INSTALLATION AND SETUP GUIDE
Fuel theft alarm.
With the help of fuel theft alarm it is possible to inform a driver about fuel level change in fuel tank
during parking time. In case if fuel level will be changed, driver will be informed about it via SMS
message. Fuel theft alarm has two channels, one of channels is related to standard fuel sensor input,
and second channel is related to analog input. Both channels can work separately or the same time.
How it works?
Each time when ignition is switched OFF, terminal waits till activation time is finished, than remembers
current level in the fuel tanks. In case if fuel level has been changed more than defined value,
monitoring terminal will send extra event to the server and warning SMS messages to predefined phone
numbers. Using specially designed input, fuel theft alarm
works even vehicle’s electronic control units
becomes sleep mode and there are no power on standard fuel sensor.
To setup fuel theft alarm, follow these steps
:
1.
Enable fuel theft alarm by changing value of parameter
P40
(for first fuel tank) and/or
P45
(for
second fuel tank). Please remember, this parameter also defines a fuel level drop threshold for alarm
triggering.
2.
Set alarm mode by setting parameter
P41
, this parameter is common for both fuel tanks alarms.
Available options:
a.
If
P41 = 0
–
alert will be send only to server, no SMS will be sent.
b.
If
P41 = 1
–
alert will be sent to the server and SMS alert will be sent to defined numbers.
c.
If
P41 = 2
–
alert will be sent to the server and SMS alert will be sent to defined numbers. Also
Digital Output (grey wire) will be activated for 20 seconds (for siren or light indication)
3.
Define phone numbers to receive SMS alert by setting parameters
P42
(for first phone number)
and
P48
(for second phone number).
4.
Define level change direction to trigger fuel theft alert by setting
P43
(for first fuel tank) and/or
P46
(for second fuel tank). Available options:
a.
If
P43/P46 = 0
–
alert will be triggered in case of level changes to both directions.
b.
If
P43/P46 = 1
–
alert will be triggered in case if measured fuel value will be increased.
c.
If
P43/P46 = 2
–
alert will be triggered in case if measured fuel value will be decreased.
5.
In case if you want to change fuel theft module activation time (default is 20 seconds), change
parameter
P44
to required value (time), this parameter is common for both fuel tank alarms.
Note!!!
In case of fuel theft detection, terminal will send only one SMS alert to each defined number, after
that fuel theft alarm becomes passive. Switch ignition ON and then OFF to activate fuel theft alarm
again.
