seconds, the unit will reset.
4. Use the black control knob to answer “YES” or “NO” to the questions appearing in the display.
2.1.2 Electrical Operation Feature
This feature allows for quick and simple calibration. To set the position limits electrically, enter the “CHANGE SETTINGS”
mode via the “SETUP” mode.
1. Enter the “SETUP” mode as detailed in Section 2.1.1, Entering the Setup Mode.
2. When screen prompt reads “CHANGE SETTINGS,” select “YES.”
3. The screen will display the “CHANGE SETTINGS” mode menu items. Select “NO” until screen displays “CHANGE
POSITION SETUP.” User may select to set close limit first or open limit first.
4. Select “YES.” “CLOSE” or “OPEN VALVE - OK?” is displayed.
5. Place the red selector knob in the “LOCAL” position. Move the black knob in the intended direction. The LCD
screens are shown in Figure 2.1.
6. When valve has reached desired position, return the red selector switch to “STOP” and complete calibration.
The position settings are now complete. The actuator will now function as ordered, and may be run electrically to
inspect for correct operation.
a CAUTION: On some valves, position limits could be set adjacent to each other, so be careful that the Close and
Open limits are set sufficiently apart to permit operation. If the limits are set adjacent of each other, an error
message will be displayed: “KEEP OPEN(CLOSE) LIMIT?”
NO FURTHER MOVEMENT IS PERMITTED UNTIL THE ERROR IS CORRECTED.
Should the User elect to proceed with the setting, an error will be displayed on the screen after re-booting
stating “IDENTICAL LIMITS”. THE ACTUATOR WILL NOT MOVE UNTIL THE ERROR IS CORRECTED.
