SAFETY MESSAGES
Your safety and the safety of others is very important. We have provided many important safety messages in this manual. Please read these messages carefully.
A safety message alerts you to potential hazards that could hurt you or others. Each safety message is associated with a safety alert symbol. These symbols are found in the manual and inside the instrument. The definition of these symbols is described below:
GENERAL SAFETY HAZARD: Refer to the instructions for details on the specific hazard.
CAUTION: Hot Surface Warning
CAUTION: Electrical Shock Hazard
TECHNICIAN SYMBOL: All operations marked with this symbol are to be performed by qualified maintenance personnel only.
CAUTION
The analyzer should only be used for the purpose and in the manner described in this manual. If you use the analyzer in a manner other than that for which it was intended, unpredictable behavior could ensue with possible hazardous consequences.

3. GETTING STARTED
3.1. Unpacking and Initial Set Up
CAUTION
To avoid personal injury, always use two persons to lift and carry the Model GFC7000E.
1.Verify that there is no apparent external shipping damage. If damage has occurred, please advise the shipper first, then Teledyne Analytical Instruments.
2.Included with your analyzer is a printed record of the final performance characterization performed on your instrument at the factory. This record, titled Final Test and Validation Data Sheet (part number 04307) is an important quality assurance and calibration record for this instrument. It should be placed in the quality records file for this instrument.
3.Carefully remove the top cover of the analyzer and check for internal shipping damage.
•Remove the set screw located in the top, center of the rear panel.
•Remove the four screws fastening the top cover to the unit (two per side).
•Lift the cover straight up. Do not slide backwards.
NOTE
Some versions of the GFC7000E CO2 Analyzer may have a spring loaded fastener at the top center of the rear panel and as many as eight screws (four per side) fastening the top cover to the chassis.
NOTE
Static sensitive parts are present on PCA (Printed Circuit Assemblies). Before touching PCAs, touch a bare metal part of the chassis to discharge any electrostatic potentials or connect a grounding strap to your wrist.
CAUTION
Never disconnect PCAs, wiring harnesses or electronic subassemblies while under power.
4.Inspect the interior of the instrument to make sure all circuit boards and other components are in good shape and properly seated.

5.Check the connectors of the various internal wiring harnesses and pneumatic hoses to make sure they are firmly and properly seated.
6.Verify that all of the optional hardware ordered with the unit has been installed. These are listed on the paperwork accompanying the analyzer.
7.Once you have determined that no shipping damage exists, and the unit includes all expected hardware options, remove all red colored shipping screws from the bottom of the chassis as shown in Figure 3-1.

When the instrument is in its default configuration, the A1 and A2 channels output a signal that is proportional to the CO2 concentration of the sample gas. Either can be used for connecting the analog output signal to a chart recorder or for interfacing with a datalogger.
The third analog output, labeled A3 is special. It can be set by the user (see Section 6.9.9) to output any one of the parameters accessible through the <TST TST> keys of the units sample display.
The standard configuration for these outputs is mVDC. An optional current loop output is available for each.
Output A4 is not used on the Model 306E.
Pin-outs for the analog output connector at the rear panel of the instrument are:

•The default analog output voltage setting of the GFC7000E CO2 Analyzer is 0 – 5 VDC with a range of 0 – 500 ppm.
•TO change these settings, see Sections 6.9.4 and 6.7 respectively.
10.If you wish utilize the analyzer’s status outputs to interface with a device that accepts logiclevel digital inputs, such as programmable logic controllers (PLC’s) they are accessed via a 12pin connector on the analyzer’s rear panel labeled STATUS.

NOTE
Most PLC’s have internal provisions for limiting the current that the input will draw from an external device. When connecting to a unit that does not have this feature, an external dropping resistor must be used to limit the current through the transistor output to less than 50mA. At 50mA, the transistor will drop approximately 1.2V from its collector to emitter.

1.Attach a sample inlet line to the sample inlet port. The SAMPLE input line should not be more than 2 meters long.
NOTE
Ideally, the pressure of the sample gas should be at ambient pressure (0 psig). Maximum pressure of sample gas should not exceed 1.5 in-Hg over ambient.
In applications where the sample gas is received from a pressurized manifold, a vent must be placed as shown to equalize the sample gas with ambient atmospheric pressure before it enters the analyzer.
This vent line must be:
•At least 0.2m long
•No more than 2m long and vented outside the shelter or immediate area surrounding the instrument.
04584 Rev A1 |
17 |
Model GFC7000E Instruction Manual |
Getting Started |
2.Attach sources of zero air and span gas (see Figures 3-3 through 3-8 inclusive).
•Span Gas is a gas specifically mixed to match the chemical composition of the type of gas being measured at near full scale of the desired measurement range.
In the case of CO2 measurements made with the Teledyne Analytical Instruments Model GFC7000E Analyzer it is recommended that you use a gas calibrated to have a CO2 content equaling 80% of the range of compositions being measured.
EXAMPLE: If the application is to measure between 0 ppm and 500 ppm, an appropriate Span Gas would be 400 ppm. If the application is to measure between 0 ppm and 100 ppm, an appropriate Span Gas would be 80 ppm.
•Span Gas can be purchased in pressurized canisters or created using Dynamic Dilution Calibrator such as the Teledyne Analytical Instruments Model 700 and a source of dried
air scrubbed of CO2 such as a Teledyne Analytical Instruments Model 701 Zero Air Generator in combination with a canister of indicating soda-lime.
•Zero Air is similar in chemical composition to the earths atmosphere but scrubbed of all components that might affect the analyzer’s readings.
In the case of CO2 measurements this means CO2 less than 0.1 ppm of CO2 and Water Vapor. Zero Air can be purchased in pressurized canisters or created using a Teledyne Instruments Model 701 Zero Air Generator in combination with a canister of indicating soda-lime.
3.Attach an exhaust line to the exhaust outlet port.
•The exhaust from the pump and vent lines should be vented to atmospheric pressure using maximum of 10 meters of ¼” PTEF tubing.
CAUTION
Venting should be outside the shelter or immediate area surrounding the instrument.
4. Attach a source of dried air scrubbed of CO2 to the purge inlet port
NOTE
The source of purge air should be at 20-25 psig and capable of maintaining a flow of at least 0.5 liters/min.
Purge source air pressure should not exceed 35 pisg
5.Once the appropriate pneumatic connections have been made, check all pneumatic fittings for leaks using a procedure similar to that defined in Section 9.3.3.
