GENERAL NOTES
SUMMARY OF XSF FLAGS
(Communications Operation of XSF flags is required)
XSF1 - Allows the auto introduction of P1 & P2.
XSF2 - Allows the auto introduction of P3 & P4.
XSF6 - Places a permanent demand for DØ and removes the 'Recall' for AØ.
XSF7 - When set with XSF6, DØ late start, minimum green and yellow periods are expired if there are other phase demands set prior to the start of or during DØ.
SUMMARY OF mss FLAGS
MSS6 - set when XSF6 is set.
MSS7 - set when XSF6 and XSF7 are set.
General OPERATION
If in AØ clear demands for EØ.
If in CØ clear demands for BØ.
SIGNAL GROUP OPERATION
SG7 - late starts in EÆ when going CÆ ® EÆ, or DÆ ® EÆ with XSF7 set.
SG8 - late starts in BÆ when going AÆ ® BÆ, or DÆ ® BÆ with XSF7 set.
PEDESTRIAN GROUP OPERATION
P1 - calls AØ.
- can introduce at the start of AØ.
- auto introduces at the start of AØ when XSF1 is set.
P2 - calls AØ.
- can introduce at the start of AØ, and at anytime in EØ, and overlap EØ → AØ.
- auto introduces at the start of SG2 when XSF1 is set.
P3 - calls CØ.
- can introduce at the start of CØ.
- auto introduces at the start of CØ when XSF2 is set.
P4 - calls CØ.
- can introduce at the start of CØ, and at anytime in BØ, and overlap BØ → CØ.
- auto introduces at the start of SG4 when XSF2 is set.
Detector OPERATION
Det 4 - places non-locking calls for EØ when presence timer expires.
Det 8 - places non-locking calls for BØ when presence timer expires.

PHASE OPERATION
DWELL ON RED PHASE
DØ is a 'Dwell on Red' phase that operates overnight from 21:00 to 5:00 Monday to Sunday when XSF6 is set, as part of a Road Safety Department trial.
During this period, the signals rest in DØ, which has a permanent demand, and only goes to AØ, BØ, CØ or EØ if they are demanded.
DØ runs for the late start, minimum green and yellow periods.
When XSF6 is set, a permanent demand for DØ is set and the 'Recall' for AØ is removed.
When XSF6 is set MSS6 is set.
XSF6 is set by time of day (Action List).
XSF6 selects the alternate phase sequence in Flexilink.
When XSF7 is set with XSF6, DØ late start, minimum green and yellow periods are expired if there are other phase demands set prior to the start of or during DØ, except for the following transitions:
- AØ or EØ ®® AØ or EØ.
- BØ or CØ ®® BØ or CØ
When XSF6 and XSF7 are set, MSS7 is set.
