contrast to multi-detector configurations, only one detector is
required here.
NaI detector NaI = sodium iodide crystal = scintillator
Scintillation detectors are very sensitive probes for gamma radiation.
Isotope Substance of the radiation source, e.g. Cobalt 60 (Co-60) or Cesium
137 (Cs-137).
Count rate Value for the number of pulses standardized to one second.
Background The count rate caused by the natural environmental radiation.
Cps Unit for the count rate: Counts per second.
1
Factory setting In the factory setting, all parameters are preset with default values.
In most cases, this makes calibration of the detector a lot easier.
Nevertheless, a calibration must always be carried out.
mSv Milli-Sievert: The unit indicates the dose rate (dose equivalent).
mrem Milli-rem (roentgen equivalent in man): traditional unit for the dose
rate (100 mrem = 1 mSv).
MBq Mega Becquerel: The unit indicates the activity of a source. Each Bq
corresponds to one disintegration per second, i.e. 1 MBq equals one
million disintegrations.
mCi Milli-Curie: Traditional unit for the activity of a source
(1 mCi = 37 MBq).
ATEX Atmosphère explosive: is used as a generic term for the ATEX Prod-
uct Directive 94/9/EC and the ATEX Workplace Directive 1999/92/
EC. The directives contain provisions for equipment and components for use in explosion hazardous areas.

CSA Canadian Standard Association: sets norms and standards that are
important for Canada (and America), among other things, the
Directive for Explosion Protection and Low Voltage.
PMT Photomultiplier or only multiplier: converts the flashes of light gen-
erated by the radiation in the detector into electrical signals.
HV HV = High voltage
The multiplier is operated at high voltage, so that flashes of light
can be converted into electrical pulses.
The high-voltage control allows for measurements that are stable to
temperature and aging. Each multiplier has a slightly different sensitivity, and must therefore be operated at a different high voltage.
active / passive (Source / Sink) Depending on the detector type, the current output can be config-
ured as a current source or current sink. The following terms are
used interchangeably:
• Current source: active / Source Mode
• Current sink: passive / Sink Mode

Volume 1 2 Proper Use
2 Proper Use
The measuring system SENSseries LB 480 is a detector which,
depending on its design, can be used for different measurement
tasks:
– Level measurement
– Monitoring limit values
– Density measurement
The measurement system is designed for the continuous monitoring
and detection of levels and limit levels of liquids and bulk solids in
bins, or to determine the density of liquids in tanks and pipes. The
proper use is defined in the project planning stage by BERTHOLD
TECHNOLOGIES, the system delivered may be used only for this
purpose.
If the detector is used in a way which is not provided for during the
project planning stage and which is not described in the User’s Manual, then the detector's protection is compromised and the guarantee claim becomes invalid.
BERTHOLD TECHNOLOGIES only accepts liability for / guarantees
the correspondence of the systems of the SENSseries LB 480 to its
published specifications. The detectors of the SENSseries may only
be installed in an undamaged, dry and clean condition. Alterations
and modifications to the system components are not allowed.
Repairs to the detector may only be made if expressly authorized
by the operating manual.

In gas atmospheres, when selecting group IIB or IIC for the intrinsically safe circuits, all intrinsically safe circuits and the LB 480
detector must be operated completely in the selected group IIB or
IIC.
Installation of the probe with protection level "ia" allows the safe
use of measuring instruments that otherwise may be used only in
zone 0 or zone 20.

