P/N 335-3261 (Sporlan SEI and Emerson Flow Con- trols ESR Stepper Valve)

The 335-3261 valve cable is equipped with a four-pin male connector that plugs into a four-pin female connector on the valve. Plug the valve cable connector into the valve connector.

P/N 335-3260 (Generic Stepper and Emerson Flow Controls ESV Valve)

The 335-3260 valve cable has six flying leads for con- nection to a stepper valve. Four of these leads connect to the stepper motors, while the other two serve as the power wiring (+12VDC and ground).

The pinout for this valve cable is shown in Figure 9- 17. Table 9-5shows how to hook the flying leads to Emer- son Flow Controls ESR, Emerson Flow Controls ESV, and Sporlan SEI & CDS valves.

9.4ESR8 Valve Output Wiring

The stepper valves are wired to the board by connect- ing the four-conductor wire from the stepper valve to a connector plug and then plugging in to one of eight jacks

along the top of the board Figure 9-18.Use the cable har- nesses supplied with the valves or use Belden #9418 four- conductor 18AWG wire.

NOTE: A wire run may not be longer than 150 ft. using Belden #9418.

If the stepper valves have block-style connectors, cut the ends off and attach the terminal plugs supplied with the ESR8 to the wire ends.
