Page 4: Introduction
2. Introduction The DSP-100 vehicle detector has been specifically designed to handle most traffic applications and is very tolerant of noise and cross-talk conditions. Working on virtually any size loop, the DSP-100 tunes itself automatically and provides constant tracking to deal with environmental changes. The DSP-100’s inherent noise filtering algorithms allow it to work reliably in almost any electrical situation. -

4. Features and Functions Detector Reset When any of the 6-position DIP switches (and the 12 DIP switches on the timing version) are changed, the detector will perform a detector wide reset. Depending how the internal jumper (J2) is set, the LEDs will blink differently. If the jumper is installed indicating fail-safe operation, both LEDs will blink 500 milliseconds on and off for two seconds. -

has failed. The fail-secure mode is useful in counting detectors, speed detectors, and high-security areas or installations where containment is needed. A jumper (J2) on the PC board inside the unit determines whether the detector operates in fail-safe or fail-secure. All DSP-100 detectors come with the jumper installed giving fail-safe operation. -
Page 9: Fail Memory Operation
Fail Memory Operation Normal operation during a loop failure is the green Power LED indicating what type of loop failure (open, short, or large ΔL/L). During the loop failure, the red Detect LED and the output will be active for fail-safe operation or inactive for fail-secure operation. -
Page 10: Delay Inhibit/Extend On Green (Timing Versions Only)
Figure 5: Output with Extension Figure 6: Output with Delay and Extension Delay Inhibit/Extend on Green (Timing versions only) Normal operation always honors any programmed extension time. By removing jumper J1 inside the detector, and connecting the AC green input for that phase to connector pin J (Delay Inhibit), the DSP-100 can be set to extend only during the green interval. -
Page 11: Indicators
Indicators The DSP-100 is equipped with two LED indicators: Power (Green) and Detect (Red). Power LED – The green power LED indicates these possible states: The voltage applied to the detector is insufficient. The LED will be off. Reset in Fail-safe At the start of a reset event (a DIP switch change, sensitivity change, or power cycle) the LED will turn off for 500 milliseconds, on for 500 milliseconds, off for 500 milliseconds, off for 500 milliseconds, and then... -
Page 12: Figure 8: Power Led States
Figure 8: Power LED States Detect LED – The red detect LED is used to display the status of the A output. There are several different statuses that can be displayed on this LED: No vehicle present in the detection area. Reset in Fail-safe At the start of a reset event (a DIP switch change, sensitivity change, or power cycle) the LED will turn off for 500 milliseconds, on for 500... -
Page 13: Figure 9: Detect Led States
Extension Interval A vehicle was detected but the detection zone is now empty. When the detection area becomes vacant, the extension timer will start and the output will continue to be activated. During this interval, the LED will blink quickly at 50 milliseconds on and 50 milliseconds off. If another vehicle enters the detection area during this interval, the extension time is cancelled and the LED will return to the solid state. -
Page 14: Installation
Installation Detector Installation Location: The detector should be installed in a weatherproof location that is near the loop. Ideally, a technician should be able to see the loop and the detector at the same time. Mounting: The detector will function when mounted in any orientation. The unit is designed to simply sit on a shelf. - Page 15 inductance should be twice the lead-in inductance. To approximate the loop inductance, use the following formula: L = (P / 4) x (N + N Where: L = Loop Inductance in microhenries (µH) P = Perimeter of loop in feet N = Number of turns in the loop For example, a typical 6’x6’...

Page 16: Figure 10: Loop Installation
Backer Rod Piece Loop Wires Saw Cut Figure 10: Loop Installation The corners of the loop should be crosscut at a 45° to help prevent damage to the wire insulation during installation and temperature cycling. The angled cuts should be at least 9” back from where the corner would be. The saw cuts should not go any further than necessary to ensure that the saw slots are at full depth where they meet. - Page 17 wire at the bottom of the saw slot allows the loop sealant to provide the maximum amount of protection possible from foreign object penetration. Never use a continuous piece of backer rod over the loop, as this would prevent the loop sealant from encapsulating the loop wire. The loop sealant used should be appropriate for the roadway surface that was cut.

Configuration Basic DIP Switches The front panel DIP switches facilitate easily changing most of the operating parameters of the DSP-100 detector. When a DIP switch is moved toward the numbers printed on the DIP switch, the switch is in the OFF position. -

Page 21: Wiring
Wiring The wiring for each loop circuit must be kept twisted to provide the most reliable operation. Wire nuts should never be used for any connection in the loop circuit. Connector: Standard 10-pin MS pin assignments for a NEMA TS1 single-channel shelf-mount detector are shown below. -
Page 22: Troubleshooting
7. Troubleshooting No Power LED The first step is to ensure that the correct model of the detector is being used for the installation. Ensure that the wiring is correct and the correct voltage is being used. Use a meter to measure the voltage applied to the detector. The AC voltage should be above 100V AC If the correct voltage is applied and the power LED is not on, replace the detector. -
Page 23: Power Led Shows Two Quick Flashes Once Every Two Seconds
If a loop is connected to the correct pins of the detector, disconnect the loop and using an ohmmeter, check the resistance of the loop circuit. If the resistance is below 0.2 ohms there is a short in the loop circuit. The resistance will typically be 0.5 ohms to 1.5 ohms. -
Page 24: Detect Led Will Not Come On With A Vehicle Present
The best way to check for any of these issues is to use a megohmmeter (commonly referred to as a megger). Disconnect the loop wires in question from the vehicle detector and any other electronic equipment. Connect one lead of the megger to one end of the loop wire and the other lead to earth ground. Measure the resistance. For accurate measurements the ground and the loop should be wet or at least damp (use a hose or a bucket of water if needed to get the area wet). - Page 25 If the channel sensitivity is set to 7 and the red LED still does not come on and you have another operating detector in the same box, swap the loops between a working detector and a failing detector. If the problem follows the loop the loop is the problem.
