This cancellation condition only becomes
effective after it has been activated ("Ac-
tivation 'Allowed time to reach full closed
position'" = Yes).
Additionally, the full stroke test is canceled
when one of the following events arises:
− 'Aborted by int. solenoid valve/forced
venting': The test was canceled by the
activation of the solenoid valve/forced
venting function.
− 'Supply pressure/friction': An insufficient
supply pressure or excessive friction oc-
curred during the test.
− 'Current too low' (not Types 3730-4/-5)
Note
The 'Measured data storage out of memory'
reading (Maintenance alarm) is generated
when the 'Scan rate' is too low. After record-
ing 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 cancellation 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
