8.1 Basic Settings
8.1.1 Valve Tag
User defined name for the actuator consisting of up to 32 alpha-numeric or symbolic characters. It is
normally used by operators to specify a unique tag based on location or a description of the actuator.
8.1.2 Close Action
The actuator can be configured to close on pressure for seating valve types or limit for non-seating valve
types. Limit means the actuator will stop moving once it reaches the set closed position limit. Pressure
means the actuator will stop when it reaches the set closed pressure limit.
8.1.3 Open Action
The actuator can be configured to open on pressure for back-seating valve types or limit for non-back
seating valve types. Limit means the actuator will stop moving once it reaches the set open position
limit. Pressure means the actuator will stop when it reaches the set open pressure limit.
8.1.4 Close Pressure (Limit) (%)
This setting is the maximum cut-off pressure while travelling from the closed limit to the mechanical
end stop. The value set is a percentage of the maximum available pressure, which is limited by the
pressure relief valve.
8.1.5 Close Pressure (Mid) (%)
This setting is the maximum mid-travel cut-off pressure, between the open and closed limit, while
travelling in the close direction. If the value is set to 0, the pressure-off value from 8.1.7 Open
Pressure is used.
8.1.6 Open Pressure (Limit) (%)
This setting is the maximum cut-off pressure while travelling from the open limit to the mechanical end
stop. The value set is a percentage of the maximum available pressure, which is limited by the pressure
relief valve.
8.1.7 Open Pressure (Mid) (%)
This setting is the maximum mid-travel cut-off pressure, between the closed and open limit, while
travelling in the open direction. If the value is set to 0, the pressure-off value from 8.1.5 Close
Pressure is used.
8.1.8 Closed Limit
This setting shows the raw positional value for the set closed limit. Rotork Service Engineer use only.
8.1.0 Open Limit
This setting shows the raw positional value for the set open limit. Rotork Service Engineer use only.
