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 BØ and is switched to “blank” during CØ as described below.
SG5 red will be switched to blank at the end of CØ Late Start period if Pedestrian 3 is not operating.
If Pedestrian 3 does operate in AØ, SG5 is held red in AØ while Timer 1 is timing. Timer 1 starts timing at the start of Pedestrian 3 Walk using Special Purpose Timesetting No. 11. 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 CØ. Timer 2 starts timing at the start of SG5’s blank period using Special Purpose Timesetting No. 12. When Timer 2 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.
If going from CØ to AØ, SG5 will be switched to red at the start of SG4 Red (CØ Red) and will be held red throughout AØ.
