Acusensor 3
____________________________________________________________________________________________
D. If you install an Acusensor 3 in a place where
rain falls and puddles form, or excessive auto
mobile exhaust or insects accumulate, the
Acusensor 3 may malfunction. To avoid this,
lower the sensitivity.
(See page 11 in this Instruction Manual.)
E. If you have a short split curtain, flowerpot or any
other items that may shake in the detection area,
the Acusensor 3 may false activate. Move the
items out of the detection area.
F. If a door mat is used on the floor, a shop sign or a
shopping basket is put in the detection area, do
not set the standstill object detection time to
“forever detection”. If the items in the detection
area move a bit, the door may be held open.
G. If two or more Acusensor 3s are used
close to one another, ghosting may occur
due to mutual interference. Be sure that
every Acusensor 3 has a different
mutual interference mode. (See page 10
in this Instruction Manual.)
H. Too much reflected light off the floor may
reduce the sensitivity causing the
Acusensor 3 to malfunction. Adjust depth
and width area accordingly.
I. If the Acusensor 3 is installed in a place where rain or snow falls on it,
damage to the sensor may occur. In this case, use Acusensor 3 Rain
Cover ( P/N 14-13783 ).
J. If the background condition within the infrared detection area sudden-
ly changes due to a strong snowstorm, the Acusensor 3 could ghost. In
this circumstance, choose the Snow mode or lower the sensitivity. After
the sensor is set to Snow mode, make sure the detection area is
properly set. (See page 11 in this Instruction Manual.)
