Remote Operation Instructions BM 70 A/P, BM 700, BM 702 HART 1 General Information The BM 70 A/P, BM 700, BM 702 are all the two-wire transmitters with 4..20mA current output and HART® capability. General characteristics of the BM70 X HART® interface: •...
5.1 Installation If the BM 70 A/P /700 /702 Device Description is not already installed on the AMS System a so called Installation Kit BM 70 A/P /700 /702 HART AMS is needed (available on floppy disk from KROHNE or as download from KROHNE Internet page).
“wide” configuration (e.g. any corresponding to BM 70 A) to a “narrow” one (e.g. any of BM 702) can lead to a so- called ‘Unknown enumerator’ situation (when transferred value is replaced with ‘**********’ in configuration- “receiver”...
