Procedure for reset after an AUL trip in EHN1, H8b beamline

This procedure is for physics users or beam line operators (BE-EA-LE), who do not have a habilitation electrique. You can assist the competent services to turn the power back on, but you are not authorised to switch circuit breakers yourself.

How to tell if an AUL is pushed? Local power cut to H8b/GIF++ equipment only; general lighting in EHN1 remains on. If so…

Call the CCC TI desk on 72201. They do not receive any alarms from the AUL, but will be able to confirm if it is due to another cause. The operator may be able to assist directly, or can call in the EN/EL piquet service to help you.
