Warnings and Alarms
Position Amplitude
•
Definition: The amplitude of the position signal is above the warning
limit. The positioner is controlling the position of the valve with large
corrections.
•
Possible Solutions: Verify the limits are set at an appropriate level.
Adjust the selectable Gain switch to a lower setting or use the "Hi
Friction" setting. Perform a QUICK-CAL which sets the gains based on
valve response. Check for high friction. If the problem persists replace
the relay.
