Rack Mount Loop Detectors -LM602 DUAL CHANNEL – NEMA TS-1 Type
The LM602 has been specifically designed to deal with
all traffic and highway applications and meets or exceeds all requirements of NEMA Standard TS1-1989 (R2000), Section 15 (Inductive Loop Detectors).
Rugged Handle Assembly: The rugged integrated handle assembly is made of GE Lexan™, which is a super durable polycarbonate resin. The design of this assembly strengthens
and protects the whole PCB assembly much better than conventional metal face plates. The temperature stability of critical components is improved with the larger more encompassing enclosure. Detailed operating instructions are conveniently attached directly on the side of the unit, eliminating the need for instruction cards.
Separate Detect / Fault LEDs: The Fault (FLT)
indicator displays the type of fault: Short, Open or 25% change of inductance. Each type of fault is indicated by a unique sequence of flashes allowing the user to diagnose loop failures at a glance. Individual indicators eliminate the confusion encountered with other detectors that use only one LED to display both faults and detection.
Loop Fault Memory: Loop Fault Memory reports
previous loop fault information. If a loop problem
self-heals, the detector channel will resume normal
operation. The contents of the memory will be displayed on the Fault (FLT) indicator. This feature can be used to isolate the source of intermittent loop failures.
Automatic Tuning / Loop Configuration: No manual tuning is required and works effectively on all inductive loops from 20 to 2500 micro Henries.
Fifteen (15) Levels of Sensitivity: Allows users to fine tune to their application.
Four Loop Frequencies and Sequential Scanning: Together these features greatly reduce the incidence of cross-talk.
Three Selectable Modes:
- Short Presence: For normal detection.
- Long Presence: For sites where loops may be
occupied for extended periods of time.
- Pulse: For counting and volume.
- Environmental Tracking: Ensures reliable operation by continuously adjusting for changes in ambient conditions.
Options: Relay Outputs, Model LM602R
