10.11. Information on operation on an AR evaluation unit
The devices can be operated on an AR evaluation unit.
Refer to the operating instructions for the relevant AR evaluation unit for more information.
Each of the devices occupies two monitoring outputs on the AR evaluation unit. The first monitoring output signals the guard
position (HIGH when the guard is closed). The second monitoring output signals the position of guard locking (HIGH when
guard locking is active).
NOTICE
Devices in the Extended version cannot be used with AR evaluation units.
10.12. 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 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
AR 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 pulse duration of your safety switch, refer to chapter
Ì
The following applies to single-channel control of guard locking:
The guard locking (IMM) and the control system must have the same ground.
Ì
For dual-channel control of the solenoid voltage by safe outputs of a control system, the following points must be ob-
served (see also
):
-If possible, switch off the pulsing of the outputs in the control system.
-Pulses up to a length of max. 5 ms are tolerated.
A detailed example of connecting and setting the parameters of the control system is available for many devices at

greater detail.
