| GENERAL OPERATION | ||||||||||||||||||||||||||||
| REVn. – first scan after start-up demands BØ. | ||||||||||||||||||||||||||||
| PHASE OPERATION | ||||||||||||||||||||||||||||
| Substitute AØ Yellow for CØ Yellow when transitioning CØ -> BØ. | ||||||||||||||||||||||||||||
| DETECTOR OPERATION | ||||||||||||||||||||||||||||
| Detector 6 | ||||||||||||||||||||||||||||
| Detector 6 places immediate locking calls for AØ and places non-locking calls for CØ when its presence time expires. | ||||||||||||||||||||||||||||
| Detector 8 | ||||||||||||||||||||||||||||
| Detector 8 places locking calls for CØ. | ||||||||||||||||||||||||||||
| Clear calls for CØ from Detector 8 during Signal Group 3 green and yellow and during Signal Group 6 green and yellow. | ||||||||||||||||||||||||||||
| In AØ, if BØ is demanded (via Pedestrian 2 and/or Detectors 7 & 9), then clear demand for CØ from Detector 8. | ||||||||||||||||||||||||||||
| SIGNAL GROUP OPERATION | ||||||||||||||||||||||||||||
| Signal Group 4 | ||||||||||||||||||||||||||||
| Signal Group 4 is a 3-aspect (green / yellow / red) partially controlled right turn (conditional red) at all times. | ||||||||||||||||||||||||||||
| Signal Group 4 operates green / yellow / red in CØ and is switched to “blank” during AØ as described below. | ||||||||||||||||||||||||||||
| Signal Group 4 red will be switched to blank at the end of AØ Late Start period if Pedestrian 1 is not operating. | ||||||||||||||||||||||||||||
| If Pedestrian 1 does operate in AØ, Signal Group 4 is held red in AØ while Timer 1 is timing. Timer 1 starts timing at the start of Pedestrian 1 Walk using Special Purpose Timesetting No. 9. When Timer 1 expires, Signal Group 4 red will be switched to blank. | ||||||||||||||||||||||||||||
| The value of AØ Early Cut Off is used to guarantee a minimum blank period for Signal Group 4 in AØ. Timer 2 starts timing at the start of Signal Group 4’s blank period using Special Purpose Timesetting No. 10. When Timer 2 expires, AØ Early Cut Off will be expired. | ||||||||||||||||||||||||||||
| ** Do not alter one of AØ ECO or Special Purpose Timesetting No.10 without regard for the other. | ||||||||||||||||||||||||||||
| If going from AØ to BØ, Signal Group 4 will be switched to red at the start of Signal Group 2 Red (AØ Red) and will be held red throughout BØ. | ||||||||||||||||||||||||||||
| If going from AØ to CØ, Signal Group 4 will remain blank during AØ Red before turning green in CØ. | ||||||||||||||||||||||||||||
| Signal Group 5 | ||||||||||||||||||||||||||||
| Late start SG5 in BØ when transitioning from AØ -> BØ. | ||||||||||||||||||||||||||||
| SG5 introduces at the start of BØ if transitioning from CØ -> BØ. | ||||||||||||||||||||||||||||
| PEDESTRIAN GROUP OPERATION | ||||||||||||||||||||||||||||
| Pedestrian 1 | ||||||||||||||||||||||||||||
| P1 demands AØ. | ||||||||||||||||||||||||||||
| P1 introduces at the start of AØ. | ||||||||||||||||||||||||||||
| P1 auto introduces at the start of AØ if XSF 1 is set. | ||||||||||||||||||||||||||||
| P1 cannot reintroduce if demanded when resting in AØ – instead place a call for BØ to service P1 at the next start of AØ. | ||||||||||||||||||||||||||||
| Pedestrian 2 | ||||||||||||||||||||||||||||
| P2 demands BØ. | ||||||||||||||||||||||||||||
| P2 introduces at the start of BØ. | ||||||||||||||||||||||||||||
