3.24 Adjusting the air-flow
3.24.1
Hydraulic fan "Fenix"
The air volume is adjusted using the fan speed.
The fan speed can be adjusted in various ways, depending on the tractor on which it is mounted:
A
The fan is controlled using the tractor’s flow valve. A flow valve is available on most tractors
with a constant pressure hydraulic system. If the tractor has a priority hydaulic connector, be
sure to use this. Control of the hydraulic pressure from the tractor’s hydraulic system will then
be optimized for the hydraulic fan and on the tractor. Before installing an external valve ac-
cording to alternative (b) or (c), check whether a flow valve is optionally available for the trac-
tor’s hydraulic system.
Figure 3.49
B
If the tractor is equipped with a constant pressure hydraulic system but no flow valve, the fan
speed is instead controlled with a check valve installed on the pressure line between the tractor
and the sowing machine. The check valve can be ordered as already fitted or can be fitted on
models without this valve (part no. 420160).
C
If the tractor has a constant pressure system, the fan rpm can be adjusted using an additional
rpm regulator placed between the hydraulic hoses of the tractor and drill or on the fan holder.
The optional speed regulator can be ordered fitted or can be fitted later (part no. 420154).
Use the fan rpm as indicated in the table below. Check the fan rpm in the Control Station display.
The low rpm alarm on the Control Station should ideally be programmed to 300 rpm below the
set rpm while the high rpm alarm should be set 300 rpm above the set rpm. See ”
