Subject: TP3 RP failure 

Disconcerting because those tip seals were just replaced [15417]. Maybe they were just defective, but if there is a more serious problem with the pump, there is a spare Varian roughing pump (the old TP2 dry pump) sitting at the X-end.

I reset the interlock error to unfreeze the vac controls (leaving V5 closed).

So the conclusion is that RP for TP3 has failed. Presumably, the tip-seal needs to be replaced.

Right now TP3 was turned off and is ready for the tip-seal replacement. V5 was closed since the watchdog tripped.