5.6 Installation
• Observe the installation and safety instructions in the operating
manual.
• Install according to manufacturer's instructions and applicable
standards and regulations.
• Do not operate device outside of the electrical, thermal and
mechanical characteristics.
• Install the housing cover and the screwed fittings (cable glands,
adapters and sealing plugs) correctly to maintain the housing
protection.
• Unused entries must be sealed with metal sealing plugs.
• Please note also the operating and assembly instructions of the
screwed fittings.
• Evidence of intrinsic safety has to be provided prior to the
installation of intrinsically safe circuits (see IEC 60079-14).
The connection of measuring and test equipment must be considered! The installation must be carried out based on this
proof.
• Connect the electrical equipment to the local potential equaliza-
tion.
• With shielded cables, the shielding has to be placed on the
detector side. Observe an adequate insulation >500 V between
the screen and the lines.
• The current output and the open-collector circuit are each float-
ing and have a dielectric strength of at least 500 V
The circuit of the resistance thermometer is electrically connected to the PA port.
For the supply voltage the dielectric strength is at least 1500
.
V
eff
• Use a connection cable that is permitted and suitable for the
application conditions. Observe local regulations!
• The connection cable (conductor and insulation) must be suit-
able for a continuous operating temperature ≥ Ta + 15 K.
• Connected cables must be installed strain-relieved and fixed.
• Do not disassemble the detector housing from the detector
base (see Bild 5-6).
• Use the detectors exclusively for stationary installation.
• Devices that were used in "non Ex-areas" must not be used in
Ex-areas.
• The plan (checklist on page 1-53) for the control of the terminal
compartment has to be completed before commissioning and
every time the terminal compartment has been opened.

5.6.1 Increased Safety "e" in the Terminal Compart-
ment
Housing Cover • Take the weight (approx. 1.5 kg) of the housing cover into con-
sideration when open and closing it so that it doesn't smash
down.
• Install all four Allen screws (cylinder screws
ISO 4762 M5 x 20 - A4 - 70) for the housing cover with a
torgue of 4 Nm. Use spring washers (DIN 127 - B5 - 1.4310) for
housing covers with flat gaskets. For housing covers with
O-Rings, use Nord-Lock-washers (NL SS).
Screwed fittings • Use only metallic screwed fittings and M20 x 1.5 screwed fit-
tings suitable for the type of protection, depending on their
application, but at least IP65.
• Only screwed fittings are permitted for ambient temperatures
between -20° C and +40° C that technically meet at least the
standard listed on the cover page of LB 480 EC type-examination certificate. Only screwed fittings which have been
approved by BERTHOLD TECHNOLOGIES may be used outside
this temperature range.
• Use only cables and fittings approved in accordance with local
installation regulations. This could require special cables to prevent gas migration and, in particular, fittings with compound
filling.
• Use only screwed fittings that are suitable for the type of cable
(reinforced, non-reinforced, ...) and the cable cross-section.
• When using adapters for thread adjustment (e.g. thread reduc-
tion), only one adapter may be used in each cable gland.
1
• Replace the screwed fittings only by screwed fittings of the
same type.

Terminals • Permissible wire cross-section:
– with ferrules 0.5 - 1.5 mm2
(AWG 21 - 16 flexible)
– without ferrules 0.5 - 2.5 mm²
(AWG 21 - 14 flexible or solid)
• Both stranded leads as well as solid wires are permitted.
• To connect stranded leads, the following can be used: Ferrules
or direct insertion of the strand into the terminal.
The connection of fine-wire stranded lead class 6, according to
IEC 60228, is only permitted with ferrules.
• Install the connecting cables in the terminal compartment so
that ...
– dirt and moisture is avoided in the terminal compartment;
– the wires are not damaged when stripping.
– the conductor insulation or the collar of the ferrule extends
into the housing of the terminal body;
– bare conductive parts of the lines (e.g. small wires of a
strand) do not protrude from the terminal body;
– the length of the ferrule or the stripped wire must be 10
mm, so that the wire is securely held in the spring-type terminal;
– if ferrules are used, the conductor insulation extends into
the collar of the ferrule;
– clamped conductors and ferrules in the terminals must
comply with a pull-out test according to DIN 46228 for
1 minute:
30 N tensile force for 0.5 mm² cross-section and
50 N tensile force for 2.5 mm² cross-section
The crimped conductors in the ferrules must also pass this
tensile test.

