Modular FRL Series Airplus Safeline Please note: the safety valve is not sufficient alone to guarantee the safety function. Its setup requires the use of a monitoring device. In this setup, the SIEMENS 3SK2112 monitoring device has been indicated, activated by an S2 start / reset pushbutton, blocked by an S1 emergency shutdown key. Said monitoring device, by means of the readings of the sensors placed inside the double valve, operates the activation of the valve itself. The preliminary estimate and the final verification of the achieved PL are the responsibility of the designer of the part of the system dedicated to providin the safety function. Setup suggestions • The double stop pushbutton is connected to clamps T1-F-IN1 and T2-F-IN2 of 3SK2112. • The start /reset pushbutton is connected between +24 V and the F-IN10 clamp of 3SK2112. The double valve, for notation simplicity, is indicated as consisting of 2 valves: EV1 and Ev2 EV1 • The valve is supplied between 0 V (Pin 3 of the supply connector) and the F-Q1 clamp of 3SK2112 (Pin 2 of the supply connector). • The HALL effect sensor is supplied between 0 V (Pin 3 of the supply connector) and 24 V (Pin 1 of the supply connector). • The HALL effect sensor is attached (Pin 4 of the supply connector) to the monitoring device’s F-IN3 clamp. EV2 • The valve is supplied between 0 V (Pin 3 of the supply connector) and the F-Q2 clamp of 3SK2112 (Pin 2 of the supply connector). • The HALL effect sensor is supplied between 0 V (Pin 3 of the supply connector) and 24 V (Pin 1 of the supply connector). • The HALL effect sensor is attached (Pin 4 of the supply connector) to the monitoring device’s F-IN4 clamp. 2 F-IN6 F-IN8 T2 F-IN2 F-IN5 F-IN7 F-IN9 T1 F-IN1 QM1 F-IN4 F-Q2 F-IN3 A2- BROWN 3 BLUE 1 3SK2112 BLACK G EV 1 S2 F-Q1 BLUE BROWN A1+ S1 F-IN10 The circuit diagram of the suggested configuration is provided. 24 VDC 0 VDC BLACK G EV 2 2 1 3 Analysis of malfunctions The diagnostic system (monitoring device plus sensors) has the purpose of verifying the appearance of malfunctions within the valves, which undermine the safety function. In particular, the monitoring device must be appropriately programmed to avoid the system’s reset by means of S2 when both coils are de-energised and at least one sensor remains in an OFF position.
