3. Mounting

EA actuators are suitable for direct mount on ISO standard flanged valves and dampers.
There is no limitation in mounting actuator on valve. In a vertical pipeline, it is recommended that the conduit
entry is pointing downward in order to avoid water flow in through the cable entry.
When actuator is mounted on valve, the following procedure is recommended.

1> Watching the indicator, put actuator at fully closed position (Clockwise).
2> Valve stem must be properly machined to match with female drive shaft of actuator. An adapter may be
required.
3> Close the valve and mount actuator on valve.

4. Switch adjustment

1) Required tools for setting

Allen-Wrench 1 set(M2, Metric)

2) Manual operation

① Manual drive shaft is located at bottom of actuator. (AE 350)
② Clockwise direction is closed, Counterclockwise is open.
③ From fully closed position to fully open position requires approximately 9 turns.
④ Do not to manually operate the actuator past the setting of the limit switch.

3) Limit switch setting

1> Put actuator at fully closed position by watching indicator.
2> Turn the close cam until cam activates the lever of the limit switch and makes a “clicking” sound.
3> Tighten cam set screw(M2) to fix cam position.
4> Repeat for the open position
