Malfunctions
Example:
If, for instance, a travel has been entered in Code P5 (nominal range), which is larger than
the maximum valve travel possible, the rated travel cannot be reached during initialization
process. In this case, initialization is canceled. Closed-loop operation is continued if the posi-
tioner has already been initialized. When the positioner has not yet been initialized, the
valve returns to the fail-safe position (indicated by the
S icon). After Code P0 or P27 the er-
ror codes E2 (positioner not initialized) and E6 (rated travel not reached) are displayed.
S Display of the fault indication:
− Fault indication icon appears.
− Valve moves to the fail-safe position (indicated by the
S
icon).
S
E2 error code: Initialization canceled.
S
E6 error code: Rated travel not achieved.
The nominal range (Code P5) must be changed and the positioner re-initialized to remedy
this problem.
9.1 Troubleshooting
The errors listed in Table 9-2 are assigned to error classes:
− Error class 1: No operation possible
− Error class 2: Manual operation only possible
− Error class 3: Manual operation and closed-loop control possible
In TROVIS-VIEW, an additional icon for status classification is shown together with the error
(see Table 9-1).
