This error will clear as soon as the valve position goes inside of the tolerable error. A deviation alert is informational only

alarm will be generated.

11.3 Travel Alerts

The Travel Alerts screen allows you to set limits on the travel of the valve. When valve travel exceeds either limit, an alert is
generated.

Travel Alerts

There are two settings that determine the upper and lower limits of this alert, the Low Setpoint limit and the High Setpoint
limit. To adjust the limits, type in the desired value or use the page up/down buttons on your keyboard. Press the

ton to activate the new limits in the positioner.

These alerts cannot be turned off, but they can be effectively disabled when set out of the active range of the valve travel.
The default setting of -10 for the Low Setpoint and 110 for the High Setpoint effectively deactivate these alerts. This alert will
clear as soon as the valve position goes inside of the set point limits. A travel alert is informational only and will not affect
the operation of the positioner or control valve.

The illustration at the bottom of the page is a graphical representation showing how these factors work and when an alert
