The European XFEL free-electron laser is under construction at the DESY. The driving engine of the superconducting accelerator will be 27 RF station. Each of an underground RF station consist from multi beam horizontal klystron which can provide up to 10MW of power at 1.3GHz. The XFEL should work continuously over 20 years with only 1 day per month for maintenance. In order to meet so demanding requirement lifetime of the MBK should be as long as possible. In the real operation the lifetime of tube can be thoroughly reduced by service conditions. To minimize the influence of service conditions to the klystrons lifetime the special fast protection system named as Klystron Lifetime Management System (KLM) has been developed, the main task of this system is to detect all events which can destroy the tube as quickly as possible, and then stop input power to the tube and send signal to stop HV pulse. The tube recovery procedure should depend on the kind of events has happened. KLM is based on the standard LLRF uTCA system for XFEL with additional DC channels. This article gives an overview of implementation of measurement and protection system installed at klystron test stand.
