Communication & Expansion

• The LV-N10 has no built-in ports and supports no protocols directly.
• It becomes network-compatible when you pair it with NU series network units.
• Communication expansion units from the NU series are available separately.
• This design keeps the amplifier compact while allowing fieldbus integration when needed.

Installation Guide

• Mount the unit on a DIN rail or use the dedicated mounting bracket for stable positioning.
• Connect the 24 VDC supply within the 10 to 30 VDC operating range and observe polarity.
• Wire the NPN open collector output carefully and keep load current below 100 mA per output.
• Maintain at least 10 mm clearance around the unit when you stack multiple amplifiers.
• Derate the ambient temperature when you install several units side by side.
• Use the LIGHT-ON / DARK-ON switch to match your detection logic before power-on.
• Set the timer mode and time value between 1 ms and 9,999 ms for your application.
• Verify the response time mode matches your machine cycle for reliable detection.
