1. Construction of the Data Logger
The MeteoLOG TDL 14 data logger is a complete measurement system to detect and store meteorological data. The instrument is battery-operated, thus allowing it to be set up acc. to model and sensor equipment at site without any mains supply for some hours or even days. The exchangeable storage battery is situated in the data logger case. The case, which can be locked, is water-tight (IP65) and very sturdy. The case is made of stainless steel to protect the instrument from electro-magnetic fields. Furthermore, operation in a temperature range from -30° to 50°C is guaranteed.
The instrument is easy to operate, either with the three keys or over the serial interface. The three keys are indicated by "<
∆>", "<∇> on" and "<enter>" in the following. The instrument has a two-line, alphanumeric display.
Numerous inputs are available for the connection of measured data transmitters (sensors). A maximum of
10 analog and 4 digital sensors can be connected. The measured values are saved time-controlled in a
CMOS-RAM which has been secured against loss of data. This memory is organized as a ring memory and can save 256 KB. The data can be read out either over a serial interface (V.24/RS232-C or RS422) or over a memory card (option). The TDL14 with COM2 allows an additional output of the instantaneous data every second. The COM2 is not possible with the TDL14 with ultrasonic connection.
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.

2. Operation
The data logger starts automatically as soon as the storage battery is connected. The data logger is reinitialised during this process. Once the instrument has been switched on, first the clock and the date (see section 2.2.2) and then the measurement cycle (see section 2.2.3) should be set. Furthermore note the sensor settings and the language (see section 2.2.5).
The data logger has two data ring memories with a capacity of 256 KB. The ring memories can record data continuously i.e. when one of the ring memories is full, then the oldest data record is overwritten. The data ring memories can be read out over the serial interface or over a memory-card (option) (see section 2.3).
Switch the display on with key <
∇> (just press briefly). The data logger switches off automatically when no key has been activated over a period of 30 seconds or when no character was either transmitted or received over the serial interface. After the display has been switched on, the station name appears. Where "* " appears as the first character, this indicates that the user can change this value (see 2.2). The next display value is reached by pressing the <
∇> key. You can return to the preceding value with the <∆> key.

Inputting the station elevation is only of significance if an air pressure sensor has been connected to special input 5 (S4.5 = close, see 2.2.6).
Should you measure air pressure, then enter the station elevation here in order to obtain air pressure reduced to sea level (so-called "QFF").
When you enter station elevation 0 m, the sensor signal is output directly (air pressure at station elevation, so-called "QFE").
Elevations between 0 and 4000m can be set in consideration of the operation range from the air pressure sensor.

, baud rate, measurement cycle , memory cycle, extreme value cycle, channel configuration, radiation constant and station elevation.
To edit the displayed value, simply press <ENTER> and the <
∇> key. The value to be changed is indicated by the flashing cursor. Now release both keys. The value can be raised with the <
∆> or lowered with the <∇> key. If the set value is satisfactory, then press the <ENTER> key to leave the editing mode or to select the next variable.
Please note: To Change the channel configuration see chapter 2.2.7 on page 16.
2.2.1 STATION NAME
The station name is used to identify the measuring site. If several data loggers are in use, each of them should be given a different name. All letters and numbers as well as the underlining "_" and the space bar can be used for the name.
With serial data output, all 11 characters of the station name are output. For output onto a memory-card
2)
, the first seven characters are given.
When changing the station name the second line indicates the output language which can be selected through the arrow-key accordingly between “Deutsch “ or “English”.
2.2.2 DATE
If an invalid date is entered the computer automatically corrects it.
2.2.3 GSM-TIMER
TIMER X:HH:MM
ONLINE: NN min
X = 1,2,3
The GSM-Timer serves for activating a time window for a GSM-modem which is externally connected to a datalogger of the type 9.1740.xx.00x..
Through the setting of small time windows (<2 0 min) the medium current consumption of the modem
(operating current approx. 200 mA) per day can be kept at a low level.(see also example rection 2.6.2).
During the data transmission via a timer controlled mode the remaining switch-on period is kept on 5 min., in order to guarantee a re-query within this period in case the data query was incorrect.
In the editing mode the 3 time windows for the GSM-modem can be set one after the other. If the online time is reset and confirmed through the <ENTER>-key, the current and the following timers are deactivated.
„HH:MM“ gives the starting time of the current time window in the format „std:min“.
The ONLINE-time is selectable in minute-intervals: maximum online-time minimum online-time
:
:
60 min
5 min deactivate timer : 0 min
Remark: In case the accu voltage falls below 11 V, the GSM-modem is switched off in order to avoid a low-discharge of the accu!

