activated, Q3 interrupts the three phases towards
X3. It can be activated again after eliminating the
problem.
Q4 .... Circuit breaker for X4
Interrupts the power supply to X4 when a short-
circuit occurs at the load side, or when the
overcurrent protection is activated. When
activated, Q4 interrupts the three phases towards
X4. It can be activated again after eliminating the
problem.
Q5 .... Circuit breaker for X5
Interrupts the power supply to X5 when a short-
circuit occurs at the load side, or when the
overcurrent protection is activated. When
activated, Q5 interrupts the three phases towards
X5. It can be activated again after eliminating the
problem.
X1..... Terminal board
Provides a more easy connection of cables.
X2..... 1-phase outlet socket (120 V)
Provides phase L2, neutral and earthing.
X3..... 1-phase outlet socket (120 V)
Provides phase L1, neutral and earthing.
X4..... 2-phase outlet socket (120/240 V)
Provides phases L1, L2, neutral and earthing.
X5..... 2-phase outlet socket (120/240 V)
X7..... External Power connection. 120V power
used to provide power to the factory
standard coolant heater and the optional
battery charger.
Triple voltage (3V)
The generator can run in three different modes:
– 1 phase
When using this selection, the generator provides a 120/240
V output voltage.
– 3 phase, lower voltage
When using this selection, the generator provides a 208/240
V output voltage.
– 3 phase, higher voltage
When using this selection, the generator provides a 416/480
V output voltage.
Q1.1 . Circuit breaker for low voltage, high current
Interrupts the low voltage power supply towards
X1 when a short-circuit occurs at the load side or
when the overcurrent protection is activated. It
must be reset manually after eliminating the
problem.
Q1.2 . Circuit breaker for high voltage, low current
Interrupts the high voltage power supply towards
X1 when a short-circuit occurs at the load side or
when the overcurrent protection is activated. It
must be reset manually after eliminating the
problem.
R12... Output voltage adjust potentiometer
Allows to adjust the output voltage.
Depending on which mode the generator is running in,
circuit breaker Q1.1 or Q1.2 will be operational.
Circuit breakers Q1.1 and Q1.2 cannot be switched on at
the same time. This is prevented by means of the auxiliary
voltage selection relays S10b and S10c (refer to the circuit
diagram).
The selection between the three modes is done by means
of S10.
S10... Output voltage selection switch
Allows to select a 1 phase output voltage, a 3 phase
high output voltage or a 3 phase low output
voltage. Selector switch S10 is located on the
alternator.
Circuit breaker Q1.1 and Q1.2 does not
only interrupt the power supply towards
socket X1 but also towards X2, X3, X4
and X5.
Make sure to switch on circuit breakers
Q1.1 and Q1.2, Q2, Q3, Q4 and Q5 after
starting the generator when power
supply is done by means of X2, X3, X4
and X5.
Changing the output voltage is only allowed
after shutdown.
After changing the output voltage by means
of the selection switch S10, adjust the output
voltage by means of potentiometer R12 to
the required value.
