The stopped-motion detector is designed to be used with locking switches (light, medium, or heavy duty) that are applied to machines or robots with an inconsistent or variable coastdown time.
The stopped-motion detector has an on-delay that can be adjusted between 0.1 second and 40 minutes through a series of four time ranges. It also uses two independent proximity sensors and monitors two moving metal parts of the machine or robot. This means it can detect when hazardous motion has stopped. Should either sensor detect motion, the machine guard will remain locked. This capability is essential on machines which do not have a consistent coastdown time. |