The measurement cycle indicates the time intervals at which the analog and serial sensor values are measured by the data logger. The measurement cycle can be changed during operation without the preceding data being lost. The initial measurement interval set when the instrument is first switched on is 1 minute
1)
. All digital counting inputs (for example wind speed, precipitation) are continuously measured independent of the measured value set.
There are 23 different measurement intervals available: seconds: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 minutes: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Please note: The measuring cycle of a datalogger with COM2 or ultrasonic wind transmitter is set
permanently on 1 second.
The memory cycle indicates time interval for storing the measuring values. For this, the measuring values are averaged, or accumulated.
The memory cycle is selectable in 12 steps.
Minutes : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Example: meas. cycle 1 second memory cycle 10 minutes
A mean value is calculated from 600 measuring values, and stored. The calculation of the mean value is carried out as arithmetic mean with „normal“ sensors. Exceptions are the wind direction (vectorial mean), and precipitation (formation of sums)..
Please note: When changing the measurement cycle, the cycles of storing, and extreme values is
corrected automatically to an integer multiple.
The memory cycle influences the storing period of the mean values (ref. to section 2.7)
2.2.5 EXTREME VALUE CYCLE
The extreme value cycle gives the time point the extreme values are saved.

2.2.6 DIP-SWITCH SENSOR SETTINGS
Below the front panel of the data logger there is an 8-pole (S4) and a 4-pole DIP switch (S5) to configure a number of sensor settings. You can only read in the switch setting of S4 after you have switched the instrument on. Readjusting the switch during measurement operation has no effect, i.e. you should adjust the switch during measurement operation (display off) and then switch the data logger on with the on-key.
This makes the setting valid for the data logger.

2.3 DATA OUTPUT
The Datalogger provides two possibilities to read out the data:
- serial (V.24 / RS232 9.1740.xx.xx0)
(V.11 / RS422 9.1740.xx.xx1)
- memory card
1)
An external computer can be connected with an appropriate cable to the serial interface of the Datalogger to access the stored data. The transmission of all mean values stored in the memory takes at least 15 minutes at 9600 baud. Data transmission to a memory card
1)
is considerably faster (less than 2 minutes) because the data are transferred in parallel.
All data are transferred in ASCII format (text). This means that any text editing program can be used to examine, edit, manipulate and print the data. Accordingly you are able to conduct further data analyses with standard software, such as table format programs, data banks, etc..
2.3.1 SERIAL DATA OUTPUT
For the output of data over the serial interface COM 1, make sure that the memory card

Serial data output can follow by pressing the key or via cable.
We recommend that you use our communications program "Mevis" to read out the data. Moreover, you can use a standard terminal program (for example "TeraTerm" or "Terminal" from Windows).
2.3.1.1 CONNECTING CABLE OF THE SERIAL INTERFACE
The serial interface (COM1) is a "three-wire" connection. The transmission line (TxD) and the receiving line
(RxD) must be cross-connected in the cable.

2.3.3 DATA OUTPUT OVER MEMORY-CARD
2)
Output requires a memory card ("STARCARD" from ITT CANNON or compatible) with a memory capacity of at least 256 KBytes. The memory card should only be inserted into the holder of the data logger for read out.
SUGGESTIONS ABOUT USING THE MEMORY-CARD:
Battery-buffered static memories are used for data storage. Thus there must be a functioning battery in the memory card. The battery compartment is situated across from the contacts. To open the battery compartment, set the battery compartment lock to "UNLOCK" (use a tweezers or similar object). Now pull out the battery compartment. After returning the battery compartment to its original position, set the battery lock to "LOCK".
During transport and storage, make sure that the memory card is always in the anti-static cover!

