12.8 The Actuator Does Not Stop in 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.
• Make sure that the torque and travel limits are correctly set (see Section 9.1,
Set-up routines - Actuator set-up).
12.9 The Numeric Position Display Indicates “E01”
It is necessary to recalibrate the stroke limits (see Section 9.1, Set-up routines -
Actuator set-up).
12.10 Diagnostic Messages
The alarm and warning lists contain the alarms and warnings momentarily present.
Warning is the condition that occurs when a variable reaches a critical value and/or when a
maintenance action is required but all actuator functions are still available. The ashing of
the alarm/warning LED indicates a warning condition.
Alarm is the condition that occurs when a variable is outside the acceptable range and
some actuator function is not available. If the alarm/warning LED is on there is an alarm
condition. When the fault condition disappears, the corresponding alarm or warning also
disappears from the list.
A reset routine is provided to clear the types of alarms and warnings that are memorized
(over-torque, jammed valve, etc.).
