SY-EPC-LPC LHC60A-08V Operation

Repair process

Standard Repair Standard Repair - Calibration Calibration - (Unknown Issue) (Unknown Issue)

Step	Item Status Before action	Who	Actions	Repair (ex:103466)
1	Broken unit Stored	CERN LPC/OMS	Analyse EPC-DB logbook & unit (RMLA). Repair.Problem = summarize info. Repair.Solution = proposed action.	> Problem > Solution > Validation
2	Broken unit Stored	CERN LPC/OMS	Create a snow ticket for repair to DSS.
3	Broken unit Under repair	DSS	Perform the repair following procedure. Give feedback to CERN (email) vs repair.
4	Repaired unit Not tested	CERN LPC/OMS	Update the logs. Repair.Solution = summarize DSS action.	> Problem > Solution > Validation
5	Repaired unit Not fully tested	CERN LPC/OMS	Perform the interlock (earth + leads) tests. Repair.Validation = Interlock results.	> Problem > Solution > Validation
6	Repaired unit Not fully tested	CERN LPC/OMS	Perform auto tests (cycles) (ROG How to?). Repair.Solution = Intermediate cycles results. (Templates exist to diagnose results if test fails).	> Problem > Solution > Validation
7	Functional unit Not calibrated	CERN LPC/OMS	Store unit with repaired not calibrated units.

Repair process of a known failure, profiting from existing procedure.
