| |
inputs. |
|

NOTES ON OPERATION |
|
|
|
| |
|
|
|
|
|
| A.
PEDESTRIAN DEMAND |
|
|
|
| |
|
|
|
|
| |
A demand for a
pedestrian movement is placed by an activation of a PUSH BUTTON detector
input. |
|
| |
|
|
|
|
| |
ABNORMAL OPERATION |
|
|
|
|
|
| |
|
|
|
|
| |
If a push button is
continuously stuck on, then a permanent demand for the pedestrian movement
will be placed. |
| |
When the controller is
on line to SCATS and the push button is continuously ON for the periods as
specified by |
| |
the SCATS TDA message,
then a Detector Alarm (DA) will be generated on the push button. |
|
|
|
| |
|
|
|
|
| |
If the push button is
continuously OFF, then a pedestrian demand is not placed. |
|
|
|
| |
|
|
| B.
WALK EXTENSION FUNCTION USING CLEARANCE ZONE DETECTORS |
|
| |
| |
GENERAL |
|
| |
| |
The
walk display for each pedestrian movement runs for a minimum time. These
minimum times are specified in |
| |
Special
Purpose Timesetting No. 28 for P1 and Special
Purpose Timesetting No. 32 for P2. Activation of the |
|
|
| |
CLEARANCE ZONE detectors (i.e. 9 and/or 10 for P1 or detectors 11 and/or
12 for P2) provide extension |
|
|
| |
of
the walk display up to a maximum time. The maximum
times for P1 and P2 are specified in P1 and P2 |
|
|
| |
Walk Times. |
|
|
|
| |
|
|
|
| |
Between
the minimum and maximum times as specified above, the walk display for each
pedestrian movement is |
| |
terminated if the
CLEARANCE ZONE detectors have been vacated for the period as specified in
Special |
| |
Purpose Timesetting No.
26. (Note: Generally set to 1 s). |
|
| |
|
|
| |
ABNORMAL OPERATION |
|
|
| |
|
|
| |
If the CLEARANCE ZONE detectors (i.e. 9 and/or 10 or 11 and/or 12) do
not toggle ON during the Walk |
|
|
|
|
|
|
|
| |
interval
up to the "STANDARD" walk, then terminate at this instant. The
"STANDARD" walk for P1 is |
|
| |
specified
as the total of Special Purpose Timesetting No. 28 plus Special Purpose
Timesetting No. 29, while the |
| |
STANDARD"
walk for P2 is specified as the total of Special Purpose Timesetting No. 32
plus Special Purpose |
| |
Timesetting No 33. |
|
|
|
| |
|
|
| |
Note: When the
controller is online to SCATS and a CLEARANCE ZONE
detector does not toggle ON for |
| |
the
period as specified by the SCATS TDA message, then a Detector Alarm (DA) will
be generated on that |
| |
CLEARANCE ZONE detector |
|
| |
| |
If
a CLEARANCE ZONE detector does not toggle OFF during the Walk, then extend to
maximum (i.e. the |
| |
relevant Walk Time).
This may be due to a faulty detector, or a large number of pedestrians. |
|
| |
| |
Note: When the
controller is on line to SCATS and a CLEARANCE ZONE
detector does not toggle OFF |
|
| |
for the period as
specified by the SCATS TDA message, then a Detector Alarm (DA) will be
generated on that |
| |
CLEARANCE ZONE detector.
If this occurs then the associated Walk will terminate at the
"STANDARD" |
| |
walk time. |
