Function

The Electric External Vibrators of the series NED are direct current motors/ asynchronous motors with inverter, with adjustable weights (unbalances) mounted on their shaft ends.
The NED generate circular vibrations, that means the vibrations act in all directions of a plane.
The centrifugal force can be changed by adjustment of the unbalances.

Transport and storage

Observe the safety instructions in Ch. Safety, from page 5 on.
Please refer to the brochure for weights and dimensions.

Transport-conditions

When transporting the NED, ensure that the NED is not subjected to strong impacts or vibrations that could damage the bearings. Please observe the following notes:

• Use only the transport eyelet/eyelets (1) for lifting the NED. If the vibra-tor is fitted with two transport eyes, both must be used for lifting.
• The pulling direction must not exceed 45°.
• Lifting tools are of the usual kind such as a pulley or a crane. When moving loads, use suitable steel cables or hoisting slings which are suf-ficiently dimensioned for these weights.
• Handle the NED very carefully during transport.

Packaging

The NED are packed ready for installation.
The packaging protects the NED from transport damage. The packaging material has been selected from an environmentally safe and technically disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and reduces the amount of waste.

Storage

• Store the NED in a dry and clean environment.
• The permissible storage temperature is between -15 °C and +60 °C.
• The permissible relative humidity is max. 60 %.
• The storage time is max. 2 years.
• Do not store the NED outdoors. The electrical components are not protected against corrosion.

Installation

Observe the safety instructions in Ch. Safety, from page 5 on.
Please refer to the brochure for weights and dimensions.

Fastening the NED

The NED can be operated in any position.

1. Notice: The feet of the NED must lie completely on the surface so that there is no tension in the housing when tightening the fastening screw/screws, which could cause mechanical damage. The mounting surface has to be flat (±0.1 mm flatness) and clean with no paint residues or burn-ins.

2. The vibrators can be fastened with fastening screws of quality 8.8 (DIN 931 or 933). These must be secured with appropriate locking de-vices and checked and retightened at regular intervals (usually month-ly). For safe fastening NetterVibration recommends the use of fastening kits NBS consisting of a screw, a special lock washer and (for NBS D) a nut.
   Fasten the NED with the fastening screws on the mounting surface. Use a torque wrench and tighten the screws crosswise. Observe the recommended values for screw sizes and tightening torques, see chap. Technical data, from page 7. Higher tightening torques may cause fracture of screws or tearing of threads.
   Warning: Unsuitable screw connections may cause loosening of the NED by vibration. This can cause damage to persons and material.

3. Use an additional safety device for critical installation situations, e.g. steel cable NSE. Use the wire cable clamps to set the safety cable to the shortest possible cable length. The safety cable must always be tensioned.

Electrical connection

The following requirements and conditions must be met to connect the NED electrically:

• The electrical connection may only be carried out by authorized, qualified personnel.
  All work must be carried out exclusively with insulated tools suitable for the application.

• The permissible operating conditions must be met. Please refer to chap. Technical data, page 7 for operating conditions.

• The supply voltage must correspond to the information on the type plate.

• The permissible deviation of the supply voltage must be observed, see chap. Technical data, page 7.

• For the models NED 50100 up to NED 601510:
  It is imperative to pay attention to the correct polarity, because the NED will not start if the polarity is wrong.

• A suitable overload protection (1) must be pre-connected to each vibrator. The motor protection switches must be interlocked with each other in pairs, so that in the event of a motor failure, the power supply from both motors is interrupted at the same time in or- der not to cause uncontrolled vibrations which can damage the system.

• All electrical cables must be carefully laid and must be protected from high temperatures, lubricants and sharp edges. Care must be taken to ensure that the cables are not chafed through by vibrating parts. The correct condition of the electrical cables with their plugs must be checked at regular intervals (usually every six months). Detected errors are to be eliminated immediately.

• The wire ends must be fitted with suitable insulated cable lugs, in order to pre- vent the strands from splaying.

