Hardware Setup
2-14
Self-Test
The “F” address switch position is used to activate the XP 3000 self-test. Self-test causes
the XP 3000 to initialize then cycle repeatedly through a series of plunger movements at
fifteen different speeds. If an error condition occurs, the pump stops moving. Typically,
the self-test activates the pump at 800 strokes/hour.
To run the self-test, set the address switch to position “F.” If the pump carries microstep-
enabled firmware, the configuration jumper JP1-3 must also be installed. Then supply
power to the pump.
CAUTION! Always run liquid through the syringe and valve. Failure to do so can
damage the valve and syringe seal.
Do not run self-test with a 5.0 mL syringe installed. Remove the valve
and 5.0 mL syringe. Failure to do so can result in plunger overloads.
Inputs/Outputs
The XP 3000 provides two auxiliary inputs and three auxiliary outputs that can be
accessed through the DB-15 connector, JP3. They provide TTL level signals. The outputs
are controlled by the [J] command.
The auxiliary inputs are located on JP3 pins 7 and 8. They can be read back using report
commands ?13 and ?14. Additionally, the inputs can be used to externally trigger a
command sequence using the [H] command. The commands are described in Chapter 3,
“Software Communication.”
The auxiliary outputs are located on JP3, pins 13, 14, and 15.
