Banner PVA Pick-to-Lights User Manual
PVA Pick-to-Light Array
Light screen for error-proofing of bin-picking operations
• Compact package, available in 4 lengths to fit many sizes and configurations of existing
parts bins
• Range up to 2 m (6.5 ft)
• Two-component system (asynchronous emitter and receiver) needs no sync wire or controller box.
• Emitters and receivers sold separately or in pairs for easy ordering.
• Two LEDs on each emitter and receiver indicate proper setup and system errors.
• Clearly visible green job indicator lights mounted on either side of emitter and receiver
housings; the light can be remotely controlled to initiate user action with a solid ON or
blinking condition
• Two frequency settings to prevent crosstalk in close-proximity, multiple-array installations
• Easy DIP-switch selection of light/dark operate, solid/flashing job light, A/B frequency,
and gate polarity for activating the job light indicator.
• Choose 2 m (6.5 ft) unterminated cable or 2 m (6.5 ft) cable with 4-pin Euro-style quickdisconnect connector.
• PNP or NPN receiver output, depending on model
• 12 to 30V dc operation
• Minimum resolution 35 mm (1.4 in)
• Wide beam pattern for easy alignment
• Heavy-duty protective brackets available
WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious
injury or death. This device does not include the self-checking redundant circuitry necessary to allow its
use in personnel safety applications. A sensor failure or malfunction can cause either an energized or deenergized sensor output condition.

Overview
The PVA Series Parts Verification Array is a simple, easy-to-use light screen suited to many part assembly and object detection applications.
The PVA has two components: an emitter and a receiver. The receiver's solid-state output interfaces to a system controller, which is preprogrammed by a supervisor for a specific sequence of tasks. Mounted so that the beams stretch across each bin in an assembler’s work
station, the PVA then signals the assembler (by means of easy-to-see job lights) which bins contain items to be picked in a given operation and in what order they should be picked.
As the assembler reaches into each bin, the system senses if the correct part has been taken, then signals the next bin in the sequence.
The system may be wired to signal an alarm for the assembler and/or a supervisor in the event an incorrect part is selected.
The major benefit of a PVA-driven system is increased efficiency, due to simplified job training, increased quality control (no skipped
components), and reduced rework and inspections. The PVA speeds the resumption of work after breaks and other distractions. And it is
ideal for multilingual workplaces where communication may be an issue.

Installation
Multiple sensor pairs located farther than the sensor's effective maximum range (approximately 2 m or 6.5 ft) from one another are unlikely to cause crosstalk problems. However, when multiple sensor pairs are mounted in a confined area, take care to avoid crosstalk between them. To avoid crosstalk:
• Alternate the relative position of adjacent emitter/receiver pairs.
• Alternate the Frequency configuration of adjacent pairs.
Mount emitter and receiver pairs parallel, with both cable ends pointing the same direction.
