Electrical Interfacing - Parker D41FE Operation Manual

Operation Manual
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 instal-
lation 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 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).

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-
observance of this rule may result in perma-
nent 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.
