Main Failure

Issue

Behavior of the system in case of a main failure.

LTQ XL Ion Trap Model

Understanding the power failure:

A main power failure has the same consequence as switching off via the main power switch.
If the power is available again, the system starts up automatically: the pumps are switched on and the instrument is pumped down.
If the system has been vented during the mains failure, it is necessary to bake out the system to obtain the operating vacuum.
It is not possible to check whether the system was vented.
The log file of the data system indicates a reboot of the system. In case of frequent but short power failures we recommend installing an uninterruptible power supply (UPS).
If main power failures occur frequently while the system is not attended (e.g. in the night), we recommend installing a power fail detector.

Note: The intentional venting of the system is performed with the vent valve of the linear ion trap.