5.6.2 Intrinsically Safe Installation Ex "i"
The sections "Screwed fittings" and "Terminals" in chapter 5.6.1
also apply to the intrinsically safe installation.
• The housing cover (metal lid) covers the entire terminal compartment (see Bild 5-3, top).
• Take the weight (approx. 1.5 kg) of the housing cover into consideration when open and closing it so that it doesn't smash
down.
• Install all four Allen screws (cylinder screws
ISO 4762 M5 x 20 - A4 - 70) for the housing cover with a torgue of 4 Nm. Use Nord-Lock-washers (NL SS).
• Seals of the screwed fittings must be designed in such a way
that the separation between intrinsically safe and non-intrinsically safe terminal room is not voided.
• The semicircular plastic cover (Ex-e cover) covers the
non-intrinsically safe terminals (see Bild 5-3, bottom).
• The Ex-e cover must prevent access to non-intrinsically safe
circuits with IP30 protection.
• After installation, the Ex-e cover must completely cover the terminal compartment for the power supply and RS485 interface
again.
• Both screws (flat head screw ISO 7045 - M3 x 8 - 4.8) for fixing
the Ex-e cover must be mounted.
• The housing cover is mounted correctly only if the pin on the
Ex-e cover smoothly clicks into the blind hole of the housing
cover.
• With intrinsically safe versions
– the metal cover to the terminal compartment may be
opened only for a short time for testing and adjustment.
– the semicircular cover in the terminal compartment may be
opened only if the terminal compartment is no longer energized and no explosive atmosphere is present.
• Devices with intrinsically safe circuits must not be connected to
intrinsically safe circuits any more if they have not been used
intrinsically safe before.

The paragraph "Terminals" in chapter 5.6.1 is also valid in this
chapter.
• The threads (cable entries 1/2" NPT and housing cover) must
be protected against damage.
• The threads (cable entries 1/2" NPT and housing cover) must
be protected against moisture and corrosion. Therefore always
lubricate the complete thread with grease OKS 217 in order to
achieve the degree of protection NEMA Type 4X.
Housing Cover • Take the weight (approx. 1.5 kg) of the housing cover into con-
sideration when open and closing it so that it doesn't smash
down.
• Fix the housing cover thoroughly (>10 turns), til the O-Ring is
covered. Tight the housing cover with a torque moment of
25 Nm.
Cable Glands • Ony use metallic cable glands with 1/2" NPT thread.
• Only use cable glands that correlate to the local valid standards
and legal regulations.
• When using conduits, install sealing boxes direct at the cable
entries.

Visual inspection Carry out regular visual inspections of the SENSseries measuring
system, at least once every three years. To do this, use the visual
inspection plan in chapter 5.8.1. Take appropriate actions immediately if you detect damage in the course of the visual inspection; if
necessary, disconnect the detector from power supply immediately.
To determine the inspection intervals for the visual inspection, take
the following conditions into consideration:
• ambient conditions (temperature, humidity, corrosive atmosphere, shock and vibrations)
• operating conditions (degree of utilization, operating errors)
• major changes in the overall system (e.g.changes in zoning)
Seals If the cover or the housing is opened, check the respective seals and
replace them, if necessary.
Cleaning Take care not to damage the cable glands and the type plates
during cleaning. Remove coarse debris with a stainless steel wire
brush. Grinding, filing or chipping away deposits with the hammer
is not permitted.

