Spreading with automatic operating mode (AUTO km/h + AUTO kg)
Mass flow control with the M EMC function
Mass flow is measured separately on both disc sides. Thus deviations to the
specified application rate can be immediately corrected.
The M EMC function requires the following machine data for mass flow control:
PTO speed
Spreading disc type
PTO speed between 450 and 650rpm is possible.
The desired speed should remain constant during spreading (+/- 10
rpm)
. Thus high control quality can be ensured.
The empty run measurement is
only
possible if the actual PTO speed devi-
ates by
max. +/- 10 rpm
from the input in the
PTO
menu. Outside of this
range, idle measurement is not possible.
Preconditions for spreading:
The
AUTO km/h + AUTO kg
operating mode is active (refer to
).
