Generator gauges
P3 .....Ammeter line L3
Indicates the outgoing current in the third phase (L3).
P4 .....Voltmeter
Indicates the voltage selected by means of voltage selector
switch S4.
P5 .....Frequency meter
Indicates the frequency of the supply voltage.
S4 .....Voltmeter selector switch
Allows to measure the voltage between each of the phases
and between each phase and the neutral. It also allows to
switch off the voltmeter.
Engine controls and lamps
ST .....Starter switch
The starter switch is a three-position switch which can be
operated with its specific key only.
Position O : the key can be inserted or withdrawn. When
withdrawn, the switch is locked and the voltage supply from
the battery is switched off.
Position I : the electrical system of the engine, except the
starting circuit, is energized. When the preheating system in
the engine air inlet has reached the required temperature, the
corresponding lamp (L3) goes out. The key may then be
turned to the next position.
Position : the starter motor of the engine is energized. As
soon as the engine fires, the key can be released. The switch
automatically returns to position I.
After approximately 20 seconds in position I without starting,
the control system will automatically shut down (battery
saving purpose) indicating a low oil pressure failure. In this
case, a reset of the control system by putting the switch in
position O is necessary.
F4......Fuse
The fuse activates when the current from the battery to the
engine control circuit exceeds its setting. The fuse can be
switched on and off by pushing the button.
L1......Alternator charging indicator
Goes out after starting, indicating that the alternator is char-
ging. A failing alternator however will not shut the engine
down.
L2......General failure indicator
Indicates that a shutdown appeared.
L3......Engine preheating system indicator
Lights up when the glow plugs in the engine, used to facilitate
starting, are warming up. Extinguishes after approximately 10
seconds. Bypassing of the preheattime is allowed e.g. when
starting a hot engine, but the preheat system remains active.
L4 .....Spare shutdown indicator
Can be used to wire an extra shutdown, e.g. for low fuel level
in case a switch is incorporated in the fuel tank.
Two DIP switches are foreseen on the back of the module to
choose the mode of the switch (Normal Open or Normal
Closed),
N.O. switch (factory setting)
N.C. switch
The connection of the extra shutdown has to be done on the
back of the module, terminal 3.
L5 .....Engine coolant temperature fault indicator
Lights up when the high engine coolant temperature was the
cause of shutdown.
L6 .....Engine oil pressure fault indicator
Lights up when the low engine oil pressure was the cause of
shutdown.
Circuit breakers
Q1.....Main circuit breaker, earth leak detector and minimum
voltage relay
Interrupts the power supply to X1, X2 and X3 when a short-circuit
occurs at the load side, or when the earth leak detector (30 mA)
or the overcurrent protection (20 A) is activated or when the DC
hold coil is not energised. It must be reset manually after
eliminating the problem and after each start.
Q2.....Circuit breaker for X2
Interrupts the power supply X2 when a short-circuit occurs at the
load side, or when the overcurrent protection (16 A) is activated.
When activated, Q2 interrupts the three phases towards X2. It
must be reset manually after eliminating the problem.
Q3.....Circuit breaker for X3
Interrupts the power supply X3 when a short-circuit occurs at the
load side, or when the overcurrent protection (16 A) is activated.
When activated, Q3 interrupts phase L3 and the neutral towards
X3. It must be reset manually after eliminating the problem.
