5.  Disconnect the current loop option PCA from the appropriate connector on the motherboard (see Figure 

5-2). 

6.  Each connector, J19 and J23, requires two shunts. Place one shunt on the two left most pins and the 

second shunt on the two pins next to it (see Figure 5-2). 
  6 spare shunts (P/N CN0000132) were shipped with the instrument attached to JP1 on the back of 

the instruments keyboard and display PCA. 

7.  Reattach the top case to the analyzer. 
8.  The analyzer is now ready to have a voltage-sensing, recording device attached to that output. 
9.  Calibrate the analog output as described in Section 7.4.3. 

5.5. EXPENDABLES AND SPARES KITS (OPTIONS 42A, 45) 

Expendables Kit, Option 42A:  one-year supply of replacement particulate filters (47mm diameter)  

Spares Kit, Option 45: spare parts for one unit  
 

5.6. CALIBRATION VALVES (OPTIONS 50A, 50B, 50E, 50H) 

The GFC 7001E/EM Gas Filter Correlation Carbon Monoxide Analyzer has a variety of available options 
involving various valves for controlling the flow of calibration gases.  From an operational and software 
standpoint, all of the options are the same, only the source of the span and zero gases are different.   
 

5.6.1. GENERAL INFORMATION RELATED TO ALL VALVE OPTIONS 

5.6.1.1. Gas Flow Rate 

  The minimum span gas flow rate required is 800 cm

3

/min; however, the US EPA recommends that there 

be an excess of flow at least 800 cm

3

/min of calibration gas.   

  Zero air will be supplied at ambient pressure from the local atmosphere. 

5.6.1.2. Valve Control 

The state of the various valves included in these options can be controlled as follows: 

  Manually from the analyzer’s front panel by using the SIGNAL I/O controls located under the DIAG Menu 

(see Section 7.3), 

  By activating the instrument’s AutoCal feature (see Section 9.4), 
  Remotely by using the external digital control inputs (see Section 9.3.3.3), or 
  Remotely through the RS-232/485/Ethernet serial I/O ports (see Appendix A-6 for the appropriate 

commands). 

 

5.6.2. ZERO/SPAN VALVE (OPTION 50A) 

This valve option is intended for applications where: 

  Zero air is supplied by a zero air generator like the Teledyne’s M701 and; 
  Span gas is supplied by Gas Dilution Calibrator like the Teledyne’s M700E or M702.   

Internal zero/span and sample/cal valves control the flow of gas through the instrument, but because the 
generator and calibrator limit the flow of zero air and span gas, no shutoff valves are required.
