Drum to spindle failure

[BSavulis]

Hi all,
I have an Arrow 500 with CT control. This A.M. when we went to start the machine I could get the AXIS to align, and the spindle to orient. But the drum will not jog out to the spindle. I do not hear the solenoid firing at all. I checked the connectors, wiring, air fittings, pressure all looks good. I'm not sure the solenoid is getting the command. Any suggestions?

Thanks

Possibly a relay?

If you remove the air hoses of the valve block,taking note where they come from you should get a air rush when you engage the button, tool to spindel or park.If not you may want to check any fuses that may be in curcuit,I have had problems with the o'rings in the air control block they can leak air into the ajoining port and stop the cylinder from getting the correct air supply.
