Banner K80 Pick-to-Light EZ-LIGHT - Manual (Page 2)

Overview
The solid-state output interfaces to a system controller, which is pre-programmed for a specific sequence of tasks. Mounted in or near
each bin in an assembler’s work station, the sensor job light signals the assembler:
• Which bins contain items to be picked in a given operation; and
• In what order they should be picked.
As the assembler takes a part in sequence and pushes the push-button, the sensor senses that the part was removed and it sends an
output signal to the controller. The controller then verifies if the correct part was taken and may respond by turning that job light OFF,
activating the job light of the next bin in the sequence.
If multiple parts are to be removed from one bin, the job light may remain ON until the appropriate number of signals is returned to the
controller. If an incorrect part is selected, the control system may be wired to signal an alarm for the assembler and/or a supervisor, or it
may be programmed to interpret the action as a call for parts.
Indicator and Output Behavior
NOTE: "C3" and "C4" models as referenced in the table pertain to a part of the product model number, imme-
diately preceding the QPMA designation.
