Generator gauges
P1........ Ampmeter
Indicates the outgoing current in the first
phase (L1).
P4........ Voltmeter
Indicates the voltage between L2 and L3.
Qc1002™ Module
The Qc1002™ module is located inside the control
panel. This control module will carry out all
necessary tasks to control and protect a generator,
regardless of the use of the generator.
This means that the Qc1002™ module can be used for
several applications.
2.4.2 Outlet sockets (S)
2.4.2.1 Outlet sockets for QAX 12 1-phase
units
The outlet sockets application provides the following
outlet sockets and circuit breakers:
X1 .......1-phase outlet socket (230 V AC)
Provides phases L, neutral and earthing.
X2 .......1-phase outlet socket (230 V AC)
Provides phases L, neutral and earthing.
X3 .......1-phase outlet socket (230 V Y)
Provides phase L, neutral and earthing.
Q1 .......Main circuit breaker and minimum
voltage relay
Interrupts the power supply to X1 when a
short-circuit occurs at the load side or the
overcurrent protection (50 A) is activated or
when the shunt trip is energized. It must be
reset manually after eliminating the
problem.
Q2 .......Circuit breaker for X2
Interrupts the power supply to X2 when a
short-circuit occurs at the load side, or when
the overcurrent protection (32 A) is
activated. When activated, Q2 interrupts
phase L and the neutral towards X2. It can be
activated again after eliminating the
problem.
Q3 .......Circuit breaker for X3
Interrupts the power supply to X3 when a
short-circuit occurs at the load side, or when
the earth leak detector (30 mA), or when the
overcurrent protection (16 A) is activated.
When activated, Q3 interrupts phase L and
the neutral towards X3. It can be activated
again after eliminating the problem.
