Basic Operating Theory
The Model PGA 3000 has been designed for the simultaneous analysis of CO, CO2 and CH4 in heat-treat furnace atmosphere gases. It has a 16 line by 40­character LCD display and a 4 x 4 keypad for the operator interface. Information is presented to the operator on various screens. The operator selects the appropriate page and enters the number using the keypad.
Numeric keypad key assignments.
0 – 9 are used to enter numeric data. * is the escape key and clears all numbers previously entered. # will display a specific menu, to select a specific page, press a numeric key (or two numeric keys) and then the # key. A is used as the ENTER key. B moves the cursor up. C moves the cursor down. D adds a decimal point to the data being entered on a screen, also toggles from
one furnace to the next on the data collection page.
Analyzer Start-Up Procedure
Turn the power switch on and allow the instrument to warm up until numbers appear on the default screen instead of ********. This process should take approximately two minutes. Accurate readings are only possible if the sample is taken from a clean (free of excess carbon buildup) sample port. The current state-of-the-art technology associated with IR sampling requires that a clean, soot free sample be available for analysis. A clean sample port will also increase the life of the filter elements, and reduce the possibility that soot will enter the unit and contaminate the sensors. On a furnace, the ideal port would be found on SSi’s Sample Port (Part Number
20263). If this is not available, the burnout port of a freshly burned-out Gold Probe would be an alternative, although this would still contain a trace amount of soot. On a generator, a dedicated sample port should be available. This sample port should be blown out before it is used, which will remove any soot that has accumulated in the line. This is accomplished by opening the valve without connecting the analyzer. Wait until the gas stream is clean before proceeding and connect the sample line to the sample port.

The ideal flow rate for sampling should be between 1.0 and 1.5 Standard Cubic Feet per Hour (SCFH). A visual indication of flow rate can be obtained through the mini flow meter located on the inside of the lid of the case, or by the digital flow meter on the left side of the display. The flow meter on the inside of the case also contains a dial that allows the user to restrict the flow if necessary to maintain an appropriate flow rate. If the sample gas is not under pressure, the internal pump can be used to extract it. The internal pump can be operated manually, or it can be turned on or off automatically when it detects low sample flow.
Filters
There are two filters that are intended to prevent soot or other contaminants from entering the unit. The first is an in-line filter that is located at the end of the sample tubing assembly. The second is a bowl filter located on the inside of the lid. Periodic inspection of these filters will ensure smooth operation. When new, the elements in both of these filters are white. Both are oriented in the sample stream in a manner that causes any contaminants to collect on the outside of the filter media, which allows for a visual inspection of filter status.
Condensation / Moisture
When a hot gas is cooled rapidly, moisture in the gas can condense and form water. This water can collect in the sample tubing assembly, and eventually enter the bowl filter. Care must be taken to ensure that no water enters the unit, as this will cause permanent damage to the sensors. The unit should be closely monitored during operation to determine if moisture is collecting in the bowl filter. If this is the case, the bowl filter basin can be removed and emptied by unscrewing it. Although water in the bowl filter will not cause damage to th e unit, this filter is not intended to be used as a condensation receptacle. If moisture has collected in the bowl filter, sampling should be stopped, and steps should be taken to prevent this from occurring before operation is resumed.
Battery
The battery in the PGA3000 in intended to provide more than enough power to operate the unit continuously for an eight-hour shift. When
Battery Low
is displayed on the LCD screen, the unit is in need of a charge. To charge the PGA3000, plug it into a 110 or 220VAC power source using the supplied power cord. The LED above the power cord input is red while the unit is being charged, and it will turn to green when charging is complete. For maximum battery life, do not recharge the battery after each use unless the
Battery Low
message appears on the screen. Reducing the number of times that the unit is charged will maintain the battery’s original storage capacity for a longer period of time.
