9.2 Performance Problems

When the response from a span check is outside the control limits, the cause for the drift should be determined, and corrective action should be taken. Some of the causes for drift are listed below:

NOTE

It has been our experience that about 50% of all analyzer performance problems are sooner or later traced to leaks in some part of the system.

1.Fluctuations in flow. Such as leaks or plugged orifices.

2.Lack of preventive maintenance.

3.Change in zero air source.

A.Air containing NO leaking into zero air line.

B.Saturation of charcoal and/or Purafil scrubbers.

4.Change in span gas concentration.

A.Zero air or ambient air leaking into span gas line.

B.Permeation tube or cal gas tank exhaustion.

5.Leak in NO/NOx or Pre-reactor switching valves.

6.Loose pneumatic fittings.

9.2.1 AC Power Check

1.Check that power is present at main line power input. Verify that correct voltage and frequency is present. If unit is set for 240 VAC and is plugged into 115 VAC it will appear as no power fault.

2.Check that the unit is plugged into a good socket. Analyzer must have 3-wire safety power input.

3.Check circuit breaker. Circuit breaker is part of the front panel power switch. It is set each time the instrument power is turned on. If there is an internal short causing a trip, the switch will automatically return to the OFF position when an attempt is made to turn it on.
