Page 5: Introduction
(LEL) in air. As determined by application requirements, the SGOES is factory calibrated with one of eight hydrocarbon-based gases (typically methane or propane). Conversion factors are used to correct for gases other than the factory calibration gas. -
Page 6: Principles Of Operation
SGOES Infrared Combustible Gas Detector 820-0006 Operating Manual Principles of Operation Operation is based on selective signal disruption by hydrocarbon molecules. An infrared light source is reflected to a set of optical detectors that simultaneously monitors the infrared power at multiple wavelengths of the infrared spectrum. If no gas is present, the photodetectors will receive all of the power radiated by the IR source. -

Page 21: Sgoes Calibration Using Magnetic Wand
Magnetic field calibration can only be performed with the same calibration gas (type and concentration) used to establish the factory settings for the detector. Standard gases used to establish factory setting for the SGOES detectors are methane and propane. Prior to magnetic field calibration, determine the proper calibration gas and concentration. - Page 22 Apply the magnetic wand to the ESP logo and remove. The LED status light will appear SOLID GREEN. This indicates that the SGOES detector is now in operational mode and that the output signals are enabled. Replace the weatherproof protective cover on the detector.

Page 23: Troubleshooting
The SGOES does not contain any user-serviceable parts. Any repair of the SGOES should be performed by ESP Safety personnel. Any attempt to repair or service the SGOES by unauthorized personnel will void the product warranty. Page 22... -
Page 24: Maintenance
• Performance test. Maintenance Activities The SGOES needs very little routine maintenance; but periodic checks for proper system function and calibration are strongly advised. The frequency of these checks should be determined by the specific installation. Although the fault-detection circuitry continuously monitors for various problems, it does not monitor external response equipment or wiring. -
Page 25: Warranties
