PHASING DIAGRAM |
| OPERATION IN LINK MODE |
| 1. Signal groups are independent of phasing. All phases have a permanent demand in Masterlink & Flexilink |
| 2. SG1 & SG2 cannot close down during A (refer note 6 below for the exception). |
* | 3. SG1 & SG2 can close down at any time during B green, provided SG1 & SG2 minimum green has expired and both approaches |
| gap or waste. If SG1 & SG2 close down at the end of B green (i.e. at the start of B yellow), P1 introduces at the start of C |
* | 4. SG1 & SG2 cannot close down during C |
| 5. Any ped demand placed during B intergreen or during C will not be serviced until the next cycle. |
| 6. If B is left out of the sequence in Masterlink or Flexilink, SG1 & SG2 can close down at the start of A yellow and P1 introduces at |
| the start of C. |
| 7. The operation of D, E, F are the same as for A, B, C respectively. D, E and F 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 A and C. |
| 2. A is extended by the vehicle detectors. When A gaps or wastes, A and SG1 & SG2 close down together. |
| 3. C is called by P1. P1 introduces at the start of C (SG1 & SG2 close down at the start of A yellow). C runs for the duration of |
| P1 walk, clearance and solid don't walk time. |
