Characteristics

The valve electronics described in this documenta-

tion relates to the control of high response direc-

tional control valves with solenoids, series D**F.

The electronics is an integrad part of the valve,

unifying various functions necessary for the opti-

mum usage of the valve and leading to an inte-

grated solution. The result is an outstanding dy-

namic response, permitting the valve to be used in

closed loop controls. The integrated electronics

carry out the following functions:

• Provides a specially designed output power

stage for high dynamic control of the solenoids

• Constant current control of the solenoids

• Overriding main stage stroke control

• Specially developed position transducer for high

resolution high dynamic control

• Differential input stage

All the information have been carefully selected

and assembled and represents the actual knowl-

edge.

Power Supply

The utilized power supply has to comply with the

EMC-standards (CE-sign, certiﬁcate of conformity).

Parker is offering the following power supplies:

Relais and solenoids operating from the same

supply circuit as the valve electronics has to be

ﬁtted by surge protection elements.

Wiring Cable

The wiring cable between the control cabinet and

the valve has to be shielded. The central wiring has

to be installed from a 7wire cable that utilizes a

common shielding and a cross section of min.

AWG17. The capacity should not exceed a value

of approx. 130pF/m (wire/wire). The maximum

cable length is 50m. No power current lines may

be placed in parallel to the valve´s wiring cables.

The cable shield has to be connected to earth

ground at both ends (see also chapter “Ground-

ing“). Please be aware of ground-loops.

INSTALLATION GUIDE

TO PROVISION OF ELECTROMAGNETIC COMPATIBILITY

Connectors

The central connection of the valve electronics

needs a connector 6pin+E according DIN 43563

featuring metal case and integrated cable shield

coupling. Parker can provide suitable connectors:

5004072 (Connector 6pin+E)

The connectors have to be installed according the

connection diagram, the cable shield has to be tied

on the whole periphery to the provided coupling

clamp.

Grounding

The mounting plate of the valve has to be con-

nected to the grounded metal machine frame. The

Earth wire to pin G of the central wire cable as well

as the cable shields of the valve connection cables

should be tied to earth ground at the control cabi-

net. A low-ohmic potential compensation wire has

to be provided between the control cabinet and the

machine frame (cable wire >AWG7

cross section)

to prevent ground loops.

The connecting cable has to comply to the follow-

ing 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 factory.

The connection cable is coupled to the female

connector by solder joints.

3. Installation

Electrical Connection

The electrical connection of the valve takes place

by one common cable, which is coupled to the in-

tegrated electronic driver by a central connector

assembly.

The connection requires a 6 + PE female connec-

tor EN 175201-804.

The female connector has to be ordered

separately under article nr. 5004072.

A female connector with metal housing is

required! Plastic made models may create

function problems due to insufﬁcient EMC-

characteristics.

Signal-Input

The command signal input of the valve has been

wired from the connector terminals D and E to the

differential input of the onboard electronic. The

valve stroke is acting proportional to the value of

the signal. According to the valve model there are

different command signal options available, which

are separately described below. More details are

obvious from the technical data. The input signal

must be ﬁltered as well as free of surges and

modulations. Due to the resolution sensitivity a high

signal quality is recommended, to avoid function

disturbances.

Improper high signal amplitudes may lead to

function disturbances or damaging depend-

ing of the exceeding value.

The explanation of functionality assumes

junction E as point of reference potential.

Wiring example of voltage input option +10...0...-10 V

Wiring example of current input option 4...12...20 mA

Wiring example of current input option +20...0...-20 mA

Command signal option 4...20 mA uses the “0 mA“

- condition as failure information. This means that

an evaluable failure information is provided for an

interrupted command signal circuit. In the present

case the solenoid drive thereby will be switched off.

The drive will be activated if the input signal ex-

ceeds a value of 3,8 mA and will be disabled below

3,6 mA. This deﬁnition follows the NAMUR standard

NE43.

Min/Max-Setting

The min/max-setting option achieves a conditioning

of the valve operating range to a certain application.

The min-setting is used for valves with overlapped

main spools, it compensates for the mechanical

overlap by an offset-feature.

The max-setting limits the stroke of the valve spool,

equally the full input signal range will be preserved

and can be used with full resolution.

Both settings are provided separately for both valve

operating directions.

Diagnostic Output

To make available measurements for the momen-

tary position of the valve spool the valve electron-

ics unit provides a diagnostic output. This is avail-

able at the main connector between pin F and

supply zero (pin B) as well as on the printed circuit

board of the valve electronics unit which provides

two diagnostic sockets. The sockets take 2mm

plugs and can e.g. be used in the setting up of the

zero point.

The output is a 0...±10V signal where the value of

10V normally represents the maximum permitted

stroke of the valve spool.

The diagnostic output is short circuit proofed and

is fully operative up to a load of at least 2kOhms

or 5mA.

Position Control

The purpose of the position controller is to compare

the actual value of the spool as given by the valve

electronics sensor with the set value and provide

signals to the actuating solenoids to ensure that

the set position is achieved and maintained. The

sketch below shows the operating principle of the

control circuit.

Power Stage

In the output stage the output signal of the position

controller is converted into an activating signal for

the operating solenoids.

