• Zone Types– Warning Zone, further away from the machine, provides
operator feedback through a series of yellow LED lights mounted on each receiver
– Shutdown Zone, closer to the machine, provides operator feedback through red LED lights and disables certain functions such as tram and conveyor swing
• Operational Modes – Tram Mode defines a larger, full machine zone accounting for
increased machine speed– Cutting Mode defines a smaller, partial machine zone near the
bumper accounting for operator positioning away from haulage interaction

Proximity Detection Performance Issues
Proximity Detection Performance Issues
• Parasitic coupling – signal gets induced on nearby cables distorting field
• Magnetic interference – large metal objects distort field
• Other interference – Variable Frequency Drives
Performance issues appear to have been overcome by several systems