Note that the models NED 50100 up to NED 601510 have a start delay of approx. 1 second.

Start-up and operation

Observe the safety instructions in chap. Safety, from page 5 on.

Permissible operating conditions

Please refer to chap. Technical data, page 7 for permissible operating conditions.

Regulations

• When commissioning the NED, the rules and regulations of the local associations for electrical engineering (e.g. VDE) and the valid accident prevention regulations must be observed.
• The NED must always be switched on and off at the main switch.
• The NED must not be operated without the covers for the unbalances. The rotating unbalances cause a risk of injury.
• On initial start-up, the current consumption must be measured and must correspond to the specifications on the type plate.
• The terminal box cover must never be opened in the presence of voltage.

Note that the models NED 50100 up to NED 601510 have a start delay of approx. 1 second

Measures
Carry out the following measures before start-up:

1. Check that the NED have been mounted correctly and are in perfect condition.
2. Check that the NED have been properly connected.
3. Check that the cables are undamaged and laid according to the known regulations and standards.
4. Check that all permissible operating conditions have been observed.
5. Check that all protective measures on the system have been observed.
6. Eliminate possible errors before start-up.
7. Screw connections must be checked and, if necessary, retightened after 1 h operating time (after initial start-up) and thereafter regularly (generally monthly). Observe the recommended values for screw sizes and tightening torques, see chap. Technical data, from page 7.

Adjustment of unbalances

For all NED there is the possibility of unbalance adjustment to directly in- fluence vibration amplitude, centrifugal force and current consumption. Unless otherwise specified by you, the NED were delivered with the standard setting (100 %). If specifications have been made by the custom-er, there are stickers with the current setting on the unbalance covers.
Notice: The unbalances may only be set mirror- symmetrically!

Procedure:

1. Switch off the NED at the main switch, secure against unintentional starting and ensure that there is no voltage.
2. Loosen both unbalance covers.
3. Loosen the locking nuts or locking screws.
4. Bring the unbalances to the desired setting according to the following descriptions for the various unbalance discs. Note the mirror-symmetrical setting.
5. Retighten the locking nuts or locking screws. Observe the recommended tightening torques, see chap. Technical data, from page 7
6. Fasten both covers for the unbalances.

• For NED 5016: The two unbalance covers can be unscrewed using an oil filter/strap wrench.

Unbalance discs type XL

The NED has a total of 6 unbalance discs type XL.
The centrifugal force is adjustable with the unbalance discs (lamella) of type XL in the following steps:

1. Number of unbalance discs per side
2. Default number of unbalance discs per vibrator
3. Centrifugal force in %

There are 2 possibilities to adjust the unbalances:

1. The unbalance adjustment (fine adjustment) is carried out by removing one unbalance disc on each side. All centrifugal values in % can be adjusted as specified in the table.
   The removed unbalance discs must be replaced by compensation washers of identical thickness and identical inner diameter. These are available from NetterVibration.

2. The unbalance adjustment (coarse adjustment) is performed by turning one unbalance disc on each side by 180° on the shaft.
   Twice the number of unbalance discs turned by 180° becomes ineffective.

Unbalances type XLs

The centrifugal force is adjustable with the unbalance discs (lamella) type XLs. Adjustment of the unbalances is carried out according to a scale disc or the supplementary sheet in the terminal box of the NED.
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:
NED 50100 has a total of 6 unbalance discs (3 discs per side: 2 fixed, 1 adjustable).
If a centrifugal force of 88% is desired, the adjustable unbalance discs are rotated anticlockwise on both sides into the fourth grid position.

Unbalances type XN

The centrifugal force of the NED 601510 is adjustable with the unbalance discs type XN.
To adjust the unbalance, loosen the bolts with nuts on the unbalances on both sides. By turning the unbalance disc/ discs to another position, the percentage value of the centrifugal force changes according to the following figure.
After adjustment, fasten the bolts with nuts on both sides, with the recommended torque, see page 8.
