4.6 Torque Setup
The output torque can be changed between 40% and 100% of the rated torque as follows:
1. From “VALVE SETUP?” or “CHANGE TORQUE TIMER?” (if enabled) select “NO” to enter the “TORQUE SETUP?”
routine.
2. Select “YES” to change the settings.
If “NO” is selected, the “POSITION SETUP?” routine will be entered.
NOTE: Except for arctic temperature actuators (-30°C or below), which permit torque to be changed from 60%-100%.
4.6.1 Close Torque Valve or Open Torque Valve
The output torque from the actuator to close or open the valve may be configured between 40% and 100% of the rated
torque (as stated on the actuator nameplate), in 1% increments (unless limited by the factory).
To Increase the % of Torque Required:
1. Select “NO” until the desired % is indicated.
2. Select “YES” to save the required torque.
Should the user select a maximum torque setting less than 100% due to valve or gearbox limitations, this selection can
be password protected.
