The End Unit is an active, loop powered unit that communicates with the HECU over a pair of copper wires. The pair of wires is routed through the normally closes contact of each device along the conveyor. The pair, known as the Safelne, provides an electrical interlock between all the normally closed switches of each device.
The end unit displays the status of the unit via 2 LEDS that indicate communication activity between the HECU and End Unit. The proprietary loop powered, CRC verified, synchronous and deterministic communication protocol is superimposed onto the Safeline™ link. Emergency stop trip signals from relevant devices are transmitted via the Safeline™ Communication channel. The End Unit is the last device installed on the Scanbelt Conveyor Belt Protection System.
