External Diagnostic Input Function
With this function, light projection can be stopped when desired.
The
operation of the sensor can be checked with this function before
the
E3X is placed into actual operation.
E3X-A
Light is emitted from the projection fiber head when the self-diag-
nostic
input is ON. The sensor, however
, will not operate.
E3X-F
No
light is emitted
from the projection fiber head when self-diagnos
-
tic
input is ON.
