Figure 2: Assembly with Sensor-Interface (9.1756.x0.100)
The datalogger DLx-MET is a complete measurement system serving for the acquisition and
storing of at minimum 10 meteorological parameters (e.g. temperature or radiation). Additionally in
the version 9.1756.x0.100 a so-called Sensor-Interface (SIF, see Figure 2) printed circuit board
with several measuring channels is connected to the serial interface COM2. Optional measuring of
other parameters or special sensors with serial output can be done by connecting the so-called
Sensor-Interface or a serial sensor to the serial interface COM2 or COM3 (RS485 2W, 2-Wire, halfduplex). The serial interfaces COM1 (used for commands and data output) and COM2 are
adjustable from operation mode RS232 to RS485-4W (4-Wire, full-duplex). See below Figure 3 for
a overview of all interfaces.

The instrument is battery-operated (12V), thus allowing it to be set up according to model and
sensor equipment at site without any mains supply for some hours or even days (applies not for
sensors measured by the Sensor-Interface). The exchangeable storage battery is situated in the
data logger case. With an optional 12V solar panel it is possible to load the battery.
Additionally a mains power supply (230VAC) can be used, which also supplies (24VAC) the heating
of sensors and the Sensor-Interface (apply only for 9.1756.x0.100). In this case the battery serves
for bridging in case of power failure. The following figure shows the supply possibilities.
Figure 4: Block diagram supply
In order to protect the accumulator against discharging the measurement of the sensors is
interrupted in case the voltage is below 10,5 V (thus the current consumption is minimized). Then,
6 - 56 021579/06/09
the voltage is measured every 5 minutes; when it is higher than 11,0 V the normal measuring
routine is continued.
An integrated lithium battery buffers the contents of the data memory and the clock operation when
no other power supply is available. This means that the saved values and the time are not lost even
when there is no additional power supply.
The housing can be locked, is impermeable to jet-water (IP65), and is a very stable construction.
For shielding against electromagnetic fields the housing is made of stainless steel. In addition,
operation is guaranteed for temperatures ranging from – 30 °C to 60 °C.
The instrument can be easily operated either by means of three keys, via serial interface COM1 or
via USB. The three keys are referred to in the following as"<∆>", "<∇>"ON, and "<ENTER>" (see
Figure 5). A three-line, alphanumeric liquid crystal display (LCD) serves as indicating instrument.

The scanning of the measuring values is selectable in the range from 1 second to 60 minutes. For
each of the 10 internal sensors the scanning, and further processing can be switched on or off
separately. The optional sensors connected to the Sensor-Interface are processed if the datalogger
receives a telegram over the serial interface COM2 (apply only for 9.1756.x0.100).
The measuring values are stored in a memory (CMOS-RAM) with a storing rate of 1 to 60 minutes
for mean values and 1 minute to 6 hours for extreme values. The memories are organized as socalled ring memory with a capacity of 1.4MB (mean) and 0.5MB (extreme) . If the capacity of the
ring memory is exhausted, the next step is to overwrite the oldest record. The reading-out of the
data can be carried out via the serial interface COM1, USB or via a Secure Digital Memory Card
(SD Card, see chap.5.2 for working types).
There is a so-called switch output available for the supply of an optional GSM-modem; by means of
this contact output the modem can be supplied at up to 6 selectable times a day.
It is possible to synchronize the internal time automatically by means of a separately connectable
DCF77-receiver module (reception range up to 2000km around Frankfurt(Main)/Germany).
For checking the sensors or the measuring inputs the datalogger can be turned into the
maintenance-mode. While this mode is active the measuring values of all the sensors cannot get
into the memory. I.e. values detected during the maintenance-mode are displayed, however, are
not taken into consideration for the calculation of mean- or extreme values.