6 Electrical Installation
The electrical installation may be carried out only by a qualified
electrician.
Electrical hazards
Risk of fatal injury due to electric shock!
Open the housing only to perform installation, maintenance and
repair work.
When the housing is open, you may come into contact with live
parts if the power supply is connected. During installation and
maintenance work on the hardware of the detector you have to
switch off the measuring system, possibly connected relay contacts, and all the inputs and outputs in order to avoid contact with
live parts.
Never modify the installation without having thoroughly read this
User’s Manual.
1
Cable glands, adapters and
dummy plugs
The screwed fittings must be suitable for the intended use (ATEX or
FM/CSA).
If the detector is not used in explosion hazardous areas, the
screwed fittings, adapters and dummy plugs have to be tested in
accordance with at least one of the following guidelines or standards:
– EN50262
– UL1565
– C22.2 No. 0.17.92
–ATEX
At ambient temperatures of -20 to +40° C, only metallic cable
glands and metal adapters may be used to comply with the protection class IP 65. The material properties of the cable glands, adapters and dummy plugs used must be suitable for the ambient conditions existing at the measuring location.
At ambient temperatures above 40° C and below -20° C, only the
cable glands tested and approved by Berthold may be used.
The tightening torques for the cable glands supplied by BERTHOLD
TECHNOLOGIES are listed on page 1-47.
Please note that only one adapter per cable entry may be used. It
is not permitted to screw together several adapters.
The total length of the cable glands, including any adapter must not
exceed 10 cm.

IMPORTANT
Cable conduits that are not used must be closed by suitable, metallic dummy plugs.
Special cable glands are required for reinforced cables. The cable
assembly is described in the installation instructions of the cable
conduit used.
In case of doubt, we recommend using screw fittings, dummy plugs
or adapters by BERTHOLD TECHNOLOGIES.
Cables and wires Only use cables with diameters that are permitted for each cable
gland. The cables must have the following wire cross-sections:
–Power cord: 1mm
– Signal lines: 0.5mm2 to 2.5mm
The cables used must be suitable for at least a temperature which
is 15° C above the maximum ambient temperature.
The cables must not be subjected to tensile stress, but have to be
installed strain-relieved. We recommend creating a cable loop in
front of the entry of the housing.
If there is a danger that the cable may be used as a stepladder, then
the cables must be installed protected, for example in conduits. Also
make sure that the cables that are connected to the detector are
laid without abrasion or kinks.

Stranded lead The ends of multi-strand wires or fine wire lines (strands) may not
be tinned or soldered. Permitted variations are ferrules and direct
connection of the strand.
When installing fine wire lines in a terminal, individual wires often
get stuck at the edge of the terminal, are then pushed back and in
the worst case project over the insulated edge of the terminal.
Therefore, make sure that all multi-wire or fine wire lines are covered by the terminal and are clamped inside the terminal.
Grounding conductor The grounding conductor has to be connected to the terminals
marked with PE. With interconnected detectors (multi-detector
operation) the PE may not be looped from one detector to another.
Therefore supply lines with PE have to be guided in a star-shaped
pattern from one terminal box to the individual detectors.
Potential equalization Connect the detector to a equipotential busbar on site. The line on
this bar must be as short as possible.

IMPORTANT
Separator A separator
– must be present (regulation according to EN 61010-1)
– must be easily accessible for maintenance personnel
– has to be included in the company's internal documentation
It can be installed in the form of a circuit breaker or as a switch and
must meet the requirements of IEC 947-1 and IEC 947-3. If a fuse
is used, it must trigger only at a current of greater than 4 amps per
unit.
General points that are important for installation
Open the terminal compartment in dry ambient conditions, not in
the rain.
Moisture in the terminal compartment can both cause a short circuit with other lines or cancel the explosion protection.
• Please follow the signs on the detectors.
• Connect the cables with special care.
• The connecting cable and its installation must comply with
applicable regulations.
• Make sure when installing the cables that mechanical damage
to the conductor insulation from sharp edges or moving metal
parts will be ruled out. If necessary, install the cable appropriately protected, for example in conduits.
1
• Install the connecting cables in the terminal compartment so
that
– dirt and moisture is avoided in the terminal compartment;
– the wires are not damaged when stripping;
– the conductor insulation or the collar of the ferrule extends
into the housing of the terminal body;
– bare conductive parts of the lines (e.g. small wires of a
strand) do not protrude from the terminal body;
– the length of the ferrule or the stripped wire can be 10 mm,
so that the wire is securely held in the spring-type terminal;
– if ferrules are used, the conductor insulation extends into
the collar of the ferrule;
– the minimum bending radii permitted for the respective
cross-section are not fallen below;
– install the cables strain-relieved and without abrasion.
• The SENSseries detectors may only be operated with fully
closed housing.
• Cleaning corroded threads at the cable glands or cable conduits
using abrasives or a wire brush is not allowed.

