Indicators
•
The operation indicator is lit when the sensing object is near the
sensing distance.
•
The stability indicator is lit when the sensing object position is
less than 95% or more than 107% of the sensing distance. The
stability indicator indicates the range in which each sensing
object is detected smoothly.

Adjustment
Obtain the
sensing distance
X from the set
distance S
divided by 0.8.
Determine S so
that X will be
less than the
maximum
sensing
distance.
Locate the
Sensor so that
the distance
between the
Sensor and
sensing object is
X. Turn the
sensitivity
adjuster
clockwise until
the operation
indicator is lit.
Return the
Sensor to the
previous position
so that the
distance
between the
Sensor and
sensing object is
S. Secure the
position of the
Sensor to
complete the
sensitivity
adjustment.

Note:
If the E2C Amplifier Unit malfunctions due to radical ambient temperature changes, shorten the distance between the Sensor and
sensing object to 80% maximum of the set distance.
