GENERAL NOTES
SUMMARY OF XSF FLAGS
XSF1 - Inhibit operation of P1 in BØ.
XSF2 - Allows permanent demand of P1 in DØ (For Event Use).
GENERAL OPERATION
REVn. – first scan after start-up demands CØ & DØ.
Clear vehicle demands during associated phase green and yellow.
Use AØ yellow for DØ yellow when transitioning from DØ –> CØ with SG1 green in DØ.
SG1 is conditional on P1 demand in BØ and DØ.
SIGNAL GROUP OPERATION
Signal Group 1
SG1 operation is conditional on P1 demand in BØ and DØ (i.e. P1 introduces at the start of BØ and DØ if P1 is demanded).
If XSF1 is set, SG1 continue to operate in AØ intergreen when transitioning from AØ → BØ (i.e. inhibit P1 from operating in BØ).
If XSF1 is not set and there is a demand for P1 prior to the start of AØ yellow, close down SG1 at the start of AØ yellow when transitioning AØ → BØ. Allow P1 to introduce at the start of BØ. SG1 cannot re-introduce in BØ if Z5 is set. If SG1 re-introduces at the end of 3.0 seconds ‘Don’t Walk period’ of P1 and Z5 flag not set, start Timer 1 (Special Purpose Timesetting No. 9) at the start of SG1 in BØ. BØ ECO period will guarantee SG1 minimum green in BØ. When Timer 1 expires in BØ, expire BØ ECO period.
** Do not alter one of BØ ECO or Special Purpose Timesetting No. 9 without regard for the other.
If P1 is demanded prior to start of CØ yellow, allow P1 to introduce at the start of DØ. SG1 can introduce at the end of 3.0 seconds ‘Don’t Walk period’ of P1 in DØ or at the start of AØ.
PEDESTRIAN GROUP OPERATION
Pedestrian 1
P1 calls BØ or DØ.
P1 can introduce at the start of BØ or DØ.
P1 cannot introduce in BØ if XSF1 is set.
P1 is permanently demanded in DØ if XSF2 is set.
DETECTOR OPERATION
Detector 2
Clear calls for BØ via Detector 2 during DØ green and yellow.
Clear calls for DØ via Detector 2 during BØ green and yellow.
Detector 2 extends BØ & DØ.
Detector 5 
Detector 5 is a bike detector and it places a locking call for CØ.
Detector 5 alarms when short-circuited only.
Detector 5 calls CØ only when it alarms.
Detector 6
Detector 6 places locking calls for BØ & DØ.
Detector 6 extends BØ, CØ & DØ and expaps BØ → CØ → DØ.
Clear calls for BØ via Detector 6 during DØ green and yellow.
Clear calls for DØ via Detector 6 during BØ green and yellow.
Clear calls for BØ & DØ via Detector 6 during CØ green and yellow.
Clear calls for BØ & DØ via Detector 6 if CØ is demanded (i.e. via Detector 5 or Detector 7).
