For configuring the actuator:
1. Place the red knob in the “STOP” position.
2. Move the black knob to the “YES” or “NO” position and release to answer questions appearing on the LCD display.
The OPEN and CLOSE position limits must be set after the actuator has been mounted on the valve. See Section 3.5.4,
Setting Position Limits. All other actuator parameters are factory-set either in accordance with a Limitorque standard
set of default values (see Section 3.5.1, Default Configuration Set) or the requirements specified with the purchase
order. Reconfirm these preconfigured settings prior to placing the actuator into service since the requirements of the
application may have changed after the manufacture of the actuator. See Section 3.5.2, View the Existing Settings.