Keeping the power relationships at the solenoid

constant as well as the need for rapid excitation of

the solenoids is achieved with controlled current

from a constant current control stage.The solenoid

current is measured in the valve electronic unit and

compared with the set-value for current in the

constant current controller. As long as there is a

difference between set and actual current values

the output stage will change the solenoid current

in order to equalise them.The solenoid also has a

superimposed dither signal which has been care-

fully matched with the mechanics of the valve to

compensate for mechanical friction so that the

hysteresis will not inﬂuence the dynamics of the

valve.

Enable Signal Input

To switch-off the output stage the valve electronics

unit is ﬁtted with an enable signal input which can

at any time be used to interrupt the solenoid current

irrespective of transducer signal or set value. In this

case the main spool takes up - without any delay

- the spring centered position in the valve.

A further function of the enable signal input is to

limit the output of the position control. Normally on

switching off the activated solenoid the output of

the controller would be driven into saturation by the

Integral part of the PID system. Because of this, if

the solenoid is immediately switched on again the

valve spool is for a short period of time operated

indeﬁnetily. To avoid this, the integral part of the

controller is switched out and a limit is placed on

the controller output for as long as the enable input

is switched off. When the enable signal is switched

on again the valve spool will immediately move

from it's central position and take up the required

set position.

The enable signal input is, as far as circuitry is

concerned, completely isolated from the rest of the

electronics to keep interference from peripheral

equipment away from valve electronic unit. It re-

quires a signal in the region of 5 to 30VDC with a

current supply of about 10mA. The enable signal

is fed into the unit via the central connector between

pins B and C.

5. Measuring Points

Note

Position Of The Measuring Points

Measurements as described at the points shown

on the diagram below may only be made by

experienced personnel (electronic) to ensure

that damage is not done to the valve electronic

unit.

The enable signal should preferably be switched

off together with the hydraulic pressure source in

order that the solenoid spools have no circulating

current when the hydraulic system is switched off.

This reduces energy loss and unnecessary heat

generation in the solenoid spools.

Note

The enable signal does not provide security against

unwanted operation of a valve in the sense of the

accident prevention regulations. To block all pos-

sibility of a valve functioning under any circum-

stances, further steps are necessary, e.g the ﬁtting

of safety lock valves.

Voltage Monitor

The supply voltage may therefore lie between 18

and 30V, with a ripple of no more than 5%. These

voltages are valid on load i.e. with valve electronics

and enable signal connected.

The value of the supply voltage is supervised by

an integrated voltage monitoring.

Control Failure Monitor

If a failure >2% occurs within the position control

loop of the valve a control failure signal is given.

This is the case, if the valve spool does not reach

the predetermined position. The most important

reasons for this behaviour could be:

• No or too low pilot presssure

• Blocking or defective valve mechanics by dirt

• No enable signal

• Input signal failure (only for option 4...20mA)

The operating condition of the monitoring is indi-

cated by a dual color LED within the valve electron-

ics cover.

An explanation of the light indicator is printed on

the placard on the cover.

6. Commissioning

Ambient Conditions

The valve electronics unit has been designed to

work reliably together with the hydraulic valve as a

unit under normal industry conditions. It is pro-

tected against environmental inﬂuences by its cast

iron housing which also prevents the entry of for-

eign particles and is sealed against the entry of

water.The electronics are partly encapsulated and

have a protective coating of varnish.

Even so, mechanical loading of the electronics box

as well as its use outside of the following installation

conditions is not allowed as permanent damage or

a reduction in working life cannot be ruled out. It is

advisable to install the unit directly by the machine,

protected from extreme environmental inﬂuences.

Input Circuitry

The differential input of the valve electronic unit

ensures a freedom from input problems with the

user’s set value signals.

Command Signal Control System

There are three basic variations on set value con-

trol:

• Take the set value signal from a programmable

logic control unit (PLC).

• Set value control through interface electronics.

• Set value signals from preswitched controller.

Conditions

ing.

Adjustment

1. Loosen locking cover nut of the adjusting spindle.

2. Adjust the zero point until the actuator is in the

neutral position or takes up the desired creep

position.

3. Replace cover nut.

The following command signal value results in the

electrical zero point of the valve:

Enable Signal

The valve electronic unit uses an “enable” signal

function in the range of 5...30V at pin C of the main

connector (see chapter “Enable Signal Input“).

There are two different ways of controlling the en-

able signal input:

• Using the 24V supply voltage through an enable

switch provided by the user.

• Feeding the enable signal from a control system

of the user with the reference (zero) point of the

user's control connected to pin B of the central

connector and the enable signal is connected to

pin C.

The enable signal must only be switched on to

the valve electronics unit when the valve is to be

used; all other times should be off.

Example: Start-up of a hydraulic control system

As against the supply voltage, which will be switched

on at the same time as the hydraulic system, the

enable signal should preferably not be switched on

until the hydraulic system has reached full pressure.

This will prevent any system disturbance.

Zero Point Equalising

The main valve spool takes up the spring-centred

position if the power fails or the enable signal has

not been given. Valves with overlap spools have a

factory adjusted zero point. Valves with zero lap

spools usually have mechanical centering. In this

case there is a possibility of the operating condi-

tions allowing the activated device e.g a cylinder,

to creep in an uncontrolled direction; the valve

electronics unit takes account of this possibility and

allows the creeping movement in a predeﬁned di-

rection only.

Valves with overlapping type spools are factory-

preset to null. In the case of valves with zero lap

spools it is necessary for the user to adjust the

electrical zero point in accordance with its require-

ments. The adjusting can be done via a selﬂocking

spindle trimmer in the valve electronic unit. The

position of the trimmer is shown on the placard on

the cover.
