No. Safety Door with Spring-Loaded Engagement in Category 4 acc. to EN 954-1 Automation Function Description of the functionality Interlocking devices with guard locking are mechanical or electrical devices which only enable operation of a machine if the door is closed and guard locked. Interlock and guard lock- ing is maintained until the risk of injury caused by hazardous machine functions or motions is excluded. This monitoring is usually performed by overspeed trips or standstill monitors. In this example, motion/stoppage of a machine is simulated by a NO contact. In this example, an actuator installed on the door moves form fit into a safety position switch with locked engagement. Dur- ing the potential hazard (machine in RUN), the actuator is held (and thus the door guard locked) by the fact that the voltage applied to a magnet in the safety position switch is removed. This type of interlock is referred to as spring-actuated lock. If the safety position switch fails, the safety function is main- tained by the hinge switch (also detects the opened safety door). This ensures that the requirements of the EN 954 : 1996 standard (Category 4) are met which pre- scribes redundant installation of all safety-relevant parts for position monitoring of the safeguard (here: Safety door). The voltage applied to the magnet is removed by resetting a failsafe digital output channel of the ET 200S; this channel is linked to the magnet. The other way, the magnet is supplied with voltage to be able to open the safety door by setting this output. The diagram below illustrates the concept of safety door mon- itoring: Note In this example, no real machine is controlled; the con- cept of a safety door monitoring with guard locking (on sensor side) is shown. If you want to additionally inte- grate a real machine or other actuators, you can of course use the parameters described in the correspond- ing STEP7 as basis. 3$ ; & & * +& %, +& , 4 %C $*5 5$9$* &* $ 4 %C$( +& , &*5 3 %$ 5*$ &4 3$ (&5& 4 ) ) 9 ()4$ @ @HA A ? $6)$ ? ? ? ? .$4$ $F # & & * +& %,J %4 $(F K&*5$ +& %,J %4 $(F *& &*5)*4 %C&*5@ F @HA A A %,&*$A @HA A ? ? ? ?
