Brown to 3V dc MI92 eries sensors may be wired for either two- or three-wire current-sinking operation. In the three-wire hookup, which requires two intrinsic-safety barriers, the sink current is 5 ma. The two-wire hookup, which requires one barrier, sinks ma (OFF state) and 2 ma (O state). MI92 eries sensors feature rugged, encapsulated construction, along with adjustable sensitivity and switchable light or dark operate. They also include Banner's exclusive Alignment Indicating Device system, which lights an indicator LD whenever the sensor sees its modulated light source, and pulses at a rate proportional to the received light signal strength.

7 VALU-BAM MI92 eries AMUR Hookups MI92 eries sensors are certified intrinsically safe OLY when used with certified energy-limiting intrinsically safe barriers. Banner does not manufacture such barriers; however, our applications engineers can refer you to suppliers of certified barriers that will interface with Banner sensors. MI92 eries sensors may be wired using Banner urrent Amplifier ontrol Module I3R2 (see page 9). ote from the hookup diagrams (page 8) that the installation may be made with either a single barrier (2-wire hookup) or with a double barrier (3-wire hookup). mitter-only units (MI9QD, RQD, and FQD) use the 2-wire hookup; all other models use either 2- or 3-wire hookup. In the 2-wire configuration, the sensor will act as a current sink, drawing less than ma in the OFF state and more than 2 ma in the O state. The user must provide a current sensing device ( current sensor in the diagram) to convert the current to a logic level. In the 3-wire configuration, the output may be used directly to control loads of less than 5 ma. In selecting the barrier, it is important to consider the barrier's resistance. The sensor must have at least volts across the brown and blue power leads for proper operation, and the barrier will cause a voltage drop due to its resistance. The formula that determines how much resistance is allowed is: R = (supply voltage volts) If the supply voltage is 2V dc, then the maximum resistance is 56 ohms. If the supply voltage is 8V dc, then the maximum resistance is 32 ohms. This includes the resistance of any current sensing device used (in the 2-wire configuration), so the barrier resistance must be further reduced by the current sensor resistance. ote that, in the 3-wire hookup, the positive load barrier is in series with the load. This will result in an apparent saturation voltage of the output that is higher than the sensor output by the amount of I x R (current times resistance) drop through the barrier. A positive input barrier is required for both supply and for load. The sensor s blue (negative supply) lead is normally connected to the ground terminal of the barrier. The user is responsible for proper installation and maintenance of this equipment, and must conform with the certification requirements relating to barriers and to maximum allowable capacitance and inductance of the field wiring. If in doubt about these requirements, our applications engineers can refer you to the appropriate authority. Banner ngineering orp. Minneapolis, M U..A. Tel: P/ 3396 rev. J
