3. System Description
A. Forward Cargo Compartment
The forward cargo compartment has items installed which permit the loading of bulk cargo.
On the forward cargo compartment door there is a control panel from which you operate the CLS in the cargo compartment. One person is sufficient to operate the CLS.
A joystick on the control panel controls the movement of ULD to and from the five loading bays in the cargo compartment. The control panel sends electrical signals through the control box to the applicable power drive units (PDU). The PDU move the ULD in the necessary direction to their related bays. When a ULD is in the related bay, you secure it with a manually operated latch. If a power failure or malfunction occurs, it is possible to load/unload the ULD manually.
The components of the CLS are:

When a ULD is in the related bay, you safety it with a manually operated latch. If a power failure or malfunction occurs, it is possible to load/unload the ULD manually.
The components of the CLS are:
The forward cargo-compartment has items installed which permit the loading of the bulk cargo
The forward cargo-compartment has tie down points, attachment points and multiple attachment points. The tie down points are for the attachment of the straps and/or nets which hold large or small items of bulk cargo. It is always necessary to use the nets and straps to safety all large or small items of bulk cargo. The tie down points are also for the attachment of the divider nets.
The forward cargo compartment has one divider net (type A2) installed FR31. The divider nets divide the cargo compartment into sections.
Door nets type A and C are installed near the forward cargo-compartment door. The door nets prevent damage to the cargo compartment door and keep the door areas clear of any bulk cargo. The door nets have stanchions which give them strong contour. The door nets must always be installed after cargo is loaded/unloaded.
The multiple attachment points are for the attachment of the door nets to the cargo compartment floor. The attachment points are for the connection of the stanchions to the cargo compartment ceiling.

Two door sill latches are installed in the forward cargo compartment, on the door sill, at FR26 and FR27.
Each door sill latch has:
- A housing
- A manually operated YZ-latch
- An overridable Y-latch
- A guide-in roller
- A limit switch.
The functions of the door sill latches are:
- To prevent the accidental roll-out of a ULD
- To lock a ULD in position
- To hold the ULD vertical with the guide-in roller.
(a) Manually operated YZ-Latch
The manually operated YZ-latch locks the ULD in the door area in position. When the YZ-latch is lifted, a spring pushes on a pawl which locks the YZ-latch in position. When you push the release lever on the side of the door sill latch down, the pawl disengages and permits a spring to lower the YZ-latch manually until the pawl locks it in position. When the YZ-latch moves, it operates a limit switch.

When you push the release lever on the side of the door sill latch down, the pawl disengages and permits a spring to lower the YZ-latch manually until the pawl locks it in position. When the YZ-latch moves, it operates a limit switch.
(b) Limit Switch
The limit switch supplies an electrical two-way lock. It prevents the operation of the cargo compartment door when the YZ-latch is in the lowered position. The limit switch also electrically isolates the cargo loading system when the YZ-latch is in the lifted position.

(c) Overridable Y-LATCH
A ULD can move over the Y-latch, but only in the load direction. The ULD pushes the Y-latch down. A spring lifts the Y-latch again when the ULD is moved away. Thus the latch prevents the accidental roll-out of a ULD.
To unload a ULD you must lower the Y-latch. To lower the Y-latch electrically, you operate the SILL LATCH switch on the control panel. When you operate the SILL LATCH switch, the electric motor of the actuator starts to turn and lowers the Y-latch through an actuating mechanism.
If an electrical malfunction occurs, you can lower the Y-latch manually. To lower the Y-latch manually, operate the manual door-sill latch lever which is installed between the door sill latches

C. Components to Control the forward Semi-Automatic Cargo Loading System
(1) Control Panel
Control panel 2020VU1 for the forward semi-automatic cargo loading system is installed at the forward edge on the inner face of each cargo compartment door. On the control panel there is:
POWER ON/OFF switch 5MY is a toggle switch.
Four-position joystick 4MY goes back to the center/neutral position automatically. The joystick controls the operation of the PDU. The joystick is gated to permit the manual selection of one operation at a time. The four positions available are:
When the POWER ON/OFF switch is set to ON, power is supplied to the system when the YZ-latches of the door sill latches are lowered. This operates the limit switches (2004VU1, 2004VU2) for the forward system.
