4 PERSEUS ATEX & IECEx Exd, Exi & INDUSTRIAL SITCHES INTRODUCTION The Perseus pressure, vcuum, differentil pressure, temperture, nd level switches re designed for use in environments where explosive gses cn be present (e.g. Gs fields, Oil rigs nd Chemicl plnts etc.) nd hve been ATEX nd IECEx certified s detiled overlef (SIL2 - IEC68 proven relibility). These switches re mnufctured from high qulity csting which offers robust construction nd protection to IP67 for use within hevily polluted industril environments. A specil feture of the instruments is the seprtion of the flmeproof nd djustment comprtments llowing for sfe on-site djustment of the set point with power on nd the switch in opertion. Perseus Exd switches must be instlled in ccordnce with S EN CALIRATION The design fetures simple form of djustment ginst clibrted scle. This enbles user to order switches set t predetermined point or stock mid rnge setting nd djust switches to suit the prticulr ppliction. The set point cn be sfely djusted with the switch electriclly live. Adjustment is mde by removing the ccess cover nd rotting the set point djuster using the supplied tommy br stowed to the right of the scle plte. The setting is red from the centre of the set point djuster ginst the clibrted scle. Rottion to the left will increse the set point nd to the right decrese it.
