tube fitting.
2. Kits with fluid regulator: Check that the air tube
is connected from 5/32 tube fitting (AC) on I/P
transducer to 5/32 tube fitting (AH) on fluid
regulator (N).
Other Kits: The air outlet is 1/4 in npt (f).
The I/P transducer exhausts a small amount of air
whenever air is connected, whether or not the system
is operating.
NOTE:
• The side port (AD) on the fluid regulator can be
used for high-speed flushing with an independent
air source. Set the air pressure higher than the top
port (AH) air pressure.
• Flushing air pressure must be removed from the
side port (AD) to return to the previous flow setting.
• A Modbus Gateway (Graco Kit 24N977)
can be connected to (or installed in)
an Advanced Web Interface (Graco
Kit 15V377) to enable communication
with a PC using an ethernet cable. See
Appendix B - Advanced Web Interface, page
for instructions.
These communication kits come with installation
