Electrically operate the valve in the open direction. If the valve closes, actuator must be stopped and
the power leads reversed to correct voltage phasing or improper field wiring.
Set all field conduit entries in accordance with National Electric Code Requirements
☞Improper power voltage phasing eliminates protection of both the position limit switch and torque
switches, risking valve damage.
