DISPLAYS AND KEYBOARD
The LMD display operates in a true menu format
whereby the display lists, in English, various categories
from which the user may select. The base menu lists
the most general category choices such program mode
and run mode data. From this base menu, when a
category is selected, a sub-menu appears listing further
choices such as security code, controller, coordination,
time clock, pre-emption, etc. Each sub-menu further
breaks down the choices into more specific categories
until the specific sections of data can be obtained. The
display operates such that a user familiar with traffic
terminology, but unfamiliar with the display can
successfully operate the display by following menu
selections.
Context sensitive help screens are provided, giving a
description of the functions on each screen.
SECURITY CODE
An optional security code can be programmed, which
when activated, allows data changes. The code auto-
matically deactivates 10 minutes after the last user key-
stroke. With knowledge of the old security code, the se-
curity code can be changed or inhibited. The security
code can be keyboard disabled (no code required for
data entry).
RUN MODE INDICATIONS
The run or observation mode is used to display opera-
tional status of the unit. The LMD displays the following
information upon user request:
Basic Timing Display
•
Indicates G,Y,R,W, DW, TØN, Veh and Ped Act per
phase
•
Indicates G,Y,R per each overlap
•
Indicates service plan in effect (0= none)
•
Indicates current timing per ring of min gm, psg, max I/ll,
max plan timing, walk, don’t walk, yellow, red
•
Indicates if phase Is extending, has recall, or CNA
•
Indicates termination mode: force off, max, gap-out
•
Indicates if phase is in red or green rest state
•
Indicates if phase is in conditional service or SGO
mode
•
Indicates if phase has hold applied, If ring has Inhibit
max applied, or if unit has stop time or MCE applied
•
Indicates if Gap is reducing, or variable initial is in
effect
• Indicates Current timing of active cycle and offset
• Indicates active pre-empt
• Indicates active Transit Priority, TP phases and
special timings
Coordination Timing Display
• Indicates local/master cycle and offset timers
• Indicates status of force offs and permissives 1-8
• Indicates Ped Permissive and Coord Hold Status
• Indicates, if TBC mode, current time of day
Coordination Mode Status Display
•
Indicates active and selection mode of timing plan
and C/S/O.
• Indicates coordination sync status, In or not in sync
•
Indicates the cycle and offset in effect and their
values
•
Indicates the sync reference mode (if applicable)
• Indicates if unit is in system or free and why (in
English).
