■ LIGHT AXIS ADJUSTMENT WITH FLASHING FUNCTION
E3X-A❏❏/-F❏❏/-VG❏❏
Stable Operation Indicator
(Green Indicator)
With this function, the E3X checks changes in environment
conditions (especially a change in the ambient temperature) and
self-diagnoses the resistance against the changes. The result is
shown by the indicators or an output signal.

■ SELF-DIAGNOSTIC FUNCTION
Light Reception Indicator
(Red Indicator)
Displays
● Stable Operation Indicator: Changes in environmental
conditions (changes in the ambient temperature, the
operating voltage, or the volume of dust) are checked and
the resistance against them are self-diagnosed. The result
is shown via the indicator.
● Light Reception Indicator: The amount of light received is
shown by this indicator.
Output:
● The resistance against changes in environmental
conditions is shown by the indicator and the result is
output.
1. Set the mode selector to SET.
*If the self-diagnostic output is ON when the sensing object is
moving at low speed, use the E3X with an ON-delay timer circuit.
