Type S controls for manoeuvering trolling valve
Single lever controls with a single function are suita-
ble for controlling a trolling valve*, if fitted. One of
these is the type S control.
*The trolling valve is an accessory for the Twin Disc reverse
gears MG507(A)-1.
VP dual controls
1. Lever for reverse gear manoeuvers (black handle)
Position N – Neutral
From N to F – reverse gear engaged for forward movement
From N to R – reverse gear engaged for reverse movement
2. Lever for controlling engine speed (rpm) (red handle)
Dual lever control
These controls have separate levers for acceleration
and shifting. A mechanical lock means you can shift
only when the acceleration lever is in the idling posi-
tion. The controls have a neutral position switch to
prevent starting with the reverse gear engaged. Both
control levers have separately adjustable friction
brakes.
NB dual controls
1. Lever for reverse gear manoeuvers (black handle)
Position N – Neutral
From N to F – reverse gear engaged for forward movement
From N to R – reverse gear engaged for reverse movement
2. Lever for controlling engine speed (rpm) (red handle)
One brake can be adjusted by turning this handle in order to
counteract the governor power
Electronic controls (TAMD72P)
The Volvo Penta electronic, single-lever control com-
bines the functions of a throttle and reverse gear op-
eration in one control lever unit. When starting, for
example, the shift function can be easily disengaged
so that only the engine speed (rpm)* is affected by
the lever.
The neutral position switch built in to the control unit
only allows the engine to be started with the reverse
gear disengaged.
A double single-lever unit is available for use with
twin engine installations.
*Note! The engine speed is limited to max. 2000 rpm in this
position.
Calibration
Before the engine is started for the first time the con-
trol must be calibrated according to the instructions
on the next page.
NOTE! If the calibration is not carried out the en-
gine cannot be started. (Diagnostic Trouble Code
(DTC) 1.6 will be flashed – “Control calibration not
done”).
