Installation Guide

• Connect this expansion unit to a compatible main amplifier in the same group.
• Mount the unit on a DIN rail or bracket inside a clean control cabinet.
• Wire the 24 VDC supply within the 10 to 30 VDC range and observe correct polarity.
• Connect the PNP output to loads below 100 mA.
• Set LIGHT-ON or DARK-ON mode before production starts.
• Adjust the timer from 1 ms to 9,999 ms to match your machine cycle.
• Keep the expansion group at 17 units or fewer, counting a two-output unit as two.
• Set interference prevention for 0 to 4 units based on mode and sensor head.
