3.1Configuration
The scope of delivery encompasses:
lLock fitting ARV-TF633.2for KSR-TF 633 vibrating level
switch
lDocumentation
-this operating instructions manual
3.2Principle of operation
ARV-TF633.2is a pressure-tight threaded fitting up to 16 bar
(232 psi)and can be used together with a level sensor in tube
version (KSR-TF 633). The tube version of the sensor must
have a diameter of 21.3mm (ø0.84 in).
ARV-TF633.2cannot be used in coated tube extensions.
The wetted parts of the ARV-TF633.2are made of steel
(316L).
With the lock fittings,sensors with tube extension can be fixed
infinitely.
The pressure screw of the lock fitting compresses a graphite
gasket consisting of three rings axially which is then pressed
radially to the tube of the sensor.If mounted correctly,the
graphite gasket encircles the tube tightly.The clamp protects
the tube against sliding through.Alocking bracket protects the
terminal screws of the clamp against unauthorised or
unintentional loosening.
3.3Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly,recyclable cardboard.For special versions,PE
foam or PE foil is also used.Dispose of the packaging material
via specialised recycling companies.

4Mounting
4.1General instructions
The note of the following general safety instructions:
lDismount the lock fitting only in unpressurized condition
lUse only suitable graphite gasket rings.Make sure that the
graphite gasket rings are not damage.Damaged rings are
no longer tight.If you are not sure,use new rings.
lOnly use approved hexagon screws DIN 912 M6x25 of
A4-70 according to AD leaflet W2.The corresponding
spring rings B6must be made of A4according to DIN 7980.
lGrease the thread and the support of the terminal screws
with a suitable lubricant.The lubricant must be suitable for
material combination 316L/316Land for a temperature
range of -50 …+250°C(-58 …+482°F)e.g.Varybond
type NSS-16/7.The threads are already supplied with a
lubricant.
4.2Mounting sequence
The lock fitting is already premounted.
The numbers in brackets refer to the following illustration.
1Loosen the screw (6)and remove the locking bracket (4)
2Screw mounting boss (7)with a resistant seal ring into the
thread of the vessel and tighten the mounting boss (7)on
the hexagon (SW 41 or SW 60)
3Clean the connection tube of the sensor and the surfaces
of the clamp (1)as well as the pressure screw (11)
carefully and remove grease,oil and dirt.Insert the sensor
into the lock fitting.Slide the tube into the requested
position and hold it
4Make sure that the sensor is in the correct position (height).
The height adjustment of the sensor determines also the
switching point
5Tighten the pressure screw (11)with a torque 70 ±10 Nm
(51 ±7lbf ft)
6Continue to turn the pressure screw (11)clockwise until the
hexagon surfaces of the pressure screw (11)and the
mounting boss (7)correspond (max.1/6turn)
6Lock fitting ARV-TF633.2--pressure range:-1…16 bar
Mounting
32042-EN-060620

7Tighten the terminal screws (3)alternately.Make sure that
the gap between clamp and pressure screw is in parallel.
Tighten the terminal screws up to a torque of 3±1Nm
(2.2±0.7lbf ft).
Hence the clamp (1)is pressed against the tube and fixes
the tube of the sensor in this position
8Fasten the locking angle (4)with the hold screw (6)and the
spring ring (5)laterally on the pressure screw (11)
Hence the pressure screw and the terminal screw are
secured against unintentional loosening

5Maintenance and fault rectification
5.1Maintenance
When used as directed in normal operation,lock fitting ARV-
TF633.2is completely maintenance-free.
5.2Exchange seals
If you want to loosen the lock fitting,e.g.to change the
switching point,you have to exchange the graphite gasket
rings.
The numbers in brackets refer to the illustration under
"Mounting".
Danger:
Before dismounting,make sure that the vessel is unpressur-
ised
1Loosen the screw (6)and remove the locking bracket (4)
2Loosen pressure screw (11)
3Hold the tube of the sensor and loosen the terminal screws
(3)
4Pull the sensor out of the lock fitting
5Unscrew the pressure screw (11)out of the mounting boss
(7)
6Screw the mounting boss (7)with a new resistant seal ring
into the thread of the vessel and tighten the mounting boss
(7)on the hexagon (SW 41 or SW 60)
7Unpack the new gasket and graphite gasket rings.The
graphite gasket ring (9)is thin;the gasket rings (8)are a
little thicker and have a layer configuration.
Make sure that the rings are not damaged.If you are not
sure,use new rings.
8First of all place one of the new gasket rings (8)into the
mounting boss (7). Then place the graphite gasket ring (9)
on top.This is followed by the second gasket ring (8)
9Place the pressure ring (10)of metal to the gasket rings
10 Screw the pressure screw (11)with a view turns from top
into the mounting boss (7)

11 Clean the connection tube of the sensor and the surfaces
of the clamp (1)as well as the pressure screw (11)
carefully and remove grease,oil and dirt.Insert the sensor
into the lock fitting.Slide the tube into the requested
position and hold it
12 Make sure that the sensor is in the correct position (height).
The height adjustment of the sensor determines also the
switching point
13 Tighten the pressure screw (11)with a torque 70 ±10 Nm
(51 ±7lbf ft)
14 Continue to turn the pressure screw (11)clockwise until the
hexagon surfaces of the pressure screw (11)and the
mounting boss (7)correspond (max.1/6turn)
15 Tighten the terminal screws (3)alternately.Make sure that
the gap between clamp and pressure screw is in parallel.
Tighten the terminal screws up to a torque of 3±1Nm
(2.2±0.7lbf ft).
Hence the clamp (1)is pressed against the tube and fixes
the tube of the sensor in this position
16 Fasten the locking angle (4)with the hold screw (6)and the
spring ring (5)laterally on the pressure screw (11)
Hence the pressure screw and the terminal screw are
secured against unintentional loosening