2.1 MOUNTING
The datalogger is designed for wall-mounting or installation on a mast.
For proper protection against lightning strikes we strongly recommend to connect a preferably short
cable (≤1m) with a cross section greater than 6mm² between the case (see Figure 1, Grounding
Earth) and the mast (if used) with an earth terminal (e.g. grounding bound or main equipotential
bonding conductor). This connection is also necessary when mains (230VAC) is connected to the
datalogger.
It exists two case variants:
• 9.1756.10.x00x (case version A)
• 9.1756.00.x00x (case version B)
For the mast-installation of case version A seven different pipe clips with a diameter from 46 to
137mm are available. For mast-installation with case version B see chap. 2.1.2
8 - 56 021579/06/09
2.1.1 Wall-mounting
For mounting on a wall or likewise use the 4 mounting holes:
• diameter 10mm, see
• (applies for 9.1756.00.x0x)
• diameter 8.4mm, see Figure 7 (applies for 9.1756.10.x0x)

2.1.3 Cable gland
In order to carry out an EMC-compatible installation the cable screen (excepted the supply cable,
which is normally not shielded) is to be connected to the contact spring of the screwed cable gland
(see Figure 10) For wiring plan ref. to chap. 7.
1. With the Standard Contacting (see Figure 10-1)
- Strip back the outer sheath and screen (shielding)
- Make a round cut in the outer sheath approx. 15 mm along but do not remove the sheath
- Guide the cable through the cable gland
- Pull off the outer sheath
- Pull back the cable until the connection is made between the cable screen and contact spring
- Turn shut… and it is ready for use!
2. With thin Wires without an Inner Sheath (see
- Strip back the outer sheath
- Pull back the screen braid approx. 15-20mm over the outer sheath
- Insert the cables into the cable gland until the contact is made between the cable screen and
contact spring
- Turn shut ….and it is ready for use!
3. When Routing the Cable Screen to another Connection (see
- Expose the screen braid approx. 10 mm
-Guide the cable through the cable gland until the connection is made between the cable screen and
contact spring
- Turn shut…and it is ready for use!

