12.9 The Actuator does not Stop in the Fully Open
or Fully Closed Position
• Check that the actual open and close positions of the valve respectively
correspond to 100% and 0% on the actuator display.
• Ensure that the torque and travel limits are correctly set (see Section 9.1,
Set-up routines - Actuator set-up).
12.10 The Numeric Position Display Indicates "---"
• Stroke limits must be re-calibrated (see Section 9.1, Set-up routines - Actuator set-up).
12.11 Diagnostic Messages
The alarm and warning lists contain the alarms and warnings momentarily present.
A Warning is a condition that occurs when a variable reaches a critical value and/or when a
maintenance action is required but all actuator functions remain available. The Warning icon
on the lower display and the ashing of the alarm/warning LED indicate a warning condition.
An Alarm is a condition that occurs when a variable is outside its acceptable range and/or
some actuator functionality is not available. The Alarm icon on the lower display and the
alarm/warning LED ON indicate an alarm condition. When the fault condition disappears,
the corresponding alarm or warning also disappears from the list.
A reset routine is available to clear certain types of alarms that are memorized by the
actuator (over-torque, jammed valve, etc.).
