3. System Description
A. Electronic Control Box 59KD
The ECB is a full-authority microprocessor-based control-unit. This means that when an APU is started all further control of the APU is fully automatic and provided by the ECB. The subsystems listed below work with the ECB to operate all necessary APU sequence, protective and control logics:
The ECB together with the Data Memory Module (DMM) retains the APU data. At the beginning of the APU start, the ECB makes a copy of the recent APU life data, stored in the DMM. This data will be updated, during the APU operation and transferred back to the DMM when the APU is shutdown.

4. Power Supply
The battery bus 301PP supplies 28VDC to the ECB 59KD through the circuit breaker ECB SPLY 1KD and the relay APU MAIN 4KD. The 28VDC supply for the APU MAIN relay is through the circuit breaker APU CTL 2KD. The ECB continuously monitors its internal voltages and starts an APU shutdown if a voltage failure occurs. This prevents unsafe operation of the APU

(1) Fuel Control Logic
The Fuel Control Logic is divided into two sub-logics:
The Fuel Control Logic is divided into two sub-logics:
- Timed acceleration logic
and - On-speed governor loop.
(a) Timed Acceleration Logic
The timed acceleration logic accelerates the APU from zero speed (0% rpm) to governed speed (95% rpm) within controlled EGT limits.
The timed acceleration logic provides 'required-to-run' fuel to the APU, in relation to a given schedule (ramp), by computing the FCU Torque Motor current. The ECB does the computation and makes the correction every 20 mS.

(b) On-speed Governor Loop
During governed APU speed the on-speed governor loop controls the fuel flow to the APU. This keeps a constant APU speed (99.1% rpm or 100% rpm). The fuel flow is limited by programmed min. and max. fuel schedules.

(2) IGV Control Logic
The ECB measures the IGV position set-point in relation to the APU operation mode. This set-point is dependent on three factors:
The ECB measures the IGV position set-point in relation to the APU operation mode. This set-point is dependent on three factors:
- APU operating mode (i.e. MES, ECS etc.)
- APU inlet temperature (T2),
- Inlet pressure (P2)
(a) ECS Mode
The ECS mode operates when the APU BLEED pushbutton switch is pushed and the air conditioning packs are in operation. Then the Zone Controller 8HK sends the ECS demand through the ARINC 429 bus to the ECB (Ref. AMM D/O 21-63-00-00). This sets the Inlet Guide Vanes (IGV) position in proportion to the ECS demand signal. The ECS min position corresponding to zero % demand depends on T1 and T2.

This sets the Inlet Guide Vanes (IGV) position in proportion to the ECS demand signal. The ECS min position corresponding to zero % demand depends on T1 and T2.
(b) MES Mode
The MES mode operates when the APU BLEED pushbutton switch is pushed and a main engine start is initiated (Ref. AMM D/O 73-25-00-00). Then the FADEC sends a signal to the ECB. This sets the IGV position in a fixed position of 92 degrees.
When the engine starter valve closes, the FADEC removes the MES signal to the ECB and the ECB switches back to the normal operation mode.

When the engine starter valve closes, the FADEC removes the MES signal to the ECB and the ECB switches back to the normal operation mode.
(3) SCV Control Logic
The SCV control logics prevents load compressor surge for all modes of APU operation, ambient conditions (T2/P2) and A/C airflow requirements.
The ECB gets feedback from the SCV LVDT,computes the commanded position and corrects the current position every 5 mS.

The ECB gets feedback from the SCV LVDT,computes the commanded position and corrects the current position every 5 mS.
(4) Normal Shutdown Logic
(a) Commanded Shutdown
A normal APU shutdown is initiated when the operator pushes the APU MASTER SW from the ON to the OFF position. The ECB closes the IGVs to the min. position (15 degrees). The LCV closes and the SCV opens and the cool-down cycle of the APU starts.
A normal APU shutdown is initiated when the operator pushes the APU MASTER SW from the ON to the OFF position. The ECB closes the IGVs to the min. position (15 degrees). The LCV closes and the SCV opens and the cool-down cycle of the APU starts.
(b) Cool-down cycle
The function of the cool-down timer is to delay the APU shutdown and to allow the APU to run for 60 seconds at a low stabilized temperature at 100% speed (N).
The cool-down cycle starts immediately when the ECB receives the CLOSED signal of the LCV. The AVAIL signal remains active, the generator remains loaded if selected.
If the LCV was not in the OPEN position during the entire APU operation the cool-down timer is set to zero (0) seconds. The APU enters the shutdown state immediately when commanded to shutdown.
If APU Bleed is set to OFF more than 60 seconds before the APU MATER SW is set to OFF the APU is shutdown immediately.
If the APU MASTER SW is pushed before completion of the cool-down cycle the APU will shutdown only after the cooldown cycle is complete.

