What is the meaning of the ELEC EMERGENCY Warning CAS message?
Minimum GPU voltage for battery charging is:
If not in electrical emergency, the batteries are constantly charged by any source (except the GPU).
If not in electrical emergency, the batteries are constantly charged by any source, and this includes the GPU.
The two lead-acid 24 VDC batteries that power the Phenom 300 are also used as a backup for the emergency loads for _____ maximum, in case of a dual generator failure.
During normal operation, BATT 1 and BATT 2 switches set to the ON position, Battery 1 will be connected to the CENTRAL and charged by the SG 1, while Battery 2 will be connected to the BUS EMERGENCY BUS and charged by the SG 2. Battery 2 also provides electrical power for engine starting.
During normal operation, BATT 1 and BATT 2 switches set to the ON position, Battery 1 will be connected to the EMERGENCY BUS and charged by the SG 1, while Battery 2 will be connected to the CENTRAL BUS and charged by the SG 2. Battery 2 also provides electrical power for engine starting.
The primary power distribution system is composed of three electrical electronic integrated devices or Power Distribution Units (PDUs) that provide power distribution, airplane electrical load protection and interface with other systems. The three PDUs are the Left Power Distribution Unit (LPDU), the Right Power Distribution Unit (RPDU), and the Emergency Power Distribution Unit (EPDU).
Each PDU, incorporates contactors, relays, CB’s, fuses and DC electrical buses.
What is the meaning of a battery voltage indication showing a yellow X?
Normal operation of the electrical system is automatic and the two starter generators operate as the primary power sources in a parallel bus configuration to supply their respective DC bus.
The two starter generators operate as the primary power sources in a split bus configuration to supply their respective DC bus.
If both power-generating sources fail in flight, the automatism will command batteries 1 and 2 to supply the _____ providing engine starting capability.
On ground, for flight preparation or maintenance, the electrical power can be derived from the GPU. If the external power is removed and the BATT 1 and BATT 2 switches are set to OFF, all system contactors will be open and only the HOT BATT BUSES will be energized since they are directly connected to their respective battery.
Except in the normal or ground power source mode, the automatism will disconnect the SHED BUSES to prevent an overload on the remaining sources (in flight).

The _____ will be automatically isolated if a failure occurs in any of them during normal operation.
Minimum Voltage for Engine Start is:
What is the meaning of a battery voltage indication showing a white value?
In certain conditions, batteries 1 and 2 are used to backup all buses except the SHED BUS. Battery 2 also supplies the CENTRAL BUS, during engine starting.
When connected to the CENTRAL BUS, the DC external power source may be used to provide power for engine starting, in parallel with Battery 2.
