3) Due to the discharge characteristics of the recommended battery, a battery replacement should be carried out
when a node reported voltage reaches 2.7V;
4) Our product will use all the possible capacity in a battery down to a stop (minimum) voltage, which has been
specified in the Features table. When this occurs, our WiSen protocol will send you a warning then it will enter a
deep sleep mode until a new battery is installed;
5) If the data from nodes are shown unexpected results or are not being sent back to the Wisen gateway, then please
carry out investigation using the following two stage procedure:
A. Remote Inspection of historical data, to identify the following:
a) Whether the heart-beat message has been sent back successfully at each time interval;
b) Whether the battery voltage is too low, if yes, please change the battery unit;
c) Whether the signal strength has become significantly weaker than it was previously. If yes, please
check the antenna has been screwed on firmly.
B. On-site Inspection: If all the above are good, please arrange an on-site inspection to check:
a) Whether the Tilt Node has visible external damage;
b) Check the box lid to see if it is firmly tightened;
c) Whether the antenna is bent or damaged and that the node is not blocked by new construction, e.g.,
hoardings;
d) When it is possible, check that the signal strength is normal by using a spectrum analyser;
e) Open the lid, to see whether the battery is firmly attached to its holder;
f) Use a multi-meter to measure the battery voltage. If it is below the stop (minimum) voltage, replace
the battery.
Notices :
i. Case One: If any change has been made from the list above, please inspect the data from the remote server;
ii. Case Two: If all the actions from the list above have not cured the problem, please contact Wisen. We will be
happy to help.
