Proportional DC Valves

Series D*FC, D*1FC

Use of the product

The product must only be used if it is perfect in
working order. Problems that may impair safety
must be corrected.

This product is a safety component that may
only be repaired by the manufacturer if it
malfunctions. If the safety components are
repaired by the user, the manufacturer's war­ranty is invalidated because the manufac­turer is demonstrably unable to ensure that
the product is used as specified.

Limits of use

The product may only be operated within the speci­fied limits of use. The relevant details can be found
in „Technical data“.

Ambient conditions must be observed. Un­authorized temperatures, shocks, the effects
of aggressive chemicals, radiation, unauthor­ized electromagnetic emissions may result in
disruptions and failures. Observe the limits
of operation set out in „Technical data”.

Contaminations

Function and service life of the valve are heavily
dependent on the purity and quality of the pressure
fluid and depend upon the operating conditions of
the hydraulic components. Appropriate filters must
be used and regular inspections of the medium
must be carried out to prevent contamination of the
pressure fluid. Permitted level of contamination is
set out in the „Technical data“.

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 Parker for repair.

Lightning

If electronic components are exposed to
electromagnetic fields 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 Parker.

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 equipment and to remain
safety-conscious at all times.

If integrated electronics are exposed to a
temperature above 80 °C, they may malfunc­tion.

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.

Be aware of three important sources of con­tamination:

• Contaminations entering during installation

• Contaminations occurring during operation

• Dirt entering from the surroundings

Remaining risks

Allergic reactions

Hydraulic oil can cause allergic reactions on
susceptible skin. This can be prevented by taking
the precautions that are usual when handling min­eral oil products and by using personal protective
equipment.

D_FC 5715-686 UK 07.02.2019

Hydraulic

D*FC/D*1FC valves are tested and approved with
an even flow. If the flow becomes asymmetrical,
the safety function of the valve may be compro­mised. You should therefore carry out tests before
commissioning 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 pe­riod, oil particles may cause the piston to seize. For
this reason the valve should be actuated regularly.

Operation Manual

Electrical interfacing

Supply voltage:

The supply voltage for the valve has to cover the
range of 18...30 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 Non­observance of this rule may result in perma­nent damaging 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 (rat­ing: s. techn. data). Non-observance of this
instruction may create irreparable damage of
valve resp. incorporated system parts.

Enable input (only for Code 5 / 11+PE and
Code 7 / 6 + PE)

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 voltage).
In case of disabling the signal the valve will reach its
hydraulic default (power down) position in no time
independently from the command signal value. At
the same time the position controller output will be
clamped. In case of restarting the enable signal,
the valve spool takes its position always out of the
power down. Preferable the enable signal should
be switched on together with the hydraulic pressure

supply. This forces the actuator drive into drop out
condition when the hydraulic system is switched off,
and it avoids needless heating of the actuator.

The enable function represents no safety
arrangement against unwanted valve opera­tion in terms of rules for accident prevention!
To block the valve function under all conditions,
more advanced steps are necessary, i.e.
the installation of additional safety check
valves.

Command signal input

The command signal for the valve will be connected
to the pins D and E of the difference signal input
of the electronic driver. The spool stroke behaves
proportional to the command signal amplitude.
Different versions of command signal processing
are available, depending on the valve type. These
are described below:

For the function description is assumed as signal
reference (0V):

Code 0: pin E, Code 7: pin E, Code 5: pin 5

Details are shown from the technical specifi-

cations.

The command input signal needs to be filtered

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.

Proportional DC Valves

Series D*FC, D*1FC

Incorrect signal amplitude levels may disturb
the functionality and can damage the valve.

The option 4...20 mA uses the “0 mA“ condi-

tion as breakdown-information. This means
the presence of an evaluable failure informa­tion if the input signal line is interrupted. 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 determination follows the NAMUR­specification NE43.

NAMUR is an association of users of process

control technology.

ProPxD parametrizing software

The ProPxD software allows quick and easy setting
of the digital valve electronics. Individual parameters
as well as complete settings can be viewed, changed
and saved via the comfortable user interface.
Parameter sets saved in the non-volatile memory
can be loaded to other valves of the same type or
printed out for documentation purposes.

directly at www.parker.com/propxd for free software
download.

Parametrizing connection

Hardware requirements

• PC with operating system from Windows® XP
upwards

• Interface RS232C

• display resolution min. 800 x 600

• connection cable between PC and electronic
module

• storage requirement approx. 40 MB

Cable specification

The cable which is required for the connection of
the valve electronic to a PC may be ordered un­der code 40982923. The cable has to be inserted
between an unused serial port of the PC and the
5pole socket connector of the valve electronic
(parametrizing connector).

Attention! The valve electronic provides no
USB interface, but can only be parametrized
via an RS232 - connection. Therefore the
usage of USB standard cables is permitted
and may result in damaging of valve resp. PC.

Operation Manual

Program installation

Please check before installation if the above hard­ware requirements are met. If your PC has already
stored an older version of the “ProPxD” program,
it has to be deinstalled by using the Windows®
system control feature.

Program installation sequence:

• terminate the execution of other programs

• execute the file “setup.exe”

• follow the instructions on the screen

Answer the question, if an older version should be
overwritten, with “ok”. During the installation you
may change destination drive resp. installation path,
if needed. Please answer “ok” if at the end of the
installation the program reports any system informa­tion. After successful installation the desktop display
shows the ProPxD icon for starting the program.

