Adjustment
Set the MD adjuster to
the center between “Min”
and “Max.”
Locate the sensing
object in the adjustment
range of sensing
distance and turn the
sensitivity adjuster
clockwise slowly until the
operation indicator is lit.
Move the sensing object
for a necessary
differential travel
distance (i.e., 1% to 5%
of the rated sensing
distance) and turn the
MD adjuster
counterclockwise slowly
until the operation
indicator turns off. Then
move the sensing object
and check that the
Sensor detects the
object when the object is
in the sensing distance
range.
Shorten the distance
between the Sensor and
sensing object and fix
the position of the
Sensor where both the
operation indicator and
stability indicator are lit
to complete the
sensitivity adjustment.
Note:
1. If the E2C Amplifier Unit malfunctions due to radical ambient temperature changes, further shorten the distance between the Sen-
sor and sensing object to 80% maximum of the set distance.
2. The E2C-JC4A has no function to adjust differential travel. Therefore, take steps 2 and 4 only.

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 or counterclockwise
until the red 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. The green stability
indicator must be lit when the
sensing object is located within
the sensing distance and not lit
when the sensing object is
completely outside the sensing
distance.
Note:
If the E2C Amplifier Unit malfunctions due to radical ambient temperature changes, further shorten the distance between the Sensor
and sensing object to 80% maximum of the set distance.
A caution label is provided with the E2C Amplifier Unit. After completing sensitivity adjustment, affix the caution label over the adjuster hole of
the cover to prevent mis-operation of the E2C Amplifier Unit.
