New Upgraded HY-T50 Power Supply Wiring Question

I’ve been trying to find the answer to this but must not be using the correct search words so have turned to the forum. In preparation for my new HY-T50 power I would like to confirm a couple of terminations as I’m not 100% certain that I have these correct. It’s the first three terminals on the HY-T50 (H, L & P) and “Lo” on the old K40 LPS to the Nano. Can that come from “L” on the HY-T50? Cheers.

P (protect) is high by default and the laser cannot fire unless it’s pulled to (i.e. connected to) G. So, you just connect your interlock switch to these two pins. Which way around doesn’t matter. If you also want to use a flow switch, put it in series with your interlock switch.

H is like L, but it works the other way around. It’s “active high” while L is “active low”. The H pin is unused in your case. You only need L (aka LO aka TL).

The minus of your 5V and 24V power supplies should be connected to G.

Thank you tomatsu; understood. The “H” had me guessing.
