Acuvision Instruction Manual
D.4.1) Setting up for Depth Coverage (continued....)
As a Presence/Threshold Sensor Only
When other sensors are being used for the activation function, it may not be desirable to reduce
the sensing coverage area of the Acuvision. Adequate threshold or swing zone coverage should
be achieved by setting the area lever to position #1 or #2. Coverage should always be checked
to be sure it is adequate. For best detection of slow moving pedestrians or objects, the
sensitivity option should be on Standard or High and the time set for 30 seconds.
The width and depth of coverage for an actual installation may vary from Table 1 & 2. This is
typically the result of:
1.
A variance in mounting height
2.
Normal manufacturing and component tolerances
3.
Variances in field measurements, procedures and conditions from ANSI standards.
4.
Use of spacers for mounting

D.4.2) Non-Detection Zone
It is possible to have a non-detection zone in the sensing pattern. Figure 2 shows how changing
the position of the lever affects the sensing pattern. White areas are non-detection zones.
In Position # 4, the non-detection zone is small enough that most objects will not go undetected.
With the lever in Position #5, it is possible for small stationery objects to go undetected.
However, if an object moves into one of the sensing zones the Acuvision will detect a change.

Note:
The above detection area dimensions are for reference only. Adjust sensor patterns to meet the specific
requirements of the installation.
