NTCIP Object Reference - Unit Parameters (MM->1->2->1)

NTCIP 1202 section 2.4 defines several Unit Parameters that affect the operation of the controller as a unit, rather than on a phase by phase or pattern by pattern basis.  The Unit Paramters menu (MM->1->2->1) combines NTCIP unit parameter objects with several proprietary Naztec MIB's related to the controller unit.

StartUp Flash(s) 2.4.1 STARTUP FLASH PARAMETER - The Start-up Flash parameter determines the duration (0-255 sec) that the controller remains in a flashing condition following a power interruption or enabling the Run Timer. During start-up flash, the Fault Monitor and the Controller Voltage Monitor outputs are inactive.
Red Revert 2.4.4 UNIT RED REVERT PARAMETER - The Red Revert time (0-25.5 sec) determines the minimum time for red revert on all phases.  The red revert time is the minimum amount of red indication time following a yellow interval and prior the next display of green on a the same phase. Each phase may override this parameter with an individual red revert time if it is larger than the unit red revert time (see MM->1->1->1, 2.2.2.10 PHASE RED REVERT).
Backup Time(s) 2.4.3 BACKUP TIME PARAMETER - Backup Time is the maximum amount of time, in minutes, that the controller allows before declaring its system supervisor to be offline. A system supervisor is either an on-street master controller or a central computer system. The value programmed in the Backup Time is used to reset the backup delay timer every time a communications message is received. If the backup timer ever expires without a SET to any of the system control parameters, the controller will revert to Backup Mode.
Auto Ped Clr 2.4.2 AUTOMATIC PED CLEAR PARAMETER - The Automatic Pedestrian Clear Parameter determines the behavior of the pedestrian clearance interval for the controller when manual control is enabled. When enabled (set to ON), the pedestrian clearance interval cannot be terminated prematurely by the Interval Advance input.  Set Automatic Pedestrian Clear Parameter to OFF if you want to give your law enforcement personnel the ability to terminate the ped intervals with the manual control enable and interval advance (police switch).
Phase Mode Naztec MIB - This parameter establishes the main phase operating mode of the controller. When a power-up condition occurs or the Run Timer is activated, the phase sequence and phase concurrency tables will be reprogrammed to agree with the following Phase Mode definitions.  Therefore, the Phase Mode must be set to USER if more than 8 phases or 2 rings are needed or the phase concurrency definitions are "non-standard".
  • STD8 - Standard 8 Phase

  • QSeq - Quad-Sequential

  • 8Seq - Eight-phase Sequential

  • DIAM - Texas Diamond operation
     
  • USER - User defined User-Programmable (more thaases or 2 rings)


  •  
Diamond Mode Naztec MIB - Diamond Mode determines which of the diamond operating modes is the default mode; that is, which will be active when a mode is not specifically commanded by a pattern. There are three Diamond operating modes: 1) 4 -Phase, 2) 3-Phase, and 3) Separate Intersection. Refer to the Diamond section for descriptions of these three modes.
Local Flash Start Set this entry to ON to enable the controller to automatically perform an "External Start" when the Local Flash input signal transitions from active to inactive.
Start Red Time This time is used when the controller is activated through the run timer, when power is applied or when an SDLC fault is cleared. Only when the programmed startup phases are set for RED CLR intervals, the Start Red Time value is used rather that the values programmed in the Phase timing.
Min PedClr Tm

Minimum Pedestrian Clearance Time guarantees the specified ped clearance time (in seconds) for all active phases.  This value applies to all operational modes except stop timing (police button operation).  An error message is displayed from menu MM->1->1->1 if the user attempts to enter a ped clearance time less than the Min PedClr Tim.
Allow <3 sec Yel Set this entry to ON to allow entries of less than 3.0 seconds for yellow clearance intervals. If set to OFF, entries of 0 to 2.9 seconds are not accepted.
Allow Skip Yel Naztec MIB - This feature must be enabled in order to use the OMIT YEL, YEL PHASE, phase option plus in the controller menu. 
Disable Init Ped When the controller is first activated either through an SDLC fault reset, the return of power, or upon activation of the run timer, the controller places a call on all phases and pedestrian movements. If this feature is programmed in the ON position, the pedestrian phases will not receive the initial call and therefore not be serviced.
Free Ring Seq Naztec MIB -  The default phase sequence for FREE operation is Seq # 1 (dual-ring, left-turns first sequence).  Free Ring Seq is initialized to “0” when you initialize the controller to STD8 operation.  Free Ring Seq is initialized to “0” does not override the default phase sequence for FREE operation (Seq # 1).  However, any other value (1-16) for Free Ring Sequence overrides Seq# 1 as the default phase sequence for FREE operation.
StopTm Over Prmpt Naztec MIB - The Stop-Time Over Preempt causes the stop-time inputs to have priority over preempt inputs. Use this feature to arrange priorities to be compatible with cabinet configuration and wiring. Stop Time is often wired to the output of the conflict monitor unit so that in the event of a monitor fault, the controller is halted. This aids diagnosis of why the monitor fault occurred. If preemption inputs have priority over stop-time, and a preempt input occurs, the controller will begin timing again and the diagnostic information is lost. Alternatively, if the stop time inputs may be activated from a maintenance panel switch, and a valid preempt may occur while the Stop-Time switch is active, then setting this parameter to ON is NOT recommended.

