Introduction
CAREL presents the new Datalogger range compliant with European directives 89/108/EEC, 92/2/EEC, EC regulation 37/2005
and Italian decree laws no. 110 of 27/01/92 and no. 493 of 25/09/95, which require the recording and conservation of data
corresponding to the temperature of frozen foodstuffs for at least one year. As regards EC regulation 37/2005, the Datalogger
model fitted with standard Carel NTC probe, code DLOGNTC015, is compliant with standard EN 12830 on temperature recorders
for the transport, storage and distribution of chilled, frozen, deep-frozen/quick-frozen food and ice cream. Designation of the
instrument: EN 12830, S, A, 1. -35T30 °C.
The Datalogger of the Carel range is an electrical device offered in various models, that can monitor and record data read by two
or four temperature probes. In this manual we present the two-channel model.
Kit
Description of the kit content: 1 Datalogger, 1 manual, 1 calibration certificate, 1 small bag containing 5 screws, packing. The
probes are sold separately. The use of CAREL code DLOGNTC015 probes is suggested.
Mounting
The Datalogger can be both panel or wall mounted.
Panel mounting
• Make a hole in the panel with the following dimensions: 182x153mm.
• Unscrew the two frontal screws (see a, b) and take out the central door (c).
• Unscrew the two screws (d, e) that keep connected the lower and frontal cover of the Datalogger and separate the two parts.
• Make two holes in the back part (in the perforated part- f, g).
• Join the back part and the front, with the panel in between, and fix the whole with the two screws (dimensions: 4x10mm) that
are contained in the kit.
N.B. It is necessary to remove the two upper fixing teeth (h) of the frontal part before the panel insertion. Make the hole in the
back upper (l) or lower part (i) to allow the cable passage. The pitches of the established threads ranges from PG9 (diameter:
16mm) to PG21 (diameter: 29mm). In order to make easier the drilling operation, the use of a drill and a cutter is suggested.
Connect the cables to the terminal block. Screw again the screws (d, e). Then screw the door (c).
Wall mounting
• Unscrew the two frontal screws (see a, b) and remove the central door (c).
• Unscrew the two screws (d, e) that keep connected the lower and frontal cover of the Datalogger and separate the two parts.
• Once decided where to pass the cable duct or the cables (from above or from below) and then after making the proper holes
(in the part drilled in advance - i, l) for cablepresses and pipepresses, make three holes (m, n, o) both in the Datalogger and in
the wall itself.
• Insert the “wall” nugs, contained in the kit, into the holes made in the wall and then fix the back part of the Datalogger with the
three screws (m, n, o) and the relevant Orings to the wall itself.
• Afterwards, fix the cablepresses or pipepresses before mounting the frontal part of the Datalogger.
• Subsequently, mount the frontal part, being careful with the positioning of the upper teeth (h) and the proper fixing of the two
screws (d, e) (do not press excessively in order to avoid plastic deformation).
• Only after the connection of the cables to the terminal block, the door can be shut again.
Attention: After the wiring fix the cables by the proper cable-tie.

Important:
1. Avoid mounting the instrument in rooms with the following characteristics:
- wide and fast fluctuations of the ambient temperature;
- relative humidity exceeding 80%;
- exposure to direct water jets under pressure;
- remarkable magnetic and/or radio frequency interferences (e. g., of transmitting antennas).
2. Utilize lugs suited to the terminal block in use. Loosen each screw and insert into them the lugs, afterwards tighten the screws.
Finally, gently pull the cables to check their correct clamping.
3. Separate as much as possible the cables of the probe signals and of the digital inputs from the power and inductive load
cables in order to avoid possible electromagnetic noises. Absolutely do not introduce into the same cable ducts (included
those of the electric cables) power cables and probe cables. Avoid the probe cables being installed close to power devices
(contactors, magnetothermals, or other devices). Reduce as much as possible the course of the probe cables in order to
prevent the occurrence of spiral courses enclosing power devices. To extend the probe cables, utilize cables with a minimum
section of 0.5 mm2at least.
4. Do not get near the electronic components mounted on the cards with your fingers in order to avoid stray
currents (extremely harmful) from the operator to the components themselves.
Connection
Caution: an improper power supply connection can seriously damage the system.
Power ON
When switched on, the instrument displays an introductive mask reporting the version of the software installed. After a few
seconds, the instrument enters the normal functioning mode, in which the read temperature and date are shown. At the first
switching on, the operation parameters are those of default (see the table on page 15).
Once selected, the desired values of the parameters are stored and recalled at every successive Power ON.
If at the switching on the mask:

