Note:
The 'Measured data storage out
of memory' reading (Maintenance
alarm) is generated when the 'Scan
rate' is too low. After recording 100
measured values per variable, log-
ging is stopped, but the test continues
until it is completed.
After the full stroke test is canceled, the 'Sta-
tus of full stroke test' reading indicates 'Not
successful'. The reason for cancelation is
marked by the 'Maintenance alarm' mes-
sage in the Analysis of measured data fold-
er (> Current test).
Defining parameters
1. Switch to manual mode.
2. Define parameters for full stroke test. See
u Note concerning setting the FST diag-
nostic parameters on page 77.
3. Configure the cancelation conditions.
4. Select classification for status message.
5. Start full stroke test.
The 'Test information' status indicates
'Test active'. 'd6' and 'tEST' are indicated
in alternating sequence on the positioner
display. 'Function check'
as the condensed state.
