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 ﬁ tted 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 certiﬁ cate, 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 ﬁ x the whole with the two screws (dimensions: 4x10mm) that are contained in the kit.

N.B. It is necessary to remove the two upper ﬁ xing 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 ﬁ x the back part of the Datalogger with the three screws (m, n, o) and the relevant Orings to the wall itself.

• Afterwards, ﬁ x 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 ﬁ xing 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 ﬁ x the cables by the proper cable-tie.

Important:

1. Avoid mounting the instrument in rooms with the following characteristics:

- wide and fast ﬂ uctuations 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 mm

at least.

4. Do not get near the electronic components mounted on the cards with your ﬁ ngers 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 ﬁ rst 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:

digital inputs

probes

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 ﬁ eld (“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 conﬁ gurated 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 and 7 in the mode “MODIFY PARAMETERS”.

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 ﬁ nding 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 modiﬁ cation, 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.

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

notiﬁ cation 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 ﬁ eld 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 conﬁ gurated.

• 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:

05/11/1996 12:53

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 ﬁ xed 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 Modiﬁ cation 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).

Speciﬁ cations for the Download

It is possible to transfer the data concerning the temperatures to be ﬁ led (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

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 (“ﬁ lters”) 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 ﬁ lters 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 conﬁ gured 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 ﬁ rm 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 ﬁ nd an example of graph print on page 20.

APPENDIX

Periodical veriﬁ cation procedures

CAREL certiﬁ es, with a paper included in the packaging (“Calibration certiﬁ cate”), that the Datalogger was calibrated in the factory. Nonetheless, as established by standard EN 13486, the instrument must be periodically tested to ensure the reliability of the data recorded. Whatever the outcome of the veriﬁ cation, this one must be noted down and kept. CAREL reports an example of forms (see enclosures A, B and C). CAREL advises to follow the periodical veriﬁ cation procedures here enclosed which generally follows veriﬁ cation procedures established by the normative law relevant to the CAREL Datalogger. For more details, please refer to the laws in force in your Country.

Measurement instrument

Direct comparison by using a measuring apparatus, periodically tested with thermometer and multimeter checked and certiﬁ ed by SIT. Since the Datalogger is guaranteed with a precision of ±1.0°C, the error of the standard thermometer must be lower than ±0.2 °C, resolution 0.1.

Preliminary operations

• Make sure the Datalogger is not near devices that cause electromagnetic interferences.

• Make sure the probes, and the relevant cables, are not placed immediately near other cables of electronic

and electric devices.

• Clean the probe.

• Check the connections to the Datalogger, by making sure the Datalogger is carrying out the measurement

of the temperature.

Performance of the veriﬁ cation

• Veriﬁ cation should be carried out around the working temperature, keeping it constant as much as possible. It is absolutely

necessary to avoid excessive changes of the equilibrium of the system, once the veriﬁ cation stage has been started (e.g. open

the door, to allow the compressor to start, switch on the light, ....).

• Place the calibrated thermometer as near as possible to the probe to be veriﬁ ed, striving for an acceptable thermal coupling (e.g.

by constraining the two - probe and Datalogger - sensors , with thermoconductive materials such as copper).

• Note down periodically the temperature simultaneously read by the precision instrument and the Datalogger, noting

downnpossible modiﬁ cations of the state of the system (e.g. stopped compressor, open door etc., so as to point out time response, delay time, heat radiation, etc.).

Results of the veriﬁ cation

If the difference between the value measured by the Datalogger and that of reference is:

• Lower than or equal to ±0.8° C , the outcome is acceptable.

• Ranging from -1.0 °C to -0.8 °C and from 0.8 to -1.0 °C, the outcome is acceptable, but the instrument must be veriﬁ ed within 6

months.

• Lower than - 1.0 °C and higher than 1.0 °C: the outcome is negative. If the veriﬁ cation has a negative outcome, you can try to replace the Datalogger probe. If the Datalogger with a new probe proved again to be out of precision, the instrument has to be returned to CAREL for a new calibration.

Important

The enclosures A and B of the manual are the masters to be photocopied at each veriﬁ cation. The copies of the enclosures A and B must be ﬁ lled in and kept and represent the veriﬁ cation report of the Datalogger instrument. The enclosure °C is the life-cycle sheet. It collects the data of each veriﬁ cation report. These documents do not replace the calibration certiﬁ cate issued by CAREL. CAREL can carry out, on request, the periodical veriﬁ cation of the Datalogger for the customers. Please contact CAREL after sales service.

Veriﬁ cation of the internal clock

The Datalogger records temperature and time. It periodically veriﬁ es the temperature measurement and also the precision of the internal clock. The maximum error permitted in the time measurement is 0.1% (equivalent to 8h and 40’ per year). In order to test this, use a sample clock with an error lower than of 200 ppm. and note the seconds it indicates the instant that the Datalogger display shows a change of minute. Repeat this operation after at least an hour. The two second readings of the sample clock should not differ by more than one second. In this case the test is passed.

The error range during these operations could in fact be considered not greater than 3 seconds (1s of error in the initial second reading, 1s in the ﬁ nal one and a maximum of 1s of difference between the two sample clock readings) on a measured total time of 3600 seconds (1h). In percentage, 3/3600 is an error lower than the 0.1% required. If the sample clock is a chronometer, the test is easier.

For example, if the ﬁ rst reading is 26” and the second is 27” the test can be plotted as follows:

Serial number: Installation date: Place:

Date Test duration Seconds of tot. error Resultant precision Result Operator signature

01/01/98 1h 3 0.083 yes ................................

CAREL guarantees that the clock has been calibrated at ambient temperature with a maximum error of 50ppm = 0.005% (equivalent to 26’ per year).
