Cavro® XLP 6000 Modular Syringe Pump Operating Manual, 734237-C, en
J5 Inputs/Outputs
The XLP 6000 provides two auxiliary inputs and three auxiliary outputs that can be
accessed through the DA-15 connector, J5. They provide TTL level signals. The
outputs are controlled by the [J] command.
The auxiliary inputs are located on J5, 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 J5, pins 13, 14, and 15.
Installing Components
Installing the XLP 6000 Valve
To install the XLP 6000 valve, follow these steps:
1
Remove as much fluid as possible from the system by cycling the pump and
using air as the system fluid.
2
Initialize the pump using the [ZR] command so that the valve motor shaft is in
the correct position.
3
Issue an [A6000R] command to move the plunger to the bottom of travel.
4
Remove the syringe and tubing.
5
Remove the two socket head screws on the front of the valve, then remove
the valve from the pump. Do not remove the spacer.
6
Install the new valve by placing it on the front panel so that the screw holes
line up. The valve coupler fitting mates to the valve motor shaft. The shaft
should be in the correct position. If it is not, re-initialize the pump using the
command [ZR].
7
Replace the valve screws but do not tighten completely.
8
Install the syringe and pull the syringe plunger until it is aligned with the
carriage. Align the valve using the plunger as a guide, and tighten from 1/4 to
1/2 turn after the screws contact the valve body.
9
Pull the syringe plunger all the way into the carriage and secure by tightening
the plunger lock screw.
Caution! Be sure to reconfigure the pump firmware when changing valve types.
Failure to do so may damage the valve. See Section 3.3.2, Pump Configuration
Commands, for instructions on reconfiguring the pump.
