ETECTOR ANDBOOK INSTALLATION OF TRAFFIC LOOPS AND FEEDER CABLES IN SLOTS Before the work is carried out, the tools listed in the General Principles Installation handbook (see section 1.3.1) should be available. Loop Cable and Slot Dimensions Loop slots are cut into road surfaces for the installation of the following loop cables: 998/4/70671/001 50/0.25 EPR insulated... -
Page 8: Buried Cables
ETECTOR ANDBOOK However, in the case of SDE/SA loops, the presence of an isolated heavy metal object can distort the electromagnetic effect of one of the pair of loops so that a false speed assessment is given. In these cases it is necessary to re-site the loops 1 metre away from such objects. -

Page 19: Loop Detector Settings
ETECTOR ANDBOOK 2.11 Loop Detector Settings 2.11.1 Sensitivity For normal VA purposes the detectors should be set to give bicycle detection. This requires a sensitivity setting of 0.01% or 0.02%. If the setting is too sensitive the detector will be unduly sensitive to vehicles in adjacent lanes. This is most likely where a single small loop is installed on a detector channel i.e. -

Page 44: Feeder Cable To Detector Loop Tails Using The Heatshrink Joint
ETECTOR ANDBOOK CAUTION: Certain individuals are susceptible to sensitisation and if a skin rash develops medical advice should be sought. Any resin splashes on the skin should be removes before the resin hardens. 3.2.4 Feeder Cable to Detector Loop Tails using the Heatshrink Joint The part number of the kit to be used is 667/4/15084/etc. - Page 45 ETECTOR ANDBOOK Prepare the feeder cable as detailed for the type of joints and the joint kit to be used. Cut the conductors to length ensuring that the joints will be staggered within the joint shell. The outer sheath must project at least 50 mm into the joint shell in the finished joint and no crimp joint should be closer than 75 mm to the end of the shell.
