Relay controller

Hello everyone , new here I have a ginmitsu 4040 pro max I just got the I Matic relay controller to power on the spindle and the vacum with the cnc and its not working for me, does anyone know if I have to fix any setting in Gsender to make it work?the relay hooks up into the laser controller on the cnc I tried to check that on t\gsender but still no luck, any suggestions?

Thank You
