11.9. Connection of a single MGBS-AR
If a single MGBS-AR is used, connect the device as shown in Figure 5 . The monitoring outputs can be routed to a control
system.
The locking modules can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 s.
The RST input must be connected to 0 V if it is not used.
WARNING
If there is a mistake, loss of the safety function due to incorrect connection.
Ì To ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.
Important!
Ì The example shows only an excerpt that is relevant for the connection of the MGBS system.
The example illustrated here does not show complete system planning. The user is responsi-
ble for safe integration into the overall system. Detailed application examples can be found at
www.euchner.com. Simply enter the order number of your locking module in the search box. All
available connection examples for the device can be found in “Downloads.”

11.10. Connection of several MGBS-AR in a switch chain
Important!
Ì An AR switch chain may contain a maximum of 20 locking modules.
Ì The example shows only an excerpt that is relevant for the connection of the MGBS system.
The example illustrated here does not show complete system planning. The user is responsi-
ble for safe integration into the overall system. Detailed application examples can be found at
www.euchner.com. Simply enter the order number of your locking module in the search box. You
will find all available connection examples for the device in Downloads.
Ì For information about the safety assessment for AR switch chains, see chapter 3. Description of
the safety function on page 6 .
The series connection is shown here based on the example of the version with plug connectors 2 x M12. The series connection
of the version with plug connector RC18 has similar behavior, but is realized using additional terminals in a control cabinet.
The locking modules in the version with plug connectors 2 x M12 are connected one after the other with the aid of pre-as-
sembled connection cables and Y-distributors. If a guard is opened or if a fault occurs on one of the locking modules, the
system shuts down the machine. A higher-level control system cannot, however, detect which guard is open or on which
