Error codes – Recommended action Condensed status alarm active, when prompted, Err appears.
54 Init – Solenoid valve 1) A solenoid valve is installed (Code 45 = YES) and was
not or not properly connected so that an actuator pressure
could not be built up. The alarm is generated when you
attempt to initialize the positioner.
2) If you attempt to initialize the device from the fail-safe
position (SAFE).
Recommended action Re. 1) Check connection and supply voltage of the solenoid
valve. Code 45 High/Low
Re. 2) Set the MAN operating mode over Code 0. Then initialize
the positioner.
55 Transit time <
The actuator transit times determined during the initialization are
so short that the positioner cannot adapt itself optimally.
Recommended action Check the volume restriction setting as described in section 4.1,
re-initialize the positioner.
56
Pin pos. Initialization was canceled because you are required to enter the
pin position for the selected initialization modes
NOM and SUb .
Recommended action Enter pin position over Code 4
and nominal travel/angle over
Code 5 . Re-initialize the positioner.
Operational errors
(indicated on the display by the condensed status with the corresponding classification)
57
Control loop Control loop error, the control valve does not react within the tol-
erable times of the controlled variable (tolerance band alarm
Code 19).
• Actuator mechanically blocked.
• Attachment of the positioner subsequently postponed.
• Supply pressure not sufficient.
Recommended action Check attachment.
58
Zero point Zero point incorrect.
Error may arise when the mounting position/linkage of the
positioner moves or when the valve seat trim is worn, especially
with soft-sealed plugs.
Recommended action Check valve and mounting of the positioner. If OK, perform a
zero calibration over Code 6 (see section 5.8 on page 71).
We recommend re-initializing the positioner in case of deviations
in the zero point over 5 %.
