■ Premature Termination of the 'Fast-Start Function'
There are some situations where it is necessary to abort the 'Fast-Start Function'. Examples for these situations
are:
• The doors are reversing (opening again).
• A time-out occurs (e.g. the doors can't be closed because they are blocked).
• A fault occurs (e.g. motor thermistor or a leaving of the door zone).
In principle, there are two ways how the 'Fast-Start Function' can be aborted:
• Immediate termination regardless of the state of the drive controller's status bit S6 'mechanical brake'.
• Premature termination considering the state of the drive controller's status bit S6 'mechanical brake'.
Immediate Termination Regardless of S6 'Mechanical Brake' Status :
The 'Fast-Start Function' can be terminated immediately by clearing the lift controller's command byte.
Note:
A termination of the 'Fast-Start Function' regardless of the state of the drive controller's status bit S6 'mechanical brake' can cause a
drifting of the car and a disconnection of the main contactors under load. Therefore, whenever possible, termination considering the
state of the drive controller's status bit S6 'mechanical brake' should be preferred.
