Electrical Connection
The valve is connected electrically by one common cable and a central connector.
The connection codes 0 and 7 require a 6 + PE female connector EN 175201-804.
The female connector can be ordered sepa-
rately under article nr. 5004072.
In case third party connectors are used, ac­cordance to the relevant EMC directives must be ensured.
The connecting cable has to comply to the follow­ing specification:
Cable type control cable, flexible, 7 conductors, overall braid shield Cross section min. AWG16 Outer dimension 8...12 mm Cable length max. 50 m
For cable lengths > 50 m consult Parker.
The connection cable is coupled to the female connector by solder joints. Skinning lengths for the connecting cable:
The connection Code 5 requires a 11 + PE female connector EN 175201-804.
The female connector has to be ordered
separately under article nr. 5004711.
In case third party connectors are used, ac­cordance to the relevant EMC directives must be ensured.

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 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).

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...30 V (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 opera­tion in terms of accident prevention regula­tions.
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 repre­sents 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
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, cor­responding 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 con­taminated 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 param­eter 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 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 respectively 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 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 “Op­tions/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 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 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 param­eters, 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.

Failure message Description/corrective action
The Com Port is not available! Terminate the other program, or quit the message and select
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 con­nected or the communication is disturbed! Please check also the interface!
No data exchange possible. Either the electronic has been re­moved, 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 param­eters?
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 con­nected 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 param­eters 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, after­wards 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.
