3. Set the green time for Phase 1/C1 (carts 1 & 2). The first number on the screen is the
base green. This is the minimum amount of green time a given phase will allow without
detection. The second number is the extension time. The extension will only be applied
if the system is using some form of vehicle detection. If you are not using detection,
the extension will be ignored. Base green plus extension equals your maximum green
time.
When set to “Yes,” “Rest in Red” means that the given phase will only turn green in the
event of a vehicle detection. When set to “No,” the signal will cycle as normal.
“Red Extens” sets a maximum additional red clearance time extension in seconds in
case the work zone is not clear at the end of the regular “All Red” time. An extra sensor
must use the Red Clearance Extension circuit and must have “Red Extens” enabled in
the PTS Programmer’s ”System Options”.
4. Set the green time for Phase 2 (C2) (carts 3 & 4). These values can differ from those
set for Phase 1 (C1).
5. Quartz substitution allows the signal system to continue to operate following a
communications loss. It utilizes quartz clock timing for synchronization between
signals. Signals are not in communication when this mode is enabled.
*Important if Enabled make sure the “Time and Date” are set correctly in the “System
Options” before entering a program, and that the same PTS Programmer is used on all
signals in the system.*
6. Your program can be given a custom name to help identify it. Use the “Plus and
Minus” buttons to change each character and the “Arrow” buttons to move the cur-
sor. Press “E” to advance when finished.

2. The slowest anticipated vehicle speed through the work zone gets entered first,
followed by the distance of the work zone measured from stop bar to stop bar.
The PTS Programmer uses these values to calculate a recommended “All Red”
interval. This interval can still be adjusted using the “Plus and Minus” buttons.
