7.6
Cut off the brown and the green cores on the adapter line for the sensor connection
1.
7.7
Crimp the wire-end ferrule (e) on to the white and yellow cores of the actuator line.
7.8
Connect the adapter line for the sensor connection 1 to an external floating contact
of a measuring device, if necessary use an extension cable.
7.9
Connect the adapter line to the sensor connection 1 (G).
Connecting the actuators
7.10 Squeeze the wire-end ferrules (e) onto the actuator lines (d).
7.11 Connect the actuator lines to the actuators (e. g. solenoid valve).
Important!
Pin assignment table must be observed.
7.12 Connect the actuator lines (d) to the actuator distributor (L).
