WIRING OF VALVE POSITION TRANSMITTER
1. Remove VPT cover from the housing by loosening
the screws. Holding the housing and cover
assembly together, lift the cover from the housing.
2. Follow the wiring diagram located inside the cover
of the VPT. Be sure to secure all the appropriate
connections including the ground. The diagram at
left relates the wiring diagram to the terminal block.
3. Replace the VPT cover and tighten the screws. To
ensure that the shaft alignment mechanism
functions properly, bring all of the screws in contact
with the cover and then tighten them in stages
moving from one screw to its diagonal counterpart.
