- Page 1 LP D-TEK Vehicle Loop Detector Operating Instructions...
- Page 2 We have designed the new LP D-TEK vehicle loop detector with the following objectives in mind: 1. Low current consumption, maximum 9 mA current draw in fail safe or fail secure. 2. All the controls are accessible from the outside for easy installation and operation.
- Page 3 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.
- Page 4 DIP - Detector Functions Presence function is provided always by the presence relay output on pins 5, 6, and 10. These outputs are active when the detector detects a car. If there is a need for an additional presence output the Relay 2 can be configured as a second presence output by setting DIP 1 to ON position.
- Page 5 Troubleshooting Symptom Possible Cause Correction Green indicator is not ON No input voltage 1. Check voltage on pins 1 and 2. 2. Replace internal fuse 3. Check wiring to detector Green indicator flashes Loop wire shorted or 1. Check loop resistance on pins 7 and disconnected 8 it should be less than 5 ohms...
