C-5.2.2 Operation

When power is turned on, light 4 comes on. The display
2 remains off and the monitoring system runs a self-
test before displaying the digit corresponding to the
used attachment on display 2. At this time, the system
is activated.
During operation, the led-bar 3 lights up gradually
depending on the variation of stability.
Green LED's: during normal operation when the
percentage of overturning moment is
between 0 and 89, these LED's are ON.
The machine is stable.
Yellow LED's: they light up when the machine tends
to overturn and the percentage of
overturning moment with respect to the
threshold value is between 90 and 100.
The system enters the pre-alarm mode,
light 10 flashes and the buzzer sounds
with an intermittent sound.
