The REMSAFE remote isolation system is designed to achieve up to SIL3/CAT4, the highest possible rating for machine safety. It meets or exceeds the Australian and International Standards for machinery and conveyor safety.
REMSAFE combines a safety-rated programmable logic controller, built-in redundancy and interlocks to ensure that energy sources are isolated at two independent points on command. Isolation is verified using both automated and manual ‘try-steps.' The status of the isolation and the health of the system are continuously monitored and displayed using indicator lights, HMI and SCADA transparent to both the operator and the Control Room. The system is failsafe.
In routine operation, automated racking out eliminates the hazard of arc flash.
Once activated, every step must be followed in sequence and is automatically verifiedby the system. A series of interlocks prevent shortcuts before theisolation lockout switch is released for lockout/tag out
