      load monitoring: VKS-0151 The load monitoring VKS-0151 is special designed for the overload control changing forces as soon as for reliable deactivation of cranes or lifting units on identifivation an overload. Internal monitoring and checking routines admit the handling of the system in regions which make demands on definite interruption processes at overload. VKS-0151 has available: · 2 measuring channels independent of each other (one or two load sensors) · electronic: evaluation of measured values and generation of two interruption tracks · firmware: evaluation of measured values, of the state of sensor, of the automatic checking of functional components including of sensor(s) and for the generation of switch signals · internal control unit and display for service and startup optional add-on: · external display of operating parameters (service unit VHB-0250) · RS232 interface (tests / startup functions & update of firmware) · combined USB/SD card interface (communication tasks & storage of measured values) · bluetooth communication modul for networking several VKS-0151 units (load summation) The system controls the measured value of the sensors periodical. The loads can be evaluated separately or as summation according to configuration and firmware version. These resultant loads are compared to two thresholds. Two trimmer potentiometer are into the electronic part for this which output the values for two thresholds independent of each other. The result of the comparison is indicated outwards by dint of two interruption tracks. The firmware cuts off the interruption tracks in addition with occured malfunctions of unit or sensor. download general data sheet: VKS-0151 |
