1.2 HOW IT WORKS
ETC device works processing the pre-set delays for VML cursor, acquiring the temperature readings sent by
the probe, in order to reduce the levelling distances while adjusting the FLY time in high-speed phase,
both in up-travel and in down-travel.

XTERNAL CONDITION
Temperature Probe
In the power unit standard operating mode, signals directly control the main valve. So the system is allways
affected by the change of temperature and viscosity.
ETC device controls the signals to the VML electrovalve, (that produces the switch between high and low
speed) in order to minimize both FLY time and energy consumption, depending on external conditions.
