Hydraulic Fan Page
The Hydraulic Fan page (Figure 134) shows the status
of the hydraulic cooling system.
The hydraulic oil fan varies in speed and direction to
control the air flow through the hydraulic oil cooler.
This page monitors the following items:
•
Hydraulic Oil Temperature bar graph
N
OTE
:
“Fail to 100%” is the point at which the fan runs full
speed.
•
The Purge Information box shows the frequency
and duration of the fan purge cycle. If necessary,
such as when the machine runs in a very dusty envi-
ronment, this value can be raised (adjustable
through the Menu button).
•
Fan Direction—Shows current the fan speed rela-
tive to the maximum fan speed. Speed increases
with engine temperature.
•
Hydraulic Oil Fan Valve Output—Shows the
amount of current to the valve.
