ABSTRACT:
In an apparatus for safety monitoring of protective arrangements with normal or enhanced safeguard for machinery performing multiple-axis rotations with shutoff contactors in the power supply section of the machine and an external monitoring circuit for safety hoods, contact, and manual permission for limited rotation, it is proposed that a power supply unit and a control unit, each in separate subhousings, be arranged in a basic device, with a plug contact connection being provided between the two that is separable and serves for interposed series connection of further supplementary monitoring units, with each monitoring unit monitoring certain shaft circuits of the target system and delivering its output signals in parallel on continuous tie lines guided via the respective plug contact means to the power supply unit, which activates shutoff contactors located in the power section of the target system via output relays.
