GENERAL OPERATION
1. Use CØ yellow for BØ yellow if going B2Ø®DØ or AØ or B3Ø®DØ or AØ.
SIGNAL GROUP OPERATION
Signal Group 5
1. SG5 is controlled by Special Movement Timesetting no. 1 in DØ.
    DØ All Red timesetting is substituted for Special Movement Timesetting no. 1.
2. XSF5 is used to set the maximum extension green time for SG5 in DØ.
    This time is stored in Special Purpose Timesetting no. 9.
    SG5 is forced off after this maximum extension green time.
Signal Group 6
1. SG6 is controlled by Special Movement Timesetting no. 2 in DØ.
    DØ All Red timesetting is substituted for Special Movement Timesetting no. 2.
2. XSF6 is used to set the maximum extension green time for SG6 in DØ.
    This time is stored in Special Purpose Timesetting no. 10.
    SG6 is forced off after this maximum extension green time.
Signal Group 7
1. SG7 is controlled by Special Movement Timesetting no. 3 in BØ.
    BØ All Red timesetting is substituted for Special Movement Timesetting no. 3.
2. XSF7 is used to set the maximum extension green time for SG7 in BØ.
    This time is stored in Special Purpose Timesetting no. 11.
    SG7 is forced off after this maximum extension green time.
Signal Group 8
1. SG8 is controlled by Special Movement Timesetting no. 4 in BØ.
    BØ All Red timesetting is substituted for Special Movement Timesetting no. 4.
2. XSF8 is used to set the maximum extension green time for SG8 in BØ.
    This time is stored in Special Purpose Timesetting no. 12.
    SG8 is forced off after this maximum extension green time.
PEDESTRIAN GROUP OPERATION
Pedestrian 1
P1 calls AØ.
P1 can introduce at anytime in D2Ø and at the start of AØ and can overlap D2Ø®
Pedestrian 2
P2 calls AØ.
P2 can introduce at anytime in D3Ø and at the start of AØ and can overlap D3Ø®
Pedestrian 3
P3 calls CØ.
P3 can introduce at anytime in B2Ø and at the start of CØ and can overlap B2Ø®
Pedestrian 4
P4 calls CØ.
P4 can introduce at anytime in B3Ø and at the start of CØ and can overlap B3Ø®
DETECTOR OPERATION
General
Clear vehicle demands during associated phase green and yellow.
Detector 4
Clear demands for DØ from detector 4 during SG5 green and yellow.
Detector 8
Clear demands for DØ from detector 8 during SG6 green and yellow.
Detector 10
Clear demands for BØ from detector 10 during SG7 green and yellow.
Detector 12
Clear demands for BØ from detector 12 during SG8 green and yellow.
AUDIO TACTILE OPERATION
Relay Output 1 drives the audio tactile units for the pedestrian push buttons (detectors 13 - 16).
The audio tactile units are activated at 06:00 and remain on until 21:00, Monday to Sunday.
Relay Output 1 is activated by P5 Wait State (ATSC4/PSC2000) or by Special Output 1 (Eclipse).  Both P5 Wait State (P5WS) and Special Output 1 (SO1) are set in the controller personality.
If OFF-LINE
- clear XSF4, then
- if time > 06:00, set P5WS/SO1.
- if time > 21:00, clear P5WS/SO1.
If ON-LINE
- clear conditions from hardware clock, then
- if XSF4 is set, set P5WS/SO1.
