D Travel Alert Hi Hi Point—The value of the travel, in percent (%) of ranged travel, which, when exceeded, sets the Travel
Alert Hi Hi alert.
D Travel Alert Lo Lo Point— The value of the travel, in percent (%) of ranged travel, which, when exceeded, sets the
Travel Alert Lo Lo alert.
Travel Limit Hi/Lo Alerts—Travel Alert Hi is set if the ranged travel rises above the alert high point. Once the alert is set,
the ranged travel must fall below the alert high point by the Travel Alert Deadband before the alert is cleared. See
figure 4‐2.
Travel Alert Lo is set if the ranged travel falls below the alert low point. Once the alert is set, the ranged travel must rise
above the alert low point by the Travel Alert Deadband before the alert is cleared.

D Cutoff Hi
Travel Cutoff Hi defines the high cutoff point for the travel in percent(%) of pre‐characterized set point. Above this
cutoff, the travel target is set to 123.0% of the ranged travel. Travel Cutoff Hi is deactivated by setting it to 125.0%.
Pressure Cutoff Hi defines the high cutoff point for the pressure in percent (%) of pre‐characterized set point. Above
this cutoff,the pressure target is set to 123.0%. A Pressure Cutoff Hi of 99.5% is recommended to ensure valve goes
fully open. Pressure Cutoff Hi is deactivated by setting it to 125%
D Cutoff Lo
Travel Cutoff Lo defines the low cutoff point for the travel in percent (%)of pre‐characterized set point. Below this
cutoff, the travel target is set to -23%. A Travel Cutoff Lo of 0.5% is recommended to help ensure maximum shutoff
seat loading. Travel Cutoff Lo is deactivated by setting it to-25.0%
Pressure Cutoff Lo defines the low cutoff point for the pressure in percent (%) of pre‐characterized set point. Below
this cutoff,the pressure target is set to -23%. A Pressure Cutoff Lo of 0.5% is recommended to help ensure maximum
shutoff seat loading. Pressure Cutoff Lo is deactivated by setting it to -25.0%
D Change Cutoffs—Allows you to set Cutoff Hi and Cutoff Lo. When a cutoff is set the corresponding travel or pressure
limit is disabled.
D Travel Limit High—Defines the high limit for the travel in percent (%) of ranged travel. It is the maximum allowable
travel (in percent of ranged travel) for the valve. During operation, the travel target will not exceed this limit. When
a Travel Limit High is set, the Travel Cutoff High is deactivated, since only one of these parameters can be active.
Travel Limit High is deactivated by setting it to 125.0%.
