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.
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.

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: 2.0 A time lag
Valve phasing: A positive signal (D–E) for 6+PE connector
causes valve opening PA.
Connector wiring: See wiring schematic tag attached to elec-
tronics housing or refer to the catalog.
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.

6 Hydraulic System Start Up
Pay attention to the pressure setting, the venting instructions
and the alarm messages!
7 Null Adjustment
After removing the locking screw (M25), along with the seal on
the cover of the electronics housing, a multi-turn potentiometer
is accessible (item 1). Turning the potentiometer shaft
changes the control plunger position. Turning in clockwise di-
rection increases the valve opening PA. The actual value of
the control plunger position also changes. On completion of
the setting work, the locking screw inc. seal must be rein-
stalled.
The mini USB connection (item 2) and the potentiometer
(item 3) are only intended for internal use at Moog and may not
be used.
Attention: Depending on the type of valve, it is possible that
there is no potentiometer at all or only one.
8 Service
Replacing O rings: The mounting surface O rings may be re-
placed by the customer. Pay attention to cleanliness of the
valve and of the surroundings.
Transportation/storage: Before transportation, seal the base
of the valve using a clean shipping plate or adhesive tape.
Seal the connector using a dust protection cap. Pack the valve
carefully so that it is not damaged during transportation or stor-
age.
Inspection: Following a period of storage or no operation for
more than 5 years, we recommend that the valve is inspected
by an authorized service center, in order to prevent possible
damage.
Repairs: Repairs may only be carried out by Moog or by our
authorized service centers.
9 Disposal
It is essential to comply with the relevant national waste dis-
posal regulations and environmental protection provisions
when disposing of valves, spare parts or accessories, packag-
ing that is no longer needed, hydraulic fluid or auxiliary materi-
als and substances used for cleaning!
