Section 9: Electrical Connection
•
Move valve to mid-position by handwheel. This will allow sufficient time to stop
actuator in case of improper hook-up or reversed power phases.
•
Identify means of removing power during hookup.
•
Be sure no erroneous remote control signals can be received causing actuator
to energize.
•
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.
!
WARNING
Improper power voltage phasing eliminates protection of both the position limit switch and
torque switches, risking valve damage.
