The installation of this rail-mounted device (9 HP, horizontal pitches) is envisaged in
distributor systems with common 35mm mounting rails (DIN rail) and covers with a 45mm
cut-out measurements. The wiring is connected via jack terminals in the lower and upper
device section (see Figure 1).
The Data logger is powered by an external 12V accumulator and can therefore work
independently from the mains. The accumulator is not part of the scope of supply.
It is also possible to power the logger with 24V AC/DC by means of a mains adapter.
A solar panel can be connected via separate terminals.
An integrated power management, fed by the solar input or the input for
24V AC/DC, charges the external 12V accumulator.
When the accumulator is disconnected, the clock is buffered by several hours with a buffer
capacitor.
Operation is guaranteed in a wide temperature range from -20° to 70°C.
The device can be simply operated by means of touch control directly on the display or via
the interfaces micro USB, Ethernet, COM1 and COM2. A colour LCD with 320 x 240 pixels
acts as a display.
The scanning of the measured values is configurable in the range from one second to 60
minutes. Pulses and frequencies are measured continuously.
The data is saved with time and date in accordance with the configured memory cycle (1s to
60 minutes) in a non-volatile Flash data store (64MB) (i.e. the data is retained even without
supply). The data store is designed as a so-called ring memory. Once the ring memory is full,
the oldest data set is always the next to be overwritten.
For the checking of the sensors or the measurement inputs, the Data logger can be switched
into the maintenance mode. In this mode, the sensor measured values do not go into the
memory. I.e. values determined during the maintenance mode are shown in the display as
usual, but are not taken into account for the calculation of memory values.
The data and/or measured values can be read out with the optional PC programme “Mevis”.
Note
The following DLL versions are necessary for the compatibility with the PC programme
“Mevis”:
DL16 Archive Reader DLL Version V1.17.0.0
DL16 FTP DLL Version V5.29.0.0
Note
The data logger can record a maximum of 100 measured values (channels)! Variables
derived from a measured value are also channels.

3 Installation
Attention
The device must only be installed and wired by qualified skilled personnel.
The generally valid codes of practice and the respectively valid regulations
and standards are to be adhered to.
3.1 Recommendation for Site Selection
The device is designed for installation indoors. In the case of outdoor use, an additional
enclosure with an appropriate protection class is necessary.
Note
Please consider the temperature area of application and protection class when choosing the
site
3.2 Mechanical Installation
The Data logger is designed for snap-on installation onto a normal 35mm mounting rail (Hut-,
TS35). The mounting rail must be at least as long as the housing width (157mm, 9TE).
Sequence:
•Install a 35mm mounting rail with a length of at least 9HP (157mm) at the installation
location.
•Place the data logger DLU on the mounting rail that the top edge of the rail grips into
the corresponding groove of the data logger DLU.
•Insert a screwdriver (blade width <4mm) into the slot of the clip and pull the clip
downward. The slot is located in the middle of the bottom edge of the housing.
•Press the Data logger DLU completely onto the mounting rail.
•Let go of the clip. The clip snaps in place behind the mounting rail.
•Check whether the housing is firmly fitted onto the rail, by light shaking.

3.3 Electrical Installation
3.3.1 Wiring
In order to build a low-noise (i.e. EMC-compliant) measurement system, the data and
measuring lines must be shielded. Thorough earthing of the shielding is to be ensured.
Depending on local conditions, a distinction is to be made between:
•Metal housing:
Shields of the lines contact directly to EMC cable glands.
•Plastic housing or no housing:
Produce shield connections via suitable rails or metallic installation plate with
appropriate clamps/adhesive bands (see Figure 2). The clamps must ensure large-
area contact to the cable shield.
Figure 3: Example of the earthing of the device

© Adolf Thies GmbH & Co. KG · Hauptstraße 76 · 37083 Göttingen · Germany 021821/08/21
Tel. [phone] · Fax [phone] · inf[email protected] ·www.thiesclima.com Page 13 of 102
The functional earth of the Data logger DLU (terminal 52) is to be connected with a 2.5mm²
cable (L <6cm) to an earthed shield rail or mounting rail.
For potential equalisation we recommend the use of the shortest possible cable (≤1m) with a
cross-section of at least 6mm² between metal housing and/or shield rail or mounting plate
and the protective earth (earthing strip or site equipotential rail).
Attention:
A voltage reversal of the connection lines can lead to the destruction of the device.
Lightning protection measures:
Especially when the device is used outdoors, the installation of additional protective elements
(surge arrestor, such as e.g. varistors) and additional network filters (for the 230V network) is
to be recommended.
3.3.2 Accumulator
When utilising the 24VAC supply input, we additionally recommend the use of an optional
accumulator (please see accessories). Ensure the following polarity when connecting (red =
+, black = -)!
Replacement or charging is necessary, at the latest, if the displayed voltage sinks below
9.0V. However, discharge of the accumulator under 11.0V should be avoided, because no
significant capacity is present any more. The service life of the accumulator is substantially
shortened by operation under 10.5V! The new accumulator should be “freshly” charged again
before installation, because by self-discharging (approx. 3% per month) it is possible that it
may no longer have its maximum capacity. The saved data is retained during changing. The
internal clock time is buffered for several hours. Before the accumulator is disconnected, the
data should be backed up. After connection, the Data logger starts the boot loader, which
starts the normal firmware after approx. 10 seconds.
Notes:
When changing the accumulator when the mains supply is switched on, it is to be ensured
that the red cable does not come into contact with the housing parts (short-circuit).
During installation it is to be ensured that all connections are switched to voltage-free and
that people and/or devices are not endangered!

3.3.3 Solar Panel
Electrical Connection:
The connection of the optional 12V solar panels is to be carried out in accordance with the
wiring diagram (see chapter 13). We recommend that the solar panel be earthed to protect it
against excess voltages. The integrated 12V solar controller carries out temperature-guided
control for optimal charging of the accumulator. The maximum power of the solar panel of
20W should not be exceeded, otherwise the controller could be damaged. Because of the
temperature control the accumulator should always be close to the Data logger.
Alignment:
•Direction: the solar panel is always to aligned to the highest solar altitude (south in
the northern hemisphere and vice versa) in order to receive optimal power. Use a
compass if necessary.
•Angle: the optimal angle of inclination (see Figure 3) is dependent on the latitude of
the site. If the Data logger is to be used throughout the year, we recommend an angle
of inclination for optimal performance in winter:
Angle of inclination = latitude + 15°
(Note: does not apply to Arctic regions because of maximum angle of inclination of
90°)
Example for Berlin: latitude 50.3° angle of inclination = 50.3° + 15° = 65.3°
Note:
A partial shadow caused by the structure or site, e.g. due to sensors or traverses attached
above the solar panel, must always be avoided.
Maintenance:
•Dust, snow, leaves etc. on the solar panel reduce the amount of light and the energy
yield deteriorates. For this reason, the solar panel surface should be cleaned if
necessary.

For the permissible load on the supplies, see technical data.
Note:
The configurable supply voltages are electronically protected against overloading (short
circuit) and overtemperature.
4 Operation
When the accumulator is connected, the Data logger automatically starts the so-called
bootloader (for the loading of new firmware) and re-initialises itself. The boot loader waits
10 seconds and then starts the current firmware automatically. After the first switching on,
the time and date on the display should be checked.
The colour graphic display (320 x 240 pixel, 24Bit RGB) possesses a resistive touch surface
via which the entire operation of the Data logger is performed.
All actions are carried out via touch events (pressing) on the symbols shows in the display.
The following table shows the available symbols (keys).
