GENERATOR WORKING VOLTAGE
Generator sets QAC 1100 Sd are produced to operate in
only one voltage (220, 380 or 440 V), and it is not
possible the quick selection/change of the voltage although
the alternator is capable to provide anyone of the voltages
by making changes in the connections of its cables.
To change the working voltage it is necessary to consider
the maximum power and current that the generator will be
able to supply at the requested voltage, protective
components shall be substituted and controls adjustments
shall be changed.
1. Technical Delivery:
Atlas Copco's technician or representative will not
make the working voltage change of the generator set,
which will be at the original voltage, and in case the
original voltage has been changed by the customer,
this change made by the customer will be described
in the service order (OS), and the customer will be
warned about the risks arising from this change and
notified about the loss of warranty of the items involved
in this voltage change in case there is a failure resulting
from this action.
Only after having clarified the issue of voltage change,
the equipment technical delivery will be completed.
2. Voltage change request after the technical delivery.
Atlas Copco and its representatives will only perform
this work with the substitution of the components for
the requested voltage.
The equipment warranty does not cover damages resulting
from changes made without the knowledge of Atlas Copco,
and mainly due to a voltage change without changing the
necessary items and properly configuring the electronic
controller.
The costs of these changes will be the entire responsibility
of the final user.
The costs of voltage change at the act of the technical
delivery shall be borne by the customer, unless it is proven
a delivery mistake on the part of Atlas Copco.If a
disagreement between the customer order and the supply
is verified, Atlas Copco assumes all the costs, that will be
charged to the department responsible for that error.
After having changed the generator working voltage, the
following shall be verified:
1. The electric current required by the load will be met
by the generator at the selected voltage?
2. The generator protection and control are compatible
with the voltage and current?
Generator Voltage Change
In all voltage change the position of E1 and E2 shall be
observed in the Voltage Regulating Plate (AVR) according
to the table below.Voltage and Frequency values shall also
be adjusted in the AVR,
otherwise the Voltage Regulating
Circuit Board can burn the connection .
Circuit board AVR
E1 : Voltage feedback (Low voltage)
GRT7-TH4 R2 AM/220M = 160 - 300VAC (single-phase).
GRT7-TH4 R2 EM/220M = 180 - 240VAC (single-phase).
GRT7-TH4 R2 GM/110M = 85 - 140VAC (single-phase).
E2 : Voltage feedback (Low voltage)
GRT7-TH4 R2 AM/220M = 320 - 600VAC (single-phase).
GRT7-TH4 R2 EM/220M = 520 - 640VAC(single-phase).
GRT7-TH4 R2 GM/110M = 170 - 280VAC (single-phase).
NOTE: Verify signal origin at the alternator connection
Adjust and regulate voltage
and frequency values in the
trimpots
In voltage chance is
necessary to change
the E1 and E2
