Maximum Analog Ranging
Analog sensing in the maximum range means
uti liz ing the entire 36" span (4"-40") and 72" span
(8"-80"). To adjust, set your target at the min i mum
range, either 4" or 8" and adjust P1 to 4mA. Move
the target to the maximum range and adjust P2 to
20mA. Re-check read ings and make ap pro pri ate
ad just ments, if necessary. See di a gram (B).
Inverted Analog Outputs
Inverted outputs means that the 4-20mA or 0-10V
output signal will decrease proportionally with
dis tance. To adjust, place your target at the
min i mum sensing distance and ad just P1 to 20mA.
Place your target at the max i mum sensing dis tance
and adjust P2 to 4mA. Re-check read ings and
make ap pro pri ate ad just ments, if nec es sary. See
diagram (C).
LED Operation
( Not e D)
The LED is green when the unit is powered up.
It will fade to red as a target is detected with
in creased intensity as more sig nal is be ing
re flect ed from the target. Note: Any color other
than green equals a workable signal level.

Op er a tion and Set-Up
Minimum analog ranging is when you desire to
have the full 4-20mA or 0-10V output over the
minimum 5 inch sensing span. 5 inches of
min i mum sensing span can be adjusted any where
in the sensing range. For example 10"-15" or
25"-30". To make this ad just ment, you place your
target at the minimum sensing range and adjust
P1 to 4mA. Then move your target to the
max i mum sensing range and adjust P2 to 20mA.
Re-check the readings and make appropriate
ad just ments, if necessary. See diagram (A).
