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 30V! 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 prema-
turely 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 respec-
tively cap nut may result in undesired release
of the connection as well as degradation 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 qualified person-
nel. 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 termi-
nal 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).

Enable input (only for Code 5 / 11+PE as well
as Code 7 / 6+PE)
A signal voltage enables the actuator drive of the
valve. Continuous operation of the valve requires a
permanent voltage 5...30V (e.g.the supply voltage).
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
arrangement against unwanted valve opera-
tion in terms of accident prevention regula-
tions.
Command signal input
The spool stroke is proportional to the command
signal amplitude.
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.

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
determination follows the NAMUR-specifica-
tion NE43.
NAMUR is an association of users of process
control technology.
Diagnostic output
A diagnostic signal is available. Its voltage repre-
sents the operating condition of the valve.
The output may drive a load of max. 5 mA.
Exceeding of this limit leads to malfunction.

• connection cable between PC and electronic
module
• memory requirement approximately 40 MB
If your PC has no serial interface according
to RS232C standard you require in addition
an USB-RS232C adapter.
Cable Specification
Attention! The valve electronic provides no
USB interface, but can only be parametrized
via an RS232C - connection. Therefore the
usage of USB standard cables is not allowed
and may result in damaging of valve respec-
tively PC.

5. Operating Instructions
Spool Position at Power Down/Center Position
For valves with zero lap spools, distinction
must be made between hydraulic neutral
position and power-down position. Neutral
position is taken at neutral input signal, cor-
responding to zero position of the hydraulic
symbol. When the valve is switched off – no
supply voltage, no enable, current signal (code
S) < 3,8 mA – zero lap valves take the power
down position (approximately 10 % opening)
according to the ordering code.For valves with
overlap spools, neutral position and power
down position are the same (zero position).
Supply pressure must be ensured before valve
is energized.
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 con-
taminated sluggish valve.
In this case the reason for the contamination
should be rectified (hydraulic fluid exchange,
filtration review, valve flushing).
The overcurrent shutoff condition may be resetted
by the actions below:
Code 0: Temporary disconnection of the supply
voltage.
Code 5: Temporary disconnection of the enable
signal.
Code 7: Temporary disconnection of the enable
signal.
The shutoff of the VCD actuator due to over-
load will be indicated via the diagnostics
output.
ProPxD parameterizing software
The ProPxD software permits comfortable param-
eter setting. Via the clearly arranged entry mask
the parameters can be noticed and modified.
Storage of complete parameter sets is possible as
well as printout or record as a text file for further
documentation.
The PC software can be downloaded free of charge
at www.parker.com/euro_hcd – see page “Support”
or directly at www.parker.com/propxd.Please check
periodical for updates.

Program installation
Please check before installation if the above hard-
ware 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 respectively instal-
lation 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:
• Connectthe valveelectronic tothe supplyvoltage.
• Connect the valve electronic to a PC via the
parametrizing cable.
• Start the operating program.
• After displaying the program respectively 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 “Op-
tions/Optionen” with the menu item “Language/
Sprache”.
• The valve specific default parameters are already
available within the parameter table.
• 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”.
• 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 segmented into 2 parameter
ranges:
• basic mode
• expert mode
For normal startup the basic mode is sufficient. It
permits the setting of all application specific pa-
rameters 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 permit-
ted for qualified personnel. Incorrect settings
may lead to malfunction! In case of parameter
changes shut the drive down!
To prevent an unauthorized access for the expert
mode, a password is requested.The name is “parker”
and cannot be changed. Thus additionally to the
button “Default” for loading of the default param-
eters, 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
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 print 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.

another RS232C port via the menu “Options > Port”. Afterwards
reconnect the parametrizing cable.
Unable to open COM port Com port is not available. Quit the message and select another
RS232C port via the menu “Options > Port”. Afterwards reconnect
the parametrizing cable.
There is no module/valve con-
nected or the communication
is disturbed! Please check
also the interface!
No data exchange possible. Either the electronic has been re-
moved, the port is mismatched, or the connection will be disturbed
by strong electrical fields. Check if the Com port is set for “9600, 8,
1. none, none” via the menu “Options > Port”.
Wrong password Retype the password, notice the exact spelling (case sensitivity).
Wrong input An unvalid character or a value outside the permitted range has
been used at parameter entry.
Keep the entered param-
eters?
During parameter loading from the electronics memory the preset
parameters from the left hand screen display may be rejected or
maintained.
The chosen module/valve
isn´t the same as the con-
nected hardware. Attention!
Unsaved parameters will be
lost.
In principle, parameters dedicated to a type which deviates from
the connected valve may be edited. However, for data transmitting
the correct valve has to be connected. If parameters will be loaded
from a valve which deviates from the selected one, the param-
eters from the left hand side screen display of the program will be
overwritten.
The chosen hardware isn´t
the same as the connected
module/valve.
The wrong valve type has been selected from the database, after-
wards the function “send all” has been executed.
Attention! Factory settings
will be changed! Transmit
anyhow?
Default parameters has been read out from the database instead
from the valve via the function “receive all”.

Do you want to replace the
file?
The file name already exists within the indicated directory. Select
another name, another directory or overwrite the existing file with
“OK”.
Error messages
Malfunctions when using the ProPxD software program will be indicated via appropriate failure messages.
Failure messages and corrective actions:
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. ISO4406 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.
