The BM 700 level gauge is designed solely for measuring the level, distance, volume and reflection of liquids, pastes, slurries, particulate materials and solids. The BM 700 level gauge does not form part of an overfill protection system as defined in the WHG (= German water pollution regulation).
2 Installation Most of the BM 700 versions are supplied in fully assembled condition. In this case, you may skip this chapter. However, if a device should be delivered in parts, or parts are subsequently replaced, the following should be noted.
2.2 Mechanical installation Hazardous-duty systems: • The BM 700 Ex is certified in conformity with European Standard for use in Zone 0, 1 and 2 hazardous locations (dependent on version). • Attention is drawn to the data and information given on the nameplate of the converter, the nameplate of the flange and the specifications in the approval certificates.

Installation on the tank • Do forget gasket when positioning the BM 700 on the tank nozzle flange. Align BM 700 and gasket, slightly tighten nuts on stud bolts (by hand). • Press shielding strip C* in the gap between tank and BM 700 flanges and secure with strap retainer S* (both items included with supply).
Dimensions (W×H×D): 55×75×110 mm, usable for rail mounting Class of protection The BM 700 level gauge is designed for safety class 1 in conformity with VDE 0106 Part 1. 24 V DCAC supply When connected to a “functional extra-low voltage with safety separation“ power source (SELV or PELV) in accordance with VDE 0100, Part 410 or equivalent (inter)national regulations, connection of a safety conductor (PE) is not required.
PC. Connect the current output of BM 700 over a load between 120 Ω and 350 Ω to the Smart adapter (delivered together with PC-CAT) and connect it with a serial port of the PC.
