Multi-pole Connection 10.5.2.
Internal cabling work is not required for models with multi-pole connection, which makes installation and start-up
on site considerably easier and quicker, reducing the risk of leaks. However, you will require the correspondingly
assembled cable sets with the following pin assignments:
input and output signals to the higher-level control (plc):
12-pole circular plug-in connector M12 x 0.75 - male (acc. to IEC 61076-2-101)
10
Pin 9 - Y3
Pin 8 - Y2

Pin 6 - S4 out
Pin 7 - Y1
Pin 1 - 24 V
Pin 5 - S3 out
Pin 4 - S2 out
11
Pin 3 - S1 out Pin 2 - GND
The center pins
(10, 11 and 12)
