AKO 5757H412 CO2 Gas Transmitter
Description
- 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.
-
- 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.
- PPM: The display shows the current gas concentration in ppm (parts per million).
- ×10: The value displayed should be multiplied by 10.
- Gas alarm on mute
- PRG: Unit in programming mode.
-
- 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 once (< 1 second) will show the type of gas detected, the date and time in sequential order.
-
- 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.
- Pressing for 3 seconds accesses the configuration of alarm and pre-alarm levels.
Start-up 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:MAS
- Enter the serial number (S/N) and validation code / IMEI that appear on the tag and press “Search”.
- 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:”http://help.ako.com/manuales/akonet-cloud”
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.
Operation
Without alarms
The display shows the current gas concentration in ppm. 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. There are two alarm levels depending on the concentration of gas detected: Pre-Alarm and Alarm. These have a factory setting of 1000 and 1400 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.There are two possible methods for modifying the transmitter’s configuration:
- Through the device’s programming menu (refer to the user manual available at www.ako.com).
- At www.akonet.cloud, by accessing the device parameters menu.
