575400N-NE Gas Transmitter
Warning
**** -Transmitters / detectors should be installed in a place protected from
vibrations, water and corrosive gases, where the ambient temperature does not
exceed the value indicated in the technical data.
-The transmitters / detectors are not suitable for areas classified as potentially explosive.
-Transmitters/detectors supervise a point and not an area. If the gas leak does not reach the sensor, or the level of concentration in that point does not reach the foreseen values according to the type of gas no alarm will be acti-
vated. If perimeter supervision is required, several sensors should be
installed around that area.
-Avoid installing the device on metal walls or near devices that may produce radio emissions.
-This device must be installed in a location where a minimum distance of 20 cm to the human body can be guaranteed, in order to ensure compliance with standards on human exposure to electromagnetic fields.
-The AKO-575400NE device must NEVER be operating without having installed the external antenna. This device can be fitted with any antenna provided it has a gain of less than 9.2 dBi and there is a minimum distance of more than 20 cm between it and any person or animal. Any type of antenna used with this device must comply with the limits established for the radio interface in Member States and the following documents: Comission Decision 2010/267/EU of 6 May 2010,ECC Decision (09)03 of 30 october 2009 and CEPT Report
30 of 30 October 2009.
Working conditions:
– Avoid handling refrigerant gases near the sensor. If this is unavoidable,
use Set Hold or Maintenance mode. Do not paint the sensor or place it near
solvents or paints. Exposure to acetone vapours may generate false alarms.
-The sensor should be installed away from: -Smoke outlets located in confined spaces or from engines, generators or motorised machinery (fork-lift trucks, etc.).
V3 Gas transmitter with
NBIoT communication
Quick guide
-Particularly damp areas or areas with strong ventilation.
-The detector should usually be installed in an area where gas may concentrate, near places where gas leaks could start
-The gases currently used in industrial refrigeration, for which this transmitter has been designed, are heavier than air. They are therefore always concentrated in the lowest part of the refrigerated room or space. Please take this into consideration when choosing the installation site. It is advisable to leave a distance of around 50 cm free
Always disconnect the power supply to do the wiring.
The wiring between the transmitter and the station must NEVER be installed in
a conduit together with power, control or power supply cables.
Cables for wiring the relay contact should have an adequate section depending
on the unit to be connected.
Certain international standards maintain that the power supply of the alarm
should originate from a different circuit to that used by the refrigeration
and ventilation system. Please ensure that you comply with current local
regulations.
If connecting to a MODBUS network the double connection strips included must
be used (see box)
Description
Fixed: Gas pre-alarm activated.
Flashing: Gas alarm activated.
Fixed: Set Hold mode activated
Flashing: Maintenance mode activated
The display shows the type of gas detected.
Constant: NBIoT module in operation
Flashing: Malfunction in NBIoT module
Constant: Connected to the NBIoT network (Narrow band)
Switched off: NOT connected to the NBIoT network or expired license.
The display shows the current gas concentration in ppm (parts per million).
The value displayed should be multiplied by 10.
Gas alarm on mute
Unit in programming mode.
If the gas Pre-Alarm or Alarm sounds, pressing once will mute the alarm tone
(See parameter b03).
In the programming menu, it exits the parameter without saving changes,
returns to previous level or exits programming.
Pressing for 3 seconds activates or deactivates Set Hold mode.
Pressing for 6 seconds activates or deactivates maintenance mode.
In the programming menu it allows scrolling around the different levels, or
during the setting of a parameter, changing its value.
Forces data transfer to the cloud via NBIoT connectivity.
Pressing once (< 1 second) will show the type of gas detected, the date and
time in sequential order.
Pressing for 3 seconds displays the Pre-Alarm and Alarm levels that have been
configured.
In the programming menu it allows scrolling around the different levels, or
during the setting of a parameter, changing its value.
Pressing for 3 seconds accesses the configuration of alarm and pre-alarm
levels.
Pressing it for 6 seconds accesses the advanced programming menu.
In the programming menu, it accesses the level shown on the display or, during
the setting of a parameter, accepts the new value.
Operation
Without alarms
The display shows the current gas concentration in ppm.
Parameter b02 allows you to fix a value below which the display will always
show zero.
The transmitter regularly sends to the cloud (akonet.cloud) the gas
concentration data and other operation information at specific intervals based
on the akonet.cloud parameter “continual log interval”.
Any change in the configuration of the transmitter or its operation (mode
changes, errors, etc.) are sent to the cloud instantly.
Alarms
The transmitter emits an acoustic alarm, the alarm indicator flashes and
activates the relays when certain gas concentration levels are exceeded. If
the transmitter is connected to a station, the station will emit the acoustic
alarm. The relays will be activated in both devices.
There are two alarm levels depending on the concentration of gas detected:
Pre-Alarm and Alarm. Both are factory preset but can be modified by means of
parameters AL3 and AL6. These values comply with domestic and international
regulations. However, please ensure that these values comply with current
local regulations. In order to modify these values, parameter AL1 should be
configured to 1. Activations and deactivations of pre-alarms and alarms are
sent to the cloud instantly.
Default parameters
To set the device to factory default, switch off the power supply and switch
it on again, press the sequence N, Q and SET within 2 minutes.
The display shows the message (default parameters) with a choice of two
options:
0: Parameters are not modified
1: All parameters are reset to their default values.
Signing up to akonet.cloud
In order for the transmitter to be able to send operating data to
akonet.cloud, it must be registered. To do this, go to https://akonet.cloud
(requires registration), click on “Add new device” and continue with one of
these two methods:
A.-Enter the serial number (S/N) and validation code / IMEI that appear on the
tag and press “Search”.
B.-Capture the QR code that appears on the tag using the option
(requires having a camera on your PC, tablet or mobile phone).
These data are found on the tag on the right hand side of the transmitter.
More information can be found in the akonet.cloud user guide at:
https://enhelpakonet.ako.com/
To access akonet.cloud, enter this address in your browser (the use of Google
Chrome is recommended): https://akonet.cloud.
** Before activating the device, make sure that there is enough reception
at the installation location. Activated devices may not be returned.
Forcing transmission
When the steps of the configuration wizard and the registration process are
completed in akonet.cloud, you must force a first transmission to verify the
level of reception:
Press and hold the ESC and SET keys for 3 seconds.
After a moment, the display shows the quality of the NBIoT signal received
:
** The transmitter does not start transmitting data to
akonet.cloud until the first transmission is forced.
Simplified declaration of conformity

Parameters
The unit operating parameters are organised in different groups or families
according to their function. The Def. column indicates the default parameters
set in the factory. In order to access the programming menu, hold the SET key
for 6 seconds, or until ‘’ PRG
’’ appears on the display. To modify the Pre-Alarm and Alarm levels, press
SET for 3 seconds or until “ ” appears on the display (Only if AL1=1).
This allows you to scroll through the different levels, or when setting a
parameter, to change its value.
SET This accesses the level shown on the display or, when setting a
parameter, it accepts the new value.
ESC This exits the parameter without saving changes, returns to previous
level, or exits programming.
