CHECK.TRACK.TRACE.
There are a few reasons that can abort an ongoing charge cycle:
 A defect battery: it takes too long to charge or another defect;
 Battery temperature is out of bounds: the temperature needs to be between ~0°C and ~40°C to
charge normally. If the temperature is below 0°C, the Gateway automatically reduces the battery
charge current to prevent damage to the battery and it takes longer to complete a charge cycle. If the
internal temperature is below -25°C or above 40°C a charge cycle is interrupted for as long as the
internal temperature is out of these bounds;
 Too much current consumption by other components. To protect the power supply, the charging is
suspended. E.g. if the product is powered through USB, it adheres to the requirements of the USB
standard, which limits the peak current an appliance may use.
Most of these suspend reasons have a temporary nature, however, if errors persist, please contact Ambient
Support. The power status LED will indicate a ‘suspended battery charging’ with a RED led.
!! Below 0°C and above 40°C the battery in the Gateway will charge with a very small charging current to
prevent damage to the battery
In some cases, in particular when the battery is deeply discharged, the Gateway may make a hissing noise.
This is normal and does not indicate a defect.
Typically, a battery charge cycle is completed within 4-8 hours.
6.3 System::Power (0:6)
The System::Power (0:6) driver reports information about the power status. It generates periodical reports
indicating the internal temperature of the product, time it took to charge the battery, how long it has
operated on the battery and so on. When the product operates on mains power, a report is generated once
every 15 minutes, otherwise every 5 minutes an update is provided.
If the mains power is lost, the device immediately generates an alert.
6.4 Configuring the use of the backup battery
Since the Gateway uses the USB port for both communication to a PC and powering of the device, the
Gateway is configured by default to turn off the network once mains power fails.
!! By default, the Gateway GW3030 v2.0 will turn off its networking functionality is not mains powered. This
behavior can be configured. Changing the setting is in particular useful when using RS232 as communication
port option
This behavior can be configured with the Network::Gateway driver to enable or disable the network when the
battery is the only available power source.
