GENERAL NOTES
SUMMARY OF XSF FLAGS
(Communications Operation of XSF flags is required)
XSF4 - Selects Special Maximum for SG4 in Cf (Special Purpose Timesetting No. 13) (All modes).
XSF5 - Selects Special Maximum for SG5 in Cf (Special Purpose Timesetting No. 14) (All modes).
SUMMARY OF MSS FLAGS
MSS1- Set on receipt of Call, cleared by termination conditions - used to force the site to Isolated.
GENERAL OPERATION
1.      Cf ECO is used to ensure that SG1 and SG2 minimum green is provided when going CDf. Expire Cf ECO when SG1 and SG2 minimum green have expired.
2.      Use Cf ECO for SG1 and SG2 minimum green.
3.      P4 wait state drives a single aspect (w) “E” lantern during D1f green.
4.      Df can start up in D1f or D2f. Df cannot transition between sub phases.
5.      D1f has priority over D2f.
6.      Use Af yellow for Cf yellow if not going C2f → Af and not in the period 8.00am to 7.00pm Monday-Saturday.
7.      Use Af yellow for Cf yellow if not going C3f → Af and not in the period 8.00am to 7.00pm Monday-Saturday.
SIGNAL GROUP OPERATION
Signal Group 2
1.      When going AD2f, SG2 closes down in Af and reintroduces in D2f at the end of the late start.
Signal Group 4
1.      SG4 operates green-yellow-red in Cf.
2.      SG4 goes red with SG1 in Af and remains red through Bf, C3f and Df.
3.      SG4 closes down at the end of C1f or C2f green, remains red through Af late start, then goes ‘blank’ at the start of Af minimum green.
4.      If going Bf → Af, C3f → Af or Df → Af, with a demand for P1, hold SG4 red for the duration of Timer 1 (Special Purpose Timesetting No. 16). Timer 1 starts timing at the start of P1 walk. When Timer 1 expires, SG4 red is switched off.
5.      If going C1f → Af  or C2f → Af with a demand for P1, SG4 goes red at the start of Cf all red period and is held red for the duration of Timer 1 (Special Purpose Timesetting No. 16). Timer 1 starts timing at the start of P1 walk. When Timer 1 expires, SG4 red is switched off.
6.      Af ECO is used to guarantee SG4 minimum ‘blank’ period. Timer 2 (Special Purpose Timesetting No. 17) starts timing at the start of SG4 ‘blank’ period. When Timer 2 expires, expire Af ECO.
PEDESTRIAN GROUP OPERATION
Pedestrian 1
P1 calls Af.
P1 calls Bf if the controller is resting in Af.
P1 can introduce at anytime in C3f and D2f, and during Af late start, and can overlap C3Af, C3Df, DAf.
P1 closes down in Af when going AD2f. (P1 does not overlap when going AD2f)
Pedestrian 2
P2 calls Bf.
P2 can introduce at the start of Bf.
DETECTOR OPERATION
General
Clear vehicle demands during associated phase green and yellow.
Detector 3
Clear demands for CØ from detector 3 during SG4 green and yellow.
Detector 6
Detector 6 calls C1f if going ACf.
Clear demands for CØ from detector 6 during SG5 green and yellow.
OPERATION OF INTERGREEN TIMES FOR VARIABLE SPEED LIMIT SIGN (VSLS)
The intergreen times for AØ (Main Road) are varied to match the speed limit shown on the VSLS. 
The reduced speed limit for AØ is 40 km/h and operates between 08:00am and 07:00pm Mon-Sat. The speed limit outside these periods is 60 km/h.
If Monday - Saturday and time is > 08:00am
AØ uses CØ yellow (3.0 seconds)
AØ uses BØ special all red (2.5 seconds)
AØ uses CØ special all red (5.0 seconds) if going AØ®
CØ uses CØ special all red (5.0 seconds) if going CØ®
If Monday – Saturday and time is > 07:00pm
AØ uses AØ yellow (4.0 seconds)
AØ uses AØ all red (1.5 seconds)
AØ uses AØ special all red (3.0 seconds) if going AØ®
CØ uses AØ special all red (3.0 seconds) if going CØ®
OPERATION OF EMERGENCY PHASE
To assist CFA vehicles through the intersection, a Fire Station exit phase (Df) has been provided. This phase is controlled by push buttons (Det 8-10) located in the Fire Station.
Right Turn Call Function (Detector 8)
When call push button (Det 8) is activated, it calls P3 and starts a timer (refer to Special Purpose Timesetting No. 11) that when expired sets MSS1, forcing the controller to isolated operation (via VR 30), calls D1f, clears demands for Af, Bf and Cf, cancels the extension for the running phase, and terminates the running phase without violating minimum green or pedestrian times.
 
If the controller is changing phases (in the intergreen of the phase) when the CALL is received, then do not service the pedestrians in the phase which is about to run. If a pedestrian movement is in walk when the CALL is received, then select Special Purpose Timesetting No. 10 for the pedestrian walk time.
D1f automatically extends out to maximum unless a cancel push button is activated.
NOTE: Gap, headway and waste are not used in D1f.
Left Turn / Reversing Call Function (Detector 9)
When call push button (Det 9) is activated, it calls P3 and starts a timer (refer to Special Purpose Timesetting No. 15) that when expired sets MSS1, forcing the controller to isolated operation (via VR 30), calls D2f and P3, clears demands for Af, Bf and Cf, cancels the extension for the running phase, and terminates the running phase without violating minimum green or pedestrian times.
 
If the controller is changing phases (in the intergreen of the phase) when the CALL is received, then do not service the pedestrians in the phase which is about to run. If a pedestrian movement is in walk when the CALL is received, then select Special Purpose Timesetting No. 10 for the pedestrian walk time.
D2f automatically extends out to maximum unless a cancel push button is activated.
NOTE: Gap, headway and waste are not used in D2f.
Cancel Function (Detector 10)
When cancel push button (Det 10) is activated, it starts a timer (refer to Special Purpose Timesetting  No. 12) that when expired cancels the extension for Df.
Df cannot terminate until the end of Df minimum green.
The intersection will resume normal operation at the start of Af, when MSS1 is cleared.
The MSS flag can be monitored by keying in A.E004C (PSC2000) on the controller’s KDU.
Call Record Facility
The P3 demand is placed by the CALL function to enable the Call Record facility in the controller to be used, if required, to drive a display in the Fire Station. The demand for P3 is cleared at the start of Df.
The Call Record logic output can be monitored by keying in A.E004C (PSC2000) on the controller’s KDU.
DETECTOR ALARM STATUS
Detectors 8, 9 & 10 do not alarm in the OFF state.
If Detector 8 is ON continuously, D1f will not be recalled until Detector 8 changes state from OFF to ON.
If Detector 9 is ON continuously, D2f will not be recalled until Detector 9 changes state from OFF to ON.
If Detector 10 is ON continuously, the CANCEL function will operate NORMALLY, ie. Df will run for the minimum period only.
NOTE: the failure of Detector 8, 9 & 10 in the ON state will flag a detector alarm for monitoring purposes.
