© Siemens AG 2012 Process Protection Motion sensors Milltronics Millpulse 600 ■ Overview ■ Design Mounting The Millpulse 600 should be mounted in an area classified as non-hazardous, that is suitable to the enclosure rating and materials and is within the temperature range specified. The cap should be accessible to allow for wiring and viewing of the status display LED. When mounting the Millpulse onto a vibration-free structure, use the supplied mounting flange to ensure that there is no danger of the target damaging the unit. Where possible, mount the probe so the cable inlet is pointing downward to avoid accumulation of condensation in the casing. Where wiring must be run in conduit, use a flexible conduit for easier removal or adjustment of the probe. Keep the Millpulse away from high voltage or current runs, contactors and the variable frequency drives. Do not connect the Millpulse 600 directly to supply. Milltronics Millpulse 600 is a heavy-duty 2-wire motion sensor that provides solid state switch output to PLCs between 18 to 135 V AC or DC. ■ Benefits • • • • • Up to 100 mm (4 inch) gap between Millpulse and targets Two-wire unit PLC compatible Rugged, low maintenance suitable for tough environments Visual indication of target triggered pulses ■ Application Millpulse supplies cost-effective equipment protection even in the harshest conditions. This rugged unit is impervious to dust, dirt, build-up, and moisture, and is ideal for such primary industries as mining, aggregate, and cement plants. Operating where other systems are prone to failure, the non-contacting design eliminates the need for lubricating, cleaning, and part replacement. It will reduce downtime and clean-up expenses associated with conveying equipment failure. Its pulse output can be used to minimize spillage, prevent damage, detect fire caused by belt slippage at the head pulley, and warn of other conveyor malfunction. ■ Technical specifications Mode of operation Measuring principle Disruption of magnetic field by ferrous target Typical application Provides pulse output to PLC when monitoring screw conveyor flight Rated operating conditions Operating temperature -45 ... +60 °C (-49 ... +140 °F) Design Probe body Aluminum Process mounting 2" NPSL Connection box Aluminum, ¾" NPT conduit entrance, 4 screw terminals for max. 12 AWG (3.30 mm2) wire size Gasketing Neoprene Display Red LED for switch status Enclosure rating Type NEMA 4X, 6, IP67 Shipping weight 2 kg (4.4 lb) Power supply Switching capability Voltage • 18 ... 48 V AC/DC • 60 ... 135 V AC/DC Current • 5 ... 400 mA continuous, 2 A surge for 20 ms at 1 operation per second Voltage drop 8V Residual current 1.5 mA Switch duration On: 50 ms minimum Off: 50 ms minimum Dynamic range Minimum 6 pulses per minute Maximum 600 pulses per minute Certificates and approvals CSAUS/C, CE, C-TICK The Millpulse 600 offers underspeed, overspeed, differential speed, and speed indication functions by a PLC.

If your PLC does not meet the requirements, a resistor across the PLC inputs can be used to increase the switching current. 6 Siemens FI 01 · 2013 6/25