WARNING: Use care in setting this parameter. If preempts are in use and there is a Stop-Time switch on the maintenance panel, do NOT set to ON as preempt inputs may be ignored.
Invert Rail Input Naztec MIB - Invert Rail Input reverses the ground-true logic applied to all preempts defined as RAIL type preempts under Preempt Options+.
Feature Profile Naztec MIB -  This parameter allows predefined selections to be removed from the menu screens.  The default value, 0, allows all menu selections to be visible and accessed according to security definitions.  Currently, the only other value allowed is 1.  It removes selection 9, On-street Master, from the main menu screen on a Master controller.
Enable Run Naztec MIB - This is a status field showing the current setting of the Run parameter. The Run parameter must be ON for the controller to operate the signals. The Controller Voltage Monitor and Fault Monitor outputs are not asserted when the Run timer is OFF.
Display Time Naztec MIB - Enter the number of minutes (0-99) of delay following keyboard use that the controller delays before resetting the keyboard and display to its default screen, and logging-off any currently logged-in user. A user "logs in" when, if security is setup, he enters a security access code. If the Display Time is set to zero, a value of one minute is used. This provides enough time for a user to program a more reasonable time before the display is reset.
Tone Disable Naztec MIB - Set this parameter to ON to disable audible tones for keyboard operations. If set to the default value, OFF, the tone sequences that provide audible feedback will be sounded as appropriate.
TS2 Detector Faults Set this parameter to ON to allow faults reported by detector BIUs to generate detector events. Set this entry to OFF to prevent BIU generated detector faults from recording events. This parameter is useful in cases where a TS2 detector rack is not fully populated with loop detectors. In such cases, this parameter may be set to OFF, thereby preventing numerous unwanted detector events from being reported upon power-up.
SDLC Retry Time Naztec MIB - The SDLC Retry Time defines how long the SDLC port must run before its fault retry counter is reset to zero. If the SDLC Retry Time is not zero, then the controller can automatically recover from a critical SDLC fault twice before it latches the fault. Latched faults must be reset from the controller keypad (MM->8->7).

 
Max Cycle Tm Naztec MIB -  Maximum-Cycle-Time is a manual override value used to check that the controller is cycling properly.   If no value is entered, the controller will calculate a value based on the controller phase and coordination programming.  A different value is calculated for free and for coordinated operation.  Enter a value (in seconds) to override the calculated value that the controller uses to perform this check.   This feature is enabled/disabled using the Cycle Fault Action parameter and by enabling the appropriate events/alarms as described below.
CycFlt Actn Naztec MIB - A Cycle-Fault-Actn is declared when the Max Cycle Tm or the preemption seek times are exceeded.  The Cycle Fault Action (CycFltActn) setting determines whether the controller generates an ALARM or enters FLASH when the cycle fault occurs.  A cycle fault occurs only if the controller does not service valid demand within the allotted time while it is operating in a coordinated mode.  A cycle failure is declared if it is operating free.
Max Seek Trak Tim Naztec MIB -  Maximum-Seek-Track-Clearance-Time is used to check if the track phases become active as quickly as expected when a railroad preempt is received.  Enter a value at least one second greater than the maximum time it is anticpated that the controller will take to achieve track clearance.  A zero entry disables the feature.
Max Seek Dwel Tim Naztec MIB - Maximum-Seek-Preempt-Dwell-Time is used to check if the preempt dwell phases become active within the maximum expected time following the beginning of track clearance during railroad preemption or from the beginning of an emergency preempt.  Enter a value at least one second greater than the maximum time it is anticpated that the controller will take to achieve preempt dwell.  A zero entry disables the feature.
