How SMART assets evolve safety<\/strong><\/span><\/p>\n
Predictive maintenace:<\/strong><\/p>\n
Operations of safety devices per shifts are captured<\/p>\n
Monitoring number of operations helps predict when device is at end of life<\/p>\n
Information is available for maintenance staff to replace device<\/p>\n
Device can be replaced at next planned maintenance schedule<\/p>\n
Machine uptime from Smart Safety data<\/strong><\/p>\n
Machine operator opens interlocked guard door to fix tape. Device operation is logged in system<\/p>\n
Production manager has all data available on safety device actions<\/p>\n
Production manager and machine operator discuss reason of frequent access. Tape causing problem can be replaced<\/p>\n
Machine running more efficiently with less maintenance required<\/p>\n
