when a vehicle is NOT over the roadway loop. The Sensitivity Level will be now displayed
on the DEFLECTOMETER. Pressing the SENS or SENS button once will display the
Sensitivity Level without changing the setting. After pressing the SENS or SENS
buttons to display the Sensitivity Level, the setting can then be modified by pressing the
SENS or SENS buttons again. The display will automatically return to the normal
display after three seconds. The factory default Sensitivity Level is 6.

Note that each change of the Sensitivity Level while in this "direct adjust" mode causes the
LMD Series to retune.
2.1.3 DYNAMIC DEFLECTOMETER DISPLAY OPERATION
While the LMD Series is in the Call state (DEFLECTOMETER = 1-9), the
DEFLECTOMETER displays the Call Strength (1 – 9). When the Call terminates (DET
indicator Off) the Call Strength will be displayed for an additional three seconds. Pressing
the SENS or SENS button during this interval will modify the Sensitivity Level as
described in section 2.1.1, with the DEFLECTOMETER display remaining in the Call
Strength mode.
Pressing the SENS or SENS button when the LMD Series is not in the Call state
(DEFLECTOMETER = 0) will display and modify the Sensitivity Level directly as described
in section 2.1.2. In this case the DEFLECTOMETER displays the actual Sensitivity Level.
2.2 SET THE OPERATIONAL MODE
Operational mode can be set to Short Presence, Long Presence, Pulse, Call or Off mode.
Pressing the MODE button once will display the Operational Mode without changing the
setting. After pressing the MODE button to display the current Operational Mode, the
setting can then be changed by pressing the MODE button again. The display will
automatically return to the normal display after several seconds.
Setting a new Operational Mode will cause the channel to retune.
2.2.1 OUTPUT CALL TEST
When the MODE button is pressed and held for one second, the unit will generate a pulsed
(125 ms) Call state (true) output every 1500 ms. This operation can be used to quickly
verify that a Call output is being received by the Controller Unit.
2.2.2 SHORT PRESENCE MODE (S)
The Short Presence mode will tune out a continuous Call after 30 minutes. Use Short
Presence unless the detection zone is expected to be continuously occupied for periods of
time in excess of 30 minutes.
2.2.3 LONG PRESENCE MODE (L)
The Long Presence mode will tune out a continuous Call after 120 minutes.
2.2.4 PULSE MODE (P)
The Pulse mode will provide a 125 ms ± 25ms width output pulse for each vehicle entering
the loop.
