factory. If the ignition process fails, the instrument will attempt to ignite the flame 4 more times. If it continues to fail after the fifth attempt, a flame failure message will appear on the display. If this occurs refer to Section 5.

4.4.1 Verification of the Flame Guard Circuit

The operation of the flame guard circuit has been checked at the factory, but should be re-verified during start-up. Use the following procedure after ignition of the flame has been achieved:

1.Turn off the fuel at the supply cylinder.

2.Observe the fuel pressure gauge on the analyzer control panel. The gauge indication will decay as the fuel in the line is exhausted. When the gauge reading reaches near zero, the flame will extinguish as the fuel solenoid shuts off the fuel supply. The analyzer will automatically try to re-ignite. After 5 attempts, it will display: flame failure, check air, fuel and the flame failure LED will be on.

3.Open the cylinder supply valve and re-ignite the flame by pushing the up and down buttons simultaneously.

4.4.2Ignition and/or Flame Guard Circuit Failure

If the flame ignition or guard circuits do not operate as described in the above two sections, set the instrument fuel regulator to the recommended pressure. If still fails to ignite, proceed as directed in Chapter 5: Maintenance & Troubleshooting.

4.5 Sample Pump

A built-in sample pump is provided to draw sample gas from ambient air. The gas flow rate should be maintained at about 1000 to 1200 cc/minute using the Front Panel flow control valve (clockwise increases flow). See Figure 1-1.

4.6 Analyzer Operation

Although the Model 4060 has been programmed for your application at the factory, it can be further configured at the operator level. Depending on the specifics of the application, this might include all or a set of the following procedures:
