4. cting the installation location Dumo should be located so that measured data clearly represents dust concentration in a selected work environment Because of this the user should always think carefully what he wants to monitor and where the device should be placed For example Dumo can be placed close to the cement mill if the user is interested in the variation of the amount of dust particles during the process If the user is interested in dust concentration level in general then Dumo should be located in a more peaceful place some distance from the process There are still certain basic requirements for Dumo monitoring environment which one must take into account when preparing the measurements 1 Temperature in measurement environment should be between 20 C and 60 C The more stable temperature the better EIE eastern ENERGY EASTERN ENERGY SERVICES PTELTD SERVICES PTE LTD 60 Kaki Bukit Place 02 19 Eunos Tech Park Singapore SG 415979 Singapore Telephone 65 6748 6911 Fax 65 6748 6912 METERING AND INDUSTRIAL PRODUCTS Email info eesgroup com Website www eesgroup com SN SINTROL 2 Considerable humidity or condensed water is likely to drastically effect measurement 3 WIRING DUMO is connected with following cable pink 6 Power input 24 VDC gray 5 Power input GND brown 2 RS485 A white 1 RS485 B green 3 Auto setup Button procedure yellow 4 4 20 mA red 8
