BAT 1(2) pb
(ELEC Panel) - Auto - OFF - FAULT Light |
Auto:
The battery charge limiter automatically closes/opens the corresponding battery line contactor. The batteries are connected to the DC BAT BUS in the following cases: - APU starting until N < 95%. (limited to 3 min when the emergency generator is running) - Battery voltage < 26.5 V (battery charge). - Loss of AC BUS 1 & 2 when < 100 kt (EMER GEN not supplying). Battery 1 supplies AC STAT INV BUS and above 50kt the AC ESS BUS. Battery 2 supplies DC ESS BUS. OFF: The battery charge limiter is not operating, the battery line contactor is open. FAULT Light: The charging current for the corresponding battery is outside limits. In this case the battery contactor opens. |

IDG 1(2) pb (guarded)
(ELEC Panel) - FAULT Light |
Switch spring loaded out.
Do not hold > 3 sec. Do not disconnect when engine not windmilling. FAULT Light: - IDG oil outlet overheats (above 185°C), or - IDG oil pressure is low (inhibited at low engine speed: N2 below 14 %) LT extinguishes when the IDG is disconnected. |

GEN 1(2) pb
(ELEC Panel) - ON - OFF - FAULT Light |
ON:
Generator line contactor closes if electrical parameters are normal. OFF: Generator line contactors open. The fault circuit is reset. FAULT Light: - The generator control unit (GCU) trips it. - Line Contactor open with the GEN pb selected ON |
|
|
APU GEN pb
(ELEC Panel) - ON - OFF - FAULT Light |
ON:
Line contactor closes if parameters are normal and the EXT PWR line contactor is open. OFF: Line contactor opens. The fault circuit is reset. FAULT LT: - The generator control unit (GCU) trips it. - Opening of the line contactor (except if the APU GEN pb is selected OFF). The light is inhibited when APU speed is too low or if the APU GEN line contactor opens after EXT PWR or ENG GEN takes over. |
|
|
BUS TIE pb
(ELEC Panel) - AUTO - OFF |
AUTO:
The bus tie contactors (BTCs) open or close automatically. OFF: Both bus tie contactors open. |
|
|
AC ESS FEED pb
(ELEC Panel) - NORMAL - ALTN - FAULT Light |
NORMAL:
The AC ESS BUS is supplied from AC BUS 1. It is automatically supplied by AC BUS 2, when AC BUS 1 is lost. ALTN: Comes on when manually selected. The AC ESS BUS is supplied from AC BUS 2. FAULT LT: AC ESS BUS is not supplied. |
|
|
GALY & CAB pb
(ELEC Panel) - AUTO - OFF - FAULT Light |
AUTO:
Main galley, secondary galley and in-seat power supply are supplied. The main galley and in-seat power supply are shed automatically when: - In flight: only one generator is operating. - On the ground: only one engine generator is operating. (Except APU or EXT power.) OFF: The main galley, secondary galley and in-seat power supply are not supplied. FAULT LT: When the load on any generator is more than 100% of rated output. |
|
|
EXT PWR pb
(ELEC Panel) - AVAIL Light - ON Light |
AVAIL light comes on green if:
- External power is plugged in, and - External power parameters are normal. ON light: Pressed momentarily. Opens/Closes the external power line contactor. The ON light comes on blue when closed. |
|
|
COMMERCIAL pb
(ELEC Panel) - ON - OFF |
ON:
All aircraft commercial electrical loads are supplied: - Cabin and cargo lights - Water and toilet system - Drain mast ice protection - Galley - Passengers' entertainment - Semi-automatic cargo loading (if installed) OFF: Switches off all aircraft commercial electrical loads. |
|
|
MAN ON pb (guarded)
(EMER ELEC PWR panel) - AUTO - Pressed |
AUTO:
RAT deploys when AC BUS 1 & 2 is not electrically supplied and speed >100 kt. Pressed: Manual RAT extension. |
|
|
RAT EMER GEN
(EMER ELEC PWR panel) - FAULT Light |
FAULT LT:
This light comes on red if the emergency generator is not supplying power when AC BUS 1 & 2 are not powered. |
|
|
EMER GEN TEST pb (guarded)
(EMER ELEC PWR panel) - Pressed and held |
Pressed and held:
• If AC NORMAL BUSES are supplied: - The EMER GEN is driven hydraulically if the blue electric pump is running. The AC ESS BUS and the DC ESS BUS are connected to the emergency generator. (The DC ESS SHED and AC ESS SHED buses are not powered.) - ECAM displays the ELEC page automatically (only on the ground). • If only the batteries supply the aircraft: - The static inverter powers the AC ESS BUS. |
|
|
GEN 1 LINE
(EMER ELEC PWR panel) - OFF - SMOKE Light |
OFF:
GEN 1 line contactor opens. AC BUS 1 is supplied from GEN 2 through bus tie contactors. This is used for the avionics smoke condition to isolate GEN 1, but it continues to power one fuel pump in each wing tank. Smoke LT: Avionics smoke |
