1. Move the red knob to “LOCAL” and move the black knob in the intended direction. LCD display will read:
OR
CLOSE VALVE
RETURN TO STO P
OPEN VALVE
RETURN TO STO P
2. Once the “CLOSE” or “OPEN” valve position limit has been reached, return the red knob to “STOP” and complete
setting the “CLOSE” or “OPEN” position limit. See Figure 3.23.
NOTE: Once the travel limits have been set, the actuator may be operated electrically from the remote inputs. Local
maintained operation is also permitted. Check the operation of the actuator to ensure that the torque and limit settings
are satisfactory. Place the selector switch in “LOCAL” and rotate the “OPEN/CLOSE” switch to operate the actuator in the
“MOTOR” mode.
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 to 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.
