For the CPM with electronik
The pin assignment of the connection cable for the serial interface:
Please, consider the following notes if you want to custom-specifically setup the optional
supplementary inputs/outputs:
Let only specialists carrying out the work since otherwise danger exists for your life!
The numbers in the circles refer to the figure of the controller printed circuit board (page 19).
To the 24 V outputs:
You can tap the voltage at the 9-pin Sub D connector
.
The switching outputs OPTO-5 and OPTO-6 are carried out with optical isolators with emitters
led outwards. They are available for signaling. These outputs are not disconnected in case of
Emergency-Off.
You must connect your loads against GND 24 V I/O (pins 6 to 9).
The maximum switching current should not exceed 15 mA!
The switching outputs are not short-circuit-protected.
