Multi-Pump Configurations
Up to fifteen XP 3000s can be connected together in a
multi-pump configuration
(also
called “daisy-chaining”). Within a multi-pump configuration, the RS-485
communications bus is required, although the first pump in the chain may receive either
RS-232 or RS-485 communications. For CAN communication, neither RS-232 or RS-485
is required. Each pump can be addressed separately from a single terminal via its unique
address, which is set using the address switch on the back panel of the pump. For more
information on setting addresses, see Chapter 2, “Hardware Setup.” For XPs with
microstep-enabled firmware, up to 16 XP 3000s can be connected together in a multi-
pump configuration.
Valve Sensor
The XP 3000 sensor board includes a circuit that detects fluid leakage out the back of the
valve. The valve is made of a Kel-F body and a Teflon plug which rotates inside the
body. Over time, the plug wears, causing the valve to leak. The length of time before
leakage occurs depends on the type of fluids used, duty cycle of the pump, and
maintenance procedures. The circuit will detect conductive fluid (i.e., ionic solution). On
power-up, the valve leak detector is set to 0, which means it is disabled. The user sets the
sensitivity of the leak detector. If fluid is detected, the pump returns an error code.
Tips for Setting Up the XP 3000
For complete information on setting up the XP 3000, see Chapter 2, “Hardware Setup”
and Chapter 3, “Software Communication.”
To ensure proper operation, follow these tips:
G
Always set up and mount the pump in an upright position. Failure to do so can cause
problems priming the system.
G
Always run liquid through the syringe and valve when they are moving. Failure to do
so can damage the sealing surfaces.
G
Before running any organic solvents through the pump, see Appendix D, “Chemical
Resistance Chart” for more information on solvents.
G
Keep fingers out of the syringe slot while the pump is running. Failure to do so can
cause injury.
G
Always power down the instrument when connecting or disconnecting pumps.
