760-162-G1/G2
On the relay connector, connect the leads of the solenoid valve across the one side
of a 24 volt supply and one side of a relay (1-8, 1-16, or 1-24; whichever was
programmed). See
Table 2-1 .
CAUTION
Both the isolated 24 V(dc) supply and the RS-232C
remote communications port use a 9-pin D-sub
connector. Care must be taken not to inadvertently
connect the RS-232C remote communications cable to
the 24-volt supply connector. Also, care must be taken
not to inadvertently connect the 24 V(dc) supply cable to
the RS-232C remote communications connector.
Connect a jumper between the second side of the 24 volt supply and the second
side of the selected relay. See
