If you encounter problems with DTL:Tank3/Buncher2/Buncher3, try the following ... At the local RF console (north mezzanine, west console): 1) Make note of the DTL:Tank3/Buncher2/Buncher3 tuner position readbacks. When working correctly you should see noise. If the readbacks are frozen, you're seeing the fault described below. 2) Close and then re-open the following RF control programs: buncher2, buncher3, dtl3, auxx1, and auxx2. 3) Check the tuner position readbacks again. If you see noise, try starting the cavities. If the readbacks are still frozen, repeat step 2. If the second attempt doesn't work, reboot the RF console. Jon
