4 Safety
NTS vibrators work with
compressed air or nitrogen.
Make sure the compressed air or
nitrogen supply is switched off
during installation.
Disconnect the supply lines (quick
coupling) before starting other work
on vibrators and supply lines.
Before starting operation all hoses
must be tightly connected.
A pressurized hose coming loose
can cause severe injury.
Vibrator as well as part of the
structure can detach because of
vibration. Falling parts can cause
damage to persons and material.
Screw retention components and/or
Loctite or similar must be used.
Jan. / Feb. / ...
Screw connections must be checked and, if necessary, retightened after 1
hour of operation and then controlled at regular intervals (normally each
month).
In critical installation situations the unit must be secured with a steel rope.
Silencer:
Operation without silencer should
be avoided in order to protect the
environment against high noise
values.
Technical changes to the equipment may effect the characteristics of the
vibrators or even damage the units and cause the rejection of any
warranty claims.
Permissible operating conditions:
Operating pressure:
2 bar to 6 bar*
Operating pressures must not be exceeded or fallen short of.
Ambient temperature:
5°C to 60° C*
Operating temperatures must not be exceeded or fallen short of.
Lubrication:
If advised by application engineers of Netter GmbH and in compliance with
locally specified conditions, vibrators of group 1 may be operated without
oil. (Exception 1: In case of freeze-dried air and under extreme ambient
conditions, Exception 2: NTS 21/04).
Units of group 2 and the NTS 21/04 must only be operated with lubricated
compressed air or lubricated nitrogen.
*) Higher operating pressures and temperatures are only permitted after consultation and written confirmation by
application engineers of Netter GmbH.
