The IE-GuardFlex is the central control unit for 4B’s Distributed Hazard Monitoring Solution (DHMS). Using industrial Ethernet, it connects to and monitors multiple machine-mounted sensors via 4B’s advanced IE-Nodes. The system supports multiple machines, IE-Nodes, and sensors, interfacing directly with the machine MCC to perform a controlled stop if a hazardous condition is detected.
Typically located in the plant MCC and safe area, it connects via CAT6 Ethernet to IE-Nodes in hazardous areas. Common machines include bucket elevators, enclosed and open conveyors, chain conveyors, and roll stands. 4B sensors monitor conditions like belt slip, misalignment, bearing temperature, vibration, and blocked chutes.
Engineers can start node searches using the intuitive 7” touchscreen GUI. Found nodes can be configured, and sensors allocated to machines. The system supports 3-stage ALARM/STOP configurations per sensor, with output relays for ALARM and/or STOP conditions per sensor or machine. Common ALARM and STOP relays indicate alarm or stop conditions on any sensor.
