Safety Integrated SIRIUS 3TK2810-1 Speed Monitor
SIRIUS 3TK2810-1 Speed Monitor Speed, standstill and protective door monitoring safely combined Whether speed and standstill monitoring in machines and systems or protective door monitoring: The new safe SIRIUS 3TK2810-1 speed monitor from our safety relay range offers the perfect solution for all requirements. The SIRIUS 3TK2810-1 facilitates the simultaneous monitoring of three parameterizable limit values for standstill, setup speed and automatic speed. Furthermore, it features a complete protective door monitoring function with spring-actuated interlocking. This makes an additional evaluation device unnecessary, which not only results in minimized costs despite unchanged quality, but also supports considerable space savings. The new safety relay is suitable for all conventional sensors for speed monitoring. Safety Integrated www.siemens.com/sirius 1819.indd 1 12.10.10 17:43 One Device – Three Reliable Functions The SIRIUS 3TK2810-1 speed monitor combines three safety functions in a single device. It facilitates continuous standstill and speed monitoring in machines and systems. Easy parameterization and permanent diagnostics via the display support rapid troubleshooting at all times – often before faults lead to system downtimes. In addition to standstill and speed monitoring, the device comprises a monitoring function for protective doors with springactuated interlocking, which makes an additional evaluation device unnecessary. As a further major highlight, the SIRIUS 3TK2810-1 meets all requirements in accordance with SIL 3 and PL e. Safety functions which can be realized with the 3TK2810-1 speed monitor and additional circuitry Safe Torque Off – STO Safe disconnection of torque-generating energy which may lead to motor rotation. STO v t Safely Limited Speed – SLS Prevention of the motor’s exceedance of a specific speed limit. SLS v ∆t Safe Operating Stop – SOS Prevention of the motor’s deviation from its stop position by more than a specified value. The motor is controlled with full torque. t SOS s ∆t Safe Speed Monitor – SSM SSM supplies a safe output signal upon the drive’s shortfall of a defined speed limit value. t v 1 0 t 3TK2810-1 speed monitor Control supply voltage Screw-type connection Spring-loaded connection Order No. Order No. 24 V DC 3TK2810-1BA41 3TK2810-1BA42 110...240 V AC/DC 3TK2810-1KA41 3TK2810-1KA42 Application example Protective door closed L A2 T3 RF1R F2 15 25 14 A1 E0 3TK2810-1 RJ45 E1 24 T2 EA2P 2 13 T4 ST MAG Standstill U GND E1 A2 T3 RF1R F2 15 25 14 23 T1 Automatic / setup Standstill Automatic/setup E0 3TK2810-1 RJ45 23 T1 EA1P 1 S1 ST1 EA1P 1 Ein A1 T4 ST MAG 13 23 U GND E0 3TK2810-1 RJ45 E1 E1 E2 N T1 EA1 P1 U GND 24 T2 EA2 P2 ST2 S1 E1 A2 T3 RF1R F2 15 25 K6 N Gear wheel L M E1 13 A1 T4 ST MAG Open ST1 E2 Encoder On S1 Ein Door release Initiator (n2) Protective door closed ST2 Magnet L Motor Motor E2 Encoder (n1) Gear ratio gr=n1/n2=x/1 e. g. gr=5:1 Gear Shaft K5 14 K5 24 T2 EA2 P2 K6 N Speed and standstill monitoring By means of encoder Siemens AG Industry Sector Industry Automation Control Components and Systems Engineering P.O.Box 23 55 90713 FUERTH, GERMANY www.siemens.com/sirius 1819.indd 2 By means of two NPN or PNP proximity switches Subject to changes Order No.: E20001-A920-P305-X-7600 Dispo 27601 MI.CE.SG.SIXX.52.1.02 SB 10102.0 Printed in Germany © Siemens AG 2010 By means of encoder and one NPN or PNP proximity switch The information contained in this brochure merely comprises general descriptions or performance characteristics, which may not always be applicable in the described form to the specific application case or may change due to product advancement.
