9.3.10 Dual voltage (2V)
1 phase - 3 phase
The generator can run in two different modes:
1 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage.
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage.
3 phase - 3 phase
The generator can run in two different modes:
3 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage. (IT = active)
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage. (ELR = active)
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 (1 phase - 3 phase: 175 A /
3phase - 3phase: 152A) 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 (100 A) is activated. It must be
reset manually after eliminating the
problem.
R12......Voltage adjustment
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 K11 and K12 (refer
to circuit diagram 9822 0996 11/01) or S10b and S10c
(refer to circuit diagram 9822 0996 12/00).
The selection between the two modes is done by
means of S10.
The dual voltage option is only
available on 50 Hz units with
Qc1002™ controller.
