ing specication:
Cable type control cable, exible,
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.
The shielding has to be assembled according the
outline below.
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, ac-
cordance to the relevant EMC directives must
be ensured.
The connecting cable has to comply to the follow-
ing specication:
Cable type control cable, exible,
8 conductors, overall braid
shield
Cross section min. AWG16
Outer dimension 12...15 mm
Cable length max. 50 m
For cable lengths > 50 m consult factory.
The connection cable is coupled to the female
connector by crimp contacts.
The shielding has to be assembled according the
outline below.
Do not disconnect cable socket under volt-
age!
Skinning lengths for the connecting cable:
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 re-
spectively cap nut may result in undesired
release of the connection as well as degrada-
tion 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 qualied
personnel. A short between individual con-
ductors resp. to the connector housing , bad
soldering as well as improper shield connec-
tion 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 be-
tween control unit and machine frame to
prevent earth loops (cross section AWG 6).

D_FP_D 5715-695 UK.indd 16.09.21
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 volt-
age). 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.
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.
