Overview This document describes the PreView Sentry radar sensor manufactured ® ™ by PRECO Electronics , located in Boise, Idaho, USA. The document does ® not claim to cover all the possible applications or deployment areas for these devices. This document may be amended, corrected, and enhanced in keeping with the sensor development progress.
Figure 2. Adjustable Detection Zone The Sentry has multiple models with preconfigured detection zones: both ™ www.preco.com range and width of detection zone. Note: the website contains the most current data on radar sensor models. Sentry ST87 Series radar sensors include an 8-pin Deutsch connector ™...
Figure 4. Detection Zone 30 m The sensor is active and starts reporting detections within 300 milliseconds (ms) after power up. The Sentry performance is not affected by other PreView Sentry ™ ® ™ similar sensors operating in close proximity with each other.
The maximum operating current is approximately 1 amp, including any inrush current. Sensor Input The PreView Sentry ST87 series radar sensor provides an auxiliary input ®...

PRECO Electronics provides a variety of different cable lengths and ® configurations for the PreView Sentry radar sensor, as well as solution ® ™ kits of radar, cabling, and displays. Please contact PRECO Electronics ® a list of available cables and kits.
Regulatory Compliance The Sentry is compliant with the following countries/regions and their ™ regulations as of the published date of this manual. The sensor may be compliant in other countries/regions. Please check your local regulations. United States - FCC- Part 15.249 FCCID: OXZJCKP2016 ...
Installation Sensor Mounting The Sentry mounting location is important for proper system operation. ™ Ideally the sensor should be mounted on the rear of the vehicle as close to the center as possible at roughly 36” (1 m) above the ground. The sensor face should be perpendicular to the ground with the small end of the “V”...
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.
Figure 12. Provided SD-BK90 (90° Mounting Bracket) If mounting to the vehicle using the provided bracket, follow the procedure outlined below. 1. Select the appropriate sensor mounting location. 2. The standard mounting configuration is with the small end of the “V” graphic pointing down, as shown below.
Troubleshooting The troubleshooting below is for the most common PreView display. ® Refer to the particular display manual for errors code descriptions. Display Status LED is not illuminated. Verify that DC power (9-33 V) is applied to the sensor.
The Sentry operates by ™ transmitting low power electromagnetic energy. Any energy that strikes an object reflects a certain amount of this energy back to the PreView ® Sentry radar sensor. If the returned energy is of sufficient magnitude, it is ™...
