*) Underwater operation requires air discharge to the atmosphere.
The air supply is located on the side
of the housing (imperial thread). Do
not use fittings with threads longer
than specified (see table) e.g. no tubes with male
thread. The housing may thereby be deformed –
the piston will seize.
The compressed air supply must be
securely fastened.
The air is discharged via the silencer.
The housings have a metric mounting thread in
the base.
Start-up and Operation
The start-up of the vibrator is possible
immediately after the correct installation.
Make sure that the pneumatic system is able to
supply the air quantity specified in the operating
instructions. Otherwise the vibrator will not be
able to reach the technical specifications.
Permissible operating conditions:
Ambient temperatures
The permissible temperature range
of 5°C to 60°C must not be
exceeded or fallen short of during
operation.
At ambient temperatures ≤ 10°C higher start-up
pressures may be required (≥ 2 bar).
Ensure that the compressed air supply system
is able to meet the air consumption value
specified in the detailed operating instructions.
Otherwise the vibrator will not be able to
achieve the technical specifications.
Amplitude adjustment:
The amplitude of vibration can be adjusted by
regulating the exhaust air using an optional
throttle. The exhaust throttle can be mounted
directly to the vibrator or integrated in the air
discharge line.
Checklist for Assembly and start-up:
1. Install the unit carefully.
2. Secure the fastening screws.
3. Install maintenance unit (filter, regulator),
valve and supply line.
4. Install lubricator and adjust oil flow (2 to 6
drops/h).
5. Check: Are fastening screws secured?
6. Have notes on hose length and nominal
width been observed?
Maintenance
NTS vibrators can be cleaned with a water jet
from outside. Then operate the vibrator for a
short while after.
Dirty compressed air causes
clogging of filter and silencer.
If necessary empty the filter, clean
filter element and silencer (wash out).
The use of a mist lubricator requires that it works
correctly (are the contents decreasing? drops/h?).
Top up oil regularly.
Screw connections must be checked
and retightened after 1 hour of
operation and then at regular inter-
vals (normally every month).
For maintenance instructions and trouble shooting refer to the operating instructions.
Waste disposal: The parts must be disposed
off according to valid regulations, depending on
the material.
All units can be disposed of through your
supplier. The valid waste disposal prices are
available on request.
