9.9.  Connection of several devices in a switch chain

Important!

 

Ì

An AR switch chain may contain a maximum of 20 safety switches.

 

Ì

The example shows only an excerpt that is relevant for connection of the CES system. The exam-

ple illustrated here does not show complete system planning. The user is responsible for safe in-

tegration in the overall system. Detailed application examples can be found at www.euchner.com. 

Simply enter the order number in the search box. You will find all available connection examples for 

the device in Downloads.

The series connection is shown here based on the example of the version with plug connectors M12. The switches are con-

nected one behind the other with the aid of pre-assembled connection cables and Y-distributors. If a safety door is opened or 

if a fault occurs on one of the switches, the system shuts down the machine. A higher-level control system cannot, however, 

detect which safety guard is open or on which switch a fault has occurred with this connection technology. A special AR eval-

uation unit is required for this purpose (see chapter 

9.10. Information on operation on an AR evaluation unit on page 20

).

The series connection can also be realized via additional terminals in a control cabinet.
The safety outputs are permanently assigned to the respective safety inputs of the downstream switch. FO1A must be routed 

to FI1A and FO1B to FI1B. If the connections are interchanged (e.g. FO1A to FI1B), the device will switch to the fault state.
Always use the RST input in series connections. All switches in a chain can be reset at the same time with this reset input. 

To do this, a voltage of 24 V must be applied to the RST input for at least 3 seconds. If input RST is not used in your appli-

cation, it should be connected to 0 V.
Note the following on this aspect:

 

Ì

A common signal must be used for all switches in the chain. This can be a changeover switch or the output of a control 

system. A button is not suitable because the reset must always be connected to GND during operation (see switch S1 in 

Figure 4 on page 19

).

 

Ì

Reset must always be performed simultaneously for all switches of the chain.
