Using the system
Safety circuits
The safety modules of the MSI 100/200 system can be flexibly configured. For the creation of
the safety logic, the system is equipped with safe function blocks. You can thereby use the
MSI 100/200 system to implement various safety functions in different safety circuits. Just
some of the most important options are listed below:
–
E-Stop monitoring
–
Safety door monitoring (with and without locking device)
–
Two-hand control units (types II and III)
–
External device monitoring (EDM)
–
Monitoring and checking electro-sensitive protective equipment
–
Operating mode selector switch (evaluation of an operating mode selector switch and an
enabling switch)
–
Muting applications (light grid monitoring with parallel muting)
Application examples:
In the help system of the MSIsafesoft configuration software, you can find application exam-
ples for the safe function blocks with typical application for each function block.
The safety logic configured in the configuration software as well as the wiring of the safety
modules and the safe extension modules is displayed in the form of schematic views.
The online help also includes typical signal sequence diagrams, which illustrate the behavior
of each function block.
The following application examples are included in the online help for the function blocks:
–
Single-channel and two-channel E-Stop circuits
–
Single-channel and two-channel safety door monitoring, with and without locking
–
Operating mode selection with locking of the set operating mode and manual operating
mode acknowledgment
–
Evaluation of a three-position enabling switch with confirmation of the selected safe
operating mode
–
Parallel muting with two sensors
–
Evaluation of a light curtain connected via a single channel
–
Type II and type III two-hand control devices
