Bi-Monthly checked the dust monitor vacuum pumps. 

   Both end stations were fine. Vacuum pressures were correct and the temperatures were between 100 and 130f,  

   Found the CS vacuum pump shut down. Recycled the power switch and the pump restarted. There was a good blast of carbon dust out of the exhaust. This is the second time this pump has shutdown. Will continue to monitor the pump throughout the day. Plan is to take it off line and rebuild the pump section. I have the repair kit in hand.
