Sumario:During Long Shutdown 1 the Beam Loss Monitoring system went through several hardware upgrades and general maintenance. Many elements of the system, starting from the tunnel detectors to the threshold-comparator cards were brought from their locations to the lab and refurbished. Almost 30% of the detectors will be reinstalled in new positions, optimizing system sensitivity to so called UFO losses. In order to tune the thresholds on cold magnets a series of quench tests has been performed during Run 1. An extensive analysis of these tests has been done leading to suggestions of a new sets of beam abort thresholds. The threshold setting strategy has been proposed. New tool to generate and set thresholds is being developed.
