It is recommended that your analyzer be checked for accuracy on an annual basis.  If your calibration is off or is reading incorrectly, then follow the steps below for recalibration.  To verify the accuracy of your analyzer, simply connect the sample line to a cannister of known test gas and ensure that the reading on your controller screen matches the test gas.  Quotes for test gas can be requested via support@southteksystems911.zendesk.com or (910) 415-1880.

1. Turn generator off.
2. Close the ball valve connected to sample line at N2 storage tank.
3. Disconnect sample line from outside of electrical cabinet.
4. From the PLC (display) on the generator:

1.Press “Menu”

2.Enter Password (6557) and press the bottom right button (return key).

3.Select “sensor setup/calibration.”

4.Select “O2 PPM/% calibration”

For % Units:

1.Enter the contents of your known gas source in the field labeled “0-2% O2 Calibration Gas.”  This will be listed on the Test Gas cannister and is typically 1%.

2.Enter 20.9% in the field labeled “20-22% O2 Calibration Gas.”

For PPM units:

1.Enter the contents of your highest purity (lower PPM) known gas source in the field labeled “O2 PPM Low Calibration.”  This will be listed on the Test Gas cannister and is typically 10 PPM.

2.Enter the contents of your lowest purity (higher PPM) known gas source in the field labeled “800-1000 PPM Cal Gas.”  This will be listed on the Test Gas cannister and is typically 700 PPM.

3.Connect the provided regulator onto your higher purity (10 PPM) known gas source.

4.Connect the provided tubing over the sample line connector on the electrical cabinet.

5.Open the valve on the regulator and allow gas to flow to the analyzer for minimum of 5 minutes.

6.On the PLC there is a value displayed at the bottom of the calibration screen labeled “Current Raw”.

7.Take the “current raw” value and enter it in the top field (low side calibration)

8.Close the valve on the regulator.

9.Switch the regulator to your high side calibration gas.

10.Open the valve and allow gas to flow for 5 minutes.

11.On the PLC there is a value displayed at the bottom of the calibration screen labeled “Current Raw”.

12.Take the “current raw” value and plug in the 2^nd field (high side calibration)

13.Close the valve on the regulator.

14.Disconnect the tubing from the sample port.

15.Reconnect your sample line to the sample port.

16.Open the valve on the storage tank feeding the sample line.

This should complete calibration on your analyzer.  If you have trouble or require assistance, please give us a call at 910-415-1880.

1. Power down the unit and confirm that the pressure reading on the gauge above the filters reads 0 PSI.
2. Disconnect the drain lines from the filter bowls by pushing the orange rings towards the filter bowl, while pulling down on the poly lines.
3. Unscrew the filter bowls by hand by rotating the outer metal casing clockwise.
4. Pull down on the plastic filter bowls to remove them from the upper filter housing taking care to remove the O-rings.  The O-rings can be discarded.
5. The black filter element on the left can be removed from the upper filter housing by rotating clockwise and discarded.
6. The white filter element on the right can be removed from the plastic filter bowl by gently prying up on the black upper filter assembly with the O-ring removed.   Once removed from the filter bowl, rotate the lower piece of the filter assembly a quarter turn counter clockwise.  The white element can be discarded and replaced and then reassembled.
7. Fill the plastic filter bowl about half way with warm soapy water and shake with your hand covering the top opening.  Repeat for both bowls.  This will ensure that the float drain is clean and operational.
8. Remove and replace the O-rings on the lip of the plastic filter bowl.
9. Install the outer metal casing back onto the plastic filter bowl, taking care to line up the protrusion on the bottom with the opening in the metal casing.
10. Reinstall the filter housing and casing back into the upper filter assembly.  Only tighten hand tight and do not use a wrench.
11. Reinstall the poly drain lines by pushing up into the bowl until the push to connect fitting locks the line into place.
12. The compressor intake filter can be replaced by pushing down on the black filter bowl located on the top of the compressor and rotating counter clockwise.  Take care that the filter housing may be hot.
13. Turn on the unit and test for any leaks with a a spray bottle and soapy water.
14. Reset the filter alarm by holding the Down (-) key on the controller for 10-15 seconds.
