| GENERAL OPERATION | ||||||||||||||||||||||||||
| REVn. – first scan after start-up demands CØ. | ||||||||||||||||||||||||||
| Clear phase demands during associated green and yellow times. | ||||||||||||||||||||||||||
| Use AØ Special Red for AØ Red if transitioning from AØ →CØ. | ||||||||||||||||||||||||||
| Use CØ Yellow for BØ Yellow if transitioning from BØ →AØ or BØ →DØ. | ||||||||||||||||||||||||||
| Use AØ Yellow for DØ Yellow if transitioning from DØ → BØ or DØ →CØ. | ||||||||||||||||||||||||||
| If in AØ, clear demands for DØ. | ||||||||||||||||||||||||||
| If in CØ, clear demands for BØ. | ||||||||||||||||||||||||||
| SIGNAL GROUP OPERATION | ||||||||||||||||||||||||||
| Signal Group 5 | ||||||||||||||||||||||||||
| SG5 is a 3-aspect (green / yellow / red) partially controlled right turn (conditional red) at all times. | ||||||||||||||||||||||||||
| SG5 operates green / yellow / red in DØ and is switched to “blank” during AØ as described below. | ||||||||||||||||||||||||||
| SG5 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, SG5 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, SG5 red will be switched to blank. | ||||||||||||||||||||||||||
| The value of AØ Early Cut Off is used to guarantee a minimum blank period for SG5 in AØ. Timer 2 starts timing at the start of SG5’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 or CØ, SG5 will be switched to red at the start of SG2 Red (AØ Red) and will be held red throughout BØ and CØ. | ||||||||||||||||||||||||||
| Signal Group 6 | ||||||||||||||||||||||||||
| SG6 is a 3-aspect (green / yellow / red) partially controlled right turn (conditional red) at all times. | ||||||||||||||||||||||||||
| SG6 operates green / yellow / red in BØ and is switched to “blank” during CØ as described below. | ||||||||||||||||||||||||||
| SG6 red will be switched to blank at the end of CØ Late Start period if Pedestrian 4 is not operating. | ||||||||||||||||||||||||||
| If Pedestrian 4 does operate in CØ, SG6 is held red in CØ while Timer 3 is timing. Timer 3 starts timing at the start of Pedestrian 4 Walk using Special Purpose Timesetting No. 11. When Timer 3 expires, SG6 red will be switched to blank. | ||||||||||||||||||||||||||
| The value of CØ Early Cut Off is used to guarantee a minimum blank period for SG6 in CØ. Timer 4 starts timing at the start of SG6’s blank period using Special Purpose Timesetting No. 12. When Timer 4 expires, CØ Early Cut Off will be expired. | ||||||||||||||||||||||||||
| ** Do not alter one of CØ ECO or Special Purpose Timesetting No. 12 without regard for the other. | ||||||||||||||||||||||||||