appears, it means that the instrument has undergone damages of the hardware type (see the ALARM section).
Programming
The instrument allows the display and storage of the temperature measured with, at most, two distinct probes (NTC). The stored
temperature is the instantaneous value detected at selectable time intervals (see mask 3). In addition to the two probe inputs, the
instrument is equipped with two clean digital outputs and one exchange-relay alarm digital output. It is possible to choose whether
to activate only one probe or both.
Each digital input is coupled with only one of the two probes. The keyboard consists of six buttons, four of which are provided with
back-lit LEDs.

Date, hour and alphanumeric field (“Room 1” in the example) are selectable by entering the mode “MODIFY PARAMETERS”.
In the presence of particular conditions (alarms, defrosting) the unit of measure of the temperature (°C ) is being replaced
with a special character indicating the type of alarm or the cell state. As regards the description of the special characters and the
management of the alarm conditions, see the description of the “ALARMS” mode.
By pressing the buttons it is possible to scroll the temperature data previously stored (i.e. the “historical”), followed by
the relevant possible alarm characters (in this mode the LED relevant to the buttons lights up).
If at the storage moment the instrument was configurated for two probes, two temperature values will be displayed (only one
value otherwise). Other special characters show special situations such as a power supply failure, special character the letter “P”
(Power ON) in a time selection one “T” (Time) is being displayed, whereas one “D” indicates a “cell defrosting” (see parameters 6

In the absence of data of the historical, the following mask appears:
It is possible to select a date from which to begin to scroll the historical, by selecting the “CLOCK” mode. If no button is pressed for
at least one minute, the Datalogger automatically displays the main mask.

A gentle pressure on the button causes the following mask display appearance:
The cursor is already positioned on the first digit. It is now possible to select a date for the search of the temperature values at a
certain moment, in the “historical”: each pressure of the button carries the cursor onto a different field of date and hour.
The buttons permit the variation of each singular digit. With a last pressure of the button, the search of the data
corresponding with the selected date. The search is successful if a datum is found with a date corresponding with to the selected
one or if there are two dates respectively preceding or following the selected one. In case of discontinuities in the date storage
(e.g.: after a solar/summer time selection), it is possible that one and the same date appears several times. In this case the search
start recognizes the less recent one. By pressing the button, all the other ones are being circularly displayed. In the absence
of the searched datum or if, after finding a datum there are no other data to be shown, the following mask appears:
The prolonged pressure (about 3s) of the button displays the mask:
for the rapid change of the summer time to the solar time and viceversa. When the summer time is selected and the solar time is
requested, 1 hour is added to the clock by pressing the button (+1 ). If erroneously the button (-1 ), is pressed,
nothing happens. The same is true, with the due differences, in the reverse passage from the solar time to the summer time.
The modification, if it occurred, is automatically being accepted by the instrument. If no button has been pressed, the instrument
returns to the main mask after about 1 minute.
Caution: if the LED coupled to the CLOCK button blinks, this means that the Clock chip is damaged and a backup “virtual” clock
has been activated, in order to go on with the recording. For further details see the “Accidental alarms” section.

