Instruments - Volvo Penta TAMD60A Instruction Book

Before starting to run your new marine engine, become acquainted with the controls and instruments. Make a habit
of checking the instruments now and again while running - any abnormal readings will then be detected in time.

Instruments

The most important instruments for the engine are grouped
on a basic panel (A). There is a second panel (B) with,
among other things, an hour meter, warning lamps, war-
ning siren and pressure gauges for the reverse gear oil
pressure and the turbo-charging pressure.
There is also a third panel (C) where a rudder indicator and
fuel gauge are fitted. (Panels B and C are optional equip-
ment).
1. Key switch with 4 positions.
Position 0 – the key can be inserted and removed
Position 1 – is not used, turn key past this position
Position II – running position
Position S – pre-heater engaged. Does not apply to
TAMD60.
(See also fig. 19)
2. Control lamp - (does not apply to TAMD60). This lights
up when the air pre-heater is engaged (key turned to
position S). It remains alight while the air pre-heater is
engaged (approx. 120 sec). The pre-heater
disengages automatically.
3. Stop button - pushing it engages the stop solenoid
causing the engine to stop.
4. Revolution counter, engine speed - multiply the
figures on the scale by 100.

Instruments and controls
The location of the panels in relation to each other can be
varied, since they are built to a modular system.
A separate panel with less instruments is available for the
Flying Bridge (optional equipment). See fig. 8.
The instrument panels for TAMD60 engines are not fitted
with the control lamps 2 and 7 (Fig. 7), since these engines
do not have air pre-heating. Otherwise the equipment is the
same as for the 70-engines.

and C, optional equipment)
5. Voltmeter, charging of batteries and system voltage.
With a 24 volt system, the gauge needle (during
running) should be pointing to approx. 28 volts, but for
a 12-volt system it should be approx. 14 volts. Should
the voltage during running drop to 24 (or 12) volts, the
batteries are not being charged.
The meter is wired via the master switch and indicates 24
(or 12) volts with the engine switched off.
6. Instrument lighting - indirected lighting of all
instruments. Turn the button to vary lighting strength.
7. Control lamp - (does not apply to TAMD60) - lights
when air pre-heater has been engaged long enough
for the engine to be started. The lamp lights about 60
seconds after the key has been switched to position S
and remains alight for about 60 seconds, that is, until
the pre-heater disengages automatically.
