PERSEUS ATEX & IECEx Exd, Exi & INDUSTRIAL SWITCHES INTRODUCTION The Perseus pressure, vuum, differentil pressure, temperture, nd level swithes re designed for use in environments where explosive gses n be present (e.g. Gs fields, Oil rigs nd Chemil plnts et.) nd hve been ATEX nd IECEx ertified s detiled overlef (SIL2 - IEC61508 proven relibility). These swithes re mnuftured from high qulity sting whih offers robust onstrution nd protetion to IP67 for use within hevily polluted industril environments. A speil feture of the instruments is the seprtion of the flmeproof nd djustment omprtments llowing for sfe on-site djustment of the set point with power on nd the swith in opertion. Perseus Exd swithes must be instlled in ordne with BS EN 60079-14 CALIBRATION The design fetures simple form of djustment ginst librted sle. This enbles user to order swithes set t predetermined point or stok mid rnge setting nd djust swithes to suit the prtiulr pplition. The set point n be sfely djusted with the swith eletrilly live. Adjustment is mde by removing the ess over nd rotting the set point djuster using the supplied tommy br stowed to the right of the sle plte. The setting is red from the entre of the set point djuster ginst the librted sle. Rottion to the left will inrese the set point nd to the right derese it.