ALARM Button
ALARM Mode
The instrument can manage two different types of alarms, that is those directly dependent on the temperature change and those
caused by accidental conditions such as prolonged blackouts or damages to the Datalogger itself. In both cases, the recognition of
the alarm condition is followed by the buzzer activation (if previously enabled), the switching of the alarm relay and the lighting of
the red LED coupled with the button . A pressure on the button silences the buzzer, releases the relay and displays the
informative masks regarding the activated alarms. By moving with the buttons all the present masks are being scrolled,
if they are more than one.
• Lack of alarms, normal functioning conditions
If the button is pressed under normal conditions, simultaneously appears the mask:
• Alarms depending on temperature variation
For these alarms the user has the opportunity to select a time delay between the occurrence of the alarm condition and its
notification by means of the procedure that has been previously described (buzzer activation, relay switching, red LED lighting).
The alarms that depend on the temperature variation are:
- Open door (#): if the alarm is being signalled, the door of a cell remains open for a time exceeding the selected one.
- Short-circuited probe error (Err+): the instrument signals if a probe is short-circuited. The signalling delay is of one minute not
selectable.
- Open probe error (Err-): the instrument signals if a probe is open. The signalling delay is of one minute not selectable.
High and low temperature limits (!): the instrument signals if the temperature of one of the probes is beyond the selected limits
of high or low temperature (after time delay).
The alarms of this type are signalled in the main mask by special characters, here indicated in brackets, that appear overlapping
the field reserved to the temperature (or to the unit of measure) relevant to the alarm probe. If for a same probe two error
conditions occur simultaneously, the symbol “*” appears. Some examples are further illustrated. The masks relating to these
alarms that appear when pressing the button are:
Alarm of high temperature measured by the probe 1 (the case of the alarm of low
temperature and of the probe 2 is similar).
The probe 1 is short-circuited.
The door 1 is open (analogous for the door 2).
The hour reported in these masks that of the alarm beginning. As long as the alarm condition is present, the LED coupled
with the button is blinking, whereas when the anomaly cases the LED switches off. To better explain the use of the
special characters, below is shown how the main mask appears in the cases of alarm that can take place with only one probe
configurated.

The last one occurs when the limit of high temperature, selected in the mode of “PARAMETER MODIFICATION”, is placed ,
e.g.., at 30 °C. Analogous is the case of the low temperature alarm.
• Other alarms
For these alarms, a delay selectable by the user is not provided. They are:
- Blackout: if the parameter “Maximum Time of Blackout” (parameter 13 in hours) is enabled, the duration of each power failure
is evaluated in hours. If it is greater than the selected Maximum Time, the instrument warns through an alarm according to the
previously indicated procedure. The mask indicating the presence of this alarm is:
- System error: when switching on, in the presence of damages to the Clock chip, a routine of reconstitution of the Flash pointer
is started and on the display the following message will appear:
If the reconstitution has a favourable outcome, only the selected values of the parameters are lost, and so the instrument will
start again with the default values. The user is warned of this by an alarm and the mask:

System failure:
FLASH EPROM

ENGLISH
After stopping the alarm, it will be possible to reset the desired values of the parameters.
If on the contrary the reconstitution fails, it means that the temperature data previously stored are, at least in part, cannot be
retrieved. In this case the alarm starts and the fixed mask below appears:
Even though the Datalogger keeps on sampling the temperatures, the management of the stored data is no more ensured, and
so it is advisable to contact CAREL.
Furthermore, there is the case in which the instrument shows some irregularities of the Clock during the normal operation.
In this case a “virtual clock” begins functioning and ensures, as far as possible, the data acquisition and storage. The user is
informed on this possibility by the blinking of the LED coupled with the “clock” button, in addition to the usual alarm procedure.
The mask revealing this alarm is:
In the presence of this mask, it is advisable to insert the date again (see “Enter button - Parameter Modification Mode”). If this
mask persists, contact CAREL for assistance.
Anyway, the virtual clock is activated.
The temperature storing
The temperature data are stored together with the date and hour and further information that appear with the stored temperature
As regards the encoding of this information, see table 2.
Note that a selection of the sampling time lower than 14 minutes (also for a time period) does not ensure any more the data
conservation for the period established by the law (one year).

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 utilizing 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 established, press simultaneously the and . Now a mask for the choice of the established type of
Download is displayed.
When pressing the button the transfer of the data recorded by the previous Download starts. When pressing the

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 20.
