  • Page 5: Description

    Description Description The Sensor Sewi KNX L-Pr for the KNX building bus system captures brightness and the presence of persons in rooms. The brightness value measured can be used for the control of limit-dependent switching outputs. States can be linked via AND logic gates and OR logic gates.

  • Page 6: Safety And Use Instructions

    • Take the device or system out of service and secure it against unintentional use, if it can be assumed, that risk-free operation is no longer guaranteed. Sensor Sewi KNX L-Pr • Version: 25.01.2021 • Technical Changes and Errors excepted.

  • Page 7: Installation

    Elsner Elektronik is not liable for any changes in norms and standards which may occur after publication of these operating instructions.

  • Page 8: Connection

    The Sensor Sewi KNX L-Pr is surface-mounted but at the same time can also be screwed to a flush-mounted socket. If the Sensor Sewi KNX L-Pr is installed on a flush-mounted socket, it must not con- tain any wiring with 230 V.
