Guarantees UNINTERRUPTED OPERATION of the monitoring system (CONNECTION BEFORE THE CHASSIS GROUND
SWITCH). The option should be used when round-the-clock monitoring of the vehicle is required. The sensor as well
as the monitoring terminal must be supplied directly from the battery.
IMPORTANT NOTE:
This connection scheme may only be used for sensors with a carbon plastic body.
Figure 8. Connection before Chassis Ground Switch
NOTE:
The fuse FA must be installed as close as possible to the supply power connection point in order to
ensure protection of onboard network from short-circuits in the power supply of the monitoring system.
NOTE:
Points
А and
B must be connected respectively to power (+) and ground (
–
) terminals on the battery.
IMPORTANT NOTE:
This connection scheme MUST NOT be used on fuel tanks of petrol-engine vehicles!
IMPORTANT NOTE:
When using the scheme, make sure that there is no connection between the sensing
assembly’s
outer tube and the tank body or between the
sensing
assembly’s
outer tube and the native fuel
level sensor.
IMPORTANT NOTE:
Installation of the fuse FA2 is mandatory. If, during operation, with the chassis ground
switch in
’disconnected’
position, the outer tube of the sensing assembly comes into contact with the tank
body or the native fuel level sensor, FA2 will protect the wiring of your system from burning out.
Advantages:
✓
Simplicity
✓
Guarantees round-the-clock monitoring
Disadvantages:
✓
Poor reliability, unless protected 100% from contact between the
sensing
assembly’s
outer tube and the
tank body or the
sensing
assembly’s
outer tube and the native fuel level sensor.
✓
Cannot be used on fuel tanks of petrol-engine vehicles.