When you put the POWER ON/OFF switch to the ON position, the power contactor in the control box closes, and AC and DC power is supplied to the system. The control box has a monitor circuit which controls the power to POWER light 7MY. The POWER light comes on when the power supply is correct.
DOOR SILL LATCH switch 6MY is a toggle switch. An internal spring keeps it in the UP position. DOOR SILL LATCH switch 6MY operates the overrideable Y-latch of the door sill latch. To lower the overrideable Y-latch, put the DOOR SILL LATCH switch to the DOWN position and hold it there. This causes actuator 20MY for the forward system to operate and lower the overrideable Y-latch.
You can release DOOR SILL LATCH switch 6MY when the ULD is above the overrideable Y-latch. It then goes back to the UP position. The actuator is then in operation and compresses a spring in the mechanism. The spring makes the overrideable Y-latch move to the lifted position when the ULD is moved away.
Control panel 2020VU1 for the forward semi-automatic cargo loading system is installed at the forward edge on the inner face of each cargo compartment door. On the control panel there is:
- One POWER ON/OFF switch 5MY
- One joystick 4MY
- One DOOR SILL LATCH switch 6MY
- One POWER indicator light 7MY.
POWER ON/OFF switch 5MY is a toggle switch.
Four-position joystick 4MY goes back to the center/neutral position automatically. The joystick controls the operation of the PDU. The joystick is gated to permit the manual selection of one operation at a time. The four positions available are:
- IN - the lateral PDU operates in the load direction
- OUT - the lateral PDU operates in the unload direction
- FWD - the longitudinal PDU operate in the flight direction
- AFT - the longitudinal PDU operate against the flight direction.
When the POWER ON/OFF switch is set to ON, power is supplied to the system when the YZ-latches of the door sill latches are lowered. This operates the limit switches (2004VU1, 2004VU2) for the forward system.
When you put the POWER ON/OFF switch to the ON position, the power contactor in the control box closes, and AC and DC power is supplied to the system. The control box has a monitor circuit which controls the power to POWER light 7MY. The POWER light comes on when the power supply is correct.

This causes actuator 20MY for the forward system to operate and lower the overrideable Y-latch.
You can release DOOR SILL LATCH switch 6MY when the ULD is above the overrideable Y-latch. It then goes back to the UP position. The actuator is then in operation and compresses a spring in the mechanism. The spring makes the overrideable Y-latch move to the lifted position when the ULD is moved away.
(2) Control Box
Control box 1MY is installed on the right hand side behind the sidewall panels of the forward cargo compartment between FR28 and FR29.
The control box has two relays, which are, the power relay D2 and AC reverse relay D1. The control box also has an electronic circuit card, terminal junctions and two electrical connectors.
The power relay D2 operates to on when it gets the signal from the control panel. Thus the power relay D2 supplies the AC reverse relay D1 with 115/200 V AC. The 115/200 V AC then goes through connector B (pins number A, B and C) to the PDU. The power relay D2 also supplies 28 V DC to:
The PDU have a 3-pole relay which is operated by 28 V DC. The 28 V DC is (PDU operation signal) supplied from the control box to the 3-pole relay. The DC return is given through the related proximity switch when the XZ-single latch 32 is in the lowered position. This causes the 3-pole relay to send the 115/200 V AC to the PDU motor. Thus the power supply is stopped when you lift the XZ-single latch 32. The power supply is also stopped when the joystick is back in the center/neutral position.
The electronic circuit card has the logical functions which are necessary for the commands of the joystick. When the joystick is pushed to a position, the AC reverse relay D1 is set to the correct phase sequence. Thus the associated PDU (lateral or longitudinal) start. The electrical circuit card also keeps the last position of the reverse relay D1. The reverse relay D1 only changes to the opposite position when a different direction for the PDU is set.

Two door sill latches are installed in the aft cargo compartment, on the door sill, between FR53 and FR54 and at FR55.
