D-TEK Vehicle Loop Detector - Operating Instructions

We at EMX have designed the new D-TEK vehicle loop detector with the following objectives in mind:

1. Compact package to allow easy installation into small operator housings.

2. All the controls are accessible from the outside for easy installation and operation.

3. Integral loop conditioner is provided, to enable detector operation with marginal loops.

4. Provide all the features and controls necessary for a variety of applications.

5. Use metal housing for maximum durability and RF blocking.

6. Provide maximum surge protection on all inputs and outputs of the detector.

We took extra care to achieve and exceed these objectives. For example the controls are divided into two groups. The group on the front of the detector is for basic operation and the group on the back of the detector is for advanced settings. This way the more advanced settings are not visible to the casual user.

There is no skimping on the quality in the D-TEK detector. The housing is made from aircraft quality anodized aluminum. All the switches have gold plated contacts and are sealed for protection. The detector is protected by easily replaceable fuse, snubbing circuitry on the relay contacts, metal oxide varistor on the power input and triple protection on the loop input.

The D-TEK features are extensive and they include full loop diagnostics with frequency counter, 10 sensitivity settings, delay and extend features, "fail safe" and "fail secure" operation, automatic sensitivity boost, pulse or two presence relay operation and more.

Front Indicators

1. Green Led is ON - the detector is powered.

2. Red Led is ON - the detector detected a vehicle

3. Green Led is Blinking - the loop failed and is shorted or disconnected

4. Green Led is Blinking with two consecutive fast blinks - the loop failed in the past and now is working correctly.

5. Red Led is Blinking at the start of a vehicle detection - the Filter function is ON

6. Red Led is Blinking at the end of a vehicle detection - the Extend function is ON

7. Red Led is Blinking during a vehicle detection - 4 minute limited presence time has expired.

Note: Functions on pins 6 and 10 are reversed if DIP 4 is set to OFF

Front Controls

Reset This toggle switch when pushed momentarily down will reset the detector

Frequency Counter This toggle switch when pushed momentarily up will count the frequency

on the loop. This count is displayed by the Red Led blinks, each blink represents frequency of 10K Hz. Count between 3 to 13 blinks confirms that the loop detector is tuned to the loop.

Frequency This toggle switch controls the loop frequency. Set different frequencies

on adjacent loops. Verify frequencies with the frequency counter by counting the Red Led blinks.

Back Controls

Sensitivity This rotary switch controls the detector sensitivity. During normal

operation the sensitivity level is set to 3 or 4.
