Teledyne SERIES 4030 Analyzer Operation, Verification of the Flame Guard Circuit, Sample Pump

Operation

the temperature controller is maintaining the temperature set point) and the red flame failure lamp is on. See Figure 4-1.

The Series 4030 will automatically attempt a flame ignition sequence following the warm up period, which has been preset at the 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 4.3.1.

4.3.1 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 the vicinity zero, the flame will be 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.

4.3.2Ignition 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.

4.3.3 Sample Pump

A built-in Sample Pump is provided to draw Sample Gas from the Sample line. The gas flow rate should be maintained at about 1000 to 1200 cc/minute using the Front Panel FLOW CONTROL valve (clockwise increases flow).

4.4 Analyzer Operation

Although the Model 4030 has been programmed for your application at the factory, it can be further configured at the operator level.
