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.

4.4.2 Ignition 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:
