6 Operating principle, references Preventa safety modules Type XPSAV For Emergency stop and switch monitoring Operating principle Safety modules XPSAV are used for monitoring Emergency stop circuits conforming to standards EN/ISO 13850 and EN/IEC 60204-1 and also meet the safety requirements for the electrical monitoring of switches in protection devices conforming to standard EN/ISO 14119. They provide protective for both the machine operator and the machine by immediately stopping the dangerous movement on receipt of a stop instruction from the operator, or on detection of a fault in the safety circuit itself. In addition to the stop category 0 instantaneous opening safety outputs (3 for XPSAV ), the modules incorporate stop category 1 time delay outputs (3 for XPSAV ) which allow for controlled deceleration of the motor components until a complete stop is achieved (for example, motor braking by variable speed drive). At the end of the preset delay, the supply is disconnected by opening the time delay output circuits. b The time delay of the 3 output circuits is adjustable, in 15 preset values, between 0 and 300 seconds using selector buttons. b Module XPSAV also incorporates 3 solid-state signalling outputs for signalling to the process PLC. b To aid diagnostics, the modules have LEDs which provide information on the monitoring circuit status. b The Start button monitoring function is configurable depending on the wiring.
