The DuoSeries detectors differ in their external dimensions and the scintillators
used. Point detectors are equipped either with a 50/50 (diameter x length) NaI scintillator or a 50/60 polymer scintillator. Polymer scintillators are used in the rod detectors (models are available with the sensitive lengths of 500 mm, 1000 mm, 1500
mm and 2000 mm). The size of the scintillator determines the size of the sensitive
area (the area that is used for the measurement). Marking grooves (Fig. 3) on the
detector housing mark size and position of the sensitive area.

4.5 Installation on a Vessel
For mounting the detector on the vessel, the mounting clamps must first be
mounted on the detector (see chap. 4.3). Examples are shown in Fig. 8, Fig. 9 and
Fig. 10. Appropriate mounting fixtures (e.g. mounting brackets, platforms, etc.) are
to be provided by the operator. The dimensions of the detector and the mounting
clamps (see Appendix) should be observed. The orientation of the system components (radiator/shielding and detector) to each other and to the measuring range
is described in detail in the operating manual of the corresponding transmitter.
The cable bushing and cable inlet should be positioned so that no water can flow
along on the cable into the bushing.
The distance from the middle of the detector to the vessel surface or surface of
heat insulation should be approx. 100 mm.
Care should be taken during mounting to avoid as far as possible heat transfer
from the vessel via the clamps to the detector.

7.1 System Events
A list of all possible device event messages with troubleshooting options is provided below. Event messages are automatically hidden if the cause of the event is
no longer present. Exceptions are marked in the list. In this case, the event, as described in chapter 6.4.7, must be manually acknowledged.
System events can lead to the following system statuses:
• Shutdown
• Failure
• Out of Specification
• Function Check
Shutdown (Namur107: F)
A critical error has occurred. The detector will shut down to prevent damage. The
measurement is stopped.
Failure (Namur107: F)
A serious error has occurred and the accuracy of the measurement results is not
ensured. The measurement is continued.
If the detector is operated with an LB 44x/LB 471 transmitter, then the count rate
is set to 0 by the system status "Failure" in order to signal the system status. In this
case, the measurement is interrupted.
Out of Specification (Namur107: S)
The detector, one of its components or the environmental conditions are not
within the normal specifications. The measurement is continued.
Function Check (Namur107: C)
Indicates that entries are made at the detector or a function check/simulation is
being performed.

Errors on the scintillator and/or photomultiplier manifest themselves by a too small
or too steep plateau (see chapter 6.4.5). Such errors can often already be recognized in a visual inspection. To do so, the scintillator and the photomultiplier must
be disassembled.
The scintillator has to be crystal clear on the inside and neither have any cracks nor
dull spots. A clear yellow to brown discolouration indicates a thermal overload and
requires replacing the scintillator.
The window of the photomultiplier has a deposited film as a photocathode. This
layer causes the window to have a slightly brownish or smoked glass colour. If this
layer is no longer present or is stained, the cathode is damaged (e.g. through overheating, broken glass or light). In this case, the multiplier has to be replaced.

9.1 Water Cooling System
To protect the scintillators against overly high temperatures, a water cooling system is optionally available. A water cooling system must be used if the detector
temperature may exceed +60 °C.
In this respect, ambient temperature, sun light, radiant heat of hot components
and the transition of heat from installation fixtures should be considered. With
water cooling, the detectors can be operated at a maximum ambient temperature
of 100 °C.
For the minimum cooling water requirement, please refer to the document technical information.
When operating in areas with danger of explosion, observe the specific ambient
temperature limits, which are specified in the safety manual and in the document technical information.
If water remains in the water cooling systems at ambient temperatures below
the frost point, the cooling water system can be damaged.
u If there is a risk of frost, empty the water cooling system.
If there is a risk that the maximum operating temperature is exceeded, the cooling water circuit must remain in operation even if the detector is switched off.
A failure of the cooling water system or an insufficient flow can overheat the
detector and thereby cause damage. For cooling, exclusively use water of drinking water quality.
