1. ground the induction loop detectors are designed for detecting vehicles metal masses and triggering an action They can be used for controlling parking lot barriers warehouse rolling shutters garage doors or also for detecting vehicles in front of automatic traffic lights The 2 channel models can also detect the direction in which vehicles are travelling Special Features e Automatic self adjustment on the loop connected as well as after altering the unit s settings This guarantees that the unit is easy to put into service and to operate e Maintenance free thanks to automatic compensation of atmospheric and environmental influences e Adjustable sensitivity and automatic sensitivity boost to reliably identify various vehicle types e Output via floating relay contacts with a max contact rating of 5 A 230 V AC e Indication of operating state and malfunctions via LEDs Operating Instructions Functional Restrictions e The feeder cable must be twisted with approx 20 turns per meter Cross talk e The sensitivity of the loop reduces the If the loops of two detectors are located directly longer the feeder cable is The feeder next to each other then the magnetic fields can cable should therefore be as short as overlap and cause interference resulting in possible and not exceed 100 meters in malfunctions This can be avoided by taking the length following measures e Set different working frequencies on t2. A loop B is still occupied The same principle applies correspondingly when the loops are driven onto from the other direction The relay output jumpers PP1and PP2 cannot be adjusted in this operating mode but are permanently switched to pulse operation PULSE Operating Instructions SENS Setting the Sensitivity The sensitivity can be set for various vehicle types The settings MED HIGH or MED LOW are optimized for the majority of applications For vehicles with minimal metal mass e g bicycles the sensitivity can be set at HIGH Switches 3 4 sensitivity channel 1 Switches 5 6 sensitivity channel 2 E OFF CE ON SENS 1 3 LOW 3 MED AE A C HIGH 3 CE MED 3 CE JE LOW ta HIGH SENS 2 5E ow 5E MED 7 6 CE HIGH 5 CE MED 5 C IGH m_ LOW C E Change in inductance AL L in the case of various vehicle types loop 2m x 1m 3 windings Bicycle 0 02 Motorcycle 0 12 Truck 0 4 Car gt 1 0 ASB Automatic Sensitivity Boost If the ASB is switched on when a vehicle is detected the sensitivity of the detector is automatically increased to the maximum In this way long truck combinations and vehicles with high set chassis can be reliably identified and premature closing e g of a barrier prevented Switch 7 ASB ASB 7m orff 7 CE ON Example signal sequence for long truck combinations with and without ASB Loop AorB Signal yes with ASB no without ASB rem jes eA no PRES Signa
3. Operating Instructions 1 3 AB PRESENCE MODE Loop A B RLY A RLY B In the AB PRESENCE MODE a direction dependent signal is issued which can be used if the presence of a vehicle on loop B is to be signalled Cases for application can be for example parking barriers or gates with an automatic timer function which should not be allowed to close until a vehicle has completely left the closing area loop B Principle If a movement from loop A to loop B takes place then only output A in accordance with the diagram is switched After loop A has been activated output A remains switched Technical Data Frequency range as long as loop B is occupied Not until loop B has been completely vacated does the output signal decline again The same principle applies correspondingly on driving onto the loops from the other direction The relay output jumpers PP1and PP2 cannot be adjusted in this operating mode but are permanently switched to continuous operation PRESENCE Cleaning e Carefully wipe down the casing with a damp lint free cloth e Do not use any cleaning agents containing solvents These pose a health risk and can damage the casing surface Disposal Waste electrical products and batteries may not be disposed of with household waste Dispose of the waste product via KH a collection point for electronic scrap or via your specialist dealer Put the packaging material into a LI containe
4. he Installing the Induction Loop detectors The closer the loops are to each other the greater the difference in frequency should be e Increase the distance between the two loops gt 2 meters recommended e If the feeder cable is laid next to other electric cables it should be shielded This shielding only needs to be earthed on the detector side e The length of the loop is determined by the width of the road to be monitored It should extend up to 300 mm from each edge of the road fig 4 Fig 4 Edge of Reinforcements Steel reinforcements under the road can adversely affect the performance of the loop detection system This interference can be reduced by taking the following measures Groove E E S S e Add two more windings to the loop e Select the maximum distance possible between the steel reinforcement and the loop cable Corner cut at 45 angle to avoid damaging the cable A Direction of traffic Installation Instructions e Given the size of loop stated below the following number of windings are required Detector e Attach the detector in a suitable weather Size of loop Number of windings protected location 3 6m 4 6 10m 3 Feeder cable and loop cable 10 30 m 2 e The feeder cable and loop cable should be of the same material Junction points Place the loops in the grooves which must be avoided accommodate the feeder cable a groove e The cable must be of the insulated wire
