Laser Tube not working with lo x7

[a77an]

Hi i have a 60w laser tube and a the "lo x7" i connect all following this diagram viewtopic.php?f=55&t=2484 and when i turn on and press laser in the controller nothing happend, how can i test if the problem is configuration wiring or the tube is broken? i think with a meter i could test if some value is changing when i press laser but i do not know what value look for, i tryied whit every value and nothing changed, what may i be doing wrong? (sory for my bad english) tanks!

Something to check: On the laser PSU check to make sure you have the WP connection either tied to ground or on a flow switch.
