6 FIGURE 3 FIGURE 4 FIGURE 5 6 MANUAL OVERRIDE INSTRUCTIONS To use the override, depress the override shaft and turn. NOTE: When the actuator is mounted to valves with a no-play coupling, the coupling has to be loosened before the override shaft of the EJ20, EJ50, EJX20 and EJX50 can be depressed. EJ90 and EJX90 overrides will work without loosening the no-play coupling screws. There are no mechanical rotational stops on the override. NOTE: Excessive force applied to the actuator manual override mechanism after the valve has reached its positive stop may damage the actuator, valve or both. After using the manual override check the valve/actuator unit by cycling several times and observing for proper operation. Neles-Jamesbury valves when factory mounted turn clockwise to close and counterclockwise to open unless otherwise specified by the customer. The EJ90 and EJX90 override mechanism works through a gear reduction. The override shaft will turn in the opposite direction from the valve. TROUBLE SHOOTING PROBLEM TRY THIS Motor will not run.
