The Trip Trap is an electronic instrument developed to solve a specific problem: Which interlock switch in a series string of switches opened first, and therefore shut down the system? For example, consider a process that sprays hot soapy water on a conveyor line. The engineers want the conveyor motor and water supply valve to shut down if the conveyor belt stops for any reason, or if the water pressure falls too low, or if the nozzle temperature gets too cold or too hot. A simple control circuit . There are four switches in an interlock chain, all closed during normal operation. Any one of these switches will open and shut down the system if its condition is met. But when one of them actually does shut the system down, you have a troubleshooting problem: Which one of them did it? You cannot determine the cause of shutdown by examining the switches, because they tend to dance around after shutdown. For example, if the nozzle gets too hot, the "hot nozzle" switch opens, shutting down the conveyor motor and water supply valve. The conveyor belt then coasts to a stop and the "belt stopped" switch opens. The "low pressure" switch also opens because the water supply valve is shut off. And in a few minutes the "hot nozzle" switch re-closes because the nozzle has cooled down. By the time a technician arrives, the original cause of the shutdown has disappeared. The current positions of the interlock switches are immaterial. The only thing the tech can do is restart the process and wait a few minutes. If nothing happens (often the case), he moves on to tilt at other windmills. What is needed are devices that watch the interlock s…
