System Options
To change these settings, choose System Options from the Main Menu.
• Language sets the micro-terminal language.
• Signal
sets units of distance and speed to the appropriate country (USA or Canada - CND).
• Red manual
allows the user to manually handle the system with no regard for programmed
Red clearance time. When the option is disabled (set to “No”), Red clearance time is
automatically added between opposing greens when manually handling.
• Timeout
refers to the amount of time the controller will tolerate a break in radio
communication. Note that the higher this number is, the longer it will take the system to fail
in the event of a communication loss. The default Horizon value is 5.0 seconds
• Quartz Sub
is an option that allows the system to continue operating once radio
communication has been lost. If communication is broken for longer than the Timeout
value, the controller can revert to Quartz mode to continue operating. By default, this
option is set to “Disabled.” There are four other options to choose from in the event of lost
communication:
• Enabled - Normal operation during green intervals, although extension times are
disregarded.
• Error - Instead of a green indication, the programmed Error mode is displayed during
green intervals.
• Preset - Uses the Quartz Substitution setting selected during programming.
• Lamps Off - Instead of a green indication, lamps go dark during green intervals.
When the system is running in Quartz Substitution mode, extended green times will be
disabled due to the loss of communication. All green times will equal the base green time
plus half the extension time. If communication is reestablished, the program will run as
normal. Once activated, the system will run a minimum of 2 cycles before returning to radio
mode (once communication has ben re-established).
• Error is the mode that this particular controller will enter in the even of a failure when
running a program. Flash Red, Flash Yellow, Solid Red, and Lamp Off are available. Flash
Red is the default setting.
• Flash
is the indication that will be displayed when the user manually activates Flash Mode
via the micro-terminal when running a program. Flash Red is the default. NOTE: Using
SPECIAL programming, each phase can be set to a different Flash Mode to allow main traffic
to flow while side streets must stop.
• Password
By setting a password,the user can lock the active program, allowing edits to
be made only after the correct password has been entered. If the password is forgotten,
please contact Horizon Signal at 800-852-8796.
NOTE: If any of these settings are changed, they will not take effect until a new program is loaded.
