Output Terminal Board; Triple Voltage With Switch (3V-Sw) - Atlas Copco Qas 58Jd Manuel D'instructions

OUTPUT TERMINAL BOARD

The output terminal board is situated below the control panel.
Q2 ... .. Circuit breaker
Interrupts phases L1 and L2 towards X2 when a short circuit
occurs at the load side or when the over current protection is
activated. It must be manually reset after eliminating the
problem.
Q3 ... .. Circuit breaker
Interrupts phases L1 and L2 towards X3 when a short circuit
occurs at the load side or when the over current protection is
activated. It must be manually reset after eliminating the
problem.
Q4 ... .. Circuit breaker
Interrupts phases L1 and L2 towards X4 when a short circuit
occurs at the load side or when the over current protection is
activated. It must be manually reset after eliminating the
problem.
Q5 ... .. Circuit breaker
Interrupts phases L1 and L2 towards X5 when a short circuit
occurs at the load side or when the over current protection is
activated. It must be manually reset after eliminating the
problem.
X1 ... .. Main power supply
Terminals L1, L2, L3, N ( = neutral) and PE ( = grounding),
hidden behind the control panel door and behind a
transparent door.
X2 ... .. Single phase outlet socket
Provides phases L1, L2 and N.
1310 3011 32
X3 ... .. Single phase outlet socket
Provides phases L1, L2 and N.
X4 ... .. Single phase outlet socket
Provides phases L1, L2 and N.
X5 ... .. Single phase outlet socket
Provides phases L1, N, and PE.
R11 ... .. Output voltage adjust potentiometer
Allows to adjust the output voltage, R11 is located on the
control and indicator panel.
S2 ... .. Emergency Stop Button
Push the button to stop the generator in case of an
emergency. When the button is pressed, it must be unlocked
by turning it counter clockwise, before the generator can be
started.

TRIPLE VOLTAGE WITH SWITCH (3V-SW)

The generator can run in three different modes:
1 phase
-
3 phase, lower voltage
-
3 phase higher 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 be means of the auxiliary voltage selection
relays K11 and K12 (refer to circuit diagram).
The selection between the three modes is done by means of S10.
S10 ... . Output voltage selector switch
Allows selection of a 3-phase high output voltage, a 3-phase
phase low output voltage or a 1-phase low output voltage.
Selector switch S10 is located on the alternator.
Changing the output voltage is only allowed after
shutting the unit down. After changing the output voltage
be means of the selection switch S10, adjust the output
voltage by means of the potentiometer R11 to the
required value.
1 phase
When using this selection, the generator provides a 120/240V-
output voltage.
Q1.1 ... .. Circuit breaker for low voltage
Interrupts the low voltage power supply towards X1when a
short circuit occurs at the load side or when the over current
protection is activated. It must be manually reset after
eliminating the problem.
