    SLCT* and SLCT*/35 safety light curtains Installation Installation Planning and Preparation Warning! Danger to life due to ineffective protective equipment Improper or incorrect alignment, fixing, and connection to machine control can impair the effectiveness of the protective function. Note the applicable standards, guidelines, and legal regulations for the equipment of machine and plants with protective equipment.
  • Page 15 SLCT* and SLCT*/35 safety light curtains Installation To comply with the necessary distances in the event that the protection field spreads, please refer to Table 1 of ISO/EN 13855 to check the minimum distance for a vertically positioned protection field. If you read the value 0 from the table, you can determine the minimum distance with the following formula: S = K x T + C Where, for a protection field aligned vertically to the hazardous area:...

    SLCT* and SLCT*/35 safety light curtains Installation Reflection Danger! Danger to life due to reflection If you do not comply with the minimum distances, objects or persons cannot be safely detected in the beams of the protective equipment. When aligning the protective equipment, ensure that the minimum distance to reflective objects or surfaces on all sides of the protection field is observed.

  • Page 22: Connection And Operating Mode Setting

    SLCT* and SLCT*/35 safety light curtains Installation Danger! Danger to life due to indirect dispersion of light during operation below the specific minimum range If you operate the protective equipment below its specified minimum range, this can lead to reflection caused by reflective or dispersive objects outside the specified minimum distances.

  • Page 23: Signal Outputs On The Receiver Unit

    SLCT* and SLCT*/35 safety light curtains Installation The function can be activated or deactivated at the 8 pin connector of the receiver SLCT. The two feedback contacts on the external switching elements must be placed between 24 VDC and the relay monitor input in order to activate the relay monitor. The relay monitor function is deactivated if the relay monitor input is bridged with the status/select output.

  • Page 24: Signal Inputs On The Transmitter Unit

    SLCT* and SLCT*/35 safety light curtains Installation 4.4.2 Signal Inputs on the Transmitter Unit Test input Connect the test input to 24 VDC via an NC contact. The test function is triggered by opening the contact. Note! During operation without a startup/restart interlock, the test time must be limited to 150 ms.

  • Page 25: Signal Inputs On The Receiver Unit

    SLCT* and SLCT*/35 safety light curtains Installation After the supply voltage is switched on, the transmitter or receiver unit selects mode A or mode B, depending on the applied voltage. Note! Make sure that the transmitter unit and receiver unit are operating in the same mode.
  • Page 26 SLCT* and SLCT*/35 safety light curtains Installation Relay monitor input Auxiliary contacts on switching elements connected downstream of the OSSDs can be connected to the relay monitor input.
