- Xevo TQ-S crash vented and is unable to pump down
- Xevo TQ-S
The scroll pump/rotary pump has failed.
FIX or WORKAROUND
Replace the faulty scroll pump/rotary pump.
With scroll pumps, be certain to unplug the power cord for at least five minutes, and then try pumping again; there is sometimes a logic in the electronics of the pump that causes a latch. Also, be certain that the small screw on the black connector at the bottom of the pump is screwed on fully. There is a thermocouple sensor connection here, and if it is not connected, the pump will not turn on.
