Emergency stop shutdown and protective door monitoring up to SIL 3 or PL e via ET 200ecoPN and F-CPU

  • Entry
  • Associated product(s)
Protective doors are frequently used to fence off danger zones. These are monitored for position and, if necessary, the area from which the hazard emanates is switched off. An emergency stop command device is additionally monitored for shutting down the machine in an emergency. To record these two safety functions in the IP67 environment a fail-safe version of an ET 200eco PN is used.


Emergency stop shutdown and protective door monitoring up to SIL 3 or PL e via ET 200ecoPN and F-CPU

Operating principle

The emergency stop command device is directly connected to a fail-safe input socket (F-DI) of the ET 200eco PN by means of an M12 cable. The two position switches are joined by means of a special M12 Y-cable and likewise connected directly to an individual F-DI of the ET 200eco PN. The fail-safe controller (F-CPU) monitors the two safety switches as well as the emergency stop command device on two channels. When the emergency stop command device is actuated or the protective door is opened, the fail-safe controller switches the power contactors off in a safety-related way. If the door is closed, the emergency stop command device is unlatched and the feedback circuit is closed, the Start button can be used to switch on again.
