If your waterflow-sensor has two wires, it will connect NO(Normaly Open) to COM (common) if the water flows.
That's the safe situation.
You have to connect those two wires to the WP on one side (doesn't matter which of the two) and to GND on the other side.
This can be done on the LPSU but better is to use the WP and GND connector on the controller (IMHO)
In the last case you also have to check the Water Protect Checkbox in LaserCad's Manufacturer Parameters (and save that to the controller)

Kees (or anyone else)

I'm at this point in my installation as well.

I haven't done anything with LaserCad yet. Everything I've done has been strictly through the DSP panel (LO-X7). I have wires coming from WP on Laser 1 as well as Laser 1 ground. There is a wire from Laser 1 ground to the neg terminal on the 24V DC power supply as well. I have set the Laser 1 WP to both closed and then to open in the manufacturer setup menu on the DSP. I reset the unit each time and confirmed that the changes were made. I can manually fire the laser regardless of the two wires being closed or open in either case. Shouldn't the laser be disabled when a WP condition is met ? I would think that this could be configured in the DSP rather than LaserCad.

maybe it's done in the new patch but YES you can/could fire the laser with all protection off (like the doorswitch)

This is why I had my door switch and flow switch wired in series into the WP circuit of the laser PSU.
