Operations Manual

2.4.2.1 EXTEND ALWAYS (DEFAULT)

Call Extend time starts counting down when the last vehicle clears the loop detection zone.

During the Extend time the DET indicator will flash four times per second and the

DEFLECTOMETER will display the letter "E". Any vehicle entering the loop detection zone

during the Extend time period causes the Extend timer to be reset and the output

maintained. The Timer Control input has no effect on this mode.

Call Extend time starts counting down when the last vehicle clears the loop detection zone

if the Timer Control input is True (low). During the Extend time the DET indicator will flash

four times per second and the DEFLECTOMETER will display the letter "E". Any vehicle

entering the loop detection zone during the Extend time period causes the Extend timer to

be reset and the output maintained.

The Extend on Green mode is enabled by a factory installed jumper located at E6 on the

pcb. Consult the factory for details.

Timer Control inputs are provided for each channel to modify the operation of the Delay

and Extend Timing functions. The application of a True (low) state voltage will inhibit the

Delay timing function and/or enable the Extend timing function as described in sections

2.4.1 and 2.4.2.2. When the Timer Control Input is True (low) the decimal point of the

channel DEFLECTOMETER display will illuminate.

Timer Control inputs are primarily provided for downward compatibility.

If a channel is not to be used, it may be switched off (disabled) by setting the Operational

Mode to OFF. See section 2.2.6.

Press the MODE and FREQ buttons simultaneously to reset the channel. This will clear any

previous loop fault indication and cause the channel to retune.

Press the Channel 1 MODE and FREQ buttons simultaneously while first applying power to

the unit to reset all channels to the factory default settings.

The LMD Series Loop Monitor continuously checks the integrity of the loop. The system is

able to detect open circuit loops, shorted loops, or sudden changes in inductance

exceeding 25% of the nominal inductance.
