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.
6.2 Start/Stop Triggers
The Pumping Program can be started or stopped from 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.
6.3 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.
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complete after the set volume has been infused or withdrawn, measured from the start of the Phase.
The display can be changed by pressing the ‘Rate’, ‘Volume’, or ‘Diameter’ keys.
6.4 Purging
To purge the syringe, with the Pumping Program stopped, press and hold the 'Start/Stop' key. The Pumping
Program will start, then after one second purge will begin. The pump will pump at its top speed in the
currently set direction. Purging will continue until the 'Start/Stop' key is released, and then the pump will stop.
While purging the display will show: .
6.5 Changing the Pumping Rate and Direction While Pumping
Except with some complex Pumping Programs, the pumping rate can be changed while the pump is operating.
To change the pumping rate, display the pumping rate by momentarily pressing the ‘Rate’ key. With the
pumping rate is displayed, press the up arrow keys to change the rate. The rate units will blink while entering
the rate. Rate units cannot be changed while pumping.
The new rate is stored after a 2 second delay or by pressing a non-arrow key. If the new rate is within the
operating range of the pump, the display will blink and the new rate will be stored in the current Program
Phase and the pump will begin to pump at the new rate. If the new rate is out of the operating range of the
pump, the display will show
nn
. Pressing any key clears the error message.
The pumping direction can be changed while pumping if the “Volume to be Dispensed” is 0.0 (off). Pressing
the direction key will immediately change the pumping direction and store the pumping direction in the current
Program Phase. Also changing the pumping direction changes the accumulated “Volume Dispensed”
according to the new pumping direction.
6.6 Volume Dispensed
When the total accumulated volume pumped is displayed, the ‘ml’ or ‘ µl’ LED is lit and the ‘Dispensed’ LED
is lit. Volume is computed based upon the syringe inside diameter setting. The accumulated Volume
Dispensed can be displayed by pressing the ‘Volume’ key one, two, or three times, depending on the current
display.
The volume is accumulated separately for infusion and withdrawal. When the pump changes direction, the
“Volume Dispensed” changes to the accumulated volume for the current pumping direction.
The “Volume Dispensed” accumulations for infusion and withdrawal are reset to 0 when:
A) With the pump stopped, pressing and holding any up arrow key while displaying the “Volume
Dispensed”.
B) A sub-program is selected when the Pumping Program executes a Program Selection function.
C) The syringe diameter is changed.
D) From the RS-232 clear “Volume Dispensed” command (CLD) or Clear Dispense function.
E) The accumulated Volume Dispensed rolls over from 9999 to 0.
F) The pump is powered on.
