  • General information on safety relays
    manipulation of the reset button is prevented The break contact in the reset circuit ensures that the safety relay does not reset until the button desensitises In this way for example dangerous situations caused by taping something on the bottom of the button will be prevented Safety functions and safety circuits Skriv ut bild A machine s safety circuits must be implemented in such a way that any possible defects do not affect safety or in other words that in the event of a defect happening in the safety circuit the safety circuit will go into a safe state When relays are used in safety circuits they must be duplicated and cyclically controlled as well as being equipped with forced contacts Here duplication means that if a situation is encountered where a defect exists safety functions will be preserved by duplicated operations without causing a dangerous defect By controlling is meant that the defect is detected whereupon the machine cannot be restarted until the defect is corrected All Duelco safety relays have these functions Control and detection of defects with a 2 channel safety relay 2 channel operation means that the safety relay has two safety circuits for example T11 T12 and T21 T22 which must be off before the safety relay can be activated reset True 2 channel operation also means that a short circuit between two channels safety circuits will cause an immediate stop signal in this way the accumulation of numerous errors can be prevented After every shutdown each safety relay must open and close before the safety relay is again ready for operation active Defect 1 A short circuit has been detected between emergency stop channels which the PTC fuse notices and the safety relay causes a stop The safety relay can be reset only when the defect is corrected Defect 2 With the aid of the duplication the emergency stop circuit controls operation The defective channel safety circuit is detected by the next start stop in the cycle and the safety relay cannot be started until the defect is corrected Emergency stop NST 4 2002 2 2004 Skriv ut bild Complies with standard EN 60204 1 A single defect the first defect must not cause a dangerous situation The defect must not remain in the system causing a dangerous situation with the next defect second defect Outputs Safety contacs In Duelco safety relays safety outputs are implemented with forced relays In a forced relay the contacts are mechanically connected to one another in this way it is ensured that NC and NO contacts will never close at the same time If the NC contact is welded shut the NO contact is unable to close when the coil is energized In the same way the NC contact is unable to close when voltages are removed from the coil at the same time that the NO contact has been welded closed In this way the defect is detected Correct operation Erroneous operation Contact A has been welded

  • General information on 2-handed controls
    and there must be control which can be achieved using a safety relay 2 handed control relay Definition of a 2 hand control device SFS EN574 A device that requires at least simultaneous effect on control using the hands so that while in dangerous environments it will be possible to start and maintain each function of a machine and then realise a given protection only for the user of the control device Skriv ut bild 1 Push buttons input signals 2 Contacts signal converter 3 A 2 hand controller 4 Control unit activating unit and signal processors a 2 hand control relay 5 A complete 2 hand control device 6 Outputs output signals Technical and functional specifications Activation of the 2 hand control device must not be possible with only one button Activation of a 2 hand control device may be possible only by pressing two separate buttons max within 0 5s of each other A 2 hand control device must not make it possible for a machine to start unless both buttons have returned to the resting state A 2 hand control device must have self diagnosis i e if the 2 hand relay develops a defect starting the machine must be impossible Physical requirements of a 2 handed control Skriv ut bild The push buttons must have been ergonomically constructed and must be easy to use The push buttons must be located at least 260mm apart so that it will be impossible to activate both buttons with one hand The push buttons must be shielded from the top and the side so that they cannot be activated with an object 260mm long such as a pipe Nor can it be possible to activate the push buttons with an object the overall length of which is 550mm 300mm forearm and 250mm palm See picture The distance between the 2 hand control and the dangerous machine must be sufficient so that in using the 2 hand control the elbow does not extend into dangerous places Similarly if there is an effort to activate the second button with the elbow the distance must be sufficient so that the hand does not reach dangerous places A 2 hand control must be located at a height of at least 1100mm from the floor or work level so that activation of the buttons is not possible by using some other body part e g a foot Push buttons must be mechanically shielded as in a 2 hand controller PCB so that their activation according to the instructions with sized objects is not possible Test cone Skriv ut bild The push buttons are separated by shields which limit exit from the operating side and also the backside in such a way that the elbow cannot affect the push buttons from the operating side with the tip of the illustrated test cone The measurements of the test cone must be as shown in the picture More about 2 hand controllers in standard SFS EN 574 EN
