Remote Control Display Bar
There are several features found on the Volvo EVC
or MerCruiser DTS remote control display. See the
individual buttons on the display strip shown on
the previous page. They include trim assist, cruise
control and tow mode. A brief description is found
below. Note that the MerCruiser DTS remote
control uses similar features. For a complete guide
refer to the engine operator's manual.
Power Trim Assistant- Activate the PTA by pressing
the Trim Assist button on the remote control.
When you press the button again you deactivate
the PTA. It automatically adjusts the trim angle
to the engine speed. This feature permits trim
functions to be loaded to control the in and out
movement of the drive unit which control the boat
angle and ride conditions. It eliminates the need
to use the trim button on the side of the remote
control handle. When the throttle changes the trim
servos automatically "pair" themselves with the
control handle position; full speed or anywhere in
between they will seek the optimum trim angle for
that speed.
Note that the power trim assistant will not move the
stern drive if it is manually trimmed above 7 degrees.
Note to ensure the PTA function is "off" if the vessel
needs to be removed from the water. This eliminates
automatic trimming of the drive if any test runs are
performed with the rig land locked.
Cruise Control- Activate the cruise control
by pressing the button. This feature
controls the vessel speeds in increments
of 50 revolutions per minute
as + or - on the control display. Each
time the + button is pressed the engine
rpm's increases by 50 rpm's. Each time
the - button is pressed the engine rpm's
decreases by 50. You can hit the plus or
minus 5 times from where you have the
throttles set. Beyond that it is time to move
the controls and start again.
You might find yourself using this feature
in heavy seas where you can make
changes as wave height, current and wind
conditions change and you do not want to
manually use the control handle.
Tow Mode- Activate the tow mode by
pressing the button. This feature is
especially useful in water sports where
you can program the throttle to remain at a
specified rpm. Once programmed the tow
mode will take the engine to that preset
rpm which is best suited for the rider.
Triangle Symbol- The triangle icon lights
up if the EVC system has registered a
fault; refer to the Fault Code Information in
the engine owner's manual.
Mil Light- (indicator light) lights up if the
engine's emission system has registered
a fault. At engine start, with the ignition on
and the engine not running, the MIL will
light on the control. This is a system test.
The light will disappear when the engine
is running unless there are engine faults.
