Qualstar XLS Series Installation Manual page 27

The curtain of light formed by the emitters and detectors allows the XLS to precisely
monitor all areas within the LRM and MEM cabinets, as follows:
• The beams of light at the rear of the cabinet can detect whether a cartridge is
protruding from a slot. If the door(s) are closed and one of these beams of light is
broken, the XLS prevents the handler from moving to avoid hitting a protruding
cartridge.
• The beams of light curtain at the front of the cabinet can detect when someone
reaches into the cabinet. If a door is open and one of these beams of light is
broken, the XLS detects and logs a potential inventory violation and
automatically scans the cartridges and drives in the affected area as soon as all
doors are closed.