Each door sill latch has:
- A housing
- A manually operated YZ-latch
- An overridable Y-latch
- A guide-in roller
- A limit switch.
The functions of the door sill latches are:
- To prevent the accidental roll-out of a ULD.
- To lock a ULD in position.
- To hold the ULD vertical with the guide-in roller.
(a) Manually operated YZ-Latch
The manually operated YZ-latch locks the ULD in position in the door area in position. When the YZ-latch is lifted, a spring pushes on a pawl which locks the YZ-latch in position. When you push the release lever on the side of the door sill latch down, the pawl disengages and permits a spring to lower the YZ-latch manually until the pawl locks it in position. When the YZ-latch moves, it operates a limit switch.

When you push the release lever on the side of the door sill latch down, the pawl disengages and permits a spring to lower the YZ-latch manually until the pawl locks it in position. When the YZ-latch moves, it operates a limit switch.
(b) Limit Switch
The limit switch supplies an electrical two-way lock. It prevents the operation of the cargo compartment door when the YZ-latch is in the lowered position. The limit switch also electrically isolates the cargo loading system when the YZ-latch is in the lifted position.
The limit switch supplies an electrical two-way lock. It prevents the operation of the cargo compartment door when the YZ-latch is in the lowered position. The limit switch also electrically isolates the cargo loading system when the YZ-latch is in the lifted position.
(c) Overridable Y-Latch
A ULD can move over the Y-latch, but only in the load direction. The ULD pushes the Y-latch down. A spring lifts the Y-latch again when the ULD is moved away. Thus the latch prevents the accidental roll-out of a ULD.
To unload a ULD you must lower the Y-latch. To lower the Y-latch electrically, you operate the SILL LATCH switch on the control panel. When you operate the SILL LATCH switch, the electric motor of the actuator starts to turn and lowers the Y-latch through an actuating mechanism.
If an electrical malfunction occurs, you can lower the Y-latch manually. To lower the Y-latch manually, operate the manual door-sill latch lever which is installed between the door sill latches

G. Components to Control the Aft Semi-Automatic Cargo Loading System
(1) Control Panel
Control panel 2020VU2 for the aft semi-automatic cargo loading system is installed at the forward edge on the inner face of each cargo compartment door. On the control panel there is:
POWER ON/OFF switch 5MY is a toggle switch.
Four-position joystick 4MY goes back to the center/neutral position automatically. The joystick controls the operation of the PDU. The joystick is gated to permit the manual selection of one operation at a time. The four positions available are:
When the POWER ON/OFF switch is set to ON, power is supplied to the system when the YZ-latches of the door sill latches are lowered. This operates the limit switches (2004VU3, 2004VU4) for the aft system.
When you put the POWER ON/OFF switch to the ON position, the power contactor in the control box closes, and AC and DC power is supplied to the system. The control box has a monitor circuit which controls the power to POWER light 7MY. The POWER light comes on when the power supply is correct.
DOOR SILL LATCH switch 6MY is a toggle switch. An internal spring keeps it in the UP position. DOOR SILL LATCH switch 6MY operates the overrideable Y-latch of the door sill latch. To lower the overrideable Y-latch, put the DOOR SILL LATCH switch to the DOWN position and hold it there. This causes actuator 120MY for the aft system to operate and lower the overrideable Y-latch.
You can release DOOR SILL LATCH switch 6MY when the ULD is above the overrideable Y-latch. It then goes back to the UP position. The actuator is then in operation and compresses a spring in the mechanism. The spring makes the overrideable Y-latch move to the lifted position when the ULD is moved away.
Control panel 2020VU2 for the aft semi-automatic cargo loading system is installed at the forward edge on the inner face of each cargo compartment door. On the control panel there is:
- One POWER ON/OFF switch 5MY
- One joystick 4MY
- One DOOR SILL LATCH switch 6MY
- One POWER indicator light 7MY.
POWER ON/OFF switch 5MY is a toggle switch.
Four-position joystick 4MY goes back to the center/neutral position automatically. The joystick controls the operation of the PDU. The joystick is gated to permit the manual selection of one operation at a time. The four positions available are:
- IN - the lateral PDU operates in the load direction
- OUT - the lateral PDU operates in the unload direction
- FWD - the longitudinal PDU operate in the flight direction
- AFT - the longitudinal PDU operate against the flight direction.
