Gearmotors/Explosion-Protected Gearmotors/Helical Gearmotors R10 Industrial Gear Units: Bucket Elevator Drives of the MC... / M... Series2.3 Mandatory supplementary equipmentSpeed monitoring For safety reasons, the drive combinati on for bucket elevators must be equipped withspeed monitoring. SEW-EURODRIVE offers a complete solution consisting of encoder and speed monitorfor this purpose.The speed of the overrunning clutch is dete cted in a contactless manner via trigger cam[1] and inductive encoder [2]. The speed moni tor [3] compares the pulses with a presetreference speed.The output relay trips (optiona lly NC contact or NO contact) when thepreset speed is exceeded (e.g . due to a malfunction of t he overrunning clutch). Thisway, overspeed at the auxiliary drive is prevented.52043AXX[1] Trigger cam[2] Inductive encoder [3] Speed monitorSpeed monitor W Reference speed, starting bypass and switch ing hysteresis can be set at the speedmonitor. Enclosure: IP 40 (IP 20 terminals) Operating voltage: AC 110 V (part number 106 7
