If a real phase is deleted, then the signals will remain at red (or blackout in the case of

a green arrow phase) whenever a stage that the phase normally appears in is active.

If a dummy phase is deleted, then any effect its appearance has on stage changes or

timings will be cancelled.

When a stage is deleted, any demands for that stage or for phases within the stage must

also be deleted by the same timetable setting, unless the phases appear in other stages.

In order to delete current demands and prevent further demands, it is recommended

that such demands be deleted by using special conditioning to write a “FALSE” state

to the entry in the latched or unlatched demand arrays for the appropriate phase/stage.

When a phase is deleted, any demands for that phase must also be dependent on the

same timetable setting.

If the above two conditions are not met, then outstanding demands for stages or

phases may never be satisfied.

The deletion of stages or phases is effective in all modes except Hurry Call and Fixed

Time mode, as deletion of phase/stages associated with these later two modes would

cause the controller to lock up.

If you wish to delete a phase or a stage and a form of fixed time working is required,

then “Fixed time to Current Maximums” can be used. This uses the VA mode with

permanent demands and extension. Thus if a phase/stage is to be deleted then provided

demands for it are also deleted, it can be deleted without problems.

(e) Switch To/From Part-Time Mode

Part-time mode may be switched to and from by a timetable setting. See section 9.2 for

a more detailed explanation.

(f) Switch A Conditioning Flag Active/Inactive

A conditioning flag that is required to indicate a particular time of day may be switched

active or inactive by a timetable setting.

(g) Switched DFM

DFM can be switched between four different Timesets as required. The Monitor times

can be adjusted by the Handset.
