WARNING

Carrying-out work on the valves/ machine during
operation

Carrying-out any work during operation, such as e.g.,
hydraulic connection of components, can cause un­controlled sequences of motions, malfunction, and
others, and thus may result in fatalities, serious per­sonal injuries and serious damage to property.

 During operation, do not carry out any work on the

valves/

machine.

 Before working on the valves/

machine, stop the

machine and switch off the supply voltage.

 Secure the machine against restarting. Examples

of suitable securing measures:

• Lock the main command device and remove
the key.

• Attach a warning sign to the master switch.

WARNING

Hydraulic fluid squirting out

Hydraulic fluid squirting out under high pressure or
parts falling off can cause serious personal injuries,
burns and fires.

 Before working on the valves/machine, depres-

surize all hydraulic lines and accumulators.

 When mounting the valves, observe the specifica-

tion of the installation screws and the mounting
pattern and ensure the presence, elasticity, integ­rity and correct seating of the O-rings.

 Observe the maximum operating pressure.
 Please pay attention for signs, such as a slight oil

leak or "sweating", which may indicate an assem­bly error and/or component failure.

WARNING

Wrong handling

Wrong handling of the valve, tools or accessories
may result in fatalities, serious personal injuries and
serious damage to property.

 Only properly qualified and authorized users may

work with and on the valves.

 When working with and on the valves/machine,

observe the machine manufacturer’s notes and in­structions.

CAUTION

Misuse of the connectors, mating connectors
(plugs) and connection cables

Misuse, such as e.g., use as foot hold or transport fix­ture, can cause damage and thus may result in per­sonal injuries as well as further damage to property.

 Use the connectors, mating connectors and con-

nection cables exclusively for the connection of
the valve.

CAUTION

Falling objects

Falling objects, such as e.g., valves, tools or acces­sories, may result in personal injuries and damage to
property.

 Wear suitable safety equipment, such as e.g.,

safety shoes or helmet.

CAUTION

Hot surfaces of valves and hydraulic lines

Valves and hydraulic lines can become very hot dur­ing operation. Contact may result in burns.

 Wear suitable safety equipment, such as e.g.,

work gloves.

CAUTION

Noise emission

Depending on the application, significant levels of
noise can be generated when the valves are oper­ated. This may result in hearing damage.

 Wear suitable safety equipment, such as e.g., ear

protection.

CAUTION

Skin contact with hydraulic fluid

Skin contact with hydraulic fluid may result in per­sonal injuries.

 Observe the safety regulations applicable to the

3 Installation

Compare model number and type with that specified on hy­draulic schematic. The valve can be mounted in any position,
fixed or movable. The venting screw has to point upwards.
Mounting surface: Check for flatness
(< 0.01 mm (0.00004 in) over 100 mm (3.94 in)) and finish
(R

a

< 0.8 µm). Care must be taken to ensure that contamina­tion 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.

4 Operating Pressure

Maximum operating pressure pP: See nameplate.

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 extra­low 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 elec­tronics housing, or refer to the catalog or the installation draw­ing.
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 protec­tive conductor.
Observe technical note TN 353.

6 Hydraulic System Start Up

Pay attention to the pressure setting, the venting instructions
and the alarm messages!

7Venting

8 Null Adjustment (Pressure)

Remove the locking screw with sealing ring from the cover of
the electronics housing to access the null adjustment potenti­ometer. Turning the potentiometer shaft results in a spool posi­tion 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 stor­age.
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 au­thorized service centers.

10 Disposal

It is essential to comply with the relevant national waste dis­posal regulations and environmental protection provisions
when disposing of valves, spare parts or accessories, packag­ing that is no longer needed, hydraulic fluid or auxiliary materi­als and substances used for cleaning!

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. Conden­sation due to temperature fluctuations can result in elec­tronic 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).
