SIGNAL GROUP OPERATION
Signal Group 5 – Partially Controlled Right Turn (Red Arrow Drop Off Operation)
In order to allow SG5 to operate as a partially controlled turn, the following occurs:
SG5 operates Green/Yellow/Red in CØ and can be switched to blank in AØ.
If there is no P1 demand in AØ, SG5 red will be switched off at the end of AØ late start period.
If P1 runs in AØ, SG5 is held red in AØ for the duration of Timer 1 (which starts timing at the start of P1 walk using Special purpose Timesetting No. 9).  When Timer 1 expires, SG5 red is switched off in AØ if it is later than AØ late start period.
AØ ECO is used to guarantee SG5 minimum blank period in AØ. Timer 2 (Special Purpose Timesetting No.10) starts timing at the beginning of SG5 blank period. When Timer 2 expires, expire AØ ECO period.
SG5 red will remain red in CØ if SG5 gaps.
SG5 goes red at the start of SG2 red in AØ.
SG5 is held red in BØ.
