5.1 SWITCH / GAUGE LCS A1 V05 OPERATION
EXPLANATION
(A) gas / petrol selector
•
with 2 position and indication of used fuel b
mean of 2 leds (B) and (C);
(B) green led
•
turned on:
indicates the car is regularl
running on gas;
•
rapid flashing:
indicates the stand by for the
automatic change over during the starting (that is
always on petrol);
•
slow flashing:
indicates the malfunctioning of
LCS A1 V05 during gas operation (see par. 5.3).
(C) yellow led
•
turned on:
indicates the car is running on
petrol.
(D) led series
•
indicates the level of gas (divided into fourths)
present in the tank: the red led indicates the car is
running on reserve.
(E) connector
•
connect
the
switch
to
the
wires
coming
from
the LCS A1 V05 Computer.
5.2 EMERGENCY STARTING ON GAS WITH
SWITCH / GAUGE LCS A1 V05
In case of malfunctioning during the petrol starting
(ex. petrol pump damage, etc.), it is possible to
start directly on gas following listed instruction:
•
Turn the ignition key until the board is turned
on;
•
Set
the
switch
(A)
to
the
petrol
position
and
return it to the gas position without starting;
•
Now the green led (B) turns on;
•
Start the vehicle (without turn off the board). In
this condition the vehicle begin running directl
with gas.

6. LCS A1 V05 ELECTRICAL CONNECTIONS
It is recommended to solder listed
wire
connections and insulate them properly.
6.1 RED-BLACK AND BLACK WIRES (lt. N Fig. 1
and 2) COMPUTER
LCS
A1
V05
POWER SUPPL
To deliver a continuous power to the system,
made following connections of LCS A1 V05 wiring:
- red-black wire:
connect to the battery positive
- black wire:
connect to the battery negative
In the case the vehicle has the battery in the
luggage compartment, connect the red-black wire
to the positive pole in the engine compartment and
the black wire to an original common earth of the
electric equipment of the vehicle (ex. earth of the
petrol computer or other devices such as ABS,
power steering, etc.)
6.2 GREY AND VIOLET WIRES (Fig. 6)
LAMBDA SENSOR CONNECTION
The connection of the lambda sensor to the LCS
A1 V05 wiring is generally made by connecting
both the
violet
than the
grey
wires
of the LCS A1
V05 Computer on the outlet signal of lambda
sensor.
In some model of vehicles it could be necessary to
connect only the
violet wire
of the LCS A1 V05
Computer, while the
grey
one will be properl
insulated.
The explanation are shown case per case in the
TECHNICAL SHEET of the Technical Assistance
Service
LANDI RENZO
.
In order to facilitate the identification of the lambda
signal wire, herebelow are listed the most common
type of lambda sensor:
•
one-wire lambda sensor:
individuate the wire
that from the lambda sensor reaches the petrol
computer (Fig. 6A);
•
two-wire lambda sensor:
use a tester to
individuate the lambda signal wire: on this wire the
voltage with respect to ground could
varies
between 0÷1V, 0,8÷1,6V or 0÷5V);
