1.1 DESCRIPTION
The LMD622 two channel and LMD624 four channel Nema TS-2 rack mounted inductive
Loop Monitor with DEFLECTOMETER
double-sided 44 pin edge connectors for connection of power, loop inputs and call outputs.
The units meet or exceed all requirements for a Type A, B, C and Type D detectors as
defined in Nema Standard TS2-2003 V02.06. Each channel has individual controls for
setting up sensitivity, operational mode and frequency on the front panel. Two high intensity
front panel LEDs indicate vehicle detection, timing operation and fault monitoring status for
each channel. Call outputs are available in either relay or optically-isolated solid-state
transistor form.

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.
The DEFLECTOMETER
while a vehicle is in the detection zone. This provides feedback that the
unit is optimally tuned to detect vehicles of all sizes.
Setting the sensitivity level of the detector can be easily done in one step

is changed. See section 2.1.1.
The simple push-button interface is intuitive and eliminates many of the
reliability problems found with tiny DIP switches of conventional detectors.
Operational mode, Frequency, and Sensitivity are all programmed and
displayed using the push-button interface. Settings are stored in non-
volatile memory.
