5 Transport and Storage
IMPORTANT
Check the packaging for possible shipping damage.
If damage to the packaging is found, check the content for completeness and
possible damage. In case of damage inform the forwarding agent.
The units are packed ready for
installation. The type plate is at-
tached to the vibrator. If not specified
differently the vibrator is delivered
with an unbalance setting of 100 %.
When transporting the vibrator make
sure to avoid hard impacts or
vibrations which
could damage the
bearings.
The unit should be stored in a clean,
dry environment.
If the vibrator needs to be in storage
for a longer period of time (2 years
max.), the temperature in
the store
must not fall below -10 °C
or above
+25 °C and the relative
air humidity
must not exceed 60 %.
WARNING
If the vibrator is fitted with two
transport eyes, both of these should
be used for lifting. The lifting angle
must not exceed 45°.
The transport eyes must solely be
used to lift the vibrator.

11
6 Installation
IMPORTANT
The installation of the vibrators must only be carried out by authorised, quali-
fied personnel.
The qualified personnel must use only tools which are suitable for the
application.
IMPORTANT
During installation please comply strictly with the safety regulations in chapter
2 and the accident prevention rules!
Installation of the system must be performed in compliance with the local,
applicable regulations (e.g. VDE-regulations).
6.1 Fastening of the vibrator
Netter electric external vibrators can be operated in any position.
During installation the following instructions must be strictly observed:
WARNING
The mounting surfaces must be abso-
lutely level (±0.1 mm
flatness fault),
so that the feet of the vibrators have
full area contact and to avoid warping
of the housing when tightening the
fastening screws. The surfaces
should also be free of any paint resi-
dues and weld penetrations. Ten-
sions in the housing can cause me-
chanical and/or electrical damage.
For safe fastening we recommend the use of Netter NBS screw connections
consisting of screw, special lock washer and, if necessary, nut.
The vibrators can also be fastened with fastening screws of
quality 8.8
(DIN 931 or 933). These must be locked with qualified locking devices and re-
tightened at regular intervals (normally every month).
WARNING
The tightening torques can be taken
from the following table. Higher
tightening torques may cause frac-
ture of screws or tearing of threads.
Inadequate screw connections may
cause loosening of vibrators by
vibration. This can cause damage to
persons and material!

DANGER
In critical installation situations the unit
must be secured additionally by a
steel rope, e.g. NSE.
Adjust the safety rope to the shortest
possible length by using the wire rope
clips.
The safety rope must be under ten-
sion at all times!
6.2 Electrical connection
IMPORTANT
The electrical installation of the vibrators must be performed only by authorised,
qualified personnel.
The qualified personnel must use only insulated tools, which are suitable for the
application.
IMPORTANT
The mains voltage must comply with the nominal voltage indicated on the type
plate.

DANGER
The electric lines have to be laid with care. It has to be avoided that the cables
can be chafed through by vibrating parts.
The perfect condition of the electric lines incl. plugs has to be checked at regular
intervals (as a rule every six months). Defects which are discovered hav
e to be
eliminated immediately.
Protect the cable against high temperatures, lubricants
and sharp edges.

13
7 Start-up
IMPORTANT
During start-up of the vibrators the rules and regulations of the local associa-
tions for electrical engineering (e.g. VDE) and the applicable accident preven-
tion rules must be observed.
The vibrators must always be switched on and off at a main switch.
WARNING
The vibrator must not
be operated
without the cover for the unbalances in
place! The rotating unbalances cause a
risk of injury!
WARNING
The vibrators have to be adapted to your application by adjusting the unbalances.
You can directly influence vibration amplitude, centrifugal force and current
consumption, see chapter 8 „Adjustment of unbalances”.
Exception: NED 605 has a fixed unbalance.
Retightening:
Screw connections must be checked and, if necessary, retightened after 1 hour
of operation (after initial start-
up) and then at regular intervals (as a rule, once per
month).
8 Adjustment of unbalances
IMPORTANT
All vibrators of the series NED (except the NED 605) provide the possibility to
adjust the unbalances.
Unless otherwise specified by you, the units will be shipped with the default
setting (100 %).
By adjusting the unbalances you can directly influence the vibration amplitude,
centrifugal force and current consumption.
WARNING
On all units with adjustable unbalances these must only be adjusted symmetrical-
ly mirrored!
The tables below show the type of unbalance and the number of unbalances per vibrator at
the default setting of 100 %.
How to proceed:
•Switch off vibrator, secure against being switched on unintentionally and check that unit is
voltage-free.
•Remove both unbalance covers.
•Loosen locking nuts and/or safety screws.
•Adjust the unbalances as required.
•Tighten locking nuts and/or safety screws.
•Fasten unbalance covers.

Default number of unbalance discs per vibrator
There are 2 possibilities to adjust the unbalances:
1. The unbalance adjustment (fine adjustment) is carried out by removing one lamella disc on
each side. All centrifugal values in % can be adjusted as specified in the table.
The removed lamella discs must be replaced by compensation washers (available from
NetterVibration) of identical thickness and identical inner diameter.
2. The unbalance adjustment (coarse adjustment) is performed by turning one lamella disc on
each side by 180° on the shaft.
Twice the number of lamella discs turned by 180° becomes ineffective.

15
Unbalance lamella discs of the type XLs
Adjustment of the unbalances is carried out according to a scale disc or the supplementary
sheet in the terminal box of the unit. By rotating the outer, adjustable unbalance disc(s) to
another position, the percentage of the centrifugal force changes as shown in the illustration
below. The grid position is defined by position pins.
Settings:
Example:
The NED 50100 / 12 V or 24 V
has a total of 6
unbalance discs (3 discs per side: 2 fixed, 1 ad-
just
able). If a centrifugal force of 88% is desired,
the adjustable unbalance discs are rotated anti-
clockwise on both sides into the fourth grid posi-
tion.
