Attaching
Sensor
This section instructs how to attach sample tubing and wiring and start
using the RLPC.
WARNING:
Please
follow the standard
precautions for working
with liquids around
electronics.
Use of safety measures when working with liquids around electronics
cannot be stressed enough. Make sure the RLPC is physically secure
before connecting any tubing or electrical cables. Use Personal
Protection Equipment (PPE), such as face shields, protective
garments and gloves, whenever working around hazardous liquids.
1. Make sure that there is no flow of liquid in the system and power is
removed from the RLPC.
Note:
When connecting
flare fittings to the RLPC,
do
NOT use a wrench or
other tool to tighten the
flare nut! Doing so will
damage the instrument,
tubing or nut. The
connections
MUST be
finger-tight only.
2. Connect the liquid source to the RLPC’s Inlet nozzle using the
provided ¼" flare tubing. Make sure the tubing is inserted firmly
onto the nozzle and the knurled nut is finger tight only.
3. Connect the liquid drain to the RLPC’s Outlet nozzle using the
provided ¼" flare tubing. Make sure the tubing is inserted securely
onto the nozzle and the knurled nut is finger tight only.
4. Turn the liquid system on and allow liquid to flow through the
RLPC, making sure that there are no leaks at the sensor’s inlet or
outlet or any other connections.
WARNING:
If a leak
occurs anywhere within
the system, immediately
stop the flow of liquid
and repair the leak!
5. If leaks occur, immediately stop the flow of liquid. Disconnect and
clear the flare fittings and connectors of debris or burrs. Repair any
other leak(s), then return to Step 1 of this section.
6. If no leaks occur, connect power the RLPC.
7. Make sure the sample liquid is bubble-free - bubbles will be
counted as particles and in large amounts may cause sensor errors.
8. Allow liquid to flow through the sensor for 10 minutes or until
there are no bubbles and the Service LED is OFF. If the Service
LED comes on and remains on, the flow cell should be cleaned (see
Appendix B, “Maintenance” on page A-1 for cleaning instructions).
9. If there are no leaks and the service LED is off, the instrument is
ready to configure the communications - refer to Chapter 4,
“Programming” .
10. Adding devices or additional connections between the sample
source and the sensor will increase the chances for leaks and
bubbles - keep connections to a minimum.
