OPERATION IN LINK MODE |
|
| |
1. Signal groups are independent of phasing.
All phases have a permanent demand in Masterlink & Flexilink |
|
| |
2. SG2 cannot close down during AØ (refer note
6 below for the exception). |
|
| * |
3. SG2 can close down at any time during BØ
green, provided SG2 minimum green has expired and both approaches |
|
| |
gap or waste. If SG2 closes down at the
end of BØ green (i.e. at the start of BØ yellow), P1 introduces at the start
of CØ |
|
| * |
4. SG2 cannot close down during CØ |
|
| |
5. Any ped demand placed during BØ intergreen
or during CØ will not be serviced until the next cycle. |
|
| |
6. If BØ is left out of the sequence in
Masterlink or Flexilink, SG2 can close down at the start of AØ yellow and P1
introduces at |
|
| |
the start of CØ. |
|
| |
7. The operation of DØ, EØ, FØ are the same as
for AØ, BØ, CØ respectively. DØ, EØ and FØ are only used when double phasing. |
|
| |
8. When XSF3 (Master & Flexi) is set, P1
uses Special Purpose Timesetting No. 9 for its walk time. |
|
| |
OPERATION IN V.A. AND
FLEXI ISOLATED MODES |
|
| |
1. Controller runs AØ and CØ. |
|
| |
2. AØ is extended by the vehicle detectors.
When AØ gaps or wastes, AØ and SG2 closes down together. |
|
| |
3. CØ is called by P1. P1 introduces at the
start of CØ (SG2 closes down at the start of AØ yellow). CØ runs for the
duration of |
|
| |
P1 walk, clearance and solid don't walk
time. |