21 - 30 020879/11/05
The nominal operational life of the battery of the 256 KB memory card (type BS256F1-C) is 4 years, thus when the memory card is not used for a longer period of time, it is advisable to remove the battery.
1. Switch the data logger on with the <
∇> key.
2. Insert the memory card into the data logger holder
3. Keep pressing the <
∇> key until the words "data output" appear on the display. Continue to press the

Selecting the memory output: "M" stands for mean values and extreme values
"E" for
Mean <
∇>
Extreme <
∆>
Please note: Mean values and extreme values can be stored in succession on the memory card.
Press <ENTER>: data output starts. Either "E" or "M" appears in the second line of the display, depending on what has been selected. In addition "MCard" and the number of data records output

Pressing the <ENTER> key interrupts transmission.
The end of the transmission is indicated in the display by ""end".
8.
9.
Remove the memory card from the holder.
Press <ENTER> to be able to operate the data logger "normally" again.
The memory card can be read out by a PC with a reading program and the corresponding reader (THIES accessories). The data format is set up in correspondence with the data lines in section 2.3.1.3. (The only difference: the data from the memory card always have only one space character as the separator.)
2.4 CHANGING THE STORAGE BATTERY
The storage battery, at the latest, has to be replaced when the indicated storage battery voltage drops below
9.0V. However, the storage battery should not be discharged below 11.0 V as there is no appreciable capacity available anymore. The operational life of the storage battery is considerably reduced when operated below 10.5 V! The new storage battery should be "freshly" charged once more as, owing to selfdischarge (approx. 3% per month), it may not have its maximum capacity. The stored data are retained during the exchange process. Before the storage battery is disconnected, the data should be secured.
Without the storage battery, no measurements are carried out. Before the storage battery is connected, press the <
∇> ON key and hold it down. After the battery has been connected and the key released once again, the data logger starts. No power is drawn from the buffer battery when the storage battery is connected (or when there is an external power supply); i.e. during this time, only the self-discharge factor is of importance for the operational life. The buffer battery can only be replaced by the manufacturer. When no power is drawn, the operational life of the buffer battery is 10 years.
Please Note: During installation it is important to make sure that all terminals are switched voltage-free and that individuals and/or instruments are not endangered!
22 - 30 020879/11/05
2.5 EXTERNAL POWER SUPPLY
2.5.1 DATA LOGGER WITHOUT TRANSFORMER (9.1740.x0.xxx)
The input for external power supply can be used to charge the storage battery and to supply the data logger with current. The terminal is situated below the cover plate for the sensor connections (pin 1 and 2).
The power supply must supply a current of at least 500 mA. The voltage range for direct voltage is 17 to
33 V DC and for alternating current voltage 14 to 24 V AC. Above pin 3 of the terminal there is a red lightemitting diode (LED). This controls the external power supply (LED lights up). The storage battery must always be connected. To switch the data logger on, first connect the storage battery. Then the external power supply can be switched on. Switch-off takes place in reverse order.
2.5.2 DATA LOGGER WITH TRANSFORMER (9.1740.x1.xxx/ 9.1740.x2.xxx/ 9.1740.x4.xxx)
The AC mains voltage on the transformer generates two low-voltages to supply power to the sensor heaters
(26 V AC) and to the data logger (16 V AC). We recommend a medium anti-surge 1 A-fuse (1 A mtr) to protect the mains voltage.
Please Note: The connection of protective earth PE to the transformer is absolutely imperative for safety
reasons!
2.5.3 DATA LOGGER WITH SOLAR PANEL (9.1740.x3.xxx/ 9.1740.x4.xxx)
The solar panel is connected over pin 3 and pin 4 on the terminal strip. In the integrated charge regulator in the data logger, the charging voltage changes with the temperature. That is why the storage battery should always be in the data logger case.
Please Note: The integrated regulator is designed for a solar panel with nominal data 12V/20W.
The use of a different panel could destroy the electronics!
General information of the solar panel:
Solar panels in use in the Northern Hemisphere should be aligned towards the South. For winter operation (with limited solar radiation) we recommend that you set an elevation angle adapted to the site (for Germany approx. 50°). Be careful that the arrangement of sensors or traverses above the panel does not cast shadows. Clean the surface of the solar panel as required (to remove snow, leaves etc.).
23 - 30 020879/11/05
As already mentioned in section 2.2.3, the current usage depends on the selected time intervals of data acquisition. It is necessary to differentiate between second and minute intervals
1)
, because two different processor modes are employed. In addition one must differentiate between the active phases of operation.
A GSM-mode that is switched-on and accu-operated, increases the current consumption considerably (min. operating current approx. 50 mA, data transfer approx. 200 mA). Therefore, in case of pure accu-solar operation the GSM-online periods should be brief
In the following we show how to calculate the current consumption for both modes of operation. Note that these calculations assume that the sensors are only switched on up to the time of data acquisition. However, some sensors must be in operation continuously (e.g. wind velocity sensors). For these cases the additional current consumption must be added to the calculated values. Furthermore, these calculations are only approximations due to the variable performance and ageing of the electronic components and the storage battery. The exact time intervals at which the storage battery needs to be recharged can be determined only by practical experience. The capacity depends greatly on the temperature: For operation below 0° assume only half the capacity.
For the data logger in mains-independent operation (only storage battery and solar panel), we basically recommend that you only set the measurement cycle to greater than or equal to one minute.
Due to the high current consumption of the ultrasonic a power-supply-independent operation with ultrasonic as wind sensor is not possible without additional external accu, and solar panels of appropriate dimensions.
2.6.1 QUERY SECONDS
Power consumption is composed of a continuously flowing current I cont
and a current which only flows together for approx 0.6 s for measurement of the sensors.
I cont
= ca. 50 mA (RS232 / V.24)
= ca. 55 mA (RS422 connect with Interface Converter)
The measurement current consists of a permanent component I query
and a current I sensor
which is dependent on the connected sensors. The total current I mean
can be calculated as follows:
Iquery + Isensor
Imean = Icont + * 0.6s
Measurement cycle [s]
EXAMPLE: Measurement cycle = 5 s, (RS 232-Interface)

