2 Operating principle, characteristics Preventa safety modules type Operating principle Safety modules meet the requirements of Performance Level PL e/category 4 conforming to standard EN/ISO They are used for: b Monitoring Emergency stop circuits conforming to standards EN/ISO 385 and EN b Electrical monitoring of switches activated by protection devices, with optional selection of synchronisation time between signals. b Monitoring 4-wire sensing mats or edges. b Monitoring type 4 light curtains conforming to EN/IEC which have solidstate safety outputs with test function (light curtains XUS L). Housed in a compact enclosure, the modules have 3 safety outputs, a relay signalling output and 4 solid-state signalling outputs for signalling to the process PLC. Preventa safety modules ppppp incorporate removable terminal blocks, thus optimising machine maintenance. To aid diagnostics, the modules have 4 LEDs on the front face which provide information on the monitoring circuit status. The button monitoring function is con gurable depending on the wiring.
