Fine Adjustment
To perform fine adjustment with target present push “Teach
Button” or “Momentary Push Button” for eight seconds until
the yellow LED flashes quickly. The threshold is set to a
minimum sensing setting. After teaching the sensor the
yellow LEDs will flash quickly when target is present and off
when absent. A solid LED during target presence denotes
inability to use fine adjustment due to misaligned sensor or
incompatible target/background properties.
Remote Teach with Dark Operate Mode
To remote teach with the Dark Operate Mode, a 2.2k Ω resistor
must be added to avoid short circuits in the power supply
when the teach mode is active.
