9 CAM interface
There is an electrically isolated, bi-directional interface available for communication with the CAM device�
en
Via two inputs and two outputs, 4 commands can be received from the extraction unit or 4 status informa-
tion can be sent to the CAM machine�

9.1.1 Outputs (Out1 / Out2)
The output signals are potential-free switch outputs, in an optocou-
pler, with a 150 Ohm series resistor�
Please see chapter 8, Technical Data, for the maximum pull-up volt-
age (U) and the maximum permissible switching current (I)�
The external pull-up resistor (R) must be set so that the maximum
permissible switching current ( I) is not exceeded�
9.1.2 Inputs (In1 / In2)
The input signals go to the optocoupler LEDs. See chapter 8, Technical Data, for the specified input volt-
ages of the two signal levels „low" / "high"�
