| OPERATION OF AUDIO TACTILE UNITS (WAIT STATE 6 & SPECIAL OUTPUT) | ||||||||||||||||||||||||
| Wait State 6 (WS6) and Special Output 3 (SO3) inhibits the operation of audio tactile units: | ||||||||||||||||||||||||
| · The audio tactile units are normally to be activated at all times under DDA. | ||||||||||||||||||||||||
| · Under certain circumstances with approval of Manager, the audio tactile units can be inhibited from operation with the activation of XSF3. | ||||||||||||||||||||||||
| OPERATION OF ADVANCED WARNING SIGNS (via WS7 / SO2 and WS8 /SO1 Outputs) | ||||||||||||||||||||||||
| Wait State 7 (WS7) / Special Output 2 (SO2) and Wait State 8 (WS8) / Special Output 1 (SO1) control the operation of two flashing “PREPARE TO STOP” signs: | ||||||||||||||||||||||||
| · Wait State 7 (WS7) or Special Output 2 (SO2) controls the operation of the sign on the southern approach. | ||||||||||||||||||||||||
| · Wait State 8 (WS8) or Special Output 1 (SO1) controls the operation of the sign on the northern approach. | ||||||||||||||||||||||||
| Wait State 7 (WS7) and Special Output 2 (SO2) are switched on at the start of AØ ECO when transitioning from AØ → BØ, AØ → CØ, AØ → D1Ø or AØ → D3Ø. | ||||||||||||||||||||||||
| Wait State 7 and Special Output 2 will remain on until SG1 goes green in AØ or D2Ø. | ||||||||||||||||||||||||
| Wait State 8 (WS8) and Special Output 1(SO1) are switched on when Timer “X” (Refer Special Purpose Timesetting No. 11) has expired. Timer “X” starts timing at the start of AØ ECO when going AØ → BØ, AØ → CØ, AØ → D1Ø or AØ → D2Ø. | ||||||||||||||||||||||||
