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: • Multidrop Mode is supported. • Burst Mode is not supported. Electrical connection (point-to-point or multidrop): refer to sections 4.1 – 4.4 of the „Installation and Operating Instructions. BM 70 A/P, BM 700, BM 702“. 1.
Remote Operation Instructions BM 70 A/P, BM 700, BM 702 HART due to any reason (say, for testing purposes) wants these units to be same, he can either “equalize” them from remote (Configuration/Test ➪ Installation ➪ Display ➪ Unit length/Unit conversion for HC275 or “Process Input” configuration tab for AMS) or from the device keypad (functions 3.2.2/3.2.3). 4 HART Communicator 275 (HC275) 4.1 Installation The HC275 has to be programmed with the BM 70 A/P /700 /702 HART Device Description.
Remote Operation Instructions BM 70 A/P, BM 700, BM 702 HART For installing the DD with the Installation Kit refer to the “AMS User's Guide” section 3:”Managing HART Devices” / “Adding new Device Types to AMS” / “Install Device Types Manually”. 5.2 Operating Refer to the BM70 A/P /700 /702 Menu Tree AMS (Attachment B). Due to AMS requirements and conventions the BM 70 X operation differs a little from operation with HC275 and via local keypad.
Remote Operation Instructions BM 70 A/P, BM 700, BM 702 HART instrument is in multidrop, changing of the ‘PV is’ value (Primary Variable code) affects only Primary Variable digital value (and corresponding settings) whilst the current output function (‘Function I’ on the “Analog Output” tab) remains switched “Off”. Otherwise - when the instrument has the ‘0’ bus address – changes in Primary Variable assignment are traced at analog output and its function.
