control system valve
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 30 V!
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).

Parker Hannifin Corporation

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 modu-
lations. Due to the sensitivity of the valve a
high signal quality is recommended, this will
prevent malfunction.
Enable input
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 ar-
rangement against unwanted valve operation
in terms of rules for accident prevention!
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.
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.

The cover plug has to be re-installed after
completion of the parametrizing work.
Plug for
parametering interface
5. Operating Instructions
Attention! Supply pressure must be ensured
before valve is energized!
To reach the closed position in case of valve
electronic failure, pilot pressure is required.
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 temporary disconnection of the enable signal.
The shutoff of the VCD actuator due to overload
will be indicated via the diagnostics output.

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.

6. Troubleshooting
Basis of troubleshooting is always a systematic
approach.
For suspect of a sluggish spool the valve may
be flushed with clean pressure fluid.
Troubleshooting in a hydraulic system requires
detailed knowledge about function and con-
struction of the system. Therefore the work
may exclusively be performed by qualified
personnel.
