Wiring the RDC6432 to the LSU - No firing

CO2 Laser Cutting & Engraving Laser Power Supply
1

Hey there.

I have just come to the exciting part of my laserbuild where I should be able to fire the laser.

I have followed the diagrams i the RDC6432G manual connecting wp to a flow sensor, and the ext run to the door - they both say error when activated. But when I push the test button or the pulse on the screen, nothing happens. if I run a testcut, the same. No firing… How can I test if the powersupply (cloudray 40w 115v/230v) does indeed work???

I have connected:
AC
AC Mains input
Earthing(ground)
Anode through AMeter
(the green led is on)

Then there is a connection from
the controller PWM to IN on the LPSU
and the (minus/common ground)from controller is connected between the
and then the l-on to K+ on the LPSU

Any help appriciated!!

I actually found the solution on my own - so for others having this issue!

Remenber to short the WP to ground on the LPSU for controller firing!
