5.7 TAKEAWAY BAGGAGE CONVEYOR SENSORS

An item present sensor shall be provided before the start of each section of the takeaway conveyor. This will turn on the next section of conveyor. Once baggage activates a curve, the next section of conveyor beyond the curve shall start. The startup warning devices shall not activate due to the starting of the follow on conveyor section.

5.8 X-RAY LEADING INTERFACE SENSOR

A sensor shall be located in front of the X-ray machine to stop bags from going directly onto the X-ray machine conveyor. An operator will send the bags through the X-ray machine one at a time.

5.9 JAM DETECTION SENSORS

Jam detection sensors shall be located near the discharge end of all straight conveyors that feed a powered curve. Jams shall be detected by means of a sensor and timer. The jam timer shall be manually adjustable from 0-15 seconds. If 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. 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.

5.10 AUTOMATIC SYSTEM STOP SENSORS

An automatic system stop sensor shall automatically stop a powered conveyor section when not in use. After a time interval (1-15 minutes, manually adjustable), suitable to ensure that the last piece of baggage reaches its destination, once the timing device times out the conveyor 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 system required to transport baggage to the next conveyor section is not operating due to a jam, motor overload, or emergency stop.

5.11 EMERGENCY STOP BUTTONS