7.5 Project Planning
7.5.1 Safety Function
The measuring system SENSseries LB 480 is used for non-contact
measurement of level, density or concentration. A gamma radiation
source (Co-60 and Cs-137) generates a radiation field which is
attenuated or absorbed by the product to be measured and is
detected by the scintillation detector LB 480.
The following descriptions are exemplary for the respective application. The safety integrity, that is the non-detected measured value
deviation is <2%. If TowerSENS detectors are used the deviation is
<5%. Information on the accuracy of the measurement can be
found in the technical data section of the operating manual.
7.5.1.1 Level detection
The measuring system consists of a detector and a radiation source.
These are mechanically positioned on the filling level and trigger an
alarm once this level is reached. The safety function is to monitor
the fill level of the product to be monitored at a defined fill level.
This can be both an overfill and underfill protection.
Principle of measurement As long as the level is below the beam path, the detector receives
radiation from the radiation source and the signals "Empty". If the
level rises and reaches the height of the beam path, then the radiation is absorbed by the product. The significantly reduced radiation
intensity evaluates the detector signal as a "Full" signal.
The "Empty" signal is displayed on the analog current output with
4 mA, the "Full" signal with 20mA.

7.5.1.2 Level measurement
The measuring system consists of a detector and a radiation source.
Both the detector and the radiation source may be designed
rod-shaped or point-shaped. These are mechanically positioned so
that the desired measuring range can be covered. The safety function is to monitor the fill level of the product to be monitored within
the measuring range.
Principle of measurement As long as the level does not reach the area of the beam path, the
radiation arrives unhindered at the detector. Once the level is within
the measuring range, part of the radiation is absorbed. This reduced
radiation intensity is indicated at the detector as rising level. The
more the level rises, the more the radiation is reduced, which the
detector signals as a continuous level increase from 0 to 100%.
1
The level change from 0 ... 100% is represented by the analog current output 4 ... 20mA.

7.5.1.3 Density measurement
The measuring system consists of a detector and a radiation source.
These are mechanically positioned such that the beam path runs
through the product in order to detect the product density. The
safety function is to monitor the fill level of the product to be monitored within a defined density measuring range.
Principle of measurement A higher product density reduces the radiation intensity at the
detector. A lower product density increases the radiation intensity
at the detector. The change in radiation intensity is output in the
detector as a continuous signal within the measurement range.
The detector signals the change in density via the analog current
signal. The lower measuring range of the density corresponds to
4mA, the upper range corresponds to 20mA. The PT100 may be
used for temperature compensation.

7.5.2 General Notes and Limitations
• The user-specific limits must be observed and the technical
specifications must not be exceeded. See operating instructions.
• The container geometry on which the source-detector calculation is based must not differ from the one at the mounted measuring point. If there are any deviations, please contact
BERTHOLD TECHNOLOGIES.
• Only the analog 4-20mA current output signal may be used for
safety functions.
• The measuring signal may only be used by the control system
when the Safety Mode is enabled.
• The RS485 interface must be used exclusively for the master-slave communication.
®
•The HART
• If there are magnetic fields in the immediate vicinity of the
measuring point, then you have to make sure through appropriate tests that the magnetic field intensity does not affect the
measuring signal.
• Use only radiation sources with the isotope Co-60 or Cs-137.
• Only shieldings made by Berthold may be used.
• During operation, the source shielding may not be

