DU100 Vehicle Detector Diagnostic Unit

The DU100 Diagnostic Unit may be utilised in conjunction with Nortech standard 3-series inductive loop detectors, which have integral diagnostic capability.

Current operational and historical data are transferred from the vehicle detector to the DU100 by means of an optical link. Data transmission from the vehicle detector is continuous during normal operation. This allows diagnostics without service disruption. Received data is verified for integrity by means of a cyclic redundancy check (CRC) process, and then displayed on the LCD screen.

The DU100 Diagnostic Unit is indispensable for:

• Setting and verifying detector sensitivity
• Performance checks on loops and installation
• Checking intermittent failures through the historical data
• Eliminating any detector crosstalk
