Sensor not trigger signals

[thanhh019]

Hello,

I am working on a simulation that includes some actions happen on this conveyor. I want to test to change type of product. After declaring necessary frames and connect interface, the process is okay. However, then I realized that the Conveyor sensor 3 does not trigger any signals from the Sensor Boolean Signal. I do not know what problem is happening and how I can fix it. Please help me with this. Thank you very much in advance. You can find the simulation here:

Try this, All i did was detach the element and reattached it. I got the signal to trigger once i did this. I have the image as proof. Sometimes those default sensors attach to a different conveyor or can just bug out. Let me know if this is what you were trying to do.
