INSTALLATION OF COMPUTER LCS/2
(Fig. 3)
The Computer must be attached to the car chas-
sis inside the engine compartment according fol-
lowing instructions:
- remove the fuses located on the wiring before
installing the parts and replace them once instal-
lation has been completed;
- position the Computer away from sources of heat
(exhaust header, radiators, etc.), protected by
water and away from ignition high voltage wires;
- position the Computer with the connector side
facing down to prevent any water droplets from
penetrating inside the control unit through the
connectors.

INSTALLATION OF THE LINEAR
ELECTRO-MECHANICAL ACTUATOR
(Fig. 4)
4.1 LOW-SPEED ACTUATOR (ATT-MIN)
The reducer with linear electro-mechanical actua-
tor must be positioned parallel to the direction of
movement of the vehicle.
Fit the male jack (marked by the RED terminal from
computer LCS/2) in the connector on the actuator.
For more details, refer to the STEP MOTOR re-
Installation and adjustament manual Lambda Control System/2
ducer installation instructions inside the reducer
pack.
4.2 MEDIUM-HIGH SPEED ACTUATOR
(ATT-MAX)
The Linear Electromechanical Actuator must be
installed preferably at the mixer inlet (in order to
optimise the cut-off function) or, in alternative, along
the gas hose or on the regulator outlet.
Insert the male pin coming from the LCS/2 com-
puter to the connector on the Actuator.
IMPORTANT: never position the Linear Electrome-
chanical Actuator with the motor facing down or in
such a way that oil deposits can penetrate inside
the motor.
5.
INSTALLATION AND OPERATION OF
SWITCH / GAUGE LCS/2 (Fig. 5)
Install the Switch / Gauge LCS/2 on the dashboard
according following possibilities:
- insert the Switch / Gauge LCS/2 in an existing
hole with suitable dimensions;
- insert the Switch / Gauge LCS/2 in the dashboard
after making a rectangular hole (about 25x38 mm)
with the LANDI RENZO cutting device for
switches;
- position the Switch / Gauge LCS/2 in the dash-
board by using the external support provided.
5.1 SWITCH / GAUGE LCS/2 OPERATION
EXPLANATION
A) gas / petrol selector
with 2 position and indication of used fuel by
mean of 2 leds (B) and (C);
B) green led
turned on: indicates the car is regularly running
on gas;
rapid flashing: indicates the stand by for the au-
tomatic change over during the starting (that is
always on petrol);
slow flashing: indicates the malfunctioning of
LCS/2 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/2 Computer.
