Electronic Overload System

0656 Electronic Overload System

The BROSA 0656 Electronic System used as an overload system for gantry, port, container, rotating tower and indoor cranes detects sensor signals such as loads, angles, heights and wind speed. These signals can be used to calculate the load to ensure shutdown of the system in an emergency. Furthermore,up to 4 load spectrum recorders with 10 load ranges each are available as options. These comply with guidelines FEM 9.511 and FEM 9.755. The overload system can be used in category 2 PLd according to EN 13849 or SIL2 according to EN 61508. The customer-specific data can optionally be conveniently read via a colour display with a diagonal of 4.3” or 7”. Furthermore, direct communication by the 0656 Electronic System with a higher-level crane PLC is possible via CANopen (Safety), PROFIBUS (PROFIsafe) or PROFINET (PROFIsafe). Data loggers and customer-specific interfaces can also be integrated on request. The 0656 Electronic System comes with the FlexLim (Safe) firmware installed, which makes it possible to parametrize defined applications on site very easily by the commissioning engineer via PC. Commissioning at BROSA can be ordered as an additional service. The 0656 Electronic System is supplied in a robust IP67/69k certified housing and can be mounted in the control cabinet as well as in exposed locations. Connection is possible for individual customers via a terminal strip or via modules or interfaces.

BSCT

The BROSA System Configurations Tool (BSCT) enables the individual configuration of applications on the PC. Various modules can be linked with each other in order to implement overload protection according to customer requirements. Amongst others, CAN, constants, curves, mathematical and logical operands, multiplexers, comparators and digital inputs and outputs are available. The BSCT enables the creation of application files which can then be transferred to the system via a serial interface (RS 232). The BSCT soft ware comes with a dongle
