Mist coolant output not working

Just installed a Fog Buster on my Dyna Mill with a Ajax(Centroid) control. I have hooked up a solenoid valve to the mist coolant output on the main board. When machine is up and running I try to actuate the mist coolant manually or through MDI(M07) and I get nothing the led on the panel does not light and I do not get a return on the screen that says mist coolant on. I have checked parameter 8 and it is set to (2) both coolant, is there something else I need to change or has anyone else had this issue. Flood coolant works fine in manual and MDI.

Thanks !

It sounds like the mist coolant logic may be missing from your PLC program. Impossible to tell, though, without seeing the PLC program.
