This unit features one person calibration andcan virtually self-calibrate by simply activating amagnetic switch and applying gas. It is designed todetect hydrogen sulfide in parts per million (ppm) levelsand provide status indication and alarm outputs.All of the S4000TH electronics are contained within anexplosion-proof housing so that sensor information canbe processed at the sensor site. It provides a 4-20 mAsignal which is proportional to 0 to 100% of the detectionrange at the sensor. In addition, the S4000TH includeswarning, alarm and fault relay contacts that can be usedto indicate an alarm or fault condition, and dualredundant Modbus or HART communications.Configurations with relays, Modbus and HART are availableto meet many needs.The S4000TH includes a three (3) digit LED display.This local digital display continuously indicates gasconcentrations during normal operation and in thecalibration check mode, calibration prompts duringcalibration mode, display codes during the setup modeand eight fault codes. The S4000TH has four different operating modes. First,the normal operating mode in which alarms are active andthe display and 4-20 mA readings are proportional to thegas concentration at the sensor. Second, the gas checkmode that allows the user to apply a gas and check thesensor response while alarm outputs are inhibited. Third,a calibration mode in which gas is applied to the sensor tocalibrate the unit. Finally, a set-up mode which allows theuser to review or change setup options such as relaysettings, sensor range, and Modbus parameters.Selecting Setup Mode on the S4000TH is accomplishedby using the magnetic switch, HART or Modbus command.Options• Sensor Range (0-20 ppm, 0-50 ppm, 0-100 ppm)• Energized/de-energized relays• Latching/non-latching relays• Alarm setpoints for relays• Baud rate, data format, and address for eachModbus channelProtection for life.GENERAL MONITORSIntelligent Sensor forH2S Gas DetectionH2SMODEL S4000THwww.generalmonitors.comLake Forest, CA26776 Simpatica CircleLake Forest, California 92630Tel: +1-949-581-4464Fax: +1-949-581-1151Email: info@generalmonitors.comHouston, TX9776 Whithorn DriveHouston, Texas 77095Tel: +1-281-855-6000Fax: +1-281-855-3290Email: gmhou@generalmonitors.comIrelandBallybrit Business ParkGalwayRepublic of IrelandTel: +353-91-751175Fax: +353-91-751317Email: info@gmil.ieSingaporeNo. 2 Kallang Pudding Road#09-16 Mactech BuildingSingapore 349307Tel: +65-6748-3488Fax: +65-6748-1911Email: genmon@gmpacifica.com.sgUnited Arab EmiratesP.O.