When the POWER ON/OFF switch is set to ON, power is supplied to the system when the YZ-latches of the door sill latches are lowered. This operates the limit switches (2004VU3, 2004VU4) for the aft system.
When you put the POWER ON/OFF switch to the ON position, the power contactor in the control box closes, and AC and DC power is supplied to the system. The control box has a monitor circuit which controls the power to POWER light 7MY. The POWER light comes on when the power supply is correct.
DOOR SILL LATCH switch 6MY is a toggle switch. An internal spring keeps it in the UP position. DOOR SILL LATCH switch 6MY operates the overrideable Y-latch of the door sill latch. To lower the overrideable Y-latch, put the DOOR SILL LATCH switch to the DOWN position and hold it there. This causes actuator 120MY for the aft system to operate and lower the overrideable Y-latch.
You can release DOOR SILL LATCH switch 6MY when the ULD is above the overrideable Y-latch. It then goes back to the UP position. The actuator is then in operation and compresses a spring in the mechanism. The spring makes the overrideable Y-latch move to the lifted position when the ULD is moved away.
(2) Control Box
Control box 101MY is installed on the right hand side behind the sidewall panels of the aft cargo compartment between FR51 and FR52.
The control box has three relays which the are AC power relay, the ON/OFF relay and the AC reverse relay. The control box also have an electronic circuit card, terminal junctions and two electrical connectors.
The power relay operates to on when it gets the signal from the control panel. Thus the power relay supplies the AC reverse relay with 115/200 V AC. The 115/200 V AC then goes through connector B (pins number A, B and C) to the PDU. The power relay also supplies 28 V DC to:
The PDU have a 3-pole relay which is operated by 28 V DC. The 28 V DC is (PDU operation signal) supplied from the control box to the 3-pole relay. The DC return is given through the related proximity switch when the XZ-single latch 32 is in the lowered position. This causes the 3-pole relay to send the 115/200 V AC to the PDU motor. Thus the power supply is stops when you lift the XZ-single latch 32. The power supply also stops when the joystick is back in the center/neutral position.
The electronic circuit card has the logical functions which are necessary for the commands of the joystick. When the joystick is pushed to a position, the AC reverse relay is set to the correct phase sequence. Thus the associated PDU (lateral or longitudinal) start. The electrical circuit card also keeps the last position of the reverse relay. The reverse relay only changes to the opposite position when a different direction for the PDU is set.

6. Operation
A. Load Operation for the Forward Cargo Compartment
The semi-automatic cargo loading system is prepared to move cargo into the cargo compartment when:
Power is now supplied to the cargo loading system and it can be put into operation. Before you onload the ULD, all the XZ-single latches 32 must be in the lowered position. Power is then available at the PDU for the movement of the ULD.
The first ULD can now be moved into the cargo compartment. In the door opening the entrance guides guide and align the ULD. At the same time the overridable Y-latch on each of the door sill latches is pushed down when the ULD moves over them. The Y-latches come up again when the ULD has gone over them. Thus the Y-latches prevent an accidental roll-out of the ULD.
When the ULD is in the ball mat area, the lateral PDU moves it. The joystick controls the lateral PDU. When you push the joystick to the IN position and hold it, then power is supplied to the lateral PDU. This causes the roller of the PDU to turn in the IN direction and the drive roller moves up to touch the base of the ULD. The drive roller moves the ULD across the cargo compartment until it engages in the YZ-latches and YZ-guide rails which stop it. The drive roller below the ULD turns until the joystick is released and goes back to the center/neutral position. Thus the power supply to the lateral PDU is stopped and causes the drive roller to go down.
To move the ULD in the ball mat area to the rear of the cargo compartment, push the joystick to the AFT position and hold it. Power is supplied to all of the longitudinal PDU, this causes their rollers to turn and the drive roller to come up. The ULD then moves to the rear of the cargo compartment from one PDU to the next until the ULD engages the endstops. The rollers of the longitudinal PDU turn until the joystick is released and goes back to the center/neutral position. The YZ-latches keep the ULD aligned while the ULD moves into the loading position.