• It must be prevented that no additional absorber (e.g. steel
plates) get into the beam path, which were not considered for
commissioning.
• Any influence of adjacent radiometric measuring points should
be avoided. If in doubt, the measuring point arrangement has
to be discussed with BERTHOLD TECHNOLOGIES.
• Several detectors may be interconnected into a multi-detector
system. In an interconnection, only one detector may be configured as a master detector.
• In a multi-detector system, the time constant must be
> 2 seconds.
• The user is responsible for the validation of the safety function.
• The following types of detectors can only be used when all
count rates within the measuring range are above 1000 cps.
– LB 480-13 (CrystalSENS 40/35)
– LB 480-14 (CrystalSENS 40/35 with water cooling)
– LB 480-15 (CrystalSENS 25/25)
– LB 480-16 (CrystalSENS 25/25 with water cooling)
These detectors can be operated only with detector code "0".

• Detector code "1" has to be used for the following types of
detectors: when count rates of less than 1000 cps may occur
within the measuring range. In the other case detector code "0"
can be used.
– LB 480-11 (CrystalSENS 50/50)
– LB 480-12 (CrystalSENS 50/50 with water cooling)
• The error current (Loop Alarm Type) has following setup
options:
– High: >21mA
–Low: <3.6mA
7.5.3 Assumptions
The evaluation of the measuring device according to functional
safety aspects is based on the following assumptions:
• The failure rates are constant over the lifetime.
• The environmental conditions correspond to an average industrial environment.
• The repair time (replacement of the measuring system) after
an interference immune error is 72 hours. (MTTR
• The maximum operating time is limited by the average count
rate and the scintillator used:
1
= 72h).

7.5.3.1 Determination of the Failure Rates
The failure rates of the device were determined by an FMEDA
according to IEC61508. The calculations are based on component
failure rates according to SN29500. All numerical values refer to an
average ambient temperature during the operating time of 40° C
(104°F). For higher temperatures, the values should be corrected:
• Continuous operating temperature 50 … 60° C (122...140°F)
by a factor of 1.3
• Continuous operating temperature 60 … 70° C (140...158°F)
by a factor of 2.5
• Continuous operating temperature 70 … 80° C (158...176°F)
by a factor of 4.5
Similar factors apply when frequent temperature fluctuations are
expected.

7.6 Device Behavior during Operation
7.6.1 Device Behavior after Power On
After power on, a diagnosis phase of 15 seconds starts in which the
measuring device is checked for errors. The current output changes
to 24mA for 2 seconds and then to 0mA. During this time, no communication with the device is possible.
If an error is detected during the diagnosis phase, the device
changes to fault current. In the other case, a current in the range
between 3.8 ... 20.5 mA is output.
7.6.2 Behavior of the Current Output in Case of
Error
If the measuring device detects a fault, the current output is
brought to a safe condition.
Error >21mA or <3.6mA:
There is a hardware or software error.
Please refer to the operating manual for a detailed description of the
error behavior.
7.6.3 Device Behavior in Case of Interference Radia-
tion
The LB 480 is able to detect interference radiation caused, for
example, by weld seam testing. If interference radiation is present,
the measured value switches to fault current for the wait time set
in the device. Overfilling or underfilling cannot be detected during
this time. Even if the LB 480 is very sensitive when it comes to the
detection of interference, one cannot rule out ultimately that specially low interference radiation influences may not be detected and
the measured value is falsified. For this reason, it is generally necessary that the system operator is informed in advance and appropriate measures are taken to maintain the safe operation of the system.
7.7 Installation and Wiring
Installation and wiring is described in the relevant operating
instructions.
If necessary, the following inputs can be connected and used:
• Pt100 for temperature compensation
• RS485 for cascading as a multi-detector system
The use of other inputs is not permitted in safety-related applications.
