Signal Sequence Occurrence
LogTag wake-up
signal
Sequence of four
alternate ashes of
green-red LED’s
• displayed after conguration has been successfully applied to the LogTag
• when a LogTag is woken up from hibernation state
Not to be mixed up with...
LogTag start-up
signal
Sequence of sixteen
alternate ashes of
green-red LED’s
• displayed when the LogTag starts its recording cycle
Mark signal Sequence of ve
simultaneous ashes of
green and red LED’s
• displayed when pressing start/mark button while recording to indicate an inspection
mark in the software
• displayed directly after the start-up signal following a push button start where a
recording delay has been congured. In this instance the start-up signal is repeated
when the actual recording begins
Logging active, no
alert present
Single ash of green
LED every 4 seconds
(approx.)
• indicates LogTag is recording
• is is not displayed when pre-start is active and the main logging cycle has not
yet started. It is also not displayed when the green LED has been turned o in the
conguration screen
Logging nished,
no alert present
Single ash of green
LED every 8 seconds
(approx.)
• indicates LogTag has nished recording
• is is not displayed when the green LED has been turned o in the conguration
screen. Will also be displayed when unit has been woken up from hibernation
Alert condition
present
Single ash of red
LED every 4 seconds
• displayed when the LogTag has detected an alert condition and the Alert LED has
been activated
If an alert is present you cannot determine if the unit is still logging or has n-
ished its log cycle. If the Alert LED has not been activated during conguration,
in essence the visual indicators have been disabled, and the green LED will ash
every 4 or 8 seconds as above.
Communication e green LED will
ash occasionally
• during communication with the interface the green LED will ash occasionally; no
information is conveyed in this
Start button press red LED glows faintly • is is by design but conveys no information

For a full list of features please see the LogTag Analyzer User Guide,
which can be accessed through the Help Menu. You can also call up
on-line help information for all windows and dialogue buttons by
pressing the F1 key.
e LogTag Recorder itself can give you important status information
by ashing its indicators in dierent patterns. Both the red ‘Alert’ and
the green ‘OK’ LED’s convey information about conguration and trip
parameters, Alert status and give feedback when users interact with the
START/MARK button.
You will nd a summary of the indicator patterns with a description
about their meaning in table 2 on the right.
Once a LogTag has been congured, pressing the START/MARK
button has a dierent outcome depending on
what the logger is doing at the time the button
is pressed.
• If the logger is congured for a push button
start, pressing this button will activate the
main recording. ere is no need to be con-
cerned about any lost data if the user forgets
to press this button, as a pre-start recording
feature can be activated, logging data even
before the trip is started.
• Once the LogTag has been started, pressing
the button will insert an inspection mark in
the data recordings, which is displayed when
viewing the data in the software.
• If congured, Alert Conditions can be reset
when this button is pressed.
e software allows you to customise many
of the features to your individual require-
ments. Not only can you change some of the
more basic options like display language and
temperature units, but also adapt some of the
more advanced parameters for e-mail and FTP
functions, storage folder location, le name and
frequency for automatic software updates.

When you use the LogTag units, please take a
moment to consider the application and how
to best approach the monitoring task. Allow the units to be located in
a place with good air movement, make sure HAXO units are not lying
at so water and dust cannot gather around the sensor lter and pro-
vide adequate insulation around access holes for sensors with probes.
LogTag has achieved certication with a number of Authorities,
demonstrating the quality and suitability of the LogTag Recorders for
applications where accuracy and consistency is required. Such certica-
tions have - amongst others- been issued by such organisations as the
FCC, CE, C-TICK, TÜV and the WHO.
Compliance to the FDA requirements is available to users via a special
server utility, available on request, which can log events and be used to
digitally sign data les.
LogTag data loggers are rugged and need little maintenance, it does pay
however to observe some basic rules when handling the recorders to
maximise their use.
All LogTag data loggers have a replaceable battery. In some products,
however, these batteries are soldered to the electronics to avoid contact
issues that exist with other branded loggers; you will need some solder-
ing expertise and a battery replacement kit from your distributor. Please
also note that the products do contain a non-rechargeable Lithium Bat-
tery, which must be disposed of in accordance with local regulations.
To prolong the life of your data logger, you can hibernate it between
trips via LogTag Analyzer when it is not being used for extended peri-
ods. Please refer to the User Guide in the section about ‘Hibernation’

Please carefully observe the IP rating for your unit
and remember that none of the LogTag products
can be immersed into liquids.
Keep the three metal contacts at the back of the
logger clean and free from tape residue, dirt or
other contaminants, as these usually result in
communications problems. If required, clean
them with a soft pencil eraser, but don’t use abra-
sive materials as you may permanently damage
them.
If after studying the User Guide you still need
further information, please visit the Support sec-
tion of the LogTag Recorders website.
...for choosing LogTag Recorders, we are looking
forward to working with you!
