7. Operation
Before the pump can be operated, the pumping data must be setup. At minimum, the syringe
inside diameter and a non-zero pumping rate needs to be set. The operation of the pump can
then be started from the keypad, TTL I/O connector, or from RS-232 control. From the
keypad, pressing the ‘Start / Stop’ key will start the pump operation.
7.1 Syringe Inside Diameter
The syringe inside diameter can only be set while the Pumping Program is stopped. Use the arrow keys to
set the diameter value. While the diameter value is being set, the ‘mm’ LED will blink. The new diameter
value is stored after pressing any non-arrow key, or after a 2 second delay.
Valid syringe diameters are from 0.1 mm to 50.0 mm. If the diameter is out of this range, the display will
show ‘oor’. Pressing any key restores the diameter display to its previous value. Changing the syringe
diameter will not zero any current settings. Section 12.7, “Syringe Diameters and Rate Limits”, is a
representative list, for reference, of syringe diameters for various syringe manufacturers and syringe sizes.
7.1.1 Default Volume Units
The units of the accumulated infusion and withdrawal volumes and the “Volume to be Dispensed” are set
according to the diameter setting. NOTE: A change in the volume units will affect all “Volume to be
Dispensed” settings in the Pumping Program. If the default volume units are changed (see next section),
the selected volume units will remain in affect until a reset function is performed.
From 0.1 to 14.0 mm Syringes smaller than 10 ml: Volume units are ‘ l’
From 14.01 to 50.0 mm Syringes greater than or equal to 10 ml: Volume units are ‘ml’
7.1.2 Changing Volume Units
The volume units used for accumulated volumes and the “Volume to be Dispensed” settings can be
changed to either ‘ml’ or ‘
l’. NOTE: Volume units can only be changed immediately after setting the
syringe diameter and before the pump is started. A change in the volume units will affect all “Volume to
be Dispensed” settings in the Pumping Program.
After the syringe diameter is entered, display the “Volume Dispensed” by pressing the “Volume” key
twice. The current volume units and the “Dispensed” LED will be lit.
Pressing any arrow key will change the display to and the current volume units will blink.
Then, press any arrow key to switch the volume units between ‘ml’ and ‘ l’. Press any non-arrow key or
wait 2 seconds to enter the new volume units. The display will blink when entered. The selected volume
units will remain in affect and override the default volume units. Changing the diameter will no longer
change the volume units. Performming a system reset will cancel the override and allow the volume units
to change to the default volume units when setting the syringe diameter.
7.2 Start/Stop Triggers
The Pumping Program can be started or stopped from any of the three sources: The keypad ‘Start/Stop’
key, RS-232 ‘RUN’ command, or the TTL I/O Operational Trigger input. Each can control the Pumping
Program’s operation.
7.3 Operating the Pump
When the “Start/Stop” key is pressed, the Pumping Program begins to operate, starting with Phase 1. If the
current Program Phase specifies a pumping rate, the pump will begin pumping, and the ‘Pumping’ LED
will be lit. The pumping direction will depend on the Phase setup. The display will show the “Volume
Dispensed” with a volume units LED (‘ml’ or ‘
l’) and the ‘Dispensed’ LED lit.
While pumping, the pump will pump continuously in the current Program Phase, unless a “Volume to be
Dispensed” is set, or an Event trigger is set. If a “Volume to be Dispensed” is set, the Program Phase will
be complete after the set volume has been infused or withdrawn, measured from the start of the Phase.
