Admiral Control Panel - Universal M3-20A Operator's Manual

ADMIRAL CONTROL PANEL
UNIVERSAL offers two optional panels. Refer to the
instruction page that applies to the panel you purchased.
ADMIRAL PANEL
This manually-operated control panel is equipped with a Key
Switch and RPM gauge with an ELAPSED TIME metcr
which measures the engine's running time in hours and in
1110 hours. The panel also includes a WATER TEMPERA·
TURE gauge which indicates water temperature in degrees
Fahrenheit, an OIL PRESSURE gauge which measures the
engine'5 oil pressure in pounds per square inCh, and a DC
control circuit VOLTAGE gauge which measures the sys-
tem'5 voltage. All gauges are illuminated when the key
switch is turned
on
and remain illuminated while the engine
is in operation.
The
panel also contains two rubber-booted
pushbuttons, one for PREHEAT and one for START.
When the engine is shut down with the Key Switch turned
off, the water temperature gauge will continue to register the
Ja~t
temperature rcading indicated hy the gauge bctllfC elec-
tncal power was turned off. The oil pressure gauge will fall
to zero when the Key Switch is turned oft·. The temperature
gauge will once again register the engine's true temperature
when electrical power is restored to the gauge.
A
se~aratc
alarm buzzer with harness is supplied with every
Admiral Panel. The installer is responsible for electrically
connecting the buzzer to the
four~pin
connection on the
engine's electrical harness. The installer is also responsible
~or
installing the buzzer in a location where it will be dry and
where it will be audible
10
the operator should it sound while
t~eengin.e
is running. The buzzer will sound when the igni-
hon key
IS
turned on and should silence when the engine has
started and the engine's oil pressure rises above 15 psi.
WATER TEMPERATURE GAUGE: THIS GAUGE IS
GRADUATED IN DEGREES fAHRENHEIT AND IS
ILLUMINATED WHILE THE KEY SWITCH IS
TURNED ON. THE ENGINE'S NORMAL OPERATING
TEMPERATURE IS 170°·190° f 177°·BBOC).
OtL PRESSURE GAUGE: THIS GAUGE IS GRADU-
ATED IN POUNDS PER SQUARE INCH (PSI) AND IS
ILLUMINATED WHILE THE KEY SWITCH IS
TURNED ON. THE ENGINE'S NORMAL OPERATING
OIL PRESSURE RANGES BETWEEN 30·60 PSI
RPM GAUGE: REGIS·
TERS REVOLUTIONS
PER MINUTE OF THE
ENGINE AND CAN BE
RECALIBRATEO FOR
ACCURACY FROM THE
REAR Of THE PANEL
HOURMETER:
REGISTERS ElAPSED
TIME, AND SHOULD BE
USED AS A GUIDE FOR
THE MAINTENANCE
SCHEDULE.
PREHEAT BUTTON: WHEN PRESSED. ENERGIZES THE
ALTERNATOR'S REGUlATOR, THE FUEL LIFT PUMP, THE
fUEL SOLENOID ON THE INJECTION PUMP, AND THE
ENGINE'S GLOW PLUGS, AND BYPASSES THE I
OIL PRESSURE AlARM SWITCH. IN ADDITION, I
BUDON ENERGIZES THE START BUDON.
START BUTTON: WHEN
STARTER'S SOLENOID I
THIS BUDDN WILL NOT OPERATE ELECTRICALLY
UNLESS THE PREHEAT BUDON IS PRESSED AND HELD
ATTHE SAME TIME.

AUTOMATIC ALARM SYSTIM
KEY SWITCH: PROVIDES
POWER ONLY TO THE
INSTRUMENT PANEL
CLUSTER.
INDICATES THE AMOUNT THE
BATTERY IS BEING CHARGED
SHOULD SHOW 13V TO 14V.
HIGH WATER TEMPERATURE ALARM: AN ALARM BUZZER HAS BEEN
SUPPLIED WITH THE INSTRUMENT PANEL If THE ENGINE'S FRESH
WATER COOLANT REACHES 210° f 19BOC), THIS SWITCH WILL CLOSE
SOUNDING THE AlARM WHICH WILL EMIT A
CONTINUOUS SIGNAL.
LOW OtL PRESSURE AlARM: A LOW OIL PRESSURE AlARM SWITCH
IS LOCATED OfF THE ENGINE'S OIL GALLERY THIS SWITCH MONITORS
THE ENGINE'S OIL PRESSURE. SHOULD THE ENGINEiS OIL PRESSURE
FALL TO 5·10 PSI, THE SWITCH WILL CLOSE SOUNDING THE ALARM.
IN THIS EVENT, THE AlARM WILL EMIT A PULSATING SIGNAL
