6. EC and FCC regulationsMost electronic equipment produces some undesired interference at a close distance. To make sure the increasingnumbers of electronic equipment will not cause harmful interference, the CE (Europe) and FCC (US) regulations statevery low levels of interference that should not be exceeded. The AMB equipment does not exceed these levels.The CE regulations also state the levels of interference generated by other sources which the equipment must be able totolerate without malfunctioning. These levels are considerably higher than the interference levels produced by theelectronic equipment itself. Cellular telephones however may generate interference levels which may cause otherelectronic equipment to malfunction. AMB made sure its equipment is insensitive to the interference generated by cellulartelephones or other modern fonms of personal radio communications.The FCC regulations for Infonmation Technology equipment which must be printed in the manuals state that you musttolerate interference produced by others and you must switch-off when interference produced by your equipment isexperienced by others. The level of interference is strongly reduced when you increase the distance between two piecesof electronic equipment. For example: your portable radio will most probably experience interference when placed on topof your monitor, but will work very well a few feet away. Since the AMB transponders operate on magnetic induction theyhave no antenna, but a built-in coil instead. The transponders do not produce an electromagnetic (radio) wave but only amagnetic wave. The difference between an electromagnetic (radio) wave and a magnetic wave is that theelectromagnetic wave travels by itself over great distances and the magnetic wave does not. As the distance increasesthe strength of the magnetic wave is greatly reduced. This is why AMB transponders are no transmitters.This equipment complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) Thisequipment may not cause harmful interference, and (2) this equipment must accept any interference received, includinginterference that may cause undesired operation.Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residentialinstallation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used inaccordance with the instructions, may cause harmful interference to radio communications. However, there is noguarantee that interference will not occur in a particular installation. If this equipment does cause hanmful interference toradio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to tryto correct the interference by one or more of the following measures:.Reorient or relocate the receiving antenna..Increase the separation between the equipment and receiver-.Connect the equipment into an outlet on a circuit different from that to which the receiver is connectedEC Declaration of ConformityThe EC Declaration of Conformity is the method by which AMB i.t. declares that the AMB TranX260 system complieswith the EMC directive (89/336/EEC) and low voltage directive (73/23/EEC).The AMB active loop consists of:.AMB TranX active loopMains adapter 230 V AC/12 V DCApplicable harmonised EMC standardsEN 55022EN 50082-1Class B, Information Technology EquipmentIEC 801-2 Electrostatic DischargeIEC 801-3 Immunity to Radiated Electromagnetic FieldsIEC 801-4 Electrical Fast Transient, BurstLow voltage directiveEN 60335Authorised signatureManufacturerAMB i.t.

,~§E!!:7The AMB TranX 160 activated loop upgrade is specially designed to let anexisting AMB TranX 120/160 detection loop function normally, but function aswell as a beacon for the AMB DisplaylT.The AMB DisplaylT, which is usually fitted to the steering wheel of a kart, detectsthe signal produced by the activated detection loop while passing the loop andindicates the actual lap time on its display.Contents1.

2. Installation of the activated detection loop3 mm (1/8")'"H'"-20 mm-3/4")A-A1. Remove the existing loop wires and connection box plus the coax cable. If the coaxcable was put into a duct, use the old coax cable to pull the new coax plus 12V powercable through.2. Put the wires of the activated detection loop in the slots, with the termination box inthe spot where the 470 Ohm resistor used to be and cut the excess length of thewires. Make sure karts can not pass outside the detection loop. Extend the detectionloop outside the track if necessary.3. Put a heat shrinkage sleeve over each detection loop wire end and strip both wireends. The Soldering necessary is best done with help of a propane fired solderingiron. Solder both loop wires each to one of the two yellow wires from the new (larger)connection box now housing the connection box plus the electronics producing thebeacon signal. Slip the shrink sleeves over the solder joints and hold them over aheat source. Please make sure insulation is perfect, in order to have bestperformance over a very long period of time.4. Fill the slot with silicon. Make sure the silicon is fully under the surface of the track,otherwise the tires may pullout the silicone.5. The detection loop is sensitive to interference, possibly emitted by nearby cables.When possible keep all cables 5 m 115 ft away. Also make sure karts on other partsAMB i.t. B.V.

6. The 12V power cable may be installed alongside the coax cable leading to the AMBTranX160 decoder. The 12V adapter powering the TranX activated detection loopmay be installed permanently, but must be well protected from water and humidity.7. The activated detection loop may be powered permanently, even when the AMBTranX decoder etc. are not installed or present. In this way producing the beaconsignal continuously for any DisplaylT that may be present on the track. Powerconsumption is around 10 watts in total, depending on loop size.8. All wiring of the loop must be installed according to the drawing in order to avoid aserious degradation in performance. When joints in the loop are not soldered, thebeacon signal may, over time, when the joints become oxidised, interfere stronglywith the signals coming from passing transponders.AMB i.t. B.V. Installation Manual AMB 260- 02 5of the track will not get closer than 5 m /15 ft to the detection loop, to avoid falseinputs.

4. Operating the system I Trouble shootingInstall the existing AMB TranX 160 system as usual and according to the instructions inthe manual. When the (new) coax cable is connected to the decoder, the TranX 160system should operate as before.Now plug in the 12V adapter powering the activated detection loop. The backgroundnoise level may rise about 10 points, due to the (very low) noise level of the beacon nowoperating.When a connected sensor of an AMB DisplaylT is passed over the loop (not higher than30 cm 11 foot) the DisplaylT should indicate.The AMB TranX 160 system and the Activated loop (beacon) work fully independent ofeach other and do not interact.Beacon signal not presentCheck if the AMB mains adapter powering the activated loop is connected to the mainsand that mains voltage is present. Make sure the 12V wiring to the activated loop is notbroken or short circuited. A properly operating activator consumes between 0.3 and 0.6Amps depending of loop size.When a loop wire is broken, the AMB TranX 160 system usually still operates, althoughwith reduced received signal strength and hits, but the activating signal (beacon) is nolonger present.High background noise levelIf, after installation of the activated loop, the background noise level has increasedstrongly, disconnect the 12V adapter from the mains, in order to see if noise enters thedetection loop from the mains. Please make also sure the 12V cable leading to theactivated loop does not run alongside power and/or data cables, which may also be asource of interference.Other uses of the activated loopThe beacon signal generated for the AMB DisplaylT is identical to the signal to activatethe AM B 130 transponder which is used for rental karts. The signal produced by theAMB 130 transponder, when passing the activated loop can also be decoded by theAMB 160 decoder, so a mixed use of (personal) AMB 160 transponders and AMB 130transponders is possible.The AM B 130 transponders have the advantage that they consume only power fromtheir built-in permanent battery , when passing the activated loop, and will continue to doso for severa1100.000 passings. Accuracy, max. height and max. speed is less than forthe AMB 160 transpondersAMB i.t. B.V. Installation Manual AMB 260- 02 7
