Loop Installation Guide 1. The detector should be installed in a waterproof housing as close to the loop as possible. 2. The loop and feeder should be made from insulated copper wire with a minimum cross-sectional area of  1.5mm2 . The feeder should be twisted with at least 20 turns per metre. Joints in the wire are not  recommended and must be soldered and made waterproof. Faulty joints could lead to incorrect operation of  the detector. Feeders which may pick up electrical noise should use screened cable, with the screen earthed  at the detector. 3. The loop should be either square or rectangular in shape with a minimum distance of 1 metre between  opposite sides. Normally 3 turns of wire are used in the loop. Large loops with a circumference of greater than  10 metres should use 2 turns while small loops with a circumference of less than 6 metres should use 4 turns.  When two loops are used in close proximity to each other it is recommended that 3 tu

Compact Size: the compact and well engineered housing Combines all of the industry requirements regarding features and functionality and allows this detector to be Incorporated into any or existing traffic detection system. Diagnostic Capabilities : Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.  Selectable Presence Time: The output of the presence Relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop  Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.  Two separate output relays: Presence Relay A is presence output. Can be extended for 0,2,5,8,10,15,20 or 30 seconds, programmable with external 10 way DIP switches. Pulse Relay B, programmable with external 10 way DIP switches, provides presence, pulse on entry, pulse on exit, or fail
