1. BB2 Central Unit BB2 is the central unit for the Cerlic sensors The measured value is converted to a linearized 4 20mA output signal The BB2 allows the user to easily adjust settings and serves as a display for the measured output The central unit also includes communication protocols for connection to various input systems 2009 03 04 C50AS5ENIO Table of contents 1 Deere E 3 2 A few words about this manual eere 3 Bi DOSIGQW e 3 4 Working DIDCIDIB e oaedduuadeueaevadutae va dete nu va du eau va debe ae va de aea geo ae na n 3 5 Installation and SIaPE Up uusssaeiciusiues cbusuuE caus HER CExEGYME CENE CHER ExEGIME CEeE YES DEus EUR 4 6 Unpacking the BB2 control DOX iiaueuies sinken nega nda iip Edna 5 Daimag6e8 i despite er see e paced E ce vegan te Pd que E ean ROUX RR D de ER EN ER REA S ae eet q uada de 5 PACK AGIING ERR RETE cee gible ca oles ped ae cnutt cd dente eved ede aae aa edd atin coer ede 5 eno me me 5 Options and accessories PNE ceres ME 5 7 Mounting of BB2 control DOX 2 ccusn sunu sas sucncnscsnsacucucuEuSusaEuSECECEEEE EE 6 8 Wiring ConnectlOnS uinci iidtua cu EE CE pan ERC LIE GE E YER FRGK Lo METRE MH anaana 6 9 Jumper settings ser rrr re cu cua cna rka dudo cuu cuc daa cu e codi 9 Analog OUtpUtsS iii iiic cene ra te ap beer oa cb api Ee ca dd bt Lave dest gece neu dec 9 D2.
