4-4 About the Light Interference Prevention Connection
4-4-1 What is the Light Interference Prevention Connection?
Be sure to read the “Safety Light Curtain SL-C Series Instruction Manual” if you plan to use this feature. By
establishing a light interference prevention connection, you can prevent light interference between 2 or more
sets of SL-C Series that are connected to the SL-R11E. This feature is active when the total number of
connected SL-R11E units is 4 or less.
To enable the light interference prevention function, the power to the main SL-R11E units and sub SL-R11E
units must be turned on. (If the power supply of a sub unit is turned OFF during operation, this unit and the
inferior sub units to it go to lockout condition and their operations are stopped.)