If the APU MASTER SW is pushed before completion of the cool-down cycle the APU will shutdown only after the cooldown cycle is complete.
(c) Overspeed Test
After the end of the cool-down cycle, the ECB sends an overspeed test signal to the overspeed shutdown circuit. This causes the overspeed shutdown logic to start an APU shutdown by closing the fuel solenoid in the FCU. In this mode no protective shutdown is recorded by the ECB.
After overspeed protection circuit is checked, the ECB attempts to modulate the fuel flow to keep the speed at 100 % rpm. If the ECB would be able to keep speed at 100 % rpm, it indicates that the fuel solenoid sticks in the open position.

(d) APU Rolldown
During APU rolldown the IGVs are set to the position corresponding to Bleed OFF (15 / 22 / 30 degrees) until APU speed has dropped down to 80 % rpm. Then the IGVs are set to 15 deg. An APU re-start is possible at any time if the speed is more than 7 % rpm.
When the speed has decreased to 7 % rpm the ECB commands the inlet door to close. Seconds after the speed is below 7 % rpm the ECB removes power from itself.
The APU can be restarted at any time during the rolldown when the APU MASTER SW is set to ON and the START P/B is pushed. But the APU accelerates only when the APU speed has fallen below 7% speed.

- Timed acceleration logic
and - On-speed governor loop.
(a) Timed Acceleration Logic
The timed acceleration logic accelerates the APU from zero speed (0% rpm) to governed speed (95% rpm) within controlled EGT limits.
The timed acceleration logic provides 'required-to-run' fuel to the APU, in relation to a given schedule (ramp), by computing the FCU Torque Motor current. The ECB does the computation and makes the correction every 20 mS.

(b) On-speed Governor Loop
During governed APU speed the on-speed governor loop controls the fuel flow to the APU. This keeps a constant APU speed (99.1% rpm or 100% rpm). The fuel flow is limited by programmed min. and max. fuel schedules.

- APU operating mode (i.e. MES, ECS etc.)
- APU inlet temperature (T2),
- Inlet pressure (P2)
(a) ECS Mode
The ECS mode operates when the APU BLEED pushbutton switch is pushed and the air conditioning packs are in operation. Then the Air Conditioning System Controller (ACSC) sends the ECS demand through the ARINC 429 bus to the ECB (Ref. AMM D/O 21-63-00-00). This sets the Inlet Guide Vanes (IGV) position in proportion to the ECS demand signal. The ECS min position corresponding to zero % demand depends on T1 and T2.

(b) MES Mode

When the engine starter valve closes, the FADEC removes the MES signal to the ECB and the ECB switches back to the normal operation mode.

(8) Normal Shutdown Logic
(a) Commanded Shutdown
A normal APU shutdown is initiated when the operator pushes the APU MASTER SW from the ON to the OFF position. The ECB closes the IGVs to the min. position (15 degrees). The LCV closes and the SCV opens and the cool-down cycle of the APU starts.

(b) Cool-down cycle
The function of the cool-down timer is to delay the APU shutdown and to allow the APU to run for 60 seconds at a low stabilized temperature at 100% speed (N).
The cool-down cycle starts immediately when the ECB receives the CLOSED signal of the LCV. The AVAIL signal remains active, the generator remains loaded if selected.
If the LCV was not in the OPEN position during the entire APU operation the cool-down timer is set to zero (0) seconds. The APU enters the shutdown state immediately when commanded to shutdown.
If APU Bleed is set to OFF more than 60 seconds before the APU MATER SW is set to OFF the APU is shutdown immediately.
If the APU MASTER SW is pushed before completion of the cool-down cycle the APU will shutdown only after the cooldown cycle is complete.

