Vehicle’s battery supervisor.
It is possible to enable a battery voltage supervisor; in this case driver will be informed about voltage
drop via SMS message.
How it works?
Each time ignition is switched OFF, terminal starts to monitor a vehicle’s battery voltage. In case if
voltage level drops below predefined value and remains this condition more than 30 seconds, than
terminal sends SMS alert to predefined numbers. In case is there are short voltage drops, terminal will
ignore it.
To setup battery supervisor, do as follows;
1. Define phone numbers to receive SMS alert message by setting parameter P42 and/or P48.
2. Set voltage threshold to trigger low voltage alarm by setting parameter P60.
Note!!!
In case of voltage drop detection, terminal will send only one SMS alert to each defined number after
that battery supervisor becomes passive. Switch ignition ON and then OFF to activate it again.
