OPERATION
To operate the device, the user must install the
NXperience
or
LogChart-NFC
application.
To communicate with the
TagTemp-NFC-LCD
, place the smart
phone over the device or a NFC interface. The distance range for
communication is relatively short, something few inches, this being a
feature of the NFC technology.
If the product is left unused for a long time and is in loop mode, it is
recommended to stop the operation. To do this, simply press the
Stop button via the
NXperience
or
LogChart-NFC
configuration
software.
5.1
Factory Mode
TagTemp-NFC-LCD
is factory-delivered in active state, but with its
display off. The display can be turned on by pressing the button or by
receiving a configuration via NFC. When pressing the button, it must
be kept pressed until the led lights on and must be released
immediately. This procedure will also start the logging process.
After a battery change, the equipment will go back to the factory
mode but will retain the last applied configuration.
5.2
Memory Mode
The use of computer memory may be:
•
Memory full: the records stops when there is more space in
memory.
•
Circular buffer: when reaching the end of memory, continuous
recording, overwriting the oldest records.
5.3
Log Beginning and Ending
The start of records may be immediate or by pressing the button
.
The ending of the records can be one of the following (whichever
comes first): Out of memory (when configured this memory usage),
command via the
NXperience
or
LogChart-NFC
, configuration
software
, or pressing the button
(when configured this option).
If you pressed the
TagTemp-NFC-LCD
button to stop the recording
data, and after a while, you pressed again to resume, the recording
will continue with a period without data information in memory. This
operation will occupy memory device data, resulting in less
temperature records on the available memory.
In addition, you can set a
Start Delay
time, which is the time that
TagTemp-NFC-LCD
will wait before starting the logs after each start
command. This time goes from 0 to 120 minutes.
5.4
LED Indication
TagTemp-NFC-LCD
has a LED for indication of its operation
•
One flash every 10 seconds: active;
•
Two flashes every 10 seconds: logging;
•
Three flashes every 10 seconds: alarm occurred;
•
One flash every 5 seconds: waiting the
Start Delay
time to be
over;
•
A quick flash followed by a slow one: beginning or ending of
records.
If the LED is always off, the battery is dead.
Note
: The LED flashing light is intentionally weak and can be difficult
to be viewed in bright places.
Start Delay
The Start Delay is a start-up delay, set by the user, in which
TagTemp-NFC-LCD
will wait before starting the logs. During this
delay time, the LED flashes every 5 seconds.
5.5
Button
The
button on the front panel can be used to display the
minimum and maximum temperature values, reset the minimum and
maximum values (when this option is configured) and start and/or
stop the records, depending on the configuration chosen.
To start the start or stop the records, with the LCD display showing
the current temperature, you must press this button until the LED
lights up and release it before the LED is turn off.
To reset the minimum and maximum values with the LCD display
showing the minimum or maximum temperature, press the button
until the LED lights up and release it before it goes out. The values
will be reset at the next LCD display update. If the LED goes out
before the button is released, the command will not be validated.
5.6
Temperature Unit
The temperature unit may be choosing by the user between
Celsius
(standard) and
Fahrenheit
. Changing the temperature unit causes
the need to send a new configuration.
5.7
Minimum and Maximum Temperature
With each update of the current temperature on the LCD display, the
minimum and maximum temperature values are updated, even if the
TagTemp-NFC-LCD
is not logging. These values are stored in
memory and are kept even after the battery is changed.
The minimum and maximum temperature values are reset at each
new setting, or via the
button (when this option is configured).
5.8
Sensor Error Indication
In case of sensor error (sensor broken or shorted), "
Err
" will be
displayed on the LCD display. If the
TagTemp-NFC-LCD
is logging
when an error condition occurs, the value -99.9 will be recorded in
the configured temperature unit. While the sensor is in error alarms
will not be generated, nor will updates of the minimum and maximum
temperature values. Exiting the error condition, the
TagTemp-NFC-
LCD
will resume temperature display and logging as usual.
5.9
Alarms
It is common, in the transport of perishable goods or sensitive loads;
there is a predetermined temperature range in which the transported
load must to be maintained. With the
LogChart-NFC
or
NXperience
application, you can configure alarms for viewing at the time a
collection is performed.
During logging, if the temperature exceeds the alarm limits, i.e.
whenever the temperature falls in or out the alarm conditions, an
alarm event is set. For alarm logging purposes, the temperature is
measured every 30 s, along with the display update.
Can be configured the use of two alarm conditions:
•
Temperature above the desired limit;
•
Temperature below the desired limit.
This indication can be viewed in the application or on
NXperience
. In
the application, you can check all alarm occurrence records using the
“Events Screen”.
The occurrence of an alarm condition can also be viewed through the
corresponding icons on the LCD display, and via the LED flash
pattern. These signals remain active even if the temperature exits the
alarm condition or the logs are terminated.
Alarm events share the memory with the temperature logs. Thus, the
more alarm events, the less temperature logs can be recorded to the
available memory.
