1.2.7 Door and Light Curtain Sensors
Door
The XLS-810160 and XLS-810240 have a single door on the right side. The XLS-85000
MEM2 has a single door that opens on the front. All doors have windows for viewing robot
operations and the LRM’s have front windows. There are also viewing windows on the
side panels.
Light Curtain Assembly
The light curtain , also known as the “Inventory Sentry,” consists of a series of infrared
emitters and detectors arrayed throughout the XLS. The emitters project small beams of
infrared light that is not visible to the naked eye toward corresponding detectors.
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 is 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 the 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 the
door is closed.
