Select the action following a power failure and a digital signal to stop and
start the F0 value calculation:
Stop/Go recovery
Last
– On power recovery, the F0 value calculation continues in the
same state as before the failure, i.e. stopped or running.
Stop – F0 value calculation stops.
Go
– F0 value calculation continues from the last recorded value.
Stop/Go source
Select a signal source to stop and start the F0 value calculation; refer to
Appendix A, page 146 for a description of the available sources.
Note.
This signal is edge-triggered. A rising edge (inactive to active) starts
the calculation. A falling edge (active to inactive) stops the calculation.
Select a 'Reset source' signal (see Appendix A, page 146) – an
edge-triggered signal to reset the calculation on a rising edge.
Default values for the target temperature, Z factor and time (D) value are
entered but can be changed.
Set the 'Preset count' value – the value the F0 value calculation counts
from and the value applied when the F0 count is reset.
Set the 'Predetermined count' value – the value at which the F0 count
stops or wraps.
Note.
The 'Preset count' value must be lower than the 'Predetermined
count' value.
Set the required number of decimal places on the 'Predetermined
count' value.
Set the 'Intermediate count' value – the value at which a digital source is
activated. This can be used as an alarm threshold to indicate when the
'Predetermined count' value is about to be reached.
