SAFEMASTER S Standstill Monitor LH 5946 Sensorless Safety Standstill Detection The sensorless safety related Standstill Monitor LH 5946 of the SAFEMASTER S family recognizes direction-independent the standstill of motors without making use of additional external sensors like encoder or proximity switch.The Standstill Detection is directly achieved by monitoring the voltage at the motor connection terminals. Particularly when it comes to access protection, where regular intervention during production process is necessary, the sensorless Standstill Monitor LH 5946 can make use of its strengths. When there is no dangerous movement from the motor anymore the safety gate can be released within a very short time at detected standstill. Due to a variable adjustment of the response value and reaction time on the device, an individual adaption is possible. Compared to solutions with time-controlled unlocking of safety gates, maintenance and setup times can be minimized by use of the sensorless Standstill Monitor LH 5946 and thus productivity can be improved. Your advantages For safety applications up to cat. 4 / PL e / SIL 3 Fast reaction time Easy commissioning by means of screwdriver Easy retrofitting, as there is no connection of sensors 2-channel safety monitoring with extended error diagnosis Reductions of down time of machines and installations Combinations with safety lock SAFEMASTER STS available
