3.2.24.3. JAM DETECTION SENSORS
Jam detection sensors and timers shall be provided to detect baggage jams. The sensors and control logic shall differentiate
Ramstein AB – Appendix A – Page 13 between long baggage items and jams. Jam detection sensors shall be located at or near the discharge end of all conveyors prior to passing through a wall opening and at other areas where jams are likely to occur. The jam timer shall be manually adjustable over a minimum range of 0 to 15 seconds on maximum 1-second intervals. If a jam is detected (baggage blocks the jam sensor for the timed period), that conveyor and all upstream conveyors shall stop. An indicator light shall illuminate on all control panels and shall remain illuminated until the jam has been cleared and the fault has been reset as specified in
3.2.26.5. If jammed, the conveyor shall not restart until the jam has been cleared. Once the jam is cleared, the jam detection circuit shall be reset to extinguish the indicator light and start the upstream conveyors. A false jam indication shall not be generated by baggage blocking the sensor if the conveyor has stopped for reasons other than a jam being detected.
3.2.24.4. AUTOMATIC SYSTEM STOP SENSORS
Automatic stop sensors shall be provided to automatically stop a powered conveyor section when not in use. The time interval shall be manually adjustable over a minimum range of 1 to 15 minutes on maximum intervals of 1 minute. Sensors capable of detecting all baggage sizes shall be used. After a time interval suitable to ensure that the last piece of baggage reaches its destination, the timing device will time out and the conveyors not necessary to transport baggage shall stop. Once the conveyor times out, it shall be able to start again without resetting. The timing devices shall stop timing if any portion of the conveyors required to transport baggage to the next conveyor section is not operating due to a jam, motor overload or emergency stop.
3.2.24.5. OVERHEAD DOOR POSITION SENSORS
A door position sensor shall be provided at each overhead door.
The sensor shall ensure that the overhead door is in the fully opened position (not blocking the wall opening) prior to conveyor movement to transfer baggage between the wall opening.
If the sensor detects that the door is not fully opened, the conveyor shall not operate. A fault light shall illuminate as specified in 3.2.25.5. If the overhead door is lowered during operation, the conveyor shall immediately stop and the specified fault light shall illuminate.

4. QUALITY ASSURANCE PROVISIONS
4.1. INSPECTIONS
The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of the cover purchase description. These inspections shall be completed as part of the system checkout test and again as a part of the quality conformance test.
4.2. TESTS
The following tests shall be performed on the system as part of the system checkout test and again as a part of the quality conformance test.
No. Paragraph Description
1. 3.1. Test to ensure the system can handle items between the minimum and maximum weights and sizes as specified. The conveyors shall be loaded with 10 baggage items. At least one item shall have the minimum weight and size and one item shall have the maximum weight and size. If any baggage fails to complete a run of the system, without human intervention, the system fails the test.
2. 3.2.1.1. Verify all scales are certified. Load the scale conveyors with known test loads. Place the test loads at different locations on the scale conveyors. If the scales are not certified or if the scales do not provide the correct weight of the test loads within 0.5 percent, the scales and scale conveyors fail this test.
Ramstein AB – Appendix A – Page 22
3. 3.2.4. Test to ensure the conveyors are capable of carrying a live load capacity of 100 pounds per linear foot (150 kg/m) with a maximum load of 150 pounds (68 kg) per bag. With the conveyor fully loaded, (total linear feet or meters of conveyor x 100 pounds per linear foot or 150 kg/m), place five pieces of baggage adjacent to each other that have the density of approximately 100 pounds per linear foot (150 kg/m). Operate the conveyor for 30 minutes in both directions. If the conveyor was not able to operate carrying a live load, the conveyors fail the test.
4. 3.2.4. Test to ensure the conveyors are capable of starting and stopping under a fully loaded condition. Repeat the application in test number 3. During the 30 minutes, the conveyor shall be stopped for 30-second intervals every 5 minutes then restarted. If the conveyors cannot start, stop and operate carrying the live load capacity, the conveyor fail the test.
5. 3.2.5. Test to ensure that the scale and feeder conveyors operate at 60 + 5 feet (18300 + 1500
mm) per minute under maximum load. Load both the scale and feeder conveyor with 100 percent capacity (total linear feet or meters x 100 pounds/linear foot or 150 kg/m). Start the conveyors. Depress the start button and let the baggage move 6 feet (1830 mm). If the time to move 6 feet (1830 mm) is greater than
6.0 + 0.5 seconds, the conveyors fail the
Ramstein AB – Appendix A – Page 23
6. 3.2.5. Test to ensure that the takeaway conveyors operate at 90 + 5 feet (27400 mm + 1500 mm) per minute under maximum load. Load each piece of conveyor with 100 percent capacity (total linear feet or meters x 100 pounds/linear foot or 150 kg/m). Start the conveyor. On the takeaway conveyor, move a piece of baggage a distance of 90 feet (27400 mm). If the time to move 90 feet (27400 mm) is greater than one minute + 3.5 seconds, the conveyor fails the test.
7. 3.2.10. Check the belt location on each section of the conveyor. Run the conveyor for four hours, starting and stopping the conveyor several times. Re-inspect the belt locations. If any of the belts show damage, do not maintain even clearance between side rails, become less taught, or track to one side, the conveyors fail this test.
8. 3.2.23. Test to ensure the sensors operate in the manner described in 3.2.23. and its subparagraphs. While the conveyor is in operation, place a piece of baggage on each of the conveyors. Verify that the conveyors automatically transfer the baggage as specified. If any sensors fail to detect baggage or prevent the system from operating as specified, the conveyor fails the test.
9. 3.2.23.1. Transfer a bag from the scale conveyor to the feeder conveyor by activating the foot pedal.
With the bag now located on the feeder conveyor and the takeaway conveyor not running, activate the feeder conveyor using the foot pedal. If the start-up warning devices activate during the transfer from the scale conveyor to the feeder conveyor, if the start-up warning devices fail to activate, or the takeaway conveyor fails to activate after the horn stops, the conveyor fails this test.
Ramstein AB – Appendix A – Page 24
10. 3.2.23.2. Test the takeaway sensors. Transfer a piece of baggage on the takeaway conveyor starting from a feeder conveyor. If follow-on takeaway conveyor sections do not activate prior to the baggage arriving on the section or if the startup warning device sounds for the activation of follow-on conveyor sections, the conveyor fails this test.
11. 3.2.23.2. Test the takeaway sensors. Place the maximum number of pieces of baggage that can fit on the takeaway conveyor section in each Baggage Build-Up Area on the takeaway conveyor before each curve. Transfer the baggage towards the Baggage Build-Up Area.