Software operating

Brief instruction for first startup:

• Connect the valve electronic to the supply voltage.

• Connect the valve electronic to a PC via the
parametrizing cable.

• Start the operating program.

• After displaying the program resp. data base ver­sion a program window opens and the connected
valve will be automatically identified (possibly a
manual identification via the button “Receive all”
is necessary).

• Select the desired version via the menu “Op­tions/Optionen” with the menu item “Language/
Sprache”.

• The valve specific default parameters are already
available within the parameter table.

• Individual parameters may be selected via
mouse or the arrow buttons at the center of the
program screen.

• Parameter changes are possible via mouse or
the arrow buttons on the bottom left within the
program screen, also the parameter values may
be edited via the keyboard.

• Modified parameters will be stored via the “Enter”
key or via the button “Update list”.

• Parameters have to be nonvolatile stored on the
valve via the button "save parameter".

Proportional DC Valves

Series D*FC, D*1FC

• The chosen parameters may be optionally stored
on the PC via the “File”-menu with the menu item
“Save as”, data retrieving is always possible via
the function “Load file”

Extended functions

The user software is shared into 2 parameter ranges:

• basic mode

• expert mode

For normal startup the basic mode is absolutely
sufficient. It permits the setting of all application
specific parameters to match the valve function with
the task setting. In case of special applications the
valve parameters may be adapted via the expert
mode. The operating mode may be selected from
the “Options”- menu and remains after terminating
and re-start of the program.

Changing of expert parameters is only permit­ted for qualified personnel. Incorrect settings
may lead to malfunction! In case of param­eter changes shut the drive down!

The expert mode is protected by a pass word
request. The name is “parker”. The button “Send
parameter” appears in the “Expert”-operating mode.
This button transmits only the setting of one single
parameter to the connected valve. Thus a quick
tuning of single parameters is permitted during
the setup.

A horizontal bar graph readout between the

communication buttons shows the data trans­fer state.

Because the ProPxD program has also offline

(i.e. without connection to the valve) function­ality, a manual pre-selection of the parameters
is possible. After selection of the valve type
via the menu “Options” the parameters may
be set and stored for later transmission. Note
the design series while selection of the valve!

The “File” menu provides the functions “Printer
setup”, “Print preview” and “Print”. The pr int preview
includes the option for parameter set storage as
text file (format.txt) prior to further processing. The
“Options” menu provides also the selection of the
RS232C interface port via the menu item “Port”.
Via the menu item “Load file” previously stored
parameter sets may be loaded.

Operation Manual

Proportional DC Valves

Series D*FC, D*1FC

Operation

If any of the safety features of the product are

not operational, the system/machine must be
shut down immediately.

Do not carry out any activities that might

jeopardize safety.

Note also the information in sections “Warranty and
liability”, “Use of operating instructions)”, “Compli­ance with other rules and instructions”, “Personnel
requirements”, “Remaining risks”.

Modification

We define modification as the replacement of a
defective valve with a new valve of the same series.
In particular, it is not permitted to open the valve.

Make sure that the hydraulic system/machine

is unpressurised before the product is in­stalled/removed.

Service/maintenance

Service work may only be carried out by

qualified personnel. Detailed knowledge of
the machine functions concerning switching
on and off as well as of the required safety
relevant technical tasks is required!

Periodical maintenance is essential for the longevity
of the system and guarantees reliability and avail­ability. The following properties of the system has
to be checked in continuous short time intervals:

• oil level in the tank

• max. working temperature

• condition of the pressure fluid (visual inspection,
color and smell of hydraulic fluid)

• working pressure levels

• gas pre-load pressure on the pressure accu­mulator

• leakage on all system components

• condition of filter elements

• condition of hose lines

• cleanliness of components

After a certain operating duration a change of the
hydraulic fluid is required. The frequency of change
depends from the following circumstances:

• kind resp. grade of the pressure fluid

• filtering

• operating temperature and environmental
conditions

Air bleeding of hydraulic system

During initial startup, after an oil change as well as
after the opening of lines or valves the hydraulic
system must be air bleeded.

Filter

The function and lifetime of the valve are strongly
affected by the cleanliness of the fluid.
Purity level class of 18/16/13 acc. ISO 4406 is
required.

Flushing

It is recommended to flush the pipelines by short
circuiting the pressure and return lines. This prevents
the installation dirt from entering the valve.

Decommissioning

Make sure that the hydraulic system/machine is
unpressurised before the product is removed. Note
also the information in sections “Warranty and
liability”, “Use of operating instructions”, “Compli­ance with other rules and instructions”, “Personnel
requirements”, “Remaining risks”.

Trouble shooting

Basis of troubleshooting is always a systematic
approach. At first the following questions have to
be checked:

• Are there practical experiences with similar
failures?

• Have system adjustments been changed?

Afterwards starting of troubleshooting by means of
a priority list of the most likely reasons.

For suspect of a sluggish spool the valve may
be flushed with clean pressure fluid.

Troubleshooting in a hydraulic system requires
in either case a systematic approach. The
work may exclusively be performed by
qualified personnel, as it requires detailed
knowledge about function and construction
of the system. Reversals or disassemblies
may not be taken imprudently! Prior to the
works it has to be clarified, if the system has
been operated properly until the failure oc­cured.
