Model GFC7000T Carbon Dioxide Analyzer 1. OVERVIEW The Model GFC 7000T is a close derivative of the Model GFC 7000TA CO Analyzer. The 2 main differences are as follows. The optical bench is longer (14 m), making the instrument more sensitive at low CO 2 levels. The instrument has a user-selectable full scale range of 0-100 PPB to 0-100 PPM of CO . 2 The rear panel is different. There is an extra pneumatic port for the exhaust of the purge gas to the GFC wheel. Also, there are relay ala

Model GFC7000T Carbon Dioxide Analyzer Table 4-1. Model GFC 7000T Pneumatic Connections Rear Panel Label Function Connect a gas line from the source of sample gas here. SAMPLE Calibration gasses are also inlet here on units without zero/span valve option installed. Connect an exhaust gas line of not more than 10 meters EXHAUST long here. On units with zero/span valve option installed, connect a PRESSURE SPAN gas line to the source of calibrated span gas here. VENT SPAN Not used

Model GFC7000T Carbon Dioxide Analyzer EXAMPLE: If the application is to measure between 0 ppm and 50 ppm, an appropriate Span Gas would be 40 ppm. If the application is to measure between 0 ppm and 100 ppm, an appropriate Span Gas would be 80 ppm. 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 CO 2 measurements this means CO less than 0.1 ppm of CO and Water Vapor. 2 2 Ze

Model GFC7000T Carbon Dioxide Analyzer 6. RELAY ALARM OUTPUTS (AIR PRODUCTS CONFIGURATION) There are 4 relay alarm outputs (AL1-AL4) on the rear panel. AL1 is for “system okay”, AL2 is for “high range status” and AL3 is for “zero calibration status” AL4 is not used The AL1 relay is energized when the system is okay and de-energized when the system has a fault. The AL2 relay is energized when the high auto-range is in use and and AL3 relays energize when the the instrument
