Specifications for the Download
It is possible to transfer the data concerning the temperatures to be filed (by means of a PC or printer) by utili-
zing an appropriate module connected to the Datalogger: the Carel Download module (code DLOGSER000).
If this does not happen, after a period of time higher than one year, the Datalogger begins the overwrite of the
old data in order to place the new ones (see the mask" Available storage" in the "INFORMATION MODE").
The dumping of the data takes place through a telephone dial. Once the serial connection has been establi-
shed, press simultaneously the and

All data log.
When pressing the button the transfer of the data recorded by the previous Download starts.
When pressing the button the Download of the whole storage starts. If the buttons have been pressed
before connecting the Download module, the following warning appears on the display:
Connection fail.
If, on the contrary, the connection has already been carried out during the button pressure, the transmission
starts immediately. The Download operation starts after an acoustic signalling and the mask below appears:
Downloading...
25 %
The percentage indicates the fraction of data already transferred. If the operation is carried out correctly it will
be possible to read the following message:
Download OK
otherwise, if for instance there is no more place in the storage of the Download module (where the data are
being dumped) or an error has occurred in the connection or something else, the following message will appear:
Download failure
The Download operation ends after an acoustic signalling. Being in the Download mode, it is possible to go to
the other modes (for example, to check possible new alarms) by pressing the relevant buttons. In this case
the user will be informed on the state of the Download by an arrow on the right bottom corner of the display.
By pressing the two and buttons as long as the arrow is present, it will be able to return into the
Download mode and display the mask relevant to the phase being reached by the data transfer. When being
in the Download mode, the temperature sampling is in any case active.

Example of data print by Download (table print)
The following page is a model of printing of the data recorded by a Datalogger and dumped on a disk through
the Carel Download modules – DLOGSER000. From October 1997 the portable module DLOGPC0000 will be
available. Both modules are managed by Windows™.
In fact each line of the table corresponds to a recording, of which the date, the hour, the temperature measured
by the probes, the state of the digital inputs and of the relay outputs, the information on the Power ON,
on the time change and the alarms are reported.
Furthermore, the data that are included within particular ranges ("filters") selected by the user via software are
pointed out in italic boldface. Thus, it is possible to detect which temperatures have exceeded the high or low
temperature thresholds or which are the data stored by the Datalogger at a certain time interval.
In the model page here reported the following filters were selected:
• Selection 1: the data stored between 12:00 and 13:30 hours of the 18/02/1997 day have been sought
• Selection 2: for the probe 1 a high temperature threshold equal to -17.5°C has been selected, equal to the
relative threshold selected in the Datalogger (and so in the Alarm column the corresponding alarm symbol
appears).
• Selection 3: for the probe 2 a low temperature threshold equal to -19.0°C, different from the relevant to
the threshold selected in the Datalogger (as a consequence, in the Alarm column no alarm symbol
appears).
• Selection 4: the probe 2 has been configured only at 9:00 hours of the 18/02/1997 day, and therefore there
are temperature recordings relevant to it only beginning from this hour. In the previous recordings the
character "-" is reported to indicate its absence.
For a two channel Datalogger model (such as the one presented in the example) the absence of the probes
3 and 4, of the digital inputs 3 and 4 and of the digital output 2 is similarly reported.
At the end of each page the serial number and model (2N=2 channels, 4N = 4 channels) of the Datalogger,
with which the data have been stored, the name of the operator in charge of the instrument, the signature and
date at and hour in which the print has been carried out are reported.
A space is also provided for the authentication of the document by the firm that is the holder of the
Datalogger, that may personalize the print by inserting its own name ("Supermarket "XYZ" in the example) at
the head of each page, near the logo and the writing "Datalogger Carel".
Finally it is worth noting that the print is optimized if the interval between two successive recordings is of 15
minutes. In this case to each page correspond the data being recorded throughout 24 hours.
Note: it is possible to print the temperature data graphic on a A4 format sheet. Please find an example of
graph print on page 42.
