BASE LD-1250-LV Loop Detector for Detection of Vehicles, Inductive Loop
The front panel 7-segment LED DEFLECTOMETERTM provides visual feedback and assistance for setting the correct sensitivity, reading the frequency of the loop, reporting Loop Faults, and indicating Delay & Extension Timing functions.
With a typical size vehicle over the roadway loop, the DEFLECTOMETERTM functions as a Sensitivity Meter. The optimum sensitivity setting should provide a reading of 5 . You can adjust the DEFLECTOMETERTM reading by using the front panel UP or DOWN sensitivity buttons. Automatic quantitative feedback of the loop system operation ensures that the detector is set to the most optimum sensitivity level to detect ALL vehicles, including motorcycles and high-bed vehicles.
Following power-up or reset, the DEFLECTOMETERTM will indicate a 2 or 3 digit number (quickly flashes) that indicates the loop frequency of the loop & loop network. Keeping your loops separated by at least 5 KHz avoids crosstalk problems and future service calls.
Ten (10) Levels of Sensitivity:
10 levels of sensitivity (0 to 9) can be easily set using the UP or DOWN push buttons.
Two Models Cover ALL Voltages:
BASE LD-1250-LV operates on 12VDC, 24VDC, and 24VAC BASE LD-1250-HV operates on 120VAC and 240VAC
Advanced Loop Diagnostics:
The Loop Fault Monitor continually checks the integrity of the loops and will report and store three types of loop faults; Open Loops, Shorted Loops, and 25% sudden changes in inductance.
Loop Fault Memory:
The Loop Fault Memory uses internal Non-Volatile memory to store and display the current and previous loop faults utilizing the front panel Loop Fault LED and DEFLECTOMETERTM. A power loss or reset will not delete this memory. A MUST FOR TROUBLESHOOTING!
Call Output Memory:
The detector will not drop a Call state if power is lost for a minimum of 4 seconds or less.
Delayed & Extended Detection:
A 2-second CALL Delay time and 2, 5, or 10-second CALL Extension time can be provided.
