8.7. Notes on operation with safe control systems
Observe the following guidelines for connection to safe control systems:
Ì
Use a common power supply for the control system and the connected key adapters.
Ì
The following applies to BP devices:
The device tolerates voltage interruptions at UB up to 5 ms in duration, provided
that the time between two voltage interruptions is at least 500 ms.
Ì
The following applies to BR devices:
A pulsed power supply must not be used for UB. Tap the supply voltage directly
from the power supply unit. If the power supply is connected to a terminal of a safe control system, this output must
provide sufficient electrical current.
Ì
Always connect inputs FI1A and FI1B directly to a power supply unit or to outputs FO1A and FO1B of another EUCHNER
BR device (series connection). Pulsed signals must not be present at inputs FI1A and FI1B.
Ì
The safety outputs FO1A and FO1B can be connected to the safe inputs of a control system. Prerequisite: The input must
be suitable for pulsed safety signals (OSSD signals, e.g. from light grids). The control system must tolerate test pulses on
the input signals. This normally can be set up by parameter assignment in the control system. Observe the notes of the
control system manufacturer. For the test pulse duration of your key adapter, see chapter
A detailed example of connecting and setting the parameters of the control system is available for many devices at

. The features of the respective device are dealt with there in
greater detail.
8.8. Connection without and with IO-Link communication
8.8.1. Connection without IO-Link communication
Only the safety and monitoring outputs are switched with this connection method.
With a series connection, the safety signals are looped through from device to device.
8.8.2. Connection with IO-Link communication
If, in addition to the safety function, detailed monitoring and diagnostic data are to be processed, a BR/IO-Link Gateway is
required.
To poll the communication data from the connected device, communication connection C is routed to the BR/IO-Link Gateway.
You will find further information in the operating instructions for your BR/IO-Link Gateway.
