control system valve
Electrical Interfacing
Supply Voltage
The supply voltage for the valve has to cover the
range of 22...30 V. Valve is de-energized below
19 V. The residual ripple may not exceed 5 % eff.
The applied power supply must comply to
the relevant regulations (DIN EN 61558) and
must carry a CE-mark. The operating voltage
for the valve must be free of inductive surges.
Do not exceed the max. value of 30 V! Higher
voltage can lead to failure of the valve.
The increased inrush current of the valve
should be considered when selecting the
power supply. A stabilized power supply
with overcurrent limiting feature should not
be used. Due to the inrush current of the
valve the current limit circuit may respond
prematurely and create problems during
energizing of the supply voltage.
The operation of the valve is blocked if the
supply voltage polarity is interchanged.
Each valve requires a separate pre-fuse of 4
Amp semi time-lag. Failure to observe this
instruction may create irreparable damage
of valve respectively incorporated system
parts.
The backshell nut of the cable gland has to be
tighten with a suitable tool. The target value for
the tightening torque is 4 Nm. Tighten the cap nut
with a torque of 5 Nm after attaching the female
connector on the socket.
Incomplete tightening of backshell nut re-
spectively cap nut may result in undesired
release of the connection as well as degrada-
tion of the water tightness.
When using female connectors of other
manufacturers, the relevant regulations must
be observed.
The cable may only be connected to the
female connector by authorized and quali-
ed personnel. A short between individual
conductors resp. to the connector housing
, bad soldering as well as improper shield
connection may result in malfunction and
breakdown of the valve.
The mounting surface of the valve has to be
connected to the earth grounded machine
frame. The earth ground wire from the valve
connecting cable as well as the cable shield
have to be tied to the protective earth terminal
within the control unit. It is necessary to use
a low ohmic potential connection between
control unit and machine frame to prevent
earth loops (cross section AWG 6).

Command Signal Input
The spool stroke behaves proportional to the com-
mand signal amplitude.
The command input signal needs to be l-
tered as well as free of inductive surges and
modulations. Due to the sensitivity of the
valve a high signal quality is recommended,
this will prevent malfunction.
Enable Input
A signal voltage enables the actuator drive of the
valve. Continuous operation of the valve requires
a permanent voltage 5...30 V (i.e. the supply volt-
age). In case of disabling the signal the valve will
reach its power down position spring-actuated
independently from the command signal value.
The enable function represents no safety ar-
rangement against unwanted valve operation
in terms of rules for accident prevention!
The option 4...20 mA uses the “3.6 mA“
condition as breakdown-information. If the
input signal line is interrupted, an evaluable
failure information is available. In this case the
actuator drive will be switched off. The drive
will switch on when the input signal reaches
a value of 3.8 mA, it switches off when the
command falls below 3.6 mA. This determina-
tion follows the NAMUR-specication NE43.
Diagnostics Output
A diagnostics signal is available. Its voltage rep-
resents the operating condition of the valve.
The output may drive a load of max. 5 mA.
Exceeding of this limit leads to malfunction.

5. Operating Instructions
Attention! Supply pressure must be ensured
before valve is energized!
To reach the closed position in case of valve
electronic failure, pilot pressure is required.
Switch on/off Series TEP
When switching on the complete valve, the
D3DW shut-off valve has to be switched at
least 50 ms before enable of the DFplus pilot
valve. When switching off, this order must be
reversed. If this is not observed, vibrations
can occur in the main stage.
Solenoid Current Monitoring
If the actuator current time interval exceeds 10
seconds, the actuator is switched off to prevent
overheating. For normal operating conditions this
state will not reached, but it may occur with a
contaminated sluggish valve.
In this case the reason for the contamination
should be repaired (hydraulic uid exchange,
ltration review, valve ushing).
The overcurrent shutoff condition may be resetted
by temporary disconnection of the enable signal.
Theshutoff oftheVCDactuator duetooverload
will be indicated via the diagnostics output.

Use of Work Equipment Directive.
If the function has been changed signicantly,
a new conformity procedure must be carried
out in accordance with the Machinery Direc-
tive 2006/42/EC.
Electronic Control System
The D3DW valve must be operated by the user
with a suitable control system.
The valve is connected using separate wires for
solenoids/position control.
Solenoid Connection
Each solenoid connection requires one plug 2 +
PE as specied in EN 175301-803.
Connection of Plug
The plug for the solenoid must be ordered
separately.
The wiring must meet the following specications:
Type Flexible control cable, 3-core
Size Min. 1.5 mm²
External diameter PG9: 4.5...7 mm
PG11: 6...9 mm
Length Max. 50 m
For lengths >50 m please contact Parker.
The sealing surface of the valve must be
properly connected to the earthed frame of
the machine. Connect the earth wire and cable
shield to the protective earth in the electrical
cabinet.
Use the screw connectors to attach the wires to
the plug. Use a suitable tool to tighten the screw
at the cable entry point.

