Figure 2-30. Example of FIELDVUE DVC6000 SIS Digital Valve Controller Installed in a 2-Wire SIS System (without a Solenoid Valve)
Make connections to the line conditioner as follows:
CAUTION
Do not overtighten the wiring
connection terminals or subject them
to heavy lateral (pushing) loads. This
could damage the line conditioner.
1. Be sure the digital valve controller DIP switch is set
for multi-drop operation.
2. Connect the digital valve controller LOOP +
terminal to the line conditioner FLD + terminal.
3. Connect the digital valve controller LOOP −
terminal to the line conditioner FLD − terminal.
4. Connect the solenoid valve field terminals to the
line conditioner FLD + and − terminals.
5. Connect the logic solver output to the line
conditioner SYS + and − terminals.
Note
Using the digital valve controller in a
2-wire system (multi-drop operation)
with an ASCO low-power solenoid
valve EF8316G303, EF8316G304,
EFX8553G305 103594 or EFX8551G305
103594 (or an equivalent low-power
solenoid valve) requires a line
conditioner. Using a low-power piloted
solenoid valve requires a separate air
supply.
When using an EF8316G303 or
EF8316G304 ensure that the solenoid
valve’s “selection gasket” is in the
“External Position”. The use of
external piloting requires the pilot
pressure to be at least 15 psig higher
than the main line pressure.
