Operation Autonomy - Novus LogBox Wi-Fi Instruction Manual

4. OPERATION AUTONOMY

LogBox Wi-Fi is powered by an external power supply, with a 10 to 30 VDC input, or USB port. The device can optionally be powered by four
standard "AA" batteries (1.5 V each) which, in the event of a power failure in the power supply source, will keep it running for at least two years. In
this case, to reduce consumption, the Wi-Fi interface will be disabled. All other features, however, will remain in operation for at least one year.
When power from the power supply source is restored, the Wi-Fi interface will be activated, and the data logged in memory during the power
interruption will be published in the services that support backup.
While the device is operated by batteries, very high temperatures (above 30 °C) or too low (below 10 °C) will cause battery chemistry to react
outside typical operating characteristics, reducing battery life. Thus, when operating the device in these ranges, consider that the two-year
expectation can be reduced considerably.
While the device is operating on batteries, temperatures too high (above 30 °C) or too low (below 10 °C) will make the LogBox Wi-Fi circuit greatly
increase its consumption. Thus, when operating the device in these ranges, consider that the two-year expectation can be reduced considerably.
Some scenarios can also increase LogBox Wi-Fi consumption, considerably reducing battery life expectancy. Here are some examples of
situations that may decrease battery life:
Alarm: Alarm occurrences more than once a day and with a buzzer duration over 30 seconds.
•
Event Log: Events that occur with a frequency greater than once every hour.
•
When necessary, the batteries can be replaced with any model that has characteristics like alkaline batteries (1.5 V). However, replacement with
Energizer E91 units (identical to those accompanying the device) or Energizer L91 (which has a higher operating temperature range) is
recommended to ensure the expected battery life expectancy and specified working temperature. If you choose another battery model, it is
necessary to check its working temperature and life expectancy.
Never mix batteries of different models, or new batteries with used ones. Whenever you are replacing the batteries,
replace all of them at the same time.
Check battery polarity before inserting it into the device. Never use an inverted battery.
While the LogBox Wi-Fi is powered by batteries, and to reduce power consumption, the Wi-Fi interface will remain
disabled.
