listed. Table 7-2: also lists the typical pressure range in bars dur-
ing troll operation.
The approach taken for adjusting the Trolling Valve may be based
purely on Shaft RPM, where the
L1
preset is used and the Value
is increased or decreased based on the Shaft RPM only.
The most effective approach is to use a combination of the
L1
preset, Shaft RPM and the measurement of the current flowing to
the proportional solenoid or pressure applied to the clutch plate.
Regardless of which approach is used, always adjust the
L1
pre-
set to the appropriate Value prior to adjusting the Troll Minimum
L2
and Troll Maximum

7-15.2.1 Enabling Troll
Press and hold the Transfer Button for two seconds with
the Control Head lever in the Neutral detent
• The Control Head’s red LED should begin blinking rapidly,
indicating that troll is enabled.
