Self-diagnostic Function
With this function, the E3S-A checks changes in environmental 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.
External Diagnostic Input Function
To switch the emission off, short-circuit the pink and the blue cords of the emitter of
the E3S-AT or the E3S-AR with the NPN output feature. For the E3S-AT or the E3SAR with the PNP output feature, short-circuit the pink and the brown cords. With this
function, the operating status can be checked before operation.

is expected if the
temperature fluctuation is within
±10% of the primary temperature.
The self-diagnostic alarm
output alerts
the user to this
state if it continues for 0.3 s.
0.8 to 1.0 Without light inci-
dent (red indicator: OFF)
0.8 or less Stable operating
state with no incident light: Stable
operation is expected in the rated temperature
range with the
green indicator
ON.
