7.6.6 Connecting the solenoid of the proportional valve
▶ Install the solenoid cable separately from other cables, in particular the cables
of inductive position transducers. It is recommended that the solenoid cable be
shielded.
Recommended cable type: LiYCY 1.5 mm² for up to 50 m length; in the case of
longer cable routes, use a greater cable cross-section!

Attention: Connect shield to PE or ground;
not to 26a

7.6.7 Command values for pressure, swivel angle and power limitation
General notes:
• The command values for pressure and swivel angle are provided as analog
variables within the voltage range of 0…+10 V; this corresponds to 0…+100 % of
the physical range of values.
• Command values may only be passed on using appropriate contacts that are
suitable for currents <1 mA.
• The use of shielded cables is recommended (connect shield of the signal cable
to 26a).
Command value for power limitation
• The value for power limitation can either be provided internally by means of
potentiometer R3 or externally with a voltage level of 0...10 V.
• If the power limit value is to be provided externally, jumper J2 must always be
set in position 2-3 and potentiometer R3 (front side) must be turned to the left-
hand positive stop.
• If the external input is not used, connections 20c and 18c must always be
connected to 22a (M0).