Failure to tighten the screw connectors may
cause the connectors to loosen and may
impair the seal.
If you are using plugs from other manufactur-
ers, follow the relevant instructions.
Short circuits between the wires, poor
workmanship or incorrect attachment of
the shielding may cause disruption and the
failure of the valve and the electronic control
system.
Sensor Connection
See "Technical data" page 18
Choice of Solenoid
The choice of a suitable solenoid is an important
factor in the operational reliability of the valve. The
D3DW is available with various solenoid voltages.
If the solenoid can be adjusted by setting param-
eters in the electronic control system, the suitable
solenoid options must be selected.
Note about using valves with actuating so-
lenoids:
The current drops as the solenoid heats up.
The lower current has no effect on valve
operation, provided the specied voltage is
maintained at the valve.
A suitable tool must if necessary be used for
manual emergency actuation of the solenoid.
Remaining Risk
Allergic Reactions
Hydraulic oil can cause allergic reactions on sus-
ceptible skin. This can be prevented by taking the
precautions that are usual when handling mineral
oil products and by using personal protective
equipment.
Leaking Plugs
Leaking plugs can cause a malfunction. That
is why the plugs must be checked for leaks
at the regular maintenance interval. Leaking
plugs may constitute a safety hazard, so the
valve must be returned to the manufacturer
for repair.
Lightning
If electronic components are exposed to
electromagnetic elds as a result of lightning,
they must be checked to ensure they are still
working perfectly. If there is a malfunction, the
product must be returned to the manufacturer.
Temperature
The surface of our product may heat up in use.
The service temperatures may exceed the
temperature threshold for burn injury, 70 °C.
Above this threshold, even brief contact with
the surface may result in a burn.
The only way to consistently prevent burn
injuries is to use personal protective equip-
ment and to remain safety-conscious at all
times.
If integrated electronics are exposed to a
temperature above 80 °C, they may malfunc-
tion.
Power Failure
In a power failure the valve piston returns to
the spring centred starting position.
You must check whether this creates potential
hazards when the system/machine is used.
Hydraulic
The D3DW is tested and approved with an even
ow. If the ow becomes asymmetrical, the safety
function of the valve may be compromised. You
should therefore carry out tests before commission-
ing to verify that the valve is in good working order.
If the valve piston has been under pressure and
stationary in the end position for an extended pe-
riod, oil particles may cause the piston to seize. For
this reason the valve should be actuated regularly.
Electrical Connection for Position Control
The position control can be connected as normally
closed or normally open. In principle, we recom-
mend a normally closed connection, as this is the
only way to ensure that position control works
properly

Correct Use
Our products are manufactured using state of the
art technology and recognised safety procedures.
The D3DW is designed for mould closing devices
in injection moulding machines according to the
manufacturer's installation instructions (see page
19).
According to section 1(2b) of accident prevention
guidelines "Injection moulding machines" (VGB 7
ac) and section 5 of EN 201:1997 "Injection mould-
ing machines. Safety requirements", the valves
must be independently monitored by the control
system of the injection moulding machine, such
that if position control fails, a new machine cycle
is prevented from starting.
Function
The D3DW is deviced that inuence the direction
of a ow. To do this, connections between the
various ports are made or broken. Activating the
solenoid or the hydraulic pilot causes the piston
in the valve to move to the end position.
If the electrical signal is removed, the installed spring
pushes the piston back to its starting position.
The purpose of the installed position control is to
detect when the piston is in the starting position.
The shut-off function causes a control error
when the proportional valve is active, which
cannot be corrected due to the hydraulic
separation.
Electrical Connections
Before commissioning,
• all electrical connections must be made profes-
sionally, using suitable ducting,
• parts of the machine and individually installed
components must be adequately earthed,
• all limit switches and control elements must
be properly integrated with the control system.
Hydraulic Requirements for Pilot Operated
Directional Control Valves
To guarantee that the main piston operates reliably
at all times, the minimum pilot pressure must be
provided. To achieve this, a suitable combination
of ow and return arrangements must be selected
for the pilot oil.

Technical Data
Notes on Installation
• Connections to the limit switch must be laid
separately from mains connections, for example
power supplies to motors or magnets, because
inductive voltage peaks would otherwise pass
via the supply network to the limit switch, which
could be damaged even though a protection
circuit is installed.
• A suitable DC power supply is required for the
switch. The ripple of the power supply must
not exceed 10 %.
• Voltage spikes occurring when inductive loads
are removed should be eliminated using a
suitable protection circuit, for example yback
diodes.
• A bui|t-in overload protection circuit suspends
the switching function of the limit switch if an
overload occurs. When the overload ends, the
limit switch automatically resumes operation.
• The limit switch must not be installed close to
AC consumers, e.g. AC solenoids, which may
cause disruption. A minimum distance of 0.1
m must be observed in all cases.
• The product may only be operated in the condi-
tions set out in the technical data.
• Connections must follow the connection list.