(c) Overspeed Test
After the end of the cool-down cycle, the ECB sends an overspeed test signal to the overspeed shutdown circuit. This causes the overspeed shutdown logic to start an APU shutdown by closing the fuel solenoid in the FCU. In this mode no protective shutdown is recorded by the ECB.
After overspeed protection circuit is checked, the ECB attempts to modulate the fuel flow to keep the speed at 100 % rpm. If the ECB would be able to keep speed at 100 % rpm, it indicates that the fuel solenoid sticks in the open position.

(d) APU Rolldown
During APU rolldown the IGVs are set to the position corresponding to Bleed OFF (15 / 22 / 30 degrees) until APU speed has dropped down to 80 % rpm. Then the IGVs are set to 15 deg. An APU re-start is possible at any time if the speed is more than 7 % rpm.
When the speed has decreased to 7 % rpm the ECB commands the inlet door to close. Seconds after the speed is below 7 % rpm the ECB removes power from itself.
The APU can be restarted at any time during the rolldown when the APU MASTER SW is set to ON and the START P/B is pushed. But the APU accelerates only when the APU speed has fallen below 7% speed.

- APU operating mode (i.e. MES, ECS etc.)
- APU inlet temperature (T2),
- Inlet pressure (P2)
(a) ECS Mode
The ECS mode operates when the APU BLEED pushbutton switch is pushed and the air conditioning packs are in operation. Then the Air Conditioning System Controller (ACSC) sends the ECS demand through the ARINC 429 bus to the ECB (Ref. AMM D/O 21-63-00-00). This sets the Inlet Guide Vanes (IGV) position in proportion to the ECS demand signal. The ECS min position corresponding to zero % demand depends on T1 and T2.

(b) MES Mode
The MES mode operates when the APU BLEED pushbutton switch is pushed and a main engine start is initiated (Ref. AMM D/O 73-25-00-00). Then the FADEC sends a signal to the ECB. This sets the IGV position in a fixed position of 92 degrees.
When the engine starter valve closes, the FADEC removes the MES signal to the ECB and the ECB switches back to the normal operation mode.

This shutdown logic is programmed to detect only steady reverse flow (min. 6 seconds). Momentary reverse-flow conditions do not cause an APU shutdown. The reverse-shutdown logic is enabled only when the APU is on-speed. The logic uses the total pressure- (PT) and the differential pressure (DP) transducer signals to sense a reverse-flow.

(p) Clogged Oil Filter Shutdown
The ECB shts down the APU if:
The ECB shts down the APU if:
- a clogged oil-filter signal is triggered
and - the oil temperature is higher than 100 DEG.F (37.78 DEG.C)
and - the APU is on governed speed condition (> 95 % rpm).
(q) Main Power Interrupt Shutdown
On every APU shutdown (normal or protective), the ECB sets a flag that a regular shutdown sequence has occured. On the next power-up the ECB checks this flag. If it is not set, it indicates that the previous APU run was terminated by a power loss, and the ECB records a loss of DC power shutdown.
Power interrupts shorter than 50 msec will not cause a shutdown.

8. BITE Test
The BITE tests the three subsequent BITE modes:
The BITE tests the three subsequent BITE modes:
- The Power Up Test (PUT),
- The In Operation Test (IOT),
- The self test if started from the MCDU.
- GND Scanning
A. Power-Up Test (PUT)
The PUT starts if the subsequent signals are available:
The PUT starts if the subsequent signals are available:
- the power up initialization is complete and
- the APU speed is below 7 % or
- the start signal received for more than 60 seconds.
B. In Operation Test (IOT)
The IOT tests all LRUs which are necessary for the APU operation. The IOT starts after the PUT.
The IOT tests all LRUs which are necessary for the APU operation. The IOT starts after the PUT.
C. Self Test
The self test is similar to the power-up test. It is operational when:
The self test is similar to the power-up test. It is operational when:
- the test is manual started from the MCDU,
- the APU speed is less than 7%.
D. GND Scanning
The GND Scanning gives the possibility to show system failure. You get access to the GND Scanning through the MCDU on ground, wether the APU is running or not. When the APU runs and GND Scanning is activated, the failures are shown when they occure. These failures are not memorized.

E. Alternate Values for Failed Sensors (Ref. Table 1)
(1) The ECB 59KD programs alternate values for certain failed LRUs. These are identified in the PUT or during the APU IOT. The LRU failures and the alternate actions are listed in Table 1.
