NOTICE
Damage due to dirt, moisture and ozone/UV effects
• Storage outside or under the wrong climatic conditions can
cause corrosion and other damage to the valve. Conden-
sation due to temperature fluctuations can result in elec-
tronic malfunctions.
 In the case of intermediate storage, observe the follow-
ing storage conditions:
• Recommended ambient temperature: +15 to +25 °C
(+60 to +78 °F), permissible temperature: –40 to
+80 °C (–40 to +176 °F), temperature fluctuation:
< 10 °C (18 °F)
• Relative humidity: < 65 % not condensing
• Ensure there are minimal vibration and shock where
valves are stored
 Following transport or storage, wait until the valves have
reached ambient temperature before starting up.
• Dirt and moisture can enter the valve through openings
and cause damage. Seals can be damaged due to the
effects of ozone and UV.
 During storage and transport, seal connectors with dust
protection caps and install the shipping plate on the
mounting surface.
 Remove dust protection caps and shipping plate only
shortly before mounting the valves and keep packaging
materials for future storage and transport.
 Seal with protection caps any valve connectors that are
not used in operation (without mating connector).
Compare model number and type with that specified on hy-
draulic schematic. The valve can be mounted in any position,
fixed or movable. The venting screw has to point upwards.
Mounting surface:
(< 0.01 mm (0.00004 in) over 100 mm (3.94 in)) and finish
(R < 0.8 µm). Care must be taken to ensure that contamina-
a
tion does not enter the hydraulic system, all work areas must
be clean of surface or air-borne contamination.
Mounting: Socket head screws (grade 10.9) according to
EN ISO 4762, torque diagonally alternating.

4 Pilot Mode and Maximum Pressures
Pilot mode: Pay attention to the hydraulic connection scheme
and to the mounting pattern of the hydraulic manifold. Pay at-
tention to the hydraulic schematic on the valve nameplate and
to the type designation defining the pilot mode.

5 Electrical Connection

Electrical safety: The protective conductor connection is con-
nected to the electronics housing or valve body. The insulation
materials employed are designed for use in the safety extra-
low voltage range.
To comply with safety regulations requires isolation from the
mains according to EN 61558-1 and EN 61558-2-6 and limiting
all voltages according to EN 60204-1. We recommend using
SELV/PELV power supplies.
Rated signal: See nameplate.
External fuse per valve: 0.5 A time lag
Valve phasing: A positive signal (D/4) causes valve opening
PA.
Connector wiring: See wiring schematic tag attached to elec-
tronics housing, or refer to the catalog or the installation draw-
ing.
Connection: Signal lines shielded, shielding connected at
both ends and additionally connected to reference potential
(0 V) at the control side (to improve EMC). Connect the protec-
tive conductor.
Observe technical note TN 353.
Before applying electric signals the pilot stage has to be pres-
surized (not with D691/2/3/4).
6 Hydraulic System Start Up
Pay attention to the pressure setting, the venting instructions,
the fail-safe functions and the alarm messages!
7 Venting
Hydraulic fluid squirting out
Hydraulic fluid squirting out under high pressure or
parts falling off can cause serious personal injuries,
burns and fires.
 Only vent the valve and the actuator at a low sys-

the electronics housing(s) to access the null adjustment poten-
tiometers. (On valves without integrated pressure electronics
no pressure potentiometer is available.) Turning the potenti-
ometer shaft results in a spool position or pressure change.
Turning clockwise will increase valve opening PA or pres-
sure. The output signal for actual spool position will also
change. The electric actual pressure value will not change. Af-
ter adjustment refit the sealing rings and the locking screws.
