FST error and warning parameters
The error parameters are automatically set during auto calibration but can be manually adjusted
through ValConnect or the display.
For the full stroke the error parameters are set to the following values:
•
Breakaway timeout = Reference breakaway time + Reference FST time
•
FST timeout = Reference total time
•
Total timeout = 2 * Reference total time
•
Minimum breakaway pressure = Reference pressure at 50%
The Start pressure error limits are not set automatically and function is disabled.
The full stroke warning parameters are set to the following values:
•
Low breakaway time = Reference breakaway time – 50%
•
High breakaway time = Reference breakaway time + 50%
•
Low breakaway pressure = Reference breakaway pressure – 50%
•
High breakaway pressure = Reference breakaway pr 50%
•
Low fail position stroke time = Reference fail position stroke time – 50%
•
High fail position stroke time = Reference fail position stroke time + 50%
