a) On the display will appear - Figure 132:
‘‘REEL SPEED SYNCHRO GAIN: 95 %’’
The reel speed synchronization system is an
automatic system which, if switched on with
switch 43 (Section 2, Fig. 10) in the instru-
ment panel, creates a linear relationship of
the reel speed (in m/sec) w ith the ground
speed. The ‘‘gain factor’’ is the factor which
controls the amount of increase of reel speed
for a certain amount of increase of ground
speed.
The s maller the factor (%) is , the smaller the
increase of the reel speed will be versus the
same ground speed increase.
Refer to Figure 133:
a Reel circumference speed (m/sec)
b Ground speed (m/sec)
x Relationship of reel speed to ground
speed with a factor of 100 %
y Relationship of reel speed to ground
speed with a factor of 95 %
The ‘‘gain factor’’ can be selected between 0
and 1000:
0: The reel speed is constant and inde-
pendent of the ground speed
100: When the ground speed increases 1
m/sec, then the reel speed increases
1m/sec
1000: When the ground speed increases 1
m/sec, then the reel speed increases
10 m/sec
