3 F2000EX EASY CODDE 1 PAGE 1 / 4 GENERAL INTRODUCTION The F2000EX EASy uses DC power for control, operation and indication of the various systems installed in the airplane. The electrical power supply system consists of a 28 V DC on-board generation system designed to minimize electrical fluctuation and power interruption. It supplies, controls and distributes DC power to the on-board electrical equipment through three main buses (LH, ESS and RH buses). Most of the avionics equipment is master switched on these respective buses: LH AV MASTER, MINI LOAD MASTER and RH AV MASTER. The Median (MD) bus is used for liaison purpose. The system is powered by two engine-driven generators and two batteries. It can also be supplied by an Auxiliary Power Unit (APU) driven generator. On ground, it can be supplied by an external DC Ground Power Unit (GPU).

7 F2000EX EASY CODDE 1 PAGE 1 / 10 DESCRIPTION GENERATION MAIN BATTERIES On ground, two 24 V (36 Ah) Ni-Cad batteries provide the primary source of DC power to the entire distribution system prior to APU starting. The BAT 1 supplies electrical power for starting the APU. As soon as one generator is connected, batteries are reloading and flatten generator electrical spikes. They are also capable of an emergency in-flight source of power for a limited period if all engine-driven generators fail. In that case, battery autonomy would be around 78 min (including 5 troubleshooting minutes) with maximum load shedding. The batteries are located in the forward servicing compartment accessible through the forward servicing compartment door. The batteries are ventilated, on the ground, by a battery-powered blower and by aerodynamic air flow in flight. During ground operation, the battery blower is operational when the BAT 1 switch is on. NOTE Very low-charged batteries cannot be connected to the buses, as their contactors need at least 18 V DC to close. OTHER BATTERIES Three batteries supply the emergency lights. One HORIZ BAT battery supplies Secondary Flight Display (SFD) in case of loss of LH bus for approximately 2 h 40 min. One AUX BAT battery when installed, may supply dedicated equipment. Four MAU-DU BAT buffer batteries supply the LH DU, UP DU, MAU1 and MAU2 so as to prevent them from dimming when the APU starts due to voltage drop. One of these supplies the Centralized Maintenance Computer (CMC) during shutdown. Four NIC batteries supply the NIC/PROC module of each chanel of MAU. Except for the batteries of emergency lights and NIC/PROC module, all battery voltages are monitored and indicated in the TEST synoptic page. The batteries of emergency lights can be checked by a three-position OFF-ON-ARM EMERG LIGHTS switch located on the overhead panel.

8 F2000EX EASY PAGE 2 / 10 CODDE 1 DESCRIPTION ENGINE-DRIVEN GENERATORS Engine-driven rectifier alternators are driven by the accessory gear box of each engine. A shear shaft in the generator prevents damages to the accessory gearbox in case of generator seizure. A damper in the generator shaft prevents from vibrations. They are rated at 12 kw and regulated at 28.5 V DC by their associated Generator Control Unit (GCU). APU GENERATOR The Auxiliary Power Unit (APU) is equipped with a starter-generator. On ground, it is capable of power the entire DC electrical system, in addition to charging batteries. It is rated at 9 kw and regulated at 28.5 V DC by its associated GCU. ENGINE-DRIVEN GCU The two Generator Control Units (GCU) provide current and voltage control and protection for their associated generator: - Control: the GCU regulates the voltage at 28.5 V DC. It monitors the output current in order to comply with peak power protection (above 400 A). It also provides generator output control in order to balance the voltage between several generators, when connected in parallel. - Protection: the GCU automatically disconnects its associated generator after debounce when the electric load limit is reached or overvoltage. APU-DRIVEN GCU The APU Generator Control Units (GCU) provides current and voltage control and protection for its associated generator: - Control: the GCU regulates the voltage at 28.5 V DC and monitors the output current to 300 A, with a maximum of 350 A for one minute. It also provides generator output control in order to balance the voltage between several generators, when connected in parallel. - Protection: the GCU automatically disconnects the generator when the electric load limit is reached or overvoltage. It also controls APU start sequence.

