Page 4: General Description
GG-CO General Description Installation Locating the sensor The GG-CO sensor is a +24 VDC, three-wire, 4/20 mA sensor for carbon monoxide which utilizes proven One of the most important considerations when electrochemical sensor technology for fast and installing GG-CO sensors is that they must be easily accurate detection. -
Page 5: Installation Guidelines
GG-CO Installation Guidelines: • Remove and discard protective cell cap • Always mount the sensor vertically. 6.5" • Must be easily accessible for calibration and 2.0" maintenance. • Mount the sensor close to the potential leak source. • For optimum personnel protection, mount sensor in breathing zone (approximately 5 feet from floor). -
Page 6: Wiring
GG-CO Wiring Electrical wiring must comply with all applicable codes. Electrical Power: 24 VDC regulated, 350 mA. Output: Linear 4/20 mA output. Monitoring equipment may have a maximum input impedance of 700 ohms. Cable Recommendation: 20/3 shielded cable (General Cable C2525A or equivalent). Length of cable to sensor should be no greater than 1,500 feet. -
