WIRES (Fig. 9)
DISCONNECTING THE INJECTORS
The yellow wires of LCS A1 V05 are connected to
the contacts of a normally closed relay. During gas
operation, (Fig. 9A) the contacts of the relay open,
thus preventing the injectors from operating; when
the engine is fed with petrol, these contacts remain
closed.
Set the LCS A1 V05 Computer at the parameter
'OVERLAP TIME' preferable retard timing (in
seconds) of the contacts open in order to have a
suitable fuel overlapping during change from petrol
to gas. The maximum applicable current as a
continuous load is 6.5 A.
If an electronic emulator is used to disconnect the
injectors (Fig. 9B) and it is necessary to set a fuel
overlapping time, connect one end of the yello
wires of LCS A1 V05 to ground and the other to
the special connector on the electronic emulator.
NOTE: during gas operation, in case of eventual
malfunctioning
of
system, LCS A1 V05 will change automatically on
petrol.
7. LCS A1 V05 OPERATION
The programmable functions of LCS A1 V05 can
be set only by the Programmer Tester V05 or by a
personal computer with Interface Kit V05 and
dedicated software.
Also when the LCS A1 V05 is not fed (ex. batter
disconnected),
the
stored.

7.1 DATA DISPLAY
By the Programmer Tester V05 (or personal
computer with Interface Kit V05 installed) following
data are displayed:
• ACT: indicates (in number of steps) the actual
position
of
Actuator
• DEF: indicates (in number of steps) the acquired
default position (standard value) of the Linear
Electromechanical Actuator
• RPM: indicates (in rpm) the actual number of
revolutions of the engine
• TPS: indicates (in volt) the position of the throttle
position sensor
• TPS LEARNING RANGE: indicate if you are in
an idling condition, cruise condition or maximum
open throttle condition
• LAMBDA
SENSOR
indicate if you are in a poor or rich mixture
condition
With LCS A1 V05 Computer new or resetted the
'DEF' position of the Linear Electromechanical
Actuator is 100 steps .
The minimum TPS position and the default
position of the Linear Electromechanical Actuator
are acquired at every ignition of the system; the
last acquired default is used as starting position.
