Azbil Corporation No. SS2-MGG200-0200 - 5 - Signal cable Dedicated cable: model MGA12W (O.D. 11.4 mm, 0.75 mm2) or equivalent (CVVS, CEEV, etc.) Excitation cable Dedicated cable: model MGA12W (O.D.10.5 mm, 2 mm2 diameter) or equivalent (CVV and others) For FM/CSA Explosionproof model The wiring of model MGG17 detector is shown below with the diagram. . A specially designed shielded cable must be used for flow rate signal transmission from the detector to the converter because the electrodes from a high impedance source generating very low e.m.f. . The power supply to the converter is limited to 250V r.m.s. . The detector enclosure rated type 4X provides adequate weather and corrosion resistance. . Ambient temperature: -10°C to +60°C . Process fluid temperature: -40°C to +120°C Note: . 1.Power supply and internal voltage of Ordinary Equipment to the Earth shall not exceed AC 250 V 50/60 Hz. 250 V DC in case of Normal/Fault. 2.
