Safety circuit for equipment moving linearly, includes controller providing signal as function of switching state, with voltage-increasing circuit coupled to conductive loop to supply control unit

摘要

A safety system (5) connected to the equipment includes a control unit (10) outputting a control signal. This is generated as a function of switching state. The safety system includes an electronic circuit increasing voltage (9). This is coupled to the conductive loop (4) and makes available a supply voltage for control unit, which arrives with the incoming signal