9 F2000EX EASY CODDE 1 PAGE 3 / 10 DESCRIPTION GPU An approved 28 V DC Ground Power Unit (GPU) may be used for prolonged periods to power the DC system in order to facilitate maintenance and servicing. The GPU may also be used for APU starting (recommended power is 1,000 A). When the GPU is connected and operating, generators and batteries are automatically disconnected from buses. If the airplane is equipped by the option charging batteries by GPU then it is possible to connect batteries to the buses when GPU is connected. FIGURE GPU RECEPTACLE LOCATION

10 F2000EX EASY PAGE 4 / 10 CODDE 1 DESCRIPTION DISTRIBUTION GENERAL DC power distribution is separated into three independent buses, allowing redundantly powered systems to continue to safely operate if one bus fails. The distribution system consists of 5 distinct buses: - battery bus, - ESSential bus (A5, ESS), - MD bus (connects battery 2 to RH or ESS buses), - LH bus (A1, A2, A3, CABIN), - RH bus (B1, B2, B3, GALLEY). FIGURE ELECTRICAL SYSTEM DIAGRAM

11 F2000EX EASY CODDE 1 PAGE 5 / 10 DESCRIPTION The battery bus is powered as soon as the battery 1 is installed and plugged in. Regardless of battery switch position, the battery bus provides electrical power directly to: - the fueling panel, - the emergency slat control circuit, - the APU starter circuit, - the engine FIRE extinguishers secondary discharge, - the fuel shut-off valves, - LIGHT 1 and LIGHT 2, main access door, available if at least one of the five trip magnetic switches is selected to on. Most of the avionics equipment is connected to the main buses through master-switches located on the overhead panel: FIGURE OVERHEAD PANEL

When a generator supplies the bus, the range of the analog scale is colored in amber below 25 V and above 30 V. This range is different in case of other electric configuration (bus supplied by batteries only, APU starting, ). NOTE Electrical information is also available on the STAT synoptic.

29 F2000EX EASY CODDE 1 PAGE 1 / 4 SYSTEM PROTECTION INTRODUCTION Feeder cables are protected by current fuses located inside the two main electrical boxes. Circuit protection is provided by conventional trip-free circuit breakers located on the circuit breakers panel. The circuit breakers panel is divided into different sections. Each section, delimited by different colored frames, corresponds to airplane major systems. In case of failure of one engine-driven generator, certain items, not essential for the flight, are automatically load-shed. The auto load-shed system is disabled when the airplane is on the ground, allowing normal operation of all cabin facilities. The BUS TIED rotary switch normal flight position is vertical, isolating left side buses from right ones. In case of overvoltage or short-circuit on one side, the other side is not affected. The ESS and MD buses can be temporary tied, for ground operations with no engine-driven generator assistance for example. When ESS and MD buses are tied, the contactor provides protection between them in case of overload on one side. BATTERIES The batteries are protected against excessive load by a trip magnetic switch, which opens and disconnects the battery when the charging (reverse) current exceeds 330 A for more than 3 sec. The BAT magnetic switch trips off and BAT.. CAS message appears. NOTE Only two reset attempts permitted. Batteries are ventilated on ground and in flight to protect them (hydrogen accumulation, heating). On ground, the ventilation by an electrical blower is operational when the BAT 1 trip magnetic switch is up and the position of the EXT POWER pushbutton is off. In flight, ventilation is provided by the effect of dynamic air flowing through a venting duct and blowing on the batteries.

30 F2000EX EASY PAGE 2 / 4 CODDE 1 SYSTEM PROTECTION GENERATORS AND APU The engine-driven generators and the APU are each monitored by a GCU. Main protections are: - voltage control (at 28.5 V DC ) and protection, - electric load protection, - reverse current,... The magnetic switch may trip off the corresponding generator. GEN.. CAS message will appear. CIRCUIT BREAKERS FIGURE CIRCUIT BREAKERS PANEL
