REF. DESCRIPTION
A FUEL indicator light to CHECK fuel circuit valves and pressure alarm
B High cylinder head temperature alarm indicator light (CHT).
C
Dual - purpose indicator light; when permanently lit, i t means that the motor
oil temperature is correct. When flashing it means that the timer is running,
setting off the buzzer every 2 minutes, to be used to return to position or for
various uses, such as, for example, to provide a reminder of closed valves in
flight.
D High motor oil temperature alarm indicator light
MANUAL
Motor oil pressure alarm indicator light; at its maximum in flashing mode,
minimum in steady mode.
F
Button for several functions; it silences the buzzer, it turns on the timer, it
pr ogrammes alarm thresholds.
G 3-
level flap indicator, T/O - ½ - FULL with timer buzzer at 1 minute, also
for programming the fuel alarm thresholds.

1.5 Instrument assembly
Install SAFETY- FLY 700 P where it is most comfortable for the pilot; in the
pictu re it is installed on the bottom right hand area of the motor instrument
dashboard.

Example of the connection between the orange wire and the CHT cylinder head
temperature instrument,
solution A: replace the original female terminal with a new one, connecting the
orange wire to the pre - existing one

2. PROGRAMMING
SAFETY -FLY 700 P can be programmed in two phases and in two different ways;
motor and flap alarm programming mode and fuel pressure alarm programming
mode.
2.1 PROGRAMMING MOTOR AND FLAP ALARMS.
Programming must be carried out when the motor is cold, with motor and cylinder
head oil temperature indicators below 50°C. Temporarily detach the wire for the
motor oil pressure bulb, as shown in figure 5

PROGRAMMING.
To start programming the SAFETY -FLY 700 P instrument must be off and
disconnected from the power.

2.1 PROGRAMMING MO TOR AND FLAP ALARMS.
To start programming, press the red RESET button, and hold it down (for
approximately 4 seconds) to power the instrument, releasing the button when the
first red CHT indicator light (ref. B) turns on.
Programming will now begin in a cyclical semi-automatic mode, i.e. the pilot will
interact manually with the instruments for the movement phase.
Programming starts with calibrating the cylinder head temperature alarm indicator
light (CHT), followed by the motor oil temperature (OIL TEMP), Min and Max
motor oil pressure (OIL PRESS), and display of the FLAPS.
The start and end programming sequence is shown in the table below, with the
exception of fuel pressure calibration, which is carried out in a following step using a
different m ode , explained in chap. 2.2

17
During programming SAFETY-FLY 700 P generates an electric output signal
simulating the movement of the motor instrument indicators located on the
dashboard.
To store the required alarm point, press the red RESET button, and when the
indicator for the instrument is in the required position, press the key down until the
buzzer beeps 3 times, indicating that programming has been carried out correctly.
Then, release the button and continue programming the next value.
If the index relative to the instrument that requires programming moves beyond the
level requiring programming, it is possible to go back by pressing the red button a
few short times.
Continue programming all of the values, as shown in the table below.

At the end of programming, turn the instrument off and reconnect the previously
detached motor oil pressure bulb wire, as shown in figure 6.

If you need to re-program one or more alarms without changing the correct
thresholds, start the programming phase as described above, let the cycle run, and
only when it is necessary to re-program the new threshold, press the button
corresponding to the required value.

2.2 PROGRAMMING THE FUEL PRESSURE ALARM.
The fuel pressure alarm threshold must be programmed with the motor running.
When the pressure of the fuel system is considered regular, press the RED button for
approximately 7 seconds until the flashing red Fuel indicator light ref. A, and the
acoustic buzzer, come on. Next, release the button and determine the fixed 3- level
operation percentage; 7, 16, 25%.
To determine the alarm operation percentage, the 3 LED flaps (G) are used and
defined as follows: led - T/O = +/ - 7%, led - ½ = +/ - 16%, led - Full = +/ - 25%.
Eac h LED will remain lit for 5 seconds, and if in that time the red button (F) is
pressed, the corresponding percentage will be programmed.
The programmed alarm threshold, based on the voltage level that is read at the time
of calibration, and the alarm will be triggered when the voltage value drops below or
rises above the percentage value of the programmed voltage.
