The performance of the sensor can be negatively impacted if the sensor is
angled down, causing false detection from the ground. Any time the
sensor is not perpendicular to the ground, the performance should be
tested. In some instances, mainly with longer range models, the sensor
may need to be angled upward to reduce false detections from the ground.
Keep Out/Interference Zones
Metallic and any other strong radar reflecting objects must remain outside
of the keep out zones defined in Figure 11. If radar reflecting objects
reside within the keep out zones, testing must be performed to determine
their influence on the sensor’s performance.
Horizontal “Keep Out” Zone Vertical “Keep Out” Zone
Figure 11. Keep Out Zones
The sensor’s horizontal field of view is +/- 75 degrees and the vertical field
of view is +/- 10 degrees. For optimal performance, the sensor should
protrude beyond any other portion of the vehicle.
Important!
Before permanently installing the Sentry
™
on the vehicle, verify that the
selected sensor mounting location provides a clear detection zone. Take
the machine to a clear area, temporarily attach the sensor in the proposed
mounting location, apply power to the system, and verify that nothing is
being detected.
Sensor Mounting Procedure
PRECO Electronics
®
supplies two different brackets for the Sentry
™
radar
sensor. If the provided 90° bracket shown in Figure 12 is not appropriate,
an adjustable mounting bracket is available, shown in Figure 13.
