Page 4: General Description
GG-R General Description Installation Locating the sensor The GG-R sensor is a +24 VDC, three-wire, 4/20 mA sensor for HFC, CFC and HCFC refrigerants which One of the most important considerations when utilizes proven IR (infrared) sensor technology for installing GG-R sensors is that they must be easily very accurate and reliable leak detection. -
Page 5: Installation Guidelines
GG-R Installation Guidelines: • Always mount the sensor vertically. • Must be easily accessible for calibration and 6.5" maintenance. 2.0" • Mount the sensor close to the potential leak source. • For optimum leak detection, mount sensor 1’ – 2’... -
Page 6: Wiring
GG-R Wiring Electrical wiring must comply with all applicable codes. Electrical Power: 24 VDC regulated, 300 mA. Output: Linear 4/20 mA output. Monitoring equipment may have a maximum input impedance of 700 ohms. Cable Recommendation: 18/3 shielded, stranded cable with drain wire (General Cable C2535A or equivalent). -
Page 7: Operation
• Apply span gas at 0.5 to 0.8 L/min. Calibration • Sensor should react to gas within 20 seconds. The GG-R Sensor comes factory calibrated and should • Once the output signal has peaked (or 3 minutes require only minimal adjustments after installation. -
Page 8: Zero-Filter Mode
• Adjust the 4mA pot until the control panel reads Zero adjustment zero. Zero-filter mode (deadband mode) The default operation mode of the GG-R Sensor has Calibration an active deadband to eliminate the display of signals gas port within the zero noise of the sensor. To change or view the zero-filter mode, follow the procedure below: •... -