When the ULD is in position, you lift the XZ-single latch 32 in front of it manually to hold the ULD. When you lift the XZ-single latch 32, the proximity switch below the latch operates and stops the power supply to the related PDU. The PDU is now isolated from the power supply. When you load the next ULD, the PDU below the ULD already in position does not run.
When the last ULD is loaded and in position in the ball mat area, you lift the YZ-latch on each of the door sill latches. The YZ-latch locks and holds the ULD in the ball mat area. When the YZ-latch is in the lifted position, the related limit switch stops the power supply to the cargo loading system. The cargo loading system is then electrically isolated. Set the POWER ON/OFF switch to OFF and the POWER LIGHT goes off.
The semi-automatic cargo loading system is prepared to move cargo into the cargo compartment when:
- the YZ-latch of each door sill latch is in the lowered position
- the POWER ON/OFF switch is in the ON position
- the POWER LIGHT is on.
Power is now supplied to the cargo loading system and it can be put into operation. Before you onload the ULD, all the XZ-single latches 32 must be in the lowered position. Power is then available at the PDU for the movement of the ULD.
The first ULD can now be moved into the cargo compartment. In the door opening the entrance guides guide and align the ULD. At the same time the overridable Y-latch on each of the door sill latches is pushed down when the ULD moves over them. The Y-latches come up again when the ULD has gone over them. Thus the Y-latches prevent an accidental roll-out of the ULD.
When the ULD is in the ball mat area, the lateral PDU moves it. The joystick controls the lateral PDU. When you push the joystick to the IN position and hold it, then power is supplied to the lateral PDU. This causes the roller of the PDU to turn in the IN direction and the drive roller moves up to touch the base of the ULD. The drive roller moves the ULD across the cargo compartment until it engages in the YZ-latches and YZ-guide rails which stop it. The drive roller below the ULD turns until the joystick is released and goes back to the center/neutral position. Thus the power supply to the lateral PDU is stopped and causes the drive roller to go down.
To move the ULD in the ball mat area to the rear of the cargo compartment, push the joystick to the AFT position and hold it. Power is supplied to all of the longitudinal PDU, this causes their rollers to turn and the drive roller to come up. The ULD then moves to the rear of the cargo compartment from one PDU to the next until the ULD engages the endstops. The rollers of the longitudinal PDU turn until the joystick is released and goes back to the center/neutral position. The YZ-latches keep the ULD aligned while the ULD moves into the loading position.
When the ULD is in position, you lift the XZ-single latch 32 in front of it manually to hold the ULD. When you lift the XZ-single latch 32, the proximity switch below the latch operates and stops the power supply to the related PDU. The PDU is now isolated from the power supply. When you load the next ULD, the PDU below the ULD already in position does not run.
When the last ULD is loaded and in position in the ball mat area, you lift the YZ-latch on each of the door sill latches. The YZ-latch locks and holds the ULD in the ball mat area. When the YZ-latch is in the lifted position, the related limit switch stops the power supply to the cargo loading system. The cargo loading system is then electrically isolated. Set the POWER ON/OFF switch to OFF and the POWER LIGHT goes off.
B. Unload Operation in the Forward Cargo compartment
The semi-automatic cargo loading system is prepared to move cargo out of the forward cargo compartment when:
Power is now supplied to the cargo loading system and it is ready to operate.
Before you unload the first ULD, lower the Y-latch on each of the door sill latches. The actuating mechanism lowers the Y-latches electrically when you push the DOOR SILL LATCH switch to DOWN and hold it. When the Y-latches are in the lowered position, the ULD in the ball mat area is ready to unload.
When you push the joystick to the OUT position and hold it, power is supplied to the lateral PDU below the ULD. This causes at the same time the drive roller of the PDU to turn in the out/unload direction and move the drive roller to up and to touch the base plate of the ULD. Thus the drive roller moves the ULD out of the cargo compartment. The entrance-guides in the door opening align and guide the ULD out of the Compartment.
