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.).
-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.

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.

The display shows the type of gas detected.
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)

The display shows the current gas concentration in ppm (parts per million).
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.
