GENERAL NOTES
START UP
At START UP the controller goes immediately to BØ and extends BØ to maximum
GENERAL NOTES
1. Controller can rest in either BØ or DØ.
2. Phase Change Priority
For each phase, the following table describes the priority order for servicing any demanded phases:
     
CURRENT PHASE PRIORITY COMMENTS
     
1. BØ  Unconditional (i.e. Controller must go to BØ after AØ)
     
1. CTO Phase Controller will go BØ®CTO Phase immediately, provided BØ minimum has expired
     
  2. CØ If the controller is going BØ®CØ then BØ must extend to at least the maximum extension green
     
  3. AØ Controller will go BØ®AØ immediately, provided BØ minimum has expired
     
1. DØ Unconditional (i.e. Controller must go to DØ after CØ)
     
1. CTO Phase Controller will go DØ®CTO Phase immediately, provided DØ minimum has expired
     
  2. AØ If the controller is going DØ®AØ then DØ must extend to at least the maximum extension green
     
  3. CØ Controller will go DØ®CØ immediately, provided DØ minimum has expired
     
CTO Phase AØ or CØ (Dependent on previous operating phase before CTO phase) ·         If the previous phase (before going to the CTO phase) was BØ, then the controller must go to CØ.
    ·         If the previous phase (before going to the CTO phase) was DØ, then the controller must go to AØ.
