2 Hydraulic Fluid
Mineral oil based hydraulic fluid according to DIN 51524,
parts 1 to 3, (ISO 11158).
Other hydraulic fluids on request.
Viscosity: 5...400 mm²/s, recommended 15...45 mm²/s.
Temperature range: Ambient T
fluid T –20...80 °C (68...178°F).
F
Class of cleanliness
according to ISO 4406:1999
Class, at least
Class, for longer life
The cleanliness of the hydraulic fluid greatly influences the
functional safety and the wear and tear. In order to avoid mal-
functions and increased wear and tear, we recommend filtrat-
ing the hydraulic fluid accordingly.
Flushing instruction: Use of flushing plates or flushing valves
according to the machine manufacturer's instructions.
3 Installation
Compare model number and type with that specified on hy-
draulic schematic. The valve can be mounted in any position,
fixed or movable.
Mounting surface:
(< 0.01 mm (0.00004 in) over 100 mm (3.94 in)) and finish
(R < 0.8 µm). Care must be taken to ensure that contamina-
a
tion does not enter the hydraulic system, all work areas must
be clean of surface or air-borne contamination.
Mounting: Socket head screws (grade 10.9) according to
EN ISO 4762, torque from inside to outside (not with D671) di-
agonally alternating.

4 Pilot Mode and Maximum Pressures
Pilot mode: Pay attention to the hydraulic connection scheme
and to the mounting pattern of the hydraulic manifold. Pay at-
tention to the hydraulic schematic on the valve nameplate and
to the type designation defining the pilot mode.

5 Electrical Connection

Electrical safety: The protective conductor connection is con-
nected to the electronics housing or valve body. The insulation
materials employed are designed for use in the safety extra-
low voltage range. The field bus circuit connections are only
functionally galvanically isolated from the other connected cir-
cuits.
To comply with safety regulations requires isolation from the
mains according to EN 61558-1 and EN 61558-2-6 and limiting
all voltages according to EN 60204-1. We recommend using
SELV/PELV power supplies.
Rated signal: See nameplate.

Valve phasing: A positive signal (D–E) for 6+PE connector or
(4–5) for 11+PE connector causes valve opening PA.
Connector wiring: See wiring schematic tag attached to elec-
tronics housing, or refer to the catalog or the installation draw-
ing.
Connection: Signal lines shielded, shielding connected at
both ends and additionally connected to reference potential
(0 V) at the control side (to improve EMC). Connect the protec-
tive conductor.
Observe technical note TN 353.
6 Hydraulic System Start Up
Pay attention to the pressure setting, the venting instructions,
the fail-safe functions and the alarm messages!
7 Null Adjustment
WARNING
Unsafe state of the machine due to wrong posi-
tion of the valve's spool.
A wrong position of the valve's spool may result in
undefined sequences of motion.
 With valves with fail-safe function, the null position
must not be altered.
The null adjustment of the valve and further parameterizations
can be done via the field bus.