2.1.4 Accumulator
The accumulator or battery is to be connected always. It is absolutely necessary to pay attention to
the specified polarity (red -> + ,black -> -)!
Remark:
When changing the accumulator, or with active power- or solar-supply please take care
that the red cable is not in contact with the housing parts (danger of short-cut)
During the installation please take care that all connections are voltage-free, and
that people and/or instruments are not endangered!
When replacing the accumulator with active power supply please take care that the red cable has
no contact with any part of the housing (danger of short-circuit).
A replacing or loading is necessary at the latest when the indicated accumulator voltage decreases
below 9.0V. However, a discharge of the accumulator below 11,0 V should be avoided, as no
considerable capacity is available any more. With operation below 10,5 V the life time of the
accumulator is reduced considerably! The new accumulator should be newly charged before
mounting, because, possibly, it might not have its maximum capacity due to self-discharge (approx.
3 % per month). The stored data are being secured during the replacement. Before disconnecting
the accumulator, the data should be saved. Without accumulator no measurements are being
carried out.
2.1.5 Mains supply
Safety Notes if using mains supply:
Attention! High Voltage. Mortal Danger!
The instrument must be mounted and wired only by qualified personnel, who
knows and observes the generalities of techniques, and applicable regulations
and norms.
Please keep in mind the local safety instructions.
Before carrying out any installation or service isolate unit from the mains supply!
in chapter 2.1.
When a Sensor-Interface(SIF, see Figure 2) board is installed (9.1756.x0.100), it is necessary to
swing open it to connect the 230V-power supply to the transformer or to check the fuses (see
Figure 1). When the both screws at the head of the SIF-board are removed you can turn the board.
When the 230V-power supply cable is installed, and connected, a red LED is active at the
datalogger between clamps 1 and 2 for the function control of the charging connection. In case this
LED does not light, the fuses of the 230VAC-input and the 16VAC-output of the transformer should
be checked.
13 - 56 021579/06/09
Additionally a red LED lights up between clamp 67 and 68 for control the 24VAC supply (normally
used for heating of sensors). In case of malfunction check the fuses 230VAC and 24VAC.
Remark for 9.1756.x0.001:
The 26Vac output has no fuse, but a 135°C thermal trip switch which breaks the
primary supply.
2.1.6 Solar panel
Electric Connection:
The connection of the optional solar panel is to be carried out according the wiring plan
(see chap. 7). We recommend to earth the panel for protection against lightning strikes.
The integrated 12V solar regulator generates a temperature-controlled voltage for a
optimum load of the battery. The maximum power of the panel should not exceed 20W,
otherwise the regulator could be damaged. Due to the temperature-controlling the battery
should be always in the case of the datalogger.
Alignment:
• Direction: Always align the panel pointing to the sun at noon (south on the northern
hemisphere and vice versa) for an optimum performance. If necessary, refer to a compass.
• Angle: The optimum tilt angle (angle between the horizontal plane and the solar panel, (see
Figure 11) depends on the latitude of the site. If the datalogger is to be used all the year
round, we recommend a tilt angle for optimum winter performance :
Tilt Angle = Latitude + 15° (apply not for Arctic / Antarctic region, maximum tilt angle 90°)
Example: Berlin(Germany) Latitude: 50.3° ---> Tilt Angle = 50.3° + 15° = 65.3°
Figure
11: Tilt angle for solar panel (here 45°)
• Nearby obstacles (trees, sensors etc.) should not block the sun at the panel.
Maintenance:
• Dirt, snow, leaves etc. on the panel reduces the amount of light and decreases the energy
yield. Therefore regularly clean the glass of the panel depending on the vicinity.
14 - 56 021579/06/09
2.1.7 DCF-Active Antenna (9.1760.00.000)
For installation of the optional DCF-Active Antenna (9.1760.00.000) it is necessary to notice the
following:
Generally, please take care that the position of the antenna is optimal. It should be aligned
horizontally to, and across the direction of the transmitter (situated near Frankfurt/M., N 50° 01’, E
09° 00’). The antenna should have a minimum distance of 1m from sources of interference such as
power lines, and a 20cm-distance from metal obstacles. For other information on the alignment of
the antenna ref. to chap. 3.2.7 .
2.1.8 Remove Front Plate
For changing or checking of the jumpers for the digital input (ref. to chap. 2.1.9) or for the resistors
of the serial interfaces (ref. to chap. 2.1.10) the front plate (see Figure 5) has to be removed.
First remove the 4 recessed head screws of the front plate. Then move the plate carefully because
otherwise the ribbon cable for the three keys can be damaged.
Before you tighten the screws check the 3 keys of the front plate. When the keys are not working
anymore you had to insert the ribbon cable into the 4-pin connector of the printed circuit board.
15 - 56 021579/06/09
2.1.9 Setting Digital Input
The digital input „Event / Length of time” (Sensor 10) can be configured for two possibilities with the
Jumper P2:
Jumperposition P2 Logic * Inverse Level Miscellaneous
2 3.3V(5V TTL) No Pull-up Resistor 100kΩ to 3.3V
3 1V Yes ** Resistor > 1kΩ
Table 2: Jumper for digital input
* The corresponding switching levels are listed in the technical data (see chap. 6)
** Note that with jumper in position 3 the logic level is reversed by the electronic.
The jumper P2 is situated 2 cm above clamp 13 (see Figure 12). To change or check the position it
is necessary to remove the front plate (see Figure 5, ref. to chap. 2.1.8).
Figure 12: Jumper for Digital Input
16 - 56 021579/06/09
2.1.10 Setting Resistors Serial Interfaces
There are three multi-pin connectors for the serial interfaces when used in RS485 mode. To get the
lowest current consumption and no negative impacts when COM1(P5) or COM2(P4) are in the
RS232 mode all respective jumpers must be open. COM1 and COM2 are adjustable by firmware
between RS232 and RS485 (ref. to chap. 3.1 Baudrate setting). COM3 is always in the operation
mode RS485-2w (half-duplex).
To change or check the position of the jumpers it is necessary to remove the front plate (see
Figure 5, ref. to chap. 2.1.8). Figure 13 show the position of the multi-pin connectors:
COM1: 10-pin connecter P5 (above the 9 pin D-plug)
COM2: 10-pin connecter P4 (above clamp 20)
