hour to help condition the plumbing and burn in the lamp. 
  5. If you are still seeing drift after warm up, it is important to make sure that the ozone block temperature is stable. A drifting block temperature will cause the ozone to drift. The ozone block temperature should be stable between 48 and 51 degrees C and can be monitored on TP15 (yellow) on PC410 (see below). The voltage should be between 4.8 and 5.1 VDC. PC410 TP15.jpg
  6. Make sure that the ozone command is not drifting. This is checked on TP4 on PC410.
  7. Make sure that the ozone command and ozone pressure are not drifting. This is checked on TP4 and TP17on PC410.  TP17 (green TP indicated by the red arrow) is the ozone pressure reading, and TP 4 (blue TP just below and to the right of TP17) is the ozone command.PC410 TP17.jpg
  8. Unlike in a Series 6100, the command voltage is also impacted by pressure correction when the photometer control loop is off. If TP17 is drifting, disable pressure correction by going to PREFS from the ready screen and run again. If the ozone becomes stable, then there is a false indication of pressure drift and the PC410 should be replaced. The ozone would then need to be recalibrated, so we recommend this be done in the factory. You can contact our service department for assistance.
  9. If drift is consistent despite burn in and the above factors being stable, replace the ozone lamp.
  10. Although very uncommon, if a new lamp does not correct the drift either, if the optics have become contaminated by external contaminate (EX. Oil from compressor system), you may need to replace the ozone generator.Contact us for additional assistance, as a new ozone generator will require system recalibration.

 

Ozone is Unstable

  1. NEVER unplug the lamp while the unit is powered on. This can damage the circuitry. Remove the ozone generator cover to access the ozone generator PC410 board.
  2. Make sure all ozone calibration data and ADCs (found in the SYSTEM mode) are valid and consistent with the last calibration.
  3. If using the photometer control loop to control the ozone generator, turn the loop OFF. This will help to determine if the issue is being caused by the ozone generator or the photometer. This can be done from within Flow mode. Once flowing, press MENU and use F1 to toggle the O3 CTRL to OFF.6013 Photometer 1.jpg
  4. If the problem persists after turning off the photometer control loop, follow steps 6-8 below.
  5. If the instability goes away when the photometer is disengaged, you will need to troubleshoot the photometer. This is our next topic, and a link will be added once it is live!
  6. As outlined above in step 4 and 5, make sure you block temperature and pressure are stable.
  7. If all data is accurate and your temperature and pressure are stable, we recommend replacing the lamp.
  8. In rare occasions, if a new lamp does not correct the issue, a new PC410 is required. We recommend contacting our service department and having the unit evaluated at the factory to verify this.

Ozone is High and Uncontrolled Regardless of Command

  1. NEVER unplug the lamp while the unit is powered on. This can damage the circuitry. Remove the ozone generator cover to access the ozone generator PC410 board.
  2. This can happen if the Photometer control loop is on and the pump is either not activated or engaged. Verify the pump is on and functioning. From the main menu, go to PREFS and then to Photometer Prefs. Confirm both options are enabled. If they are, you will then confirm that the pump was not manually turned off. To do this, go to FLOW mode. Start flow and then press MENU. Verify the Pump is set to AUTO as in the below image, toggling with F3 if needed.
     
    6013 Photometer 2.jpg
  3. If the pump is engaged but still not functioning, can contact our service department for assistance.
  4. If your pump is working correctly, next you would make sure all ozone calibration data (found in the SYSTEM mode) is valid and consistent with the last calibration.
  5. If the data is all accurate, the problem is almost always the PC410 photo detector circuit has failed. The PC410 should be replaced. The ozone would then need to be recalibrated, so we recommend this be done in the factory. You can contact our service department for assistance.

 

We recommend contacting our service department and having the unit evaluated at the factory to verify this.
