GENERAL NOTES
SUMMARY OF XSF FLAGS
XSF1 - For auto-introduction of P1.
XSF2 - For auto-introduction of P2.
XSF3 - For auto-introduction of P3.
XSF4 - For auto-introduction of P4.
XSF5 - Allows late introduction of P1 in AØ (Masterlink only).
XSF6 - Allows late introduction of P2 in AØ (masterlink only).
XSF7  - Allows detector 13 to place non-locking calls for CØ and inhibit detector 19 to place non-locking for CØ.
XSF8 - Allows detector 13 to extend CØ and inhibit detector 19 to extend CØ.
SUMMARY OF MSS FLAGS
MSS1  - Set for the duration of Detector 13 being alarmed.
MSS2 - Set for the duration of Detector 19 being alarmed.
GENERAL OPERATION
Clear vehicle demands during associated phase green and yellow.
Use AØ Yellow for EØ Yellow when transitioning from EØ->BØ or EØ->CØ or EØ->DØ.
Use EØ Yellow for BØ Yellow when transitioning from BØ->AØ.
Use BØ special all red when transitioning from BØ->EØ or BØ->AØ.
Use EØ special all red when transitioning from EØ->DØ.
SIGNAL GROUP OPERATION
Signal Group 7
Late Start SG7 in BØ if transitioning from DØ->BØ.
Signal Group 8
Late Start SG8 in EØ if transitioning from DØ->EØ.
SG8 introduces at the start of EØ if transitioning from AØ->EØ or BØ->EØ.
Signal Group 14 – Partially Controlled Right Turn (Red Arrow Drop Off Operation)
SG14 operates Green/Yellow/Red in CØ and can be switched to blank in DØ.
If there is no P3 demand in DØ, SG14 red will be switched off at the end of DØ late start period.
If P3 runs in DØ, SG14 is held red in DØ for the duration of Timer 1 (which starts timing at the start of P3 Walk using Special Purpose Timesetting No. 9). When Timer 1 expires, SG14 red is switched off in DØ if it is later than DØ late start period.
DØ ECO is used to guarantee SG14 minimum blank period in DØ. Timer 2 (Special Purpose Timesetting No. 10) starts timing at the beginning of SG14 blank period. When Timer 2 expires, expire DØ ECO period.
SG14 goes red at the start of SG4 red in DØ.
SG14 is held red in AØ, BØ & EØ.
PEDESTRIAN GROUP OPERATION
Pedestrian 1
P1 demands AØ.
P1 can introduce at the start of AØ.
P1 can clearance overlap from AØ->BØ.
P1 can introduce at any time in AØ if XSF5 is set (Masterlink only).
P1 auto introduces at the start of SG1 if XSF1 is set (all modes).
Pedestrian 2
P2 demands AØ.
P2 can introduce at any time in EØ & at the start of AØ and can overlap EØ->AØ.
P2 can introduce at any time in AØ if XSF6 is set (Masterlink only).
P2 auto introduces at the start of SG2 if XSF2 is set (all modes).
Pedestrian 3
P3 demands DØ.
P3 can introduce at the start of DØ.
P3 auto introduces at the start of DØ if XSF3 is set (all modes).
Pedestrian 4
P4 demands DØ.
P4 can introduce at any time in CØ & at the start of DØ and can overlap CØ->DØ.
P4 auto introduces at the start of SG4 if XSF4 is set (all modes).
DETECTOR OPERATION
Detector 13
·         Detector 13 places locking calls for DØ.
·         Detector 13 places non-locking calls for CØ when its presence time expires if XSF7 is set.
·         Detector 13 extends CØ if XSF8 is set.
·         If Detector 13 is alarmed, it will be ignored (i.e. not to call CØ and not to extend CØ). Set MSS1 for the whole duration when Detector 13 is alarmed.
Detector 19
·         Detector 19 places non-locking calls for CØ when its presence time expires (no XSF7 set).
·         Detector 19 extends CØ (no XSF8 set).
·         Inhibit Detector 19 from demanding CØ if XSF7 is set.
·         Inhibit Detector 19 from extending CØ if XSF8 is set.
·         If Detector 19 is alarmed, it will be ignored (i.e. not to call CØ and not to extend CØ). Set MSS2 for the whole duration when Detector 19 is alarmed.
