15. Ethernet Port – An 8P8C jack for a network connection
using a standard CAT5 cable, or for a direct connection to a
computer using a cross-over cable.
16. USB Port – For control of peripheral equipment such as
+
the Rf 4x or PurIon mass spectrometer detector. This rear
panel port is also used in service-related functions.
17. Cooling Fan – Cools the internal electronic assemblies.
Do not touch the fan.
18. Solvent Level Sensing Outlet Ports – uses air or
user-supplied gas to measure the hydrostatic pressure of
the solvent above the weighted tubing outlet. The ports are
not present on the Rf 150 systems.
19. Solvent Inlet Ports – Accepts A and B solvents. The Rf
150 system does not use the 4-port block. Refer to Section
3.4 for more information on Rf 150 solvent inlet ports.
20. Optional External Gas Port – An inlet for an internal
pump which supplies pressurized air or user-supplied gas
for solvent level sensing, waste container full detection,
and system/column purges. The external gas should be
regulated to 2–5 psig before connecting the source to this
port. The port is not present on the Rf 150 systems.
21. Mains Power – Connects the system to AC line voltage.
22. Waste Ports – From left to right:
• Waste Level Sense – The system uses air or
user-supplied gas to measure the hydrostatic
pressure of the waste above the level sense line end.
The system will suspend operation when this level is
too high. This port is not present on the Rf 150
systems.
• Diverter Valve Waste – The diverter valve on the
fraction collector arm sends fluid to this waste port.
• Inject Valve Waste – The injection valve is cleaned
after each run. The system directs fluids from this
automatic cleaning routine to this port.
