Functions
2. LCS A1 V05 FUNCTIONS
LCS A1 V05 is used with following Lpg or Cng
LANDI RENZO pressure regulator: SE 81, SE 81
SIC, TN1, TN1/B, TN1 SIC, TN1/B SIC.
The LCS A1 V05 Computer processes the signals
from the lambda sensor, ignition, throttle position
sensor TPS and holds in memory a lambda sensor
tension value corresponding to the stoichiometric
mixture that needs to be maintained for ever
operating condition of the engine.
The lambda sensor in the exhaust
manifold
indicates the mixture ratio and at every moment
sends a value of voltage to the LCS A1 V05
Computer which checks whether the mixture is
correct by comparing it with the value set in
memory; if there is a difference, the computer will
drive the Linear Electromechanical Actuator,
suitably changing the rate of flow of gas until the
mixture comes back into the lambda stoichiometric
value.
The main functions of the LAMBDA CONTROL
SYSTEM A1 V05 include:
•
control
of
carburation
during
gas
operation;
•
petrol starting with automatic switch over to
gas;
•
possibility of emergency gas starting by simple
operation on the switch;
•
electronic safety device that cuts off gas
solenoid valve supply in the event of the engine
accidentally stalling;
•
built-in relay to cut off petrol injection with
automatic change over to petrol in case of LCS A1
V05 damage;
•
‘Petrol-Start’
function:
the
Linear
Electromechanical Actuator closes the gas line
while running on petrol and when the engine is
stopped.
•
interface system (using a diagnostic
connector) with a diagnostic and programming
instrument Programmer - Tester V05 or Interface
Kit V05 with dedicated software and serial
interface for personal Computer.
Parts installation
3. INSTALLATION OF COMPUTER LCS A1 V05
(Fig. 3)
The Computer must be attached to the car chassis
inside the engine compartment according following
instructions:
•
remove the fuses located on the wiring before
installing the parts and replace
them
once
installation has been completed;
•
position
the
Computer
away
from
sources
of
heat (exhaust header, radiators, etc.), protected b
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.
4. INSTALLATION OF THE LINEAR ELECTRO-
MECHANICAL ACTUATOR (Fig. 4)
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 A1 V05
computer to the connector on the Actuator.
IMPORTANT: never position the
Linear
Electromechanical Actuator with the motor facing
down or in such a way that oil deposits can
penetrate inside the motor.

INSTALLATION
AND
OPERATION OF
SWITCH / GAUGE LCS A1 V05 (Fig. 5)
Install the Switch / Gauge LCS A1 V05 on the
dashboard according following possibilities:
•
insert the Switch / Gauge LCS A1 V05 in an
existing hole with suitable dimensions;
•
insert the Switch / Gauge LCS A1 V05 in the
dashboard after making a rectangular hole (about
25x38 mm) with the LANDI RENZO cutting device
for switches;
•
position the Switch / Gauge LCS A1 V05 in the
dashboard by using the external support provided.
