Electrical Interfacing
Supply Voltage
The supply voltage for the valve has to cover the
range of 22...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 30V! Non-ob-
servance 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 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 time lag.Non-observance of this instruc-
tion may create irreparable damage of valve
resp. 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 approx.5 Nm after attaching the female
connector on the socket outlet.
Incomplete tightening of backshell nut resp.
cap nut may result in automatic release of the
connection as well as degradation of the
water tightness.
Follow the “instructions for use“ for installation
of female connectors made by other kind of
brands!
The cable connection to the female connector
has to take place by qualified 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
carefully tied 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 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.
Incorrect signal amplitude levels may disturb
the functionality and can damage the valve.
The option 4...20 mA uses the “3.6 mA“ con-
dition as breakdown-information.This means
the presence of an evaluable failure informa-
tion 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 NAMUR-
specification NE43.
NAMUR is an association of users of process
control technology.
Diagnostics output
A diagnostics 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.
5. Operating Instructions
Preferred Hydraulic Initial State
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 (approx.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.

A signal voltage enables the actuator drive of the
valve. Continuous operation of the valve requires a
permanent voltage 5...30V (i.e.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 rules for accident prevention!

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 repaired (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 theVCD actuator due to overload
will be signaled via the diagnostics output.

Extended functions:
The user software is shared 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 tomalfunction! In case of parameter
changes shut the drive down!
To prevent an unauthorized access for the expert
mode, a pass word is requested. The name is
“parker” and cannot be changed. Thus additionally
to the button “Default” for loading of the default
parameters, the button “Send parameter” appears
in the “Expert”-operating mode. This button trans-
mits 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 pre-
view 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 RS232 interface port via the menu item “Port”.
Via the menu item “Load file” previously stored
parameter sets may be loaded.

Failure message Description/corrective action
The Com Port is not available! Terminate the other program, or quit the message and select ano-
ther RS-232 port via the menu “Options > Port”. Afterwards recon-
nect the parametrizing cable.
Unable to open COM port Com port is not available. Quit the message and select another
RS-232 port via the menu “Options > Port”. Afterwards reconnect
the parametrizing cable.
There is no module/valve
connected or the communica-
tion is disturbed! Please check
also the interface!
No data exchange possible. Either the electronic has been remo-
ved, 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 parame-
ters?
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 connec-
ted hardware. Attention! Unsa-
ved 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 parame-
ters 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, afte-
rwards 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”.
file name.pxd already exists.
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.
