Mounting and Installation Notes D085-172 (B97072-085-001; Version G, 02/15)
3 Installation
Compare model number and type with that specified on hy-
draulic schematic. The servoactuator can be mounted in any
position, fixed or movable.
Port threads:
See installation drawing.
Mounting:
Socket head screws (grade 10.9) according to
EN ISO 4762, torque diagonally alternating.
4 Operating Pressure
Maximum operating pressure p
P
:
See nameplate.
5 Electrical Connection
Electrical safety:
The insulation materials employed are de-
signed 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 servoactuator:
0.5 A medium time lag
Servoactuator phasing:
A positive signal (D–E) causes the
piston rod to extend.
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).
6 Hydraulic System Start Up
Pay attention to the pressure setting, the venting instructions
and the alarm messages!
7 Null Adjustment
Remove the locking screw with sealing ring from the cover of
the electronics housing to access the null adjustment potenti-
ometer. Turning the potentiometer shaft results in a piston rod
position change. Turning clockwise will result in rod retraction.
The output signal for actual rod position will also change. After
adjustment refit the sealing ring and the locking screw.
8 Service
Transportation/storage:
Before transporting a servoactuator
the servoactuator ports have to be sealed with adhesive tape.
Package the servoactuator carefully to prevent damage during
transportation
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 us or by our au-
thorized service centers.
9 Disposal
It is essential to comply with the relevant national waste dis-
posal regulations and environmental protection provisions
when disposing of servoactuators, spare parts or accessories,
packaging that is no longer needed, hydraulic fluid or auxiliary
materials and substances used for cleaning!
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).
