WARNING
!
Improper power voltage phasing eliminates protection of both the position limit switch and
torque switches, risking valve damage.
10
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.
