For a LoRaWAN product
•
In the default LoRAWAN Class A operating mode, (see Radio settings chapter), if at the end of the 5 minutes
pairing phase, no network has been reached, then the product goes into standby and will restart a 5-minute
pairing phase 24 hours later. So, if the product is placed in an area not yet covered by a network, the product
will join it when connectivity is possible. There is no need to intervene on the product for it to join the
network.
•
In the LoRa/LoRAWAN Repeater Compatibility operating mode, (see chapter Radio parameters), if at the end
of the 5 minutes of the pairing phase, no network has been reached, then the product emits a
WHITE
light
signal and enters its nominal operating mode. Even if no network has been reached, it is assumed with this
mode that an ATIM LoRa/LoRAWAN repeater located nearby will be able to repeat the Local frames emitted
by the product in LoRAWAN frames on the network that the repeater has reached.
Sending a test frame
When the product is in its operating mode
(and only in this mode)
, it is possible to send a test frame (which
avoids waiting for the next measurement frame) including a measurement sample.
To do this, simply move the magnet against the QRCODE label, which turns the LED
GREEN
and wait for it to go out
before removing the magnet. The successful sending of the test frame will be indicated by a
CYAN
light signal.
Just before sending, a leak detection is performed, and a value of this measurement is integrated in the frame. This
ensures that the cable or the electrodes are correctly installed. The test frames are identical to the alert frames. See
their structure in the "Alert frames" section.
In the case of a cable without the "Distance measurement" option (yellow and black cable). The measured value should
be close to zero.
Deep sleep
When transporting or storing the ACW-WL, it is best to place it in its deep sleep mode to limit unnecessary power
consumption.
From any operating mode
(except fault mode)
, move a magnet against the QRCODE on the case for 6 seconds.
During these six seconds, the product's LED will flash the color corresponding to the operating mode and then
the end of the sequence will be indicated by a
WHITE
fade acknowledging that the product has been put to sleep.
The magnet can then be removed.
Radio module activity
Any radio frame transmission is normally indicated by three short flashes of
GREEN
color of the LED. This function is
disabled by default on all products with a front panel LED, such as the ACW-THAQ and ACW-WL.
Threshold exceeded
When thresholds have been configured using the configurator and the measurement values exceed these thresholds,
the product's LED emits a periodic
ORANGE
flash to notify this. This function is disabled by default on all products with
a front panel LED, such as the ACW-THAQ and ACW-WL.
