CMSX-...-C-U-F1-...
Note
If connected in accordance with Fig. 17, the disconnection of the circuits of the operat­
ing voltage supply and of the load voltage for outputs is cancelled.
Setpoint value of inputs è Pin 1 ... 4 (setpoint value of the controlled variable)
The setpoint value can be specified as an external voltage of current signal. Both setpoint inputs can be
connected. But in all cases, only one of the two setpoint values is active – dependent on the paramet­
erisation (factory setting è Tab. 16).
Output actual value è Pin 7, 8 (actual value of the controlled variable)
The position actual value (valve position VP) is made available for higher-order systems as a current
signal (it is influenced through the Open parameter è Tab. 16).
Digital outputs; ALARM, D-OUT1, D-OUT2 è Pin 10, 11, 12 and pin 14
The ALARM output delivers high level if the maximum positioning time is exceeded at initialization.
The outputs D-OUT1 and D-OUT2 can be wired as PNP or NPN outputs. Their behaviour can be con­
figured (è Tab. 16). To operate the outputs as PNP outputs, the load must be connected between the
output and 0 V (pin 14). The following diagram shows as an example the connection of the digital out­
puts when PNP outputs are used.

Fig. 18 Connection of digital outputs as PNP outputs – example
To operate the outputs D-OUT1 and D-Out2 as NPN outputs, the load must be connected between the
output and 24 V (pin 13).
