If you place the JUMPER between pins 1 and 2, the mode
is defined as INJECTION WITH AUTOMATIC CHANGE-
OVER FROM PETROL TO GAS DURING
DECELERATION, see

If you place the JUMPER between pins 2 and 3 the mode
is defined as INJECTION WITH AUTOMATIC CHANGE-
OVER FROM PETROL TO GAS DURING
ACCELERATION, see

If you remove the JUMPER, the mode is defined as
CARBURETOR, see

Operation of DELTA Change-over Switch in INJECTIÓN mode
GAS position of change-over switch
The vehicle runs on CNG at all times.
If the vehicle's ignition switch is turned on, the GAS electrovalve is opened
for approximately 3 seconds. This change-over switch is fitted with a safety
device that closes the GAS electrovalve if the engine stops accidentally.
While the GAS electrovalve is open, the two-colour led is on with a GREEN
colour.

AUTOMATIC position of change-over switch (central position of switch)
The vehicle starts on PETROL and changes-over to GAS automatically either
during acceleration or deceleration when pre-established RPM are exceeded.
This change-over switch is programmed for automatic change-over at 2500
RPM during deceleration for 4-cylinder vehicles with distributor.
Regulating the automatic change-over system.
The indicator must be placed in SETTING mode (special operating mode) as
follows:
Place the indicator switch on the central position, then turn the vehicle's
ignition switch on and, within the next 10 (ten) seconds, repeat the following
sequence 3 (three) times:
Move change-over switch to PETROL position.
Move change-over switch to central position (AUTOMATIC).
Make sure the change-over switch is left on the central position. The indicator
will be on the SETTING mode and this will be indicated by the ¼ and full leds
that will be on. At this moment, always with the ignition switch on, start the
vehicle and keep accelerated at the desired RPM for automatic change-over.
Move the change-over switch to the GAS position and then to the central
position so that these revolutions are memorized. The change-over switch
will engage the ½ and ¾ leds for a moment indicating the revolutions are
succefully programmed.
At this moment, (with the change-over switch on central position) you may
test programmed RPM by accelerating the vehicle and seeing that the two-
colour led changes from RED to GREEN when the programmed RPM are
exceeded. Turn the ignition switch off, and from now on, it is ready to operate
normally.