= 18 mA

Operating life =
Current
EXAMPLE: Capacity 7 Ah
Current Imean = 56 mA

Operating life = = 125 h (ca. 5 days)
56 mA
Remark: The data logger 9.1740.xx.x1x (with COM2) operates only in a second’s cycle and needs approx.
55 mA. Approx. 30 mA for sensors result in a theoretical life period of approx. 82 h.
MINUTES
1)
As with QUERY SECONDS, power consumption is composed of a continuously flowing current I cont
and a current which only flows together for about 1.6 s for sensor measurement.
The current I cont
is lower than comparable current in query seconds by a factor of 10. Thus, query minutes is preferable in storage battery operation.
Icont = approx. 1 mA (RS232 / V.24)
= approx. 4 mA (RS422)
The measurement current, in turn, consists of a permanent component I query
and a current dependent on the connected sensors I sensor
.
Iquery = 18 mA
The total current I mean
can be calculated as follows:
Iquery + Isensor
Imean = Icont +
Measurement cycle [min] * 60s
* 1.6s * min
EXAMPLE: Measurement cycle = 1 min RS232-Interface
Isensor = 30 mA

2.7 MEMORY TIME PERIOD
The storage period is the period of time until the old data are overwritten. The data logger has two ring memories. The time period of the mean value memory depends on the memory cycle set. The time period of the extreme value memory depends on the extreme value cycle set.

2.8 CHANGING THE FUSE
If nothing appears on the display after you have pressed the on-key, this could mean that the fuse (situated above pin 6) has blown. (condition: storage battery not discharged).
To check whether this is the case, open the slide lock (press down and rotate towards the left) and remove the fuse. Check the fuse with a measurement instrument to test the flow of current (a visual check usually does not suffice!).
If the fuse is defective: exchange it for one of a similar type (100 mAT). If the data logger still does not go on:
Disconnect all sensor and serial connecting lines. Check the fuse again. If the data logger now switches on, then connect the cable one by one to the sensors until the fuse blows again to pinpoint the defective sensor.
Return the defective sensor to the manufacturer for testing.
If the data logger still does not switch on, return it to us for a check.
Please Note: The blowing of a fuse as a result of a direct or indirect bolt of lightning is a normal protective
function.
