EDI Web Site; www.EDItraffic.com. 1.3 DEFLECTOMETER® FEATURE The LMD Series Loop Monitor introduces a concept to the inductive loop detector field that revolutionizes the process of installing and programming a loop detector. The new user interface of the LMD Series provides the feedback necessary to the signal technician to quickly and accurately program the parameters of the detector exactly to the loop plus lead- in system characteristics. - Page 5 LMD602 and LMD604 Series Operations Manual percent of the nominal inductance. Each type of fault is signified by the fault indicator emitting a different flash sequence. This information can greatly assist the user in the diagnosis of loop related problems. The unit will detect inductance changes as small as 0.010% ∆L/L.

LMD602 and LMD604 Series Operations Manual 2.6.1 CURRENT FAULT If a fault is detected, both the DET (Red) and FLT (Yellow) LEDs continuously emit a sequence of flashes and the DEFLECTOMETER will display the letter “F”. Each type of fault is identified by a different flash sequence followed by a one second pause: Flash Sequence Fault 1 flash... -
Page 11: Section 3 Loop Installation
LMD602 and LMD604 Series Operations Manual Section 3 Loop Installation The typical sensing height is 2/3 of the shortest leg of a loop (in feet). Therefore a 4’ x 8’ loop typically has a detection height of 2.6’. The inductance of a conventional four-sided loop can be estimated using the formula: L = P x (T + T) / 4 Where L = Loop Inductance in microHenries... - Page 12 LMD602 and LMD604 Series Operations Manual circumference to prevent the loop wire from rising up while the sealant is poured and curing. Many different types of loop sealant are now available. Single part types are the easiest to apply since no mixing is required, but they also tend to be more expensive in terms of linear feet of saw slot filled.
