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 activated.
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.).
-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.

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. These have a factory setting of 500
and 1000 PPM respectively. 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.

Always disconnect the power supply to do the wiring.
The wiring between the transmitter and the station must be installed in a NEVER
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