When the ULD is over the door sill, you can release the DOOR SILL LATCH switch. The Y-latches then come up until they touch the ULD base plate. When the ULD has moved fully over the door sill, the Y-latches continue to lift until they are in the upright position. Thus the Y-latches prevent an accidental roll-out of the next ULD to be unloaded.
The drive roller of the PDU turns until the joystick is released and goes back to the center/neutral position. Then the drive roller of the lateral PDU stops and lowers.
To unload the ULD aft of the ball mat area, you must manually lower the XZ-single latch 32 in front of it. When the XZ-single latch 32 is in the lowered position, the proximity switch below the latch is operated. Power is now available to the related longitudinal PDU below the ULD. When you push the joystick to the forward position and hold it, power is supplied both to the PDU related to the lowered XZ-single latch 32, and to the longitudinal PDU in the ball mat area.
The ULD then moves in the forward direction onto the ball mat area from one longitudinal PDU to the other. The ULD stops when it engages the fixed Y-guide. When you release the joystick, it goes back to the center/neutral position and stops the power supply to the PDU. To move the ULD out of the ball mat area you must do the same unload procedure as described for the first ULD. The last ULD moves out of the cargo compartment as specified for the ULD before.
When the last ULD is unloaded, you must manually lift the YZ-latch on each of the door sill latches. The YZ-latches lock in the lifted position and the related limit switch stops the power supply to the cargo loading system and the POWER LIGHT goes off. Set the POWER ON/OFF switch to OFF.
The semi-automatic cargo loading system is prepared to move cargo out of the forward cargo compartment when:
- The POWER ON/OFF switch is in the ON position.
- The YZ-latch on each of the door sill latches is in the lowered position and the POWER control light is on.
Power is now supplied to the cargo loading system and it is ready to operate.
Before you unload the first ULD, lower the Y-latch on each of the door sill latches. The actuating mechanism lowers the Y-latches electrically when you push the DOOR SILL LATCH switch to DOWN and hold it. When the Y-latches are in the lowered position, the ULD in the ball mat area is ready to unload.
When you push the joystick to the OUT position and hold it, power is supplied to the lateral PDU below the ULD. This causes at the same time the drive roller of the PDU to turn in the out/unload direction and move the drive roller to up and to touch the base plate of the ULD. Thus the drive roller moves the ULD out of the cargo compartment. The entrance-guides in the door opening align and guide the ULD out of the Compartment.
When the ULD is over the door sill, you can release the DOOR SILL LATCH switch. The Y-latches then come up until they touch the ULD base plate. When the ULD has moved fully over the door sill, the Y-latches continue to lift until they are in the upright position. Thus the Y-latches prevent an accidental roll-out of the next ULD to be unloaded.
The drive roller of the PDU turns until the joystick is released and goes back to the center/neutral position. Then the drive roller of the lateral PDU stops and lowers.
To unload the ULD aft of the ball mat area, you must manually lower the XZ-single latch 32 in front of it. When the XZ-single latch 32 is in the lowered position, the proximity switch below the latch is operated. Power is now available to the related longitudinal PDU below the ULD. When you push the joystick to the forward position and hold it, power is supplied both to the PDU related to the lowered XZ-single latch 32, and to the longitudinal PDU in the ball mat area.
The ULD then moves in the forward direction onto the ball mat area from one longitudinal PDU to the other. The ULD stops when it engages the fixed Y-guide. When you release the joystick, it goes back to the center/neutral position and stops the power supply to the PDU. To move the ULD out of the ball mat area you must do the same unload procedure as described for the first ULD. The last ULD moves out of the cargo compartment as specified for the ULD before.
When the last ULD is unloaded, you must manually lift the YZ-latch on each of the door sill latches. The YZ-latches lock in the lifted position and the related limit switch stops the power supply to the cargo loading system and the POWER LIGHT goes off. Set the POWER ON/OFF switch to OFF.
C. Manual Load/Unload Operation of the Forward Cargo Compartment
If an electrical malfunction occurs, you can load/unload the ULD manually. You can lower and lift the Y-latches on the door sill latches manually with the DOOR SILL LATCH LEVER.
