For more details see the Clink II FCU Manual version 4.0 and higher. As a consequence for the SCU the analog input channel is no longer present.The description of this analog input has been...

  • Page 11: Safety Instructions

    Failure to comply may result in personal injury and/or equipment damage. Warning One of the strong features of Clink II is the possibility to replace units while keeping the Clink II system operational. The replacement of Clink II parts should always be reported and executed according to local safety procedures.
