8.10. Notes on operation with safe control systems
Please observe the following requirements for connection to safe control systems:
Ì Use a common power supply for the control system and the connected safety switches.
Ì A pulsed power supply must not be used for U
B
. Tap the supply voltage directly from the power supply unit. If the supply
voltage is connected to a terminal of a safe control system, this output must provide sufcient 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 safety switch, please refer to chapter 11.
Technical data on page 22.
A detailed example of connecting and setting the parameters of the control system is available for many devices at
