NOTICE
Damage due to dirt, moisture and ozone/UV effects
• Storage outside or under the wrong climatic conditions can
cause corrosion and other damage to the valve. Conden-
sation due to temperature fluctuations can result in elec-
tronic malfunctions.
 In the case of intermediate storage, observe the follow-
ing storage conditions:
• Recommended ambient temperature: +15 to +25 °C
(+60 to +78 °F), permissible temperature: –40 to
+80 °C (–40 to +176 °F), temperature fluctuation:
< 10 °C (18 °F)
• Relative humidity: < 65 % not condensing
• Ensure there are minimal vibration and shock where
valves are stored
 Following transport or storage, wait until the valves have
reached ambient temperature before starting up.
• Dirt and moisture can enter the valve through openings
and cause damage. Seals can be damaged due to the
effects of ozone and UV.
 During storage and transport, seal connectors with dust
protection caps and install the shipping plate on the
mounting surface.
 Remove dust protection caps and shipping plate only
shortly before mounting the valves and keep packaging
materials for future storage and transport.
 Seal with protection caps any valve connectors that are
not used in operation (without mating connector).
Compare model number and type with that specified on hy-
draulic schematic. The valve can be mounted in any position,
fixed or movable. The venting screw has to point upwards.
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 diagonally alternating.

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.
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.
External fuse per valve: 1.6 A time lag
Valve phasing: A positive signal (D–E) 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
and the alarm messages!
7 Venting
Hydraulic fluid squirting out
Hydraulic fluid squirting out under high pressure or
parts falling off can cause serious personal injuries,
burns and fires.
 Only vent the valve and the actuator at a low sys-
 Carefully open the venting screw by approx. one
8 Null Adjustment (Pressure)
Remove the locking screw with sealing ring from the cover of
the electronics housing to access the null adjustment potenti-
ometer. Turning the potentiometer shaft results in a spool posi-
tion or pressure change. Turning clockwise will increase valve
opening PA or pressure. After adjustment refit the sealing
ring and the locking screw.
9 Service
Replacing O rings: The mounting surface O rings may be re-
placed by the customer. Pay attention to cleanliness of the
valve and of the surroundings.
Transportation/storage: Before transportation, seal the base
of the valve using a clean shipping plate or adhesive tape.
Seal the connector using a dust protection cap. Pack the valve
carefully so that it is not damaged during transportation or stor-
age.
Inspection: Following a period of storage or no operation for
more than 5 years, we recommend that the valve is inspected
by an authorized service center, in order to prevent possible
damage.
Repairs: Repairs may only be carried out by us or by our au-
6.8
thorized service centers.
10 Disposal
It is essential to comply with the relevant national waste dis-
posal regulations and environmental protection provisions
when disposing of valves, spare parts or accessories, packag-
ing that is no longer needed, hydraulic fluid or auxiliary materi-
als and substances used for cleaning!
